The paper presents a study regarding colour and colouring properties of the natural, non � toxic dye extracted from fresh fruits of cranberry (Vaccinium vitis-idaea) water extracted.

The adsorbent surface characteristics were investigated using SEM and FTIR analysis. For maximum removal efficiency, several parameters that influence the dye adsorption were optimized using the Taguchi method. Equilibrium and kinetic modeling, along with thermodynamic studies, were conducted to elucidate the adsorption mechanism. Taguchi experimental design showed that the factor with the highest influence was the adsorbent dose, with a percent contribution established by the ANOVA analysis of 40.89%. Langmuir isotherm and pseudo-second order kinetic model characterizes the adsorption process. The maximum adsorption capacity, 121.16 (mg g−1), is higher than other similar adsorbents presented in scientific literature.

This mode of copolymerization keeps an inert atmosphere throughout the entire reaction and contributes to proper mixing of the monomers. Higher pressure of the bubbling ensures the faster contact of the species, and a higher conversion was obtained in a shorter reaction time. The conversion of monomer at 124 Pa after 210 min is total, which is particularly noteworthy due to the absence of residual monomer that represents hazardous compounds, with negative impact upon employees and end-user safety. Higher conversions are obtained at 96 °C, 124 Pa nitrogen bubble pressure, 60/40% moles monomer ratio BA/MMA and 2% POB. The molar mass Mw, Mn and PDI decrease with the increase in temperature quite linearly. In the absence of nitrogen bubbling, the copolymer composition is approximately the same as in the feeding mixture. The corrosion protection efficiency of steel painted with these acrylic coatings was carried out by means of OCP and potentiodynamic polarization testing and electrochemical impedance spectroscopy (EIS).</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="80521076"><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="80521076"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521076;

The synthesized dye contains 4,4′-diaminostilbene-2,2′-disulfonic acid, as middle component and 2,7-dihydroxynaphthalene, as coupling component. It was analyzed by thin-layer chromatography (TLC), FT/IR, UV/VIS, 1H NMR, 13C NMR spectroscopy, and HRMS spectrometry. The molecular dye structure was investigated using molecular mechanics and the Density Functional Theory (DFT) approach at the B3LYP/6-31G(d,p), B3LYP/6-31+G(d,p) and B3PW91/6-311G(d,p) levels. Theoretical vibrational frequencies and structural parameters were calculated and the dye UV/VIS spectrum was simulated using the CIS, TD and ZINDO methods and compared with the experimental data. The ZINDO approach gave better maximum absorption predicted values compared to the CIS and TD methods. A generally good agreement between the experimental and theoretical computed absorption maxima and excellent correspondences between the experimental and calculated vibrational frequencies and chemical shifts were found. The experimental and simulated vibrational, UV/VIS and 13C NMR spectra confirmed the trans-configuration form of the π-bonds of the investigated dye. The CIEL∗a∗b∗ color space was used in all color measurements for the dye in powder and its mixtures with a water-based acrylic resin and confirmed the color properties of the newly synthesized dye.</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="80521073"><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="80521073"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521073; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=80521073]").text(description); $(".js-view-count[data-work-id=80521073]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 80521073; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='80521073']"); 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" } } $('.js-work-strip[data-work-id=80521073]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":80521073,"title":"Synthesis, spectral characterization, and theoretical investigations of a new azo-stilbene dye for acrylic resins","internal_url":"https://www.academia.edu/80521073/Synthesis_spectral_characterization_and_theoretical_investigations_of_a_new_azo_stilbene_dye_for_acrylic_resins","owner_id":14672940,"coauthors_can_edit":true,"owner":{"id":14672940,"first_name":"simona","middle_initials":"","last_name":"popa","page_name":"spopa","domain_name":"upt","created_at":"2014-08-03T22:21:34.326-07:00","display_name":"simona popa","url":"https://upt.academia.edu/spopa","email":"QnhjVERTS0dKY1MrZGpsL2hGTGVtOGJUNDBRVGRvbGdvMTE5b2c4cXlLQT0tLVQ5djFoeHhrSDI3YTU4OUhsTzk5SGc9PQ==--c58462938f13fff019ecd69578a3eae61a8193d8"},"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="80521071"><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/80521071/Collagen_Films_Obtained_from_Collagen_Solutions_Characterized_by_Rheology"><img alt="Research paper thumbnail of Collagen Films Obtained from Collagen Solutions Characterized by Rheology" class="work-thumbnail" src="https://attachments.academia-assets.com/86875154/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/80521071/Collagen_Films_Obtained_from_Collagen_Solutions_Characterized_by_Rheology">Collagen Films Obtained from Collagen Solutions Characterized by Rheology</a></div><div class="wp-workCard_item"><span>Materiale Plastice</span><span>, 2017</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Collagen is an important natural biopolymer, found in mammal s body.

Its importance increased in last decades. Collagen has many applications in medicine and cosmetics. The work presented in this paper shows one method to obtain collagen films from collagen solutions. These collagen solutions were characterized by rheological measurements. The preparation of the collagen films was performed in the presence of calcium and silicium salts, using glycerin as plasticizer. The collagen was first solubilized and reconstituted, in order to maintain its initial properties.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ae26d068a449ee8df51721b28bee0371" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":86875154,"asset_id":80521071,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/86875154/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="80521071"><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="80521071"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521071;

RESULTS: The influence of the main process variables: pH, adsorbent dose and contact time was investigated for optimal manganese ions adsorption. The highest adsorption efficiency of the wood ash (more than 98%) was recorded at pH 6, adsorbent dose of 10 g L⁻¹ and contact time 15 min. The ion adsorption process is best described by Langmuir isotherm and pseudo second‐order kinetic model. Maximum adsorption capacity, 54.94 mg g⁻¹, is better than other adsorbent materials previously used for manganese adsorption. The exhausted wood ash, resulted after the manganese adsorption was used as soil amendment for barley crop, Hordeum vulgare L. The beneficial effect upon the studied plants was highlighted using the specific parameters: germination percent (up to 10% higher), plant average length (higher by 14–35%), biomass (up to 200%) and relative growth rate (higher by 6–12%) compared to those obtained for the control sample. CONCLUSION: These results show that all the wastes involved have been used successfully and support the proposed eco‐friendly technical solution for some industrial wastes management. © 2020 Society of Chemical Industry</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="80521067"><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="80521067"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521067; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=80521067]").text(description); $(".js-view-count[data-work-id=80521067]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 80521067; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='80521067']"); 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" } } $('.js-work-strip[data-work-id=80521067]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":80521067,"title":"A green approach for treatment of wastewater with manganese using wood ash","internal_url":"https://www.academia.edu/80521067/A_green_approach_for_treatment_of_wastewater_with_manganese_using_wood_ash","owner_id":14672940,"coauthors_can_edit":true,"owner":{"id":14672940,"first_name":"simona","middle_initials":"","last_name":"popa","page_name":"spopa","domain_name":"upt","created_at":"2014-08-03T22:21:34.326-07:00","display_name":"simona popa","url":"https://upt.academia.edu/spopa","email":"MWxRZnJFNTRPR0NGNHRRaGU4aDhsWVphL0J3elUwaHdCVEpaS3BJYkg1OD0tLXhJT3hDaGtUcExyeGszOFJEeE9zTFE9PQ==--f82d9619c8889f7e90e5f6010102a87bc292609f"},"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="80521065"><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/80521065/Heat_transfer_influence_on_fractionation_in_flooded_packed_columns"><img alt="Research paper thumbnail of Heat transfer influence on fractionation in flooded packed columns" class="work-thumbnail" src="https://attachments.academia-assets.com/86875187/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/80521065/Heat_transfer_influence_on_fractionation_in_flooded_packed_columns">Heat transfer influence on fractionation in flooded packed columns</a></div><div class="wp-workCard_item"><span>Studia Universitatis Babeș-Bolyai Chemia</span><span>, 2019</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In packed fractionation, the liquid phase can be forced to become continuous, and the vapor phase...</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 packed fractionation, the liquid phase can be forced to become continuous, and the vapor phase dispersed, realizing emulsification regime.

The yield of polyaniline (PANI) was about 60?69 %. The polymerization process required an induction time 8?10 times greater than in other acids (hydrochloric, sulfuric). The average density of the obtained polymer was 1.395 g cm-3 for PANI-salt and 1.203 g cm-3 for PANI-base. The acid capacity of PANI depends on the synthesis parameters and the maximum value was 15.02 meq/g polymer. The inherent viscosity of PANI was 0.662 dl/g at aniline/oxidant molar ratios &gt;2 and 0 ?C. The oxidation state was a function of the synthesis parameters and lay between 0.553?0.625, as determined from UV-VIS and titration with TiCl3 data. The PANI samples were characterized by measurements of their density, inherent viscosity conductivity, acid capacity, FTIR and UV-VIS spectrum, and thermogravimetric data.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5327f83c45c8b5aa2d9641feac4b4fdc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":86875188,"asset_id":80521062,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/86875188/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="80521062"><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="80521062"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521062;

The influence of pH, contact time, adsorbent dose, initial dye concentration, temperature and ionic strength on the adsorption process were followed. Equilibrium, kinetic, and thermodynamic studies were conducted in order to understand the adsorption process mechanism. Process optimization was performed using the Taguchi method. Sips isotherm and general order kinetic model characterize the adsorption process. The maximum adsorption capacity, 200.4 (mg g−1), was better compared with other similar bioadsorbents. Thermodynamic parameters indicated that the adsorption process is spontaneous, favorable and endothermic and also that physisorption is involved in the process.

In this context, this paper proposes a new alternative to obtain glass fertilizers (agriglasses) by reusing two cheap and easily available wastes, wood ash and manganese rich sludge resulting from drinking water treatment processes for groundwater sources. Glasses were obtained using different amounts of wastes together with (NH4)2HPO4 and K2CO3 as raw materials. The P-K-Mn nutrient solubilization from the obtained glasses was investigated using a citric acid solution. The kinetics of the leaching process was studied after 1, 7, 14, 21 and 28 days, respectively. The intraparticle diffusion model was used to interpret kinetic data. Two distinct stages of the ion leaching process were recorded for all of the studied compositions: first through intraparticle diffusion (the rate-controlling stage) and second through diffusion through the particle–medium interface.

The esterification process, which take place in a column type reactor is very complex due to the intergrowth of two types of factors: those which usually influence esterification process in general and those which are specific for the chosen process. The inner stirring may be achieved by different mechanical means or by bubbling a gas. This study presents some factors that influence the esterification in a bubble gas column reactor: the size of the gas bubbles, packing material, jacket temperature. The process performed in this reactor is energetic efficient and the outer gas contains only a very few amount of volatiles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="acb3f1e1ab7107f46f6addf5a3223aca" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":78801561,"asset_id":68263363,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/78801561/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="68263363"><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="68263363"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 68263363;

Equilibrium, kinetic, and thermodynamic studies were performed in order to understand the adsorption process. Taguchi method and ANOVA test were used to optimize the dye adsorption conditions and to establish the percentage contribution of each factor, respectively. The accuracy of the Taguchi prediction method was analyzed by correlating the predicted dye removal efficiency with the experimentally determined one.

The adsorbent surface was examined using SEM and FTIR techniques. The experiments were conducted, in batch system, to find out the effect of pH, contact time, adsorbent dose, initial dye concentration, temperature and ionic strength on dye adsorption. The process is best described by Langmuir isotherm and the pseudo second order kinetic model. Maximum adsorption capacity, 188.2 (mg g−1), is better than other similar adsorbent materials. Thermodynamic parameters revealed a spontaneous and endothermic process, suggesting a physisorption mechanism. A Taguchi orthogonal array (L27) experimental design was used to determine the optimum conditions for the removal of dye. Various desorbing agents were used to investigate the regeneration possibility of used adsorbent.

The structure of the ligand and the structure of the new synthesized copper complex were elucidated by all the above mentioned analysis methods. The formation of the azo metal complex with Cu(II) was confirmed by UV-Vis spectrum. Thermogravimetric and spectral analysis reveal its different stability in the air and nitrogen atmosphere, with high nitrogen stability. The PXRD analysis shows crystalline structure for the copper complex. At the same time, the color analysis was performed for the ligand and the synthesized complex in powder by means of UV-Vis CIEL*a*b* color space parameters, under the CIE recommended illumi...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d2b2a72d5e6f170fa5b521ca057dd712" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":78801549,"asset_id":68263348,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/78801549/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="68263348"><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="68263348"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 68263348;

The adsorbent surface characteristics were investigated using SEM and FTIR analysis. For maximum removal efficiency, several parameters that influence the dye adsorption were optimized using the Taguchi method. Equilibrium and kinetic modeling, along with thermodynamic studies, were conducted to elucidate the adsorption mechanism. Taguchi experimental design showed that the factor with the highest influence was the adsorbent dose, with a percent contribution established by the ANOVA analysis of 40.89%. Langmuir isotherm and pseudo-second order kinetic model characterizes the adsorption process. The maximum adsorption capacity, 121.16 (mg g−1), is higher than other similar adsorbents presented in scientific literature.

This mode of copolymerization keeps an inert atmosphere throughout the entire reaction and contributes to proper mixing of the monomers. Higher pressure of the bubbling ensures the faster contact of the species, and a higher conversion was obtained in a shorter reaction time. The conversion of monomer at 124 Pa after 210 min is total, which is particularly noteworthy due to the absence of residual monomer that represents hazardous compounds, with negative impact upon employees and end-user safety. Higher conversions are obtained at 96 °C, 124 Pa nitrogen bubble pressure, 60/40% moles monomer ratio BA/MMA and 2% POB. The molar mass Mw, Mn and PDI decrease with the increase in temperature quite linearly. In the absence of nitrogen bubbling, the copolymer composition is approximately the same as in the feeding mixture. The corrosion protection efficiency of steel painted with these acrylic coatings was carried out by means of OCP and potentiodynamic polarization testing and electrochemical impedance spectroscopy (EIS).</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="80521076"><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="80521076"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521076;

The synthesized dye contains 4,4′-diaminostilbene-2,2′-disulfonic acid, as middle component and 2,7-dihydroxynaphthalene, as coupling component. It was analyzed by thin-layer chromatography (TLC), FT/IR, UV/VIS, 1H NMR, 13C NMR spectroscopy, and HRMS spectrometry. The molecular dye structure was investigated using molecular mechanics and the Density Functional Theory (DFT) approach at the B3LYP/6-31G(d,p), B3LYP/6-31+G(d,p) and B3PW91/6-311G(d,p) levels. Theoretical vibrational frequencies and structural parameters were calculated and the dye UV/VIS spectrum was simulated using the CIS, TD and ZINDO methods and compared with the experimental data. The ZINDO approach gave better maximum absorption predicted values compared to the CIS and TD methods. A generally good agreement between the experimental and theoretical computed absorption maxima and excellent correspondences between the experimental and calculated vibrational frequencies and chemical shifts were found. The experimental and simulated vibrational, UV/VIS and 13C NMR spectra confirmed the trans-configuration form of the π-bonds of the investigated dye. The CIEL∗a∗b∗ color space was used in all color measurements for the dye in powder and its mixtures with a water-based acrylic resin and confirmed the color properties of the newly synthesized dye.</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="80521073"><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="80521073"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521073; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=80521073]").text(description); $(".js-view-count[data-work-id=80521073]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 80521073; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='80521073']"); 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" } } $('.js-work-strip[data-work-id=80521073]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":80521073,"title":"Synthesis, spectral characterization, and theoretical investigations of a new azo-stilbene dye for acrylic resins","internal_url":"https://www.academia.edu/80521073/Synthesis_spectral_characterization_and_theoretical_investigations_of_a_new_azo_stilbene_dye_for_acrylic_resins","owner_id":14672940,"coauthors_can_edit":true,"owner":{"id":14672940,"first_name":"simona","middle_initials":"","last_name":"popa","page_name":"spopa","domain_name":"upt","created_at":"2014-08-03T22:21:34.326-07:00","display_name":"simona popa","url":"https://upt.academia.edu/spopa","email":"QnhjVERTS0dKY1MrZGpsL2hGTGVtOGJUNDBRVGRvbGdvMTE5b2c4cXlLQT0tLVQ5djFoeHhrSDI3YTU4OUhsTzk5SGc9PQ==--c58462938f13fff019ecd69578a3eae61a8193d8"},"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="80521071"><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/80521071/Collagen_Films_Obtained_from_Collagen_Solutions_Characterized_by_Rheology"><img alt="Research paper thumbnail of Collagen Films Obtained from Collagen Solutions Characterized by Rheology" class="work-thumbnail" src="https://attachments.academia-assets.com/86875154/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/80521071/Collagen_Films_Obtained_from_Collagen_Solutions_Characterized_by_Rheology">Collagen Films Obtained from Collagen Solutions Characterized by Rheology</a></div><div class="wp-workCard_item"><span>Materiale Plastice</span><span>, 2017</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">Collagen is an important natural biopolymer, found in mammal s body.

Its importance increased in last decades. Collagen has many applications in medicine and cosmetics. The work presented in this paper shows one method to obtain collagen films from collagen solutions. These collagen solutions were characterized by rheological measurements. The preparation of the collagen films was performed in the presence of calcium and silicium salts, using glycerin as plasticizer. The collagen was first solubilized and reconstituted, in order to maintain its initial properties.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="ae26d068a449ee8df51721b28bee0371" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":86875154,"asset_id":80521071,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/86875154/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="80521071"><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="80521071"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521071;

RESULTS: The influence of the main process variables: pH, adsorbent dose and contact time was investigated for optimal manganese ions adsorption. The highest adsorption efficiency of the wood ash (more than 98%) was recorded at pH 6, adsorbent dose of 10 g L⁻¹ and contact time 15 min. The ion adsorption process is best described by Langmuir isotherm and pseudo second‐order kinetic model. Maximum adsorption capacity, 54.94 mg g⁻¹, is better than other adsorbent materials previously used for manganese adsorption. The exhausted wood ash, resulted after the manganese adsorption was used as soil amendment for barley crop, Hordeum vulgare L. The beneficial effect upon the studied plants was highlighted using the specific parameters: germination percent (up to 10% higher), plant average length (higher by 14–35%), biomass (up to 200%) and relative growth rate (higher by 6–12%) compared to those obtained for the control sample. CONCLUSION: These results show that all the wastes involved have been used successfully and support the proposed eco‐friendly technical solution for some industrial wastes management. © 2020 Society of Chemical Industry</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="80521067"><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="80521067"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521067; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=80521067]").text(description); $(".js-view-count[data-work-id=80521067]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 80521067; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='80521067']"); 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" } } $('.js-work-strip[data-work-id=80521067]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":80521067,"title":"A green approach for treatment of wastewater with manganese using wood ash","internal_url":"https://www.academia.edu/80521067/A_green_approach_for_treatment_of_wastewater_with_manganese_using_wood_ash","owner_id":14672940,"coauthors_can_edit":true,"owner":{"id":14672940,"first_name":"simona","middle_initials":"","last_name":"popa","page_name":"spopa","domain_name":"upt","created_at":"2014-08-03T22:21:34.326-07:00","display_name":"simona popa","url":"https://upt.academia.edu/spopa","email":"MWxRZnJFNTRPR0NGNHRRaGU4aDhsWVphL0J3elUwaHdCVEpaS3BJYkg1OD0tLXhJT3hDaGtUcExyeGszOFJEeE9zTFE9PQ==--f82d9619c8889f7e90e5f6010102a87bc292609f"},"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="80521065"><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/80521065/Heat_transfer_influence_on_fractionation_in_flooded_packed_columns"><img alt="Research paper thumbnail of Heat transfer influence on fractionation in flooded packed columns" class="work-thumbnail" src="https://attachments.academia-assets.com/86875187/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/80521065/Heat_transfer_influence_on_fractionation_in_flooded_packed_columns">Heat transfer influence on fractionation in flooded packed columns</a></div><div class="wp-workCard_item"><span>Studia Universitatis Babeș-Bolyai Chemia</span><span>, 2019</span></div><div class="wp-workCard_item"><span class="js-work-more-abstract-truncated">In packed fractionation, the liquid phase can be forced to become continuous, and the vapor phase...</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 packed fractionation, the liquid phase can be forced to become continuous, and the vapor phase dispersed, realizing emulsification regime.

The yield of polyaniline (PANI) was about 60?69 %. The polymerization process required an induction time 8?10 times greater than in other acids (hydrochloric, sulfuric). The average density of the obtained polymer was 1.395 g cm-3 for PANI-salt and 1.203 g cm-3 for PANI-base. The acid capacity of PANI depends on the synthesis parameters and the maximum value was 15.02 meq/g polymer. The inherent viscosity of PANI was 0.662 dl/g at aniline/oxidant molar ratios &gt;2 and 0 ?C. The oxidation state was a function of the synthesis parameters and lay between 0.553?0.625, as determined from UV-VIS and titration with TiCl3 data. The PANI samples were characterized by measurements of their density, inherent viscosity conductivity, acid capacity, FTIR and UV-VIS spectrum, and thermogravimetric data.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5327f83c45c8b5aa2d9641feac4b4fdc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":86875188,"asset_id":80521062,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/86875188/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="80521062"><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="80521062"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 80521062;

The influence of pH, contact time, adsorbent dose, initial dye concentration, temperature and ionic strength on the adsorption process were followed. Equilibrium, kinetic, and thermodynamic studies were conducted in order to understand the adsorption process mechanism. Process optimization was performed using the Taguchi method. Sips isotherm and general order kinetic model characterize the adsorption process. The maximum adsorption capacity, 200.4 (mg g−1), was better compared with other similar bioadsorbents. Thermodynamic parameters indicated that the adsorption process is spontaneous, favorable and endothermic and also that physisorption is involved in the process.

In this context, this paper proposes a new alternative to obtain glass fertilizers (agriglasses) by reusing two cheap and easily available wastes, wood ash and manganese rich sludge resulting from drinking water treatment processes for groundwater sources. Glasses were obtained using different amounts of wastes together with (NH4)2HPO4 and K2CO3 as raw materials. The P-K-Mn nutrient solubilization from the obtained glasses was investigated using a citric acid solution. The kinetics of the leaching process was studied after 1, 7, 14, 21 and 28 days, respectively. The intraparticle diffusion model was used to interpret kinetic data. Two distinct stages of the ion leaching process were recorded for all of the studied compositions: first through intraparticle diffusion (the rate-controlling stage) and second through diffusion through the particle–medium interface.

The esterification process, which take place in a column type reactor is very complex due to the intergrowth of two types of factors: those which usually influence esterification process in general and those which are specific for the chosen process. The inner stirring may be achieved by different mechanical means or by bubbling a gas. This study presents some factors that influence the esterification in a bubble gas column reactor: the size of the gas bubbles, packing material, jacket temperature. The process performed in this reactor is energetic efficient and the outer gas contains only a very few amount of volatiles.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="acb3f1e1ab7107f46f6addf5a3223aca" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":78801561,"asset_id":68263363,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/78801561/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="68263363"><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="68263363"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 68263363;

Equilibrium, kinetic, and thermodynamic studies were performed in order to understand the adsorption process. Taguchi method and ANOVA test were used to optimize the dye adsorption conditions and to establish the percentage contribution of each factor, respectively. The accuracy of the Taguchi prediction method was analyzed by correlating the predicted dye removal efficiency with the experimentally determined one.

The adsorbent surface was examined using SEM and FTIR techniques. The experiments were conducted, in batch system, to find out the effect of pH, contact time, adsorbent dose, initial dye concentration, temperature and ionic strength on dye adsorption. The process is best described by Langmuir isotherm and the pseudo second order kinetic model. Maximum adsorption capacity, 188.2 (mg g−1), is better than other similar adsorbent materials. Thermodynamic parameters revealed a spontaneous and endothermic process, suggesting a physisorption mechanism. A Taguchi orthogonal array (L27) experimental design was used to determine the optimum conditions for the removal of dye. Various desorbing agents were used to investigate the regeneration possibility of used adsorbent.

The structure of the ligand and the structure of the new synthesized copper complex were elucidated by all the above mentioned analysis methods. The formation of the azo metal complex with Cu(II) was confirmed by UV-Vis spectrum. Thermogravimetric and spectral analysis reveal its different stability in the air and nitrogen atmosphere, with high nitrogen stability. The PXRD analysis shows crystalline structure for the copper complex. At the same time, the color analysis was performed for the ligand and the synthesized complex in powder by means of UV-Vis CIEL*a*b* color space parameters, under the CIE recommended illumi...</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="d2b2a72d5e6f170fa5b521ca057dd712" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":78801549,"asset_id":68263348,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/78801549/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="68263348"><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="68263348"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 68263348;
