inherent disadvantages. It has been replaced everywhere with modified starches of various kinds. Studies have shown that polyelectrolyte flocculants can be created on the basis of starch if ionizable groups are introduced into the macromolecules of amylose and amylopectin. At the same time, it was found that the treatment of starch with oxidizing agents (of various natures and activities) can significantly improve the functional properties of native starch when gluing, used for surface sizing, and as a binder for corrugated cardboard. In this work, we also obtained oxidized starch in order to create an adhesive binder on its basis, and only local raw materials were used. It is shown that this method makes it possible to regulate the number of functional groups (oxidizing effect, or OE) in oxidized starch and its paste viscosity within a wide range. This is achieved by changing the molar ratio of the catalyst and oxidizer. During the oxidation process, it is possible to vary the concentration ratios of the oxidizer, catalyst, and conditions. Using FeSO<sub>4</sub> as a catalyzer, the oxidized starch pastes show a less pronounced pseudoplasticity and are characterized by reduced viscosity. The analysis showed that during the oxidation of corn starch with hydrogen peroxide, changes in the supramolecular structure of starch are insignificant: a certain repeated decrease in the level of crystallinity takes place, which leads to a decrease in the gelatinization temperature and also the viscosity of starch pastes. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604669', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 43 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/CTA.13.19">Utilization of SiO<sub>2</sub> for Assessing Bitumen Characteristics through Consistency Tests</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Muhammad Naveed Ishaq, Naveed Anjum, Zaheer Ahmed, Asad Javed, Junaid Sidiqy, Musharaf Khan </div> </div> <div id="abstractTextBlock611200" class="volume-info volume-info-text volume-info-description"> Abstract: Bitumen, a fundamental component of asphalt used in road construction, plays a vital role in determining the performance and longevity of pavements. The assessment of bitumen characteristics is crucial to ensure its suitability for specific applications and environmental conditions. This research paper explores the use of fumed silica, a high-purity, fine particulate form of silicon dioxide, as an additive in bitumen to improve its properties. The study investigates the impact of Fumed Silica SiO2 on the results obtained. The following tests, including the specific gravity test, penetration test, softening point test, and flash and fire test were used to determine the rheological characteristics of bitumen. In particular, the treated bitumen qualities were concentrated after performing lab testing by breaking down the rheological properties. The research aims to enhance the understanding of how SiO2 affects bitumen properties and its potential benefits in enhancing the performance of road pavements. According to this study, 0.1 wt. % of fumed silica produces the results mentioned above better than larger concentrations of fumed silica. </div> <div> <a data-readmore="{ block: '#abstractTextBlock611200', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 19 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/DDF.433.21">Non-Arrhenius Transport Properties of Glass-Forming Materials in a Wide Temperature Range: A Systematic Study Based on the BSCNF Model</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Masahiro Ikeda, Masaru Aniya </div> </div> <div id="abstractTextBlock610124" class="volume-info volume-info-text volume-info-description"> Abstract: The understanding of the non-Arrhenius transport properties in glass-forming materials is of great importance from both, fundamental and applied points of views. In the present paper, we show that our model, the bond strength-coordination number fluctuation (BSCNF) model describes the temperature dependence of the non-Arrhenius transport coefficients in a wide temperature range. The BSCNF model also enables to characterize the glass-forming materials in terms of the mean values of the bond strength <i>E</i><sub>0</sub>, the coordination number <i>Z</i><sub>0</sub> and their fluctuations Δ<i>E</i> and Δ<i>Z</i> of the structural units that form the melts. Importantly, in the light of the BSCNF model, one can discuss the physical implications of the materials that extend from the strong to fragile systems in a systematic way compared to other popular models. In addition, we present a new theory of the vacancy formation, and briefly mention that the extended theory along with the BSCNF model can be applied to discuss the freezing of defects. </div> <div> <a data-readmore="{ block: '#abstractTextBlock610124', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 21 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/DDF.432.121">Halloysite Nanotube (HNT) Dispersion Stability in 10% Ethanol-Water Mixture and Water</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Aaron Zaeh F.

Overall, the study finds that changes in HNT concentration linearly affect the response variables and showed that the 10% ethanol solvent has a higher zeta potential, smaller particle size, higher viscosity, and settling velocity. The enlargement of HNT particles at 10% ethanol while keeping better stability than water solvent is unexpected and can open novel studies about the dispersion of HNT in this solvent system. </div> <div> <a data-readmore="{ block: '#abstractTextBlock607266', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 121 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1118.85">Laboratory Investigation and Empirical Modelling of Polymer Solution Viscosity</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Yazan Firas Fuad Hussein, Altamish Ahmed Pakeer, Rizwan Muneer, Muhammad Rehan Hashmet, Younes Alblooshi </div> </div> <div id="abstractTextBlock609114" class="volume-info volume-info-text volume-info-description"> Abstract: Polymer flooding, an improved oil recovery technique, is a well-established method for improving oil production. Although numerous polymers have been suggested in the literature, identifying suitable ones for applications in high-temperature and high-salinity carbonate reservoirs remains a challenging task. The viscosity of polymer solutions depends on various parameters, including polymer concentration, temperature, and shear rate. Therefore, screening polymers for these demanding conditions necessitates meticulous experimental work. In this experimental study, polymer solutions' physical property—viscosity—was measured as a function of polymer concentration, temperature, and shear rate. Subsequently, the generated rheological data were used to develop empirical models capable of predicting the viscosity of polymer solutions under various conditions. An acceptable match was achieved between the experimental and model-predicted data. Furthermore, a validation was conducted for the empirical models, yielding a root mean square error of 1.75. These models will significantly reduce the number of experiments required for the screening process and prove valuable for optimization procedures. </div> <div> <a data-readmore="{ block: '#abstractTextBlock609114', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 85 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1114.73">Dissolving Pulp from Sansevieria Trifasciata Fiber Processed with Water-Pre-Hydrolysis, Soda-Anthraquinone Cooking and Clorine Free Bleaching<i> </i></a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Yusnimar Yusnimar, Khairat Khairat, Drastinawati Drastinawati, Chairul Chairul, Syamsu Herman, Suci Ramadhana </div> </div> <div id="abstractTextBlock594544" class="volume-info volume-info-text volume-info-description"> Abstract: For a long time, rayon has been produced using dissolving pulp (DP). DP is typically made from wood or cotton, but it takes a long time to collect wood, and high-quality cotton must be imported from afar. Sansevieria trifasciata (ST) fiber, which contains more than 50% cellulose, offers potential as a raw material and a substitute for cotton and wood. It is simple to develop and grow. It can endure a wide range of light and temperature conditions. By using the water-pre-hydrolysis, soda-Anthraquinone cooking (soda-AQ), and elementary-chlorine-free (ECF) bleaching sequences, this work aims to convert ST into DP. Results, The DP was produced with a yield of 43.69%, a kappa value of 4.73, a viscosity of 9.3 cP, an alpha-cellulose content of 97.7% and a brightness of 90.7%, which was higher than the ISO brightness of 88%. The DP quality corresponds to the minimum DP level for rayon according to the Indonesian National Standard (SNI). It is very promising for further development, such as being used for viscose fiber production. </div> <div> <a data-readmore="{ block: '#abstractTextBlock594544', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 73 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/DDF.431.147">Important of Slip Effects in Non-Newtonian Nanofluid Flow with Heat Generation for Enhanced Heat Transfer Devices</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Olayinka Akeem Oladapo, Akintayo Oladimeji Akindele, Adebowale Martins Obalalu, Olusegun Adebayo Ajala </div> </div> <div id="abstractTextBlock600378" class="volume-info volume-info-text volume-info-description"> Abstract: In various fields such as engineering, nanotechnology, and biomedical sciences, the study of non-Newtonian nanofluid flow with heat generation is becoming increasingly important. However, it is challenging to accurately model such flows due to their complex behavior and slip effects at the fluid-solid interface. This research investigates the impact of first and second-order slip conditions on the flow and heat transfer properties of a non-Newtonian nanofluid using a power law model to describe the fluid's non-Newtonian behavior and numerical methods to solve the resulting equations. To determine the influence of various parameters such as slip parameters, Brinkman number, power law index, and Eckert number on the velocity, temperature, and concentration profiles, which this study examines. The study shows that slip parameters significantly determine the flow and heat transfer properties of non-Newtonian nanofluids, the study also reveals that slip parameters are a crucial factor in understanding the flow and heat transfer characteristics of nanofluids, with the second-order slip condition having a greater impact on velocity and temperature profiles than the first-order slip condition. These findings are valuable for developing and optimizing heat transfer devices that involve non-Newtonian nanofluids with heat generation, which is essential for technological advancements in today's industry. </div> <div> <a data-readmore="{ block: '#abstractTextBlock600378', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 147 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/SSP.353.143">Diffusion in Metallic Glass-Forming Systems: A Description of the Kink Behavior Observed in the Temperature Dependence</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Masaru Aniya, Masahiro Ikeda </div> </div> <div id="abstractTextBlock601624" class="volume-info volume-info-text volume-info-description"> Abstract: The temperature dependence of the diffusion coefficient in metallic glass-forming systems do not follow the Arrhenius behavior over a wide temperature range. Instead, it exhibits a kink behavior at around the glass transition temperature. Some researchers associate this behavior to the difference in the diffusion mechanism operating in the glassy and the supercooled liquid state, whereas others do not support this view. In addition, usually, the temperature dependence of the diffusion coefficient is analyzed by splitting the temperature range into two regions, above and below the glass transition temperature. In the present study, we developed an analytical theory that describes the continuous variation of the diffusion coefficient across a temperature where the kink behavior is observed. According to the theory, the kink behavior arises from the freezing of free volume available for diffusion by lowering the temperature. A connection to the vacancy mechanism of diffusion has been also pointed out. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601624', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 143 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.958.157">Design of Pastes for Direct Ink Writing of Zirconia Parts with Medical Applications</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Irene Buj-Corral, Jos&#xE9; Antonio Padilla, Joaquim Minguella-Canela, Lourdes Rodero, Llu&#xED;s Marco, Elena Xuriguera </div> </div> <div id="abstractTextBlock599265" class="volume-info volume-info-text volume-info-description"> Abstract: Direct ink writing (DIW) is an extrusion additive manufacturing (AM) technique in which inks are extruded through a nozzle and then deposited layer-by-layer. This technology allows 3D printing many different materials such as ceramics, metals, food, etc. In this work, the performance of zirconia pastes is addressed. The pastes are composed of yttria stabilized zirconia (YSZ) powder and a polymeric binder. Ceramic content is a mix of two components: A and B. Both the total content of ceramic and the content of component A in the paste are varied, according to a 3<sup>2</sup> design of experiments. The paste was characterized regarding Densification (%) and Elastic modulus G’ (Pa). A new parameter w<sup>3</sup>/G’ is defined to evaluate the viscosity of the inks. In the tests, the ceramic percentage is limited by the pressing force of the plunger that will be used to extrude the pastes. On the other hand, the binder concentration is also limited, because it requires to be in a gel form in order to be properly extruded. The results showed that Densification depends mainly on ceramic content, while the w<sup>3</sup>/G’ parameter is related to percentage of component A. In this work, the properties of the pastes prior to 3D printing are assessed. However, in the future, the pastes will be used to extrude complex parts with medical applications. AM extrusion processes constitute a possible way to overcome the difficulties to obtain complex geometries with conventional methods such as machining, in which zirconia parts can break due to their brittleness. Thus, the results of this work will help to manufacture complex shapes with porous areas in zirconia, when the DIW technology is employed. </div> <div> <a data-readmore="{ block: '#abstractTextBlock599265', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 157 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.957.29">Manufacturing of Novel Cork-STF Composites Designed for Impact Energy Absorption</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Guilherme J.

Recent advances show their potential for engineering applications, such as developing shock absorbers and impact energy-absorbing structures. There is a search for sustainable materials for several applications due to the critical need to replace nonrenewable raw materials. Cork is a sustainable material reported to be an excellent alternative to synthetic energy absorbers thanks to its cellular microstructure and cell wall composition. This work explores the development of cork-STF composites designed for impact energy mitigation. The cork-STF composites were manufactured by compression moulding, exploring different compositions of both materials. Additionally, the manufactured compounds were characterized by submitting samples to impacts. The results made it possible to conclude that deagglomeration occurs for STF concentrations higher than 20%. On the other hand, good results were achieved with compounds that have less than 20% of STF in their composition and can withstand impact loading. Therefore, the energy absorption of white cork agglomerates decreases with STF. Nevertheless, the agglomeration was successful, and this design can be adapted for other specific purposes, applications, or even strain rates than the ones explored in this work. </div> <div> <a data-readmore="{ block: '#abstractTextBlock599096', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 29 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> Showing 1 to 10 of 557 Paper Titles </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/paper-keyword/viscosity/2">2</a></li><li><a href="/paper-keyword/viscosity/3">3</a></li><li><a href="/paper-keyword/viscosity/4">4</a></li><li><a href="/paper-keyword/viscosity/5">5</a></li><li class="PagedList-ellipses"><a class="PagedList-skipToNext" href="/paper-keyword/viscosity/6" rel="next">…</a></li><li class="PagedList-skipToNext"><a href="/paper-keyword/viscosity/2" rel="next">></a></li><li class="PagedList-skipToLast"><a href="/paper-keyword/viscosity/56">>></a></li></ul></div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy &amp; Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/read-and-publish-agreements">Read &amp; Publish Agreements</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> &#169; 2024 Trans Tech Publications Ltd.
