Fortschritts haben Veränderungen in einer Art und Weise zur Folge, wo alles möglich erscheint bezogen auf die genutzten Materialtechnologien innerhalb des Feldes der modernen Bilder. Die "Frau in Weiß" ist ein Bild von Gabrijel Stupica, das Teil seiner Reihe "die Bräute" ist. Es wurde in der Tempera Papiertechnik um 1975 erstellt. Die Farboberfläche ist bröckelig und blättert ab, der Träger ist empfindlich gegenüber Feuchteeintrag sowie faltig und an bestimmten Stellen abgerissen. Wenn der Künstler gegen die etablierten Regeln oder Standards der Kunsttechnologien ist, dann müssen diese Prozeduren auch vom Restaurator akzeptiert werden und er muss das Kunstwerk in einem professionellen und angemessenen Weg restaurieren.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="8fb35b4d644d0e45afeadd6a93aeae80" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":112518430,"asset_id":116368130,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/112518430/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116368130"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116368130"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116368130;

In this investigation the adsorption of aspartic acid (Asp) and lysine (Lys) onto SPIONs was studied, based on a characterization of the suspension properties, i.e., measurements of the ξ-potential, the hydrodynamic size, and the osmolality, and by direct HPLC analysis of the AA in the supernatants and at the nanoparticles of the ultracentrifuged suspensions. The results show that the AAs adsorb onto the SPIONs in the form of large molecular associates, which decisively influence the nanoparticles’ surface properties. A measurement of the freezing-point depression using a Knauer osmometer proved that the molecular associates are already formed in the AA aqueous solutions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116368119"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116368119"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116368119; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116368119]").text(description); $(".js-view-count[data-work-id=116368119]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116368119; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='116368119']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=116368119]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":116368119,"title":"Adsorption of Amino Acids, Aspartic Acid, and Lysine onto Iron-Oxide Nanoparticles","internal_url":"https://www.academia.edu/116368119/Adsorption_of_Amino_Acids_Aspartic_Acid_and_Lysine_onto_Iron_Oxide_Nanoparticles","owner_id":277533442,"coauthors_can_edit":true,"owner":{"id":277533442,"first_name":"Irena","middle_initials":null,"last_name":"Kralj Cigic","page_name":"IrenaKraljCigic","domain_name":"uni-lj","created_at":"2023-07-20T03:21:31.212-07:00","display_name":"Irena Kralj Cigic","url":"https://uni-lj.academia.edu/IrenaKraljCigic"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="116368114"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/116368114/Accumulation_and_Transformation_of_Biogenic_Amines_and_Gamma_Aminobutyric_Acid_GABA_in_Chickpea_Sourdough"><img alt="Research paper thumbnail of Accumulation and Transformation of Biogenic Amines and Gamma-Aminobutyric Acid (GABA) in Chickpea Sourdough" class="work-thumbnail" src="https://attachments.academia-assets.com/112518380/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/116368114/Accumulation_and_Transformation_of_Biogenic_Amines_and_Gamma_Aminobutyric_Acid_GABA_in_Chickpea_Sourdough">Accumulation and Transformation of Biogenic Amines and Gamma-Aminobutyric Acid (GABA) in Chickpea Sourdough</a></div><div class="wp-workCard_item"><span>Foods</span><span>, 2021</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In general, sourdough fermentation leads to an improvement in the technological, nutritional, and...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">In general, sourdough fermentation leads to an improvement in the technological, nutritional, and sensory properties of bakery products. The use of non-conventional flours with a specific autochthonous microbiota may lead to the formation of secondary metabolites, which may even have undesirable physiological and toxicological effects. Chickpea flours from different suppliers have been used to produce sourdoughs by spontaneous and inoculated fermentations. The content of nutritionally undesirable biogenic amines (BA) and beneficial gamma-aminobutyric acid (GABA) was determined by chromatography. Fenugreek sprouts, which are a rich source of amine oxidases, were used to reduce the BA content in the sourdoughs. Spontaneous fermentation resulted in a high accumulation of cadaverine, putrescine, and tyramine for certain flours. The use of commercial starter cultures was not effective in reducing the accumulation of BA in all sourdoughs.

In this work, we examine the potentials of mid-and near-infrared spectroscopy, however, in order to fully utilise the selectivity inherent to spectroscopic multivariate measurements, genetic algorithms were used to select spectral data derived from information-rich FT-IR or UV-VIS-NIR measurements to build multivariate calibration models based on partial least squares regression, relating spectra to gelatine content in paper. A selective but laborious chromatographic method for the quantification of hydroxyproline (HYP) has been developed to provide the reference data on gelatine content. We used 9-fluorenylmethyl chloroformate (FMOC) to derivatise HYP, which was subsequently determined using reverse-phase liquid chromatographic separation and fluorimetric detection. In this process, the sample is consumed, which is why the method can only be used as a reference method. The sampling flexibility afforded by small-size field-portable spectroscopic instrumentation combined Published in Talanta 82 (2010) 1784-1790 2 with chemometric data analysis, represents an attractive addition to existing analytical techniques for cultural heritage materials.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="25712225814413350388ad91d9988ab4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490834,"asset_id":113563027,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490834/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563027"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563027"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563027;

The weight average molar mass was determined for a collection of 57 samples, ranging from 75 to 186 kg/mol with a median of 102 kg/mol. Rigid PVC objects were found to have a significantly lower weight average molar mass (M w = 81 kg/mol) than plasticized ones (M w = 102 kg/mol). Thin objects also exhibited significantly lower M w than bulky objects. A substantial presence of aggregates was noted and characterized as an 'aggregate ratio' for the entire collection. Heating a solution of poly(vinyl chloride) in THF at 55 °C for 5 h proved successful in the dissociation of the aggregates and allowed for an accurate determination of molar mass. The uncertainty of the M w determination was statistically evaluated and used to study the effects of accelerated degradation on M w. No statistically significant changes in M w were observed in samples artificially aged at 50 °C to 80 °C for up to 15 weeks, indicating that M w does not decrease during degradation of a PVC heritage object and that accelerated degradation does not lead to polymer crosslinking.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b5950302713ed0671749073cc39299da" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490874,"asset_id":113563026,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490874/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563026"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563026"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563026;

For the first time, a large and diverse collection of more than 100 PVC objects in different degradation stages and of diverse chemical compositions was analysed by chromatographic and spectroscopic techniques to create a dataset used to construct classification and regression models. Accounting for this variety makes the model more robust and reliable for the analysis of objects in museum collections. Six different machine learning classification algorithms were compared to determine the algorithm with the highest classification accuracy of the most common plasticizers, based solely on the spectroscopic data. A classification model capable of the identification of di(2-ethylhexyl) phthalate, di(2-ethylhexyl) terephthalate, diisononyl phthalate, diisodecyl phthalate, a mixture of diisononyl phthalate and diisodecyl phthalate, and unplasticized PVC was constructed. Additionally, regression models for quantification of di(2-ethylhexyl) phthalate and di(2-ethylhexyl) terephthalate in PVC were built. This study of real-life objects demonstrates that classification and quantification of plasticizers in a general collection of degraded PVC objects is possible, providing valuable data to collection managers. Poly(vinyl chloride) (PVC) is a modern polymeric material and one of the most widely used plastics today 1. Since its commercialization, it has been used in a variety of applications, including clothing, toys, tubing and piping, flooring, and medical devices 2,3. Plasticizers are used to improve and adjust the mechanical properties of the material by increasing flexibility, reducing viscosity, and decreasing friction during manufacture. Plasticizers can account for up to 50% of the total mass of PVC objects 4-6. Because of its versatility PVC has also been used as a material for artworks 4,7,8 and represents a significant part of modern and contemporary collections 9. The challenges of preserving PVC are well recognised in the literature 10-12 , and some are related to the plasticizers in the material 13. There are reported cases of plasticizer accumulating on the surface, which can trap dust and dirt, as well as plasticizer loss, which can cause warping, cracking, and structural failure 7,13-15. Phthalates, terephthalates, adipates, trimellitates, and citrates represent the majority of commercially-used plasticizers. Dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), di(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), di(2-ethylhexyl) terephthalate (DOTP), di(2-propylheptyl) phthalate (DPHP), and diisononyl cyclohexane-1,2-dicarboxylate (DINCH) were found as the most interesting plasticizers based on their properties, historic significance and market popularity (Supplementary Fig. S1). Market popularity has shifted over the decades mainly due to legislation changes in Europe and the USA. DBP and DIBP are short-chain phthalate plasticizers that have been primarily used in combination with DEHP and DINP 16. DBP is a suspected endocrine disruptor, so its usage is regulated and restricted for use in toys in the EU 17. DEHP had been used as a general-purpose plasticizer for all consumer products, including toys, food contact material, cosmetics, medical devices and household products. In 2008, it was classified as hazardous in Europe 18 and the USA, and was replaced by higher molecular weight phthalates (DINP and DIDP) as general-purpose plasticizers. DOTP is a terephthalate isomer of DEHP, with similar plasticization abilities, but is subject to less regulatory restrictions</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="903d1be026b49b07e13d825c4fc50048" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490833,"asset_id":113563025,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490833/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563025"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563025"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563025;

A novel theoretical model using Hansen solubility parameters as the basis for a complete mathematical derivation of the model was developed. The theoretical model also includes the cavitation volumes of the analytes, which were calculated using ab initio density functional theory methods. A set of three homologous phthalates was used for experimental data collection and subsequent model construction. The training error and the generalization error of the model were additionally evaluated using a range of chemically diverse analytes. Statistical evaluation of the results revealed that the model is suitable for analyte retention prediction but is limited to the analytes used in the model construction. Therefore, the resulting theoretical model cannot be easily generalized. A retention anomaly attributed to the column temperature and mobile phase composition was experimentally observed and mathematically investigated.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5c23e9c05869aa8acde9b80f295cb7f6" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490836,"asset_id":113563024,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490836/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563024"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563024"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563024;

Due to their poor biodegradability of these contaminants in municipal wastewater treatment plants, additional advanced oxidation processes such as electrochemical treatments have been developed to improve the standard biological treatment. Here we review the applications of electrochemical treatments of wastewater for the removal of the following plastic contaminants: bisphenol A, phthalic acid esters, and benzotriazoles. We present the effectiveness of treatment in terms of contaminant removal and mineralization; the identification of transformation products; toxicity assessment; and process energy requirements. In the present review, we have focused on the applications of electrochemical treatments of wastewater for the removal of three important groups of contaminants originating mainly from plastics: bisphenol A, phthalic acid esters, and benzotriazoles. The review focuses on the research of electrochemical treatments for these contaminants from the last five years. The papers are assessed from the point of i) effectiveness of treatment in terms of contaminant removal and mineralization; ii) identification of transformation products; iii) toxicity assessment; iv) processes' energy requirements. Electrochemical treatments were confirmed to be a viable option for the removal of selected contaminants from wastewater.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="94ee195f544426fdb134152d49bc0566" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490830,"asset_id":113563023,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490830/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563023"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563023"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563023;

However, little is known about its material properties, especially given the many grades of sized and unsized Xuan paper. In addition, there is a lack of information on its degradation. In this research, a selection of contemporary unsized Xuan papers was investigated, representing diverse raw materials. Seven out of twelve contemporary unsized Xuan papers were determined to be approximately neutral and contain[2% alkaline reserve, indicating good durability. Viscometry was used to determine the degree of polymerisation (DP) as none of the samples gave significant reactions to the phloroglucinol spot test. The average DP of ten contemporary unsized Xuan papers is~1700, excluding two papers that have presumably been sun-bleached, and that exhibit significantly lower DP. Using X-ray fluorescence, it can be demonstrated that Ca and Si are the dominant elements and interestingly, Ca content is directly correlated with ash content and with alkaline reserve. Accelerated degradation was performed at two sets of environmental conditions, i.e. 90°C, 30% RH and 60°C, 70% RH, and the established degradation rates agreed with the Collections Demography model of paper degradation meaning that degradation of Xuan papers proceeds in the same way as other types of paper. This research gives fundamental insights into contemporary unsized Xuan papers, which exhibit good stability during accelerated degradation despite the low starting DP in the context of the samples used in this study. Our findings may inform methods of Xuan paper production, selection of Xuan paper for conservation purposes, as well as preventive conservation of Xuan paper-based artefacts.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3cc2a2a32d0556397286bedf5ad85e07" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490829,"asset_id":113563020,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490829/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563020"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563020"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563020;

The degradation rate constants of untreated and deacidified paper samples after accelerated thermal degradation were calculated based on weight average molecular mass determination to evaluate the lifetime extension of paper. The efficiency factors determined after accelerated thermal degradation of untreated and treated paper showed that paper lifetime prolongation after Bookkeeper deacidification treatment is highly limited for most of the investigated paper samples.

Although the mechanism and the rate of degradation have been studied extensively for historic papers, it seems that less attention has been given to real contemporary papers so far. Currently, the main structural component of modern paper is a felt of cellulose fibres from different origins (e.g., hardwood, softwood, grass, bast, recycled fibres), with the addition of other compounds (sizing, fillers etc.). Due to environmental issues, there has been a significant increase of recycled paper as fibrous component of print paper over the last years. Our research is mainly focused on the degradation of contemporary paper obtained by accelerated ageing experiments, exposing the samples to extreme conditions in terms of temperature (T) and relative humidity (RH), in order to develop a dose-response function. The samples studied in this research consist of two kinds of contemporary papers, substantially different from each other: pure cellulose papers that meet the ISO9706 standard specifications, and recycled papers with different percentages of recycled materials. Along with the determination of the fibre components of the papers by fibre furnish analysis and the detection of lignin by phloroglucinol tests, the degradation of the paper samples during the ageing tests are analysed in terms of pH, measured with the cold extraction method, and degree of polymerisation (DP), determined by viscometry in cupriethylenediamine solvent. These data allow to evaluate the extent of degradation of contemporary papers through a dose-response function. The elaboration of these results will lead to a comparison with the dose-response functions already modelled and/or to new dose-response function for contemporary papers</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563016"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563016"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563016;

Due to the insolubility of papers with high lignin content in cupriethylenediamine (CED), such as groundwood papers, viscometric determination is not possible; therefore, pretreatment is required to allow subsequent dissolution of the papers. In this study, the pretreatment of historical papers containing groundwood with sodium chlorite in acetic acid was investigated, which enables dissolution of the paper samples in CED and determination of the cellulose average degree of polymerization by viscometry (DPv). Kappa number was determined to estimate the lignin content in the papers.

Die Farboberfläche ist bröckelig und blättert ab, der Träger ist empfindlich gegenüber Feuchteeintrag sowie faltig und an bestimmten Stellen abgerissen.

In this investigation the adsorption of aspartic acid (Asp) and lysine (Lys) onto SPIONs was studied, based on a characterization of the suspension properties, i.e., measurements of the ξ-potential, the hydrodynamic size, and the osmolality, and by direct HPLC analysis of the AA in the supernatants and at the nanoparticles of the ultracentrifuged suspensions. The results show that the AAs adsorb onto the SPIONs in the form of large molecular associates, which decisively influence the nanoparticles’ surface properties. A measurement of the freezing-point depression using a Knauer osmometer proved that the molecular associates are already formed in the AA aqueous solutions.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="116368119"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="116368119"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 116368119; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=116368119]").text(description); $(".js-view-count[data-work-id=116368119]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 116368119; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='116368119']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-a9bf3a2bc8c89fa2a77156577594264ee8a0f214d74241bc0fcd3f69f8d107ac.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (false){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "-1" } } $('.js-work-strip[data-work-id=116368119]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":116368119,"title":"Adsorption of Amino Acids, Aspartic Acid, and Lysine onto Iron-Oxide Nanoparticles","internal_url":"https://www.academia.edu/116368119/Adsorption_of_Amino_Acids_Aspartic_Acid_and_Lysine_onto_Iron_Oxide_Nanoparticles","owner_id":277533442,"coauthors_can_edit":true,"owner":{"id":277533442,"first_name":"Irena","middle_initials":null,"last_name":"Kralj Cigic","page_name":"IrenaKraljCigic","domain_name":"uni-lj","created_at":"2023-07-20T03:21:31.212-07:00","display_name":"Irena Kralj Cigic","url":"https://uni-lj.academia.edu/IrenaKraljCigic"},"attachments":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> <div class="js-work-strip profile--work_container" data-work-id="116368114"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/116368114/Accumulation_and_Transformation_of_Biogenic_Amines_and_Gamma_Aminobutyric_Acid_GABA_in_Chickpea_Sourdough"><img alt="Research paper thumbnail of Accumulation and Transformation of Biogenic Amines and Gamma-Aminobutyric Acid (GABA) in Chickpea Sourdough" class="work-thumbnail" src="https://attachments.academia-assets.com/112518380/thumbnails/1.jpg" /></a></div><div class="wp-workCard wp-workCard_itemContainer"><div class="wp-workCard_item wp-workCard--title"><a class="js-work-strip-work-link text-gray-darker" data-click-track="profile-work-strip-title" href="https://www.academia.edu/116368114/Accumulation_and_Transformation_of_Biogenic_Amines_and_Gamma_Aminobutyric_Acid_GABA_in_Chickpea_Sourdough">Accumulation and Transformation of Biogenic Amines and Gamma-Aminobutyric Acid (GABA) in Chickpea Sourdough</a></div><div class="wp-workCard_item"><span>Foods</span><span>, 2021</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In general, sourdough fermentation leads to an improvement in the technological, nutritional, and...</span><a class="js-work-more-abstract" data-broccoli-component="work_strip.more_abstract" data-click-track="profile-work-strip-more-abstract" href="javascript:;"><span> more </span><span><i class="fa fa-caret-down"></i></span></a><span class="js-work-more-abstract-untruncated hidden">In general, sourdough fermentation leads to an improvement in the technological, nutritional, and sensory properties of bakery products. The use of non-conventional flours with a specific autochthonous microbiota may lead to the formation of secondary metabolites, which may even have undesirable physiological and toxicological effects. Chickpea flours from different suppliers have been used to produce sourdoughs by spontaneous and inoculated fermentations. The content of nutritionally undesirable biogenic amines (BA) and beneficial gamma-aminobutyric acid (GABA) was determined by chromatography. Fenugreek sprouts, which are a rich source of amine oxidases, were used to reduce the BA content in the sourdoughs.

In this work, we examine the potentials of mid-and near-infrared spectroscopy, however, in order to fully utilise the selectivity inherent to spectroscopic multivariate measurements, genetic algorithms were used to select spectral data derived from information-rich FT-IR or UV-VIS-NIR measurements to build multivariate calibration models based on partial least squares regression, relating spectra to gelatine content in paper. A selective but laborious chromatographic method for the quantification of hydroxyproline (HYP) has been developed to provide the reference data on gelatine content. We used 9-fluorenylmethyl chloroformate (FMOC) to derivatise HYP, which was subsequently determined using reverse-phase liquid chromatographic separation and fluorimetric detection. In this process, the sample is consumed, which is why the method can only be used as a reference method. The sampling flexibility afforded by small-size field-portable spectroscopic instrumentation combined Published in Talanta 82 (2010) 1784-1790 2 with chemometric data analysis, represents an attractive addition to existing analytical techniques for cultural heritage materials.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="25712225814413350388ad91d9988ab4" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490834,"asset_id":113563027,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490834/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563027"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563027"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563027;

The weight average molar mass was determined for a collection of 57 samples, ranging from 75 to 186 kg/mol with a median of 102 kg/mol. Rigid PVC objects were found to have a significantly lower weight average molar mass (M w = 81 kg/mol) than plasticized ones (M w = 102 kg/mol). Thin objects also exhibited significantly lower M w than bulky objects. A substantial presence of aggregates was noted and characterized as an 'aggregate ratio' for the entire collection. Heating a solution of poly(vinyl chloride) in THF at 55 °C for 5 h proved successful in the dissociation of the aggregates and allowed for an accurate determination of molar mass. The uncertainty of the M w determination was statistically evaluated and used to study the effects of accelerated degradation on M w. No statistically significant changes in M w were observed in samples artificially aged at 50 °C to 80 °C for up to 15 weeks, indicating that M w does not decrease during degradation of a PVC heritage object and that accelerated degradation does not lead to polymer crosslinking.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="b5950302713ed0671749073cc39299da" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490874,"asset_id":113563026,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490874/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563026"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563026"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563026;

For the first time, a large and diverse collection of more than 100 PVC objects in different degradation stages and of diverse chemical compositions was analysed by chromatographic and spectroscopic techniques to create a dataset used to construct classification and regression models. Accounting for this variety makes the model more robust and reliable for the analysis of objects in museum collections. Six different machine learning classification algorithms were compared to determine the algorithm with the highest classification accuracy of the most common plasticizers, based solely on the spectroscopic data. A classification model capable of the identification of di(2-ethylhexyl) phthalate, di(2-ethylhexyl) terephthalate, diisononyl phthalate, diisodecyl phthalate, a mixture of diisononyl phthalate and diisodecyl phthalate, and unplasticized PVC was constructed. Additionally, regression models for quantification of di(2-ethylhexyl) phthalate and di(2-ethylhexyl) terephthalate in PVC were built. This study of real-life objects demonstrates that classification and quantification of plasticizers in a general collection of degraded PVC objects is possible, providing valuable data to collection managers. Poly(vinyl chloride) (PVC) is a modern polymeric material and one of the most widely used plastics today 1. Since its commercialization, it has been used in a variety of applications, including clothing, toys, tubing and piping, flooring, and medical devices 2,3. Plasticizers are used to improve and adjust the mechanical properties of the material by increasing flexibility, reducing viscosity, and decreasing friction during manufacture. Plasticizers can account for up to 50% of the total mass of PVC objects 4-6. Because of its versatility PVC has also been used as a material for artworks 4,7,8 and represents a significant part of modern and contemporary collections 9. The challenges of preserving PVC are well recognised in the literature 10-12 , and some are related to the plasticizers in the material 13. There are reported cases of plasticizer accumulating on the surface, which can trap dust and dirt, as well as plasticizer loss, which can cause warping, cracking, and structural failure 7,13-15. Phthalates, terephthalates, adipates, trimellitates, and citrates represent the majority of commercially-used plasticizers. Dibutyl phthalate (DBP), diisobutyl phthalate (DIBP), di(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DINP), diisodecyl phthalate (DIDP), di(2-ethylhexyl) terephthalate (DOTP), di(2-propylheptyl) phthalate (DPHP), and diisononyl cyclohexane-1,2-dicarboxylate (DINCH) were found as the most interesting plasticizers based on their properties, historic significance and market popularity (Supplementary Fig. S1). Market popularity has shifted over the decades mainly due to legislation changes in Europe and the USA. DBP and DIBP are short-chain phthalate plasticizers that have been primarily used in combination with DEHP and DINP 16. DBP is a suspected endocrine disruptor, so its usage is regulated and restricted for use in toys in the EU 17. DEHP had been used as a general-purpose plasticizer for all consumer products, including toys, food contact material, cosmetics, medical devices and household products. In 2008, it was classified as hazardous in Europe 18 and the USA, and was replaced by higher molecular weight phthalates (DINP and DIDP) as general-purpose plasticizers. DOTP is a terephthalate isomer of DEHP, with similar plasticization abilities, but is subject to less regulatory restrictions</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="903d1be026b49b07e13d825c4fc50048" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490833,"asset_id":113563025,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490833/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563025"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563025"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563025;

A novel theoretical model using Hansen solubility parameters as the basis for a complete mathematical derivation of the model was developed. The theoretical model also includes the cavitation volumes of the analytes, which were calculated using ab initio density functional theory methods. A set of three homologous phthalates was used for experimental data collection and subsequent model construction. The training error and the generalization error of the model were additionally evaluated using a range of chemically diverse analytes. Statistical evaluation of the results revealed that the model is suitable for analyte retention prediction but is limited to the analytes used in the model construction. Therefore, the resulting theoretical model cannot be easily generalized. A retention anomaly attributed to the column temperature and mobile phase composition was experimentally observed and mathematically investigated.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5c23e9c05869aa8acde9b80f295cb7f6" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490836,"asset_id":113563024,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490836/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563024"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563024"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563024;

Due to their poor biodegradability of these contaminants in municipal wastewater treatment plants, additional advanced oxidation processes such as electrochemical treatments have been developed to improve the standard biological treatment. Here we review the applications of electrochemical treatments of wastewater for the removal of the following plastic contaminants: bisphenol A, phthalic acid esters, and benzotriazoles. We present the effectiveness of treatment in terms of contaminant removal and mineralization; the identification of transformation products; toxicity assessment; and process energy requirements. In the present review, we have focused on the applications of electrochemical treatments of wastewater for the removal of three important groups of contaminants originating mainly from plastics: bisphenol A, phthalic acid esters, and benzotriazoles. The review focuses on the research of electrochemical treatments for these contaminants from the last five years. The papers are assessed from the point of i) effectiveness of treatment in terms of contaminant removal and mineralization; ii) identification of transformation products; iii) toxicity assessment; iv) processes' energy requirements. Electrochemical treatments were confirmed to be a viable option for the removal of selected contaminants from wastewater.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="94ee195f544426fdb134152d49bc0566" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490830,"asset_id":113563023,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490830/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563023"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563023"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563023;

In this research, a selection of contemporary unsized Xuan papers was investigated, representing diverse raw materials. Seven out of twelve contemporary unsized Xuan papers were determined to be approximately neutral and contain[2% alkaline reserve, indicating good durability. Viscometry was used to determine the degree of polymerisation (DP) as none of the samples gave significant reactions to the phloroglucinol spot test. The average DP of ten contemporary unsized Xuan papers is~1700, excluding two papers that have presumably been sun-bleached, and that exhibit significantly lower DP. Using X-ray fluorescence, it can be demonstrated that Ca and Si are the dominant elements and interestingly, Ca content is directly correlated with ash content and with alkaline reserve. Accelerated degradation was performed at two sets of environmental conditions, i.e. 90°C, 30% RH and 60°C, 70% RH, and the established degradation rates agreed with the Collections Demography model of paper degradation meaning that degradation of Xuan papers proceeds in the same way as other types of paper. This research gives fundamental insights into contemporary unsized Xuan papers, which exhibit good stability during accelerated degradation despite the low starting DP in the context of the samples used in this study. Our findings may inform methods of Xuan paper production, selection of Xuan paper for conservation purposes, as well as preventive conservation of Xuan paper-based artefacts.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="3cc2a2a32d0556397286bedf5ad85e07" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":110490829,"asset_id":113563020,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/110490829/download_file?s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563020"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563020"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563020;

The degradation rate constants of untreated and deacidified paper samples after accelerated thermal degradation were calculated based on weight average molecular mass determination to evaluate the lifetime extension of paper.

Although the mechanism and the rate of degradation have been studied extensively for historic papers, it seems that less attention has been given to real contemporary papers so far. Currently, the main structural component of modern paper is a felt of cellulose fibres from different origins (e.g., hardwood, softwood, grass, bast, recycled fibres), with the addition of other compounds (sizing, fillers etc.). Due to environmental issues, there has been a significant increase of recycled paper as fibrous component of print paper over the last years. Our research is mainly focused on the degradation of contemporary paper obtained by accelerated ageing experiments, exposing the samples to extreme conditions in terms of temperature (T) and relative humidity (RH), in order to develop a dose-response function. The samples studied in this research consist of two kinds of contemporary papers, substantially different from each other: pure cellulose papers that meet the ISO9706 standard specifications, and recycled papers with different percentages of recycled materials. Along with the determination of the fibre components of the papers by fibre furnish analysis and the detection of lignin by phloroglucinol tests, the degradation of the paper samples during the ageing tests are analysed in terms of pH, measured with the cold extraction method, and degree of polymerisation (DP), determined by viscometry in cupriethylenediamine solvent. These data allow to evaluate the extent of degradation of contemporary papers through a dose-response function. The elaboration of these results will lead to a comparison with the dose-response functions already modelled and/or to new dose-response function for contemporary papers</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="113563016"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="113563016"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 113563016;

Due to the insolubility of papers with high lignin content in cupriethylenediamine (CED), such as groundwood papers, viscometric determination is not possible; therefore, pretreatment is required to allow subsequent dissolution of the papers. In this study, the pretreatment of historical papers containing groundwood with sodium chlorite in acetic acid was investigated, which enables dissolution of the paper samples in CED and determination of the cellulose average degree of polymerization by viscometry (DPv). Kappa number was determined to estimate the lignin content in the papers.
