for volume fraction in polylactic acid based on a heat energy storage system was examined by using the T-history method. The use of the T-history method for the assessment of thermo-physical boundary describes the specific heat capacity and thermal conductivity enhanced in solid as well as liquid phases of the mixture until the addition of 0 to 0.025% of volume part of zinc oxide in the polylactic acid nanocomposite. After the addition of the zinc oxide, the heat of fusion falls and polylactic acid has a high rate of fusion related to 0.025% volume part of zinc oxide mixed with polylactic acid. Further zinc oxide-based polylactic acid nanocomposite has 31.30% and 13.5% higher solid as well as liquid thermal conductivity in comparison with polylactic acid. Moreover, raise the particle size and analysis as well as distributions found by dynamic light dispersing method for different volume parts of zinc oxide mixed on polylactic acid. In contrast to the thermal efficiency analysis of 0.025% of volume fraction zinc oxide in polylactic acid nanocomposite has a 30.6% high heat transfer rate related to pure polylactic acid along the stage of 4 minutes. Further, the addition of zinc oxide above 0.025% volume fraction in polylactic acid, rise the particle settlement rate freely. Whatever can become to end that 0.025% volume fraction of zinc oxide in polylactic acid mixed thermal energy storage arrangement outcome of maximum thermo physical property and thermal efficiency. </div> <div> <a data-readmore="{ block: '#abstractTextBlock602855', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 89 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1100.103">Preparation and Characterization of a Novel Additive for Elastomeric Polymer from Oligoisoprene Modified Mesoporous Silica</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Nathapong Sukhawipat, Laksana Saengdee, Narongrit Sosa, Pongtanawat Khemthong, Jatuporn Wittayakun, Pamela Pasetto </div> </div> <div id="abstractTextBlock603255" class="volume-info volume-info-text volume-info-description"> Abstract: This manuscript presents a novel instant additive for elastomeric polymers, specifically focusing on the modification of synthesized mesoporous silica using carbonyl telechelic natural rubber (CTNR). The surface of mesoporous silica particles was modified using a two-step approach. In the first step, a strategy involving the grafting of 3-aminopropyltriethoxysilane (APTES) onto the silica particles was employed. Subsequently, in the second step, a Schiff's base reaction was carried out between the aldehyde functional group of CTNR and the amines on the modified silica surface. The grafting percentage achieved through this process was determined to be 4.70%. This novel instant additive has the potential to enhance the properties and performance of elastomeric polymers by leveraging the unique characteristics of CTNR and the mesoporous silica surface. Further investigations and applications of this additive can contribute to advancements in the field of elastomeric polymer materials. </div> <div> <a data-readmore="{ block: '#abstractTextBlock603255', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 103 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1100.111">Development of a Corrosion Model Ofthermal Elenents of Nuclear Power Plants</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Yuliana Hapon, Maksym Kustov, Yuliia Mykhailovska, Maryna Chyrkina </div> </div> <div id="abstractTextBlock599024" class="volume-info volume-info-text volume-info-description"> Abstract: Nuclear power plants (NPPs) result in accumulation of a significant amount of radioactive products during the process of their storage and the presence of a potential release of radioactive products, in the case of an accident that is a source of potential hazard and risk of radiation impact on the personnel, population and environment in general.

A database of thermodynamic data has been created: enthalpies, entropies and coefficients of the heat capacity equation, necessary for the study of multicomponent systems, including barium aluminates. Since the basis of modern materials science is multicomponent systems, on their basis it is possible to create various combinations of phases in structural materials with a set of specified properties. Thus, modern thermodynamics is not a frozen science. It is known that the objects of research are expanding, where thermodynamic methods can be applied to study the area of high and low temperatures, the area of very low and high pressures. And new discoveries give birth to new areas of application of thermodynamics: thermodynamics of thermonuclear reactions, plasma thermodynamics, relativistic thermodynamics, thermodynamics of negative absolute temperatures, etc. And, finally, the methods of thermodynamic research themselves do not remain unchanged: the exergy method, the methods of thermodynamics of irreversible processes, etc. At present, the thermodynamic method of research is widely used in various fields of physics, chemistry, biology, and many other sciences and branches of technology. Being one of the most extensive areas of modern natural science, thermodynamics plays an important role in the system of knowledge necessary for an engineer of any specialty in his practical activities. Chemical thermodynamics, on the other hand, paid the greatest attention to the study of phase transitions and the properties of solutions, and in relation to chemical reactions it was limited mainly to determining their thermal effects. To some extent, this is due to the fact that it was these areas of chemical thermodynamics that were the first to satisfy the needs of production. The practical use of known methods of thermodynamics of chemical reactions for solving major industrial problems for a long time lagged behind its capabilities. </div> <div> <a data-readmore="{ block: '#abstractTextBlock600881', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 139 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1100.149">Stability of Individual Phases in the Elastic Matrix of a Composite</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Oleksii Goryk, Stanislav Koval’chuk, Volodymyr Muravlov, Yuliia Skoriak </div> </div> <div id="abstractTextBlock600747" class="volume-info volume-info-text volume-info-description"> Abstract: A methodology for analytical stability assessment of individual compressed flexible phases of discretely heterogeneous composite elements of engineering structures is proposed to ensure their reliable safe operation and minimise the consequences of emergencies.

The authors have made a special stand, the design of which allows to carry out researches of bearing capacity and deformability of such systems under the concentrated and distributed static loads. Samples made of reinforced concrete and steel fiber concrete and consisting of four mutually perpendicular beams of rectangular cross-section were tested. The specimens were reinforced in the lower zone with longitudinal reinforcement of 8 mm in diameter, two rods in each beam. Steel-fiber concrete specimens have an additional dispersed reinforcement of steel fiber with bent ends in an amount of 1% by volume of concrete. A procedure of finite-element modeling and calculation of cross-beam systems in the licensed program ANSYS 17.1 was developed, and a comparison of the results obtained experimentally and on the basis of computer modeling was performed. The tests showed that dispersed reinforcement of the cross-beam system with steel fiber leads to an increase in its bearing capacity by 1.23 times. During modeling and finite-element analysis in the ANSYS 17.1 program, the increase in bearing capacity was 1.18 times. At the same time, the load-carrying capacity of the reinforced concrete cross-beam system obtained by the finite-element method was 13% lower than in the experiment, and that of the fiber-reinforced concrete system was 15% lower. At the same time, the discrepancy in the approaches considering torsion and not taking it into account is about 5% for all the samples studied in the work. </div> <div> <a data-readmore="{ block: '#abstractTextBlock598363', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 167 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 11 to 19 of 19 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="PagedList-skipToPrevious"><a href="/MSF.1100" rel="prev"><</a></li><li><a href="/MSF.1100">1</a></li><li class="active"><span>2</span></li></ul></div> </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 & 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 & 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> © 2024 Trans Tech Publications Ltd.
