class="volume-info volume-info-text volume-info-description"> Abstract: The concept of developing a bamboo-based Nylon 66 polymer matrix composite is a relatively novel and very new technical attempt through friction stir processing (FSP). This innovative approach can create a composite material that strengthen the mechanical properties of bamboo and the versatility of Nylon 66. However, successful implementation requires careful consideration of FSP process parameters such us tool rpm, traverse speed, tilt angle and tool design. Among the processing parameters, the tool rpm shows the significant role for severe plastic deformation and temperature generation which leads to the achieving excellent bond. Therefore, in this present study attempt has made to develop the polymer matrix composite (nylon 66 and bamboo powder) using FSW process at a variant rotational speed of 300,400 and 500 rpm with the constant traverse speed of 25 mm min<sup>-1</sup>. The deformation behavior and the peak temperature evolved under the tool shoulder during the stirring motion is studied using COMSOL Multiphysics simulation. It is found that, the specimen processed with higher rpm (500rpm) shows the higher volumetric strain and the peak temperature and it is evident that with increasing rpm the higher amount of severe plastic deformation occurred. Initially the process parameters are optimized without bamboo powder on the nylon 66 plate of 6 mm thickness and found that the 500 rpm processed specimen shows the defect free. Prior to the actual FSP, the small keyways taken on the center of the nylon 66 plate in order to add the bamboo powders in it. Actual processing was done with bamboo powder after adding natural bamboo powder of size 50µm. The result reveals that, the bamboo powder has partially expelled out during the period of FSP. This complete study concedes that the processing parameters needs to be optimized and also bamboo added method need to be studied for the successful development of bamboo-based polymer matrix composite. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613524', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 3 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.9">Influence of Silicon Carbide Incorporation on Thermal and Ablation Properties of Carbon Fabric-Phenolic Resin Composites</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Basingala Praveen Kumar, N.V.

This work involved the fabrication of composites using a polyacrylonitrile (PAN) based carbon fabric (Cf)-phenolic resin matrix (PR) modified with different weight percentages (wt.%) of silicon carbide (SiC), namely 0 wt.% (Cf/PR), 1wt.%, 3wt.%, and 5wt.%. The composites were prepared using the hydraulic hot press method. The manufactured composites were analyzed for their thermal conductivity and resistance to ablation using an oxyacetylene torch test. Furthermore, the ablated composites underwent X-ray diffraction (XRD), revealing a SiO<sub>2</sub> compound layer on the ablated composite surface. The experimental results demonstrated that the Cf/PR composites modified with 3wt.% of SiC exhibited superior characteristics. The composites consist of 3wt.% Cf/PR-SiC exhibited a thermal conductivity value of 0.57 W/m K. Additionally, these composites showed a noticeable decrease in the mass ablation rate (MAR) at 0.0052 mm/sec and linear ablation rates (LAR) at 0.025061 gm/sec. This study proposed an effective way to improve the thermal and ablation characteristics of TPS materials. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613531', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 9 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.17">Quasi Solid Polyzwitterion- Polyacrylamide Electrolytes for Rechargeable Zinc-Ion Battery</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Pannarot Kitpimonkul, Amornrat Khampuanbut, Prasit Pattananuwat </div> </div> <div id="abstractTextBlock614134" class="volume-info volume-info-text volume-info-description"> Abstract: Zinc-ion batteries have attracted significant attention due to their low cost, rechargeability, and superior safety features. In fact, the use of aqueous electrolytes negatively affects battery performance due to the solid electrolyte interface (SEI), creating zinc corrosion, hydrogen evolution reaction (HER), and dendrite formation. To address these challenges, quasi-solid electrolytes (QSE) based on polyacrylamide-poly (3-(1-vinyl-3-imidazolio) propanesulfonate) (PAM/PVIPS) have been developed. PAM stands out as matrix QSE due to its excellent flexibility and electrochemical stability. PVIPS offers a well-defined pathway for ion transportation caused by cationic and anionic groups in structure. Clearly, the asymmetrical zinc cell with PAM/PVIPS QSE effectively reduces the overpotential profile, prolongs the stabilized zinc plating/stripping and enhances ionic conductivity, compared to PAM QSE. Additionality, the performance of Zn||δ-MnO<sub>2</sub> is also enhanced with PAM/PVIPS QSE, yielding the specific capacity value of 65 mAh g<sup>-1</sup>, which is superior to the pristine PAM QSE (56 mAh g<sup>-1</sup>). </div> <div> <a data-readmore="{ block: '#abstractTextBlock614134', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 17 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.23">3D-Printed Flexible Polyacrylamide/Alginate Gel Polymer Electrolyte for Zinc-Ion Batteries</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Napassorn Wongduangpa, Nutthapong Poompiew, Chuanchom Aumnate, Pranut Potiyaraj </div> </div> <div id="abstractTextBlock614063" class="volume-info volume-info-text volume-info-description"> Abstract: Flexible and wearable electronics are increasingly popular and utilized in various forms. Batteries have become essential as an energy source for wearable electronics. To meet demands of such electronics, these batteries must remain flexible, lightweight, possess good electrochemical performance, customizable shape, and ensure safety. Zinc-ion batteries (ZIBs) have emerged as a promising energy source for these applications. However, ZIBs encounter challenges due to the lack of flexible electrolytes. Polyacrylamide (PAM) is a polymer widely used as gel polymer electrolytes (GPEs) owing to its versatile electrical conductivity and excellent flexibility. However, PAM alone lacks the mechanical strength required to support flexible and wearable electronics adequately. To address this limitation, alginate (Alg), a polysaccharide with good compatibility with PAM, is incorporated in varying concentrations (0-3 %wt.) to form interpenetrating networks (IPN) hydrogels, with a chemical network of PAM and a physical network of alginate to enhance the overall mechanical properties. Following this, the 3D-printed PAM/Alg hydrogels are immerged in a 2M ZnSO<sub>4</sub> electrolyte to create PAM/Alg gel polymer electrolytes (PAM/Alg-GPEs). This process significantly improves the mechanical properties of PAM/Alg-GPEs. Subsequently, the ionic conductivity of these 3D-printed PAM/Alg-GPEs is evaluated using electrochemical impedance spectroscopy (EIS). The results demonstrate that PAM/Alg-GPEs exhibit the desired flexibility along with sufficient electrochemical performance, making them promising candidates for use as wearable electrolytes in zinc-ion batteries. </div> <div> <a data-readmore="{ block: '#abstractTextBlock614063', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 23 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.31">Impact of Pre-Silica-Coating on the Luminescence Properties of Silica-Coated Indium Phosphide Nanoparticles</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Mizuki Ito, Noriko Yamauchi, Kouichi Nakashima, Yoshio Kobayashi </div> </div> <div id="abstractTextBlock613583" class="volume-info volume-info-text volume-info-description"> Abstract: This study examined the impact of silica-coating on the luminescence characteristics of indium phosphide (InP) nanoparticles. Silica-coated InP nanoparticles were prepared using three different techniques. The first method utilized tetraethoxysilane (TEOS) as the silica source, resulting in the encapsulation of multiple InP nanoparticles within silica spheres. This approach caused a red-shift in the luminescence peak wavelength of the InP colloidal solution post-TEOS coating, compared to the original InP colloidal solution. Conversely, the second method employed tetramethoxysilane (TMOS), resulting in the formation of irregularly shaped silica-coatings on multiple InP nanoparticles, which reduced the red-shift in the luminescence peak wavelength of the silica-coated InP colloidal solution. The third method involved pre-coating InP nanoparticles with TMOS, followed by thickening the silica shells using TEOS. This technique successfully encapsulated multiple InP nanoparticles within silica spheres, maintaining the luminescence peak wavelength of the InP colloid solution post-coating with TMOS and TEOS nearly identical to that of the original solution. This method merged the advantageous outcomes of the first two methods. Additionally, silica spheres containing InP nanoparticles synthesized using both TMOS and TEOS exhibited the highest luminescence intensity. In summary, this study introduces a novel approach in nanoparticle engineering, enhancing the functional properties of InP nanoparticles and expanding their potential applications in optoelectronic devices. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613583', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 31 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.39">Influence of Chelants and Catalyst on Luminescence of CaAl<sub>2</sub>O<sub>4</sub>:Eu<sup>2+</sup> Phosphors for Optical Temperature Sensing Applications</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Su Hua Yang, Yi Yan Tsai, Chih Chieh Ho </div> </div> <div id="abstractTextBlock613573" class="volume-info volume-info-text volume-info-description"> Abstract: This study synthesized CaAl<sub>2</sub>O<sub>4</sub>:Eu<sup>2+</sup> blue phosphors using the sol-gel method.

No significant changes were observed in the photoluminescence (PL) spectra of the phosphors when different precursor solutions were used. However, the use of PEG and citric acid led to a noticeable decrease in the PL intensity. Notably, the use of HCl resulted in an increase in PL. In addition, upon heating the phosphors from room temperature to 110 °C, the PL spectrum remained unchanged, whereas the PL intensity decreased linearly with increasing temperature.

For optimal performance, electrical conductivity, electrical sensitivity, and flexibility are major properties of strain sensors. Polyurethane (PU) shows promise for custom strain sensors due to its high flexibility. Additionally, using digital light processing (DLP) 3D printing to shape PU is suitable for detecting body movements. Therefore, the aim of this study is developing 3D-printed PU to strain sensing devices, utilizing the surface coating method on 3D-printed PU with carbon black (CB) and polydimethylsiloxane (PDMS) to fabricate the (PDMS+CB)/CB/PU strain sensor. The conductive network of CB enhances sensitivity, while PDMS is incorporated to act as an adhesive for the durability of CB on the PU surface. The results of the experiment reveal a gauge factor of 6.04 with range from 1 to 10% elongation. The strain sensor of this study has high potential to use for strain sensing technology and is capable of detecting small body movements. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613710', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 45 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.51">Polyol Synthesis of Bimetallic FePt Nanoparticles over h-BN Substrate</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Anton S.

Multicomponent metallic NPs, such as bimetallic FePt NPs, are attracting much attention as catalytically active sites because their properties can be superior to their single-element counterpart. To achieve the best catalytic properties, careful control of the chemical composition of the bimetallic NPs on the surface of h-BN substrates is necessary. Herein we report the development of a polyol synthesis protocol that elucidates the relationship between the initial and resulting Fe:Pt molar ratio in a FePt/h-BN material. TEM, STEM, EDXS, BET and BJH methods were utilized to characterize the surface and structure of the h-BN support and FePt/h-BN heterostructures. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613605', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 51 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1128.59">Influence of Density of 3D Printing Using the Fdm Method on Productivity and Mechanical Properties of ABS</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Vesna Petrović, Aleksandrar Čabrilo, Vladimir Blanuša, Petra Balaban, Branko Savić, Gabriela Victoria Mnerie </div> </div> <div id="abstractTextBlock606009" class="volume-info volume-info-text volume-info-description"> Abstract: The economic and technical advantages of 3D printing make it a possible replacement for conventional production processes, especially for complex products and small batches. It is important to point out that technological parameters of 3D printing, such as layer thickness, print density, print speed, melting temperature, and table temperature, have a significant impact on the mechanical properties and productivity of parts obtained by 3D printing. Because of all the above, there is a great interest in research in this area. The paper presents the results of testing the tensile strength of the ABS polymer, in which two parameters were varied: the thickness of the print layer (0.39 mm) and the print density of 60–100% in steps of 10% each. The samples were obtained on a ZORTRAX M200+ 3D printer using fused filament deposition (FDM) technology. The selected thickness of the printing layer is relatively large, and with it, parts with lower accuracy and high surface roughness are obtained, although at the same time high productivity is achieved, which can satisfy some requirements. The obtained tensile strength values show that increasing the print density leads to an increase in its value, with a deviation in the sample with a print density of 100%, whereas the tensile strength values are comparable to the values obtained by other authors. </div> <div> <a data-readmore="{ block: '#abstractTextBlock606009', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 59 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 14 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/MSF.1128/2">2</a></li><li class="PagedList-skipToNext"><a href="/MSF.1128/2" rel="next">></a></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.
