Studies show that it is an efficient and practical tool to combat the ill effects of urbanization. Installing a green roof system involves growing vegetation on rooftops and is used as a tool to help mitigate the negative effects of pollution. Green roofs may not act as cooling devices but obviously serve as heat insulation, reducing the heat flux through the roof. In this study, the proponents explore possibilities in developing a green roof system by utilizing wood-plastic materials to create soil trays where roof grass can be cultured and can be interconnected on roof areas. The study highlights the properties of the materials to be utilized in the design of soil trays, the schematic design of the wood-plastic soil tray composite (wpstc) and the green roof design for efficiency and functionality test were also presented. The physical and mechanical properties of the polymerized coir-wood boards for soil trays were assessed by determining its water absorption, thickness swelling, modulus of rupture and impact strength. The succeeding phase of the study which describes the energy efficiency test, and the functionality test was also disclosed in the summary of this paper. </div> <div> <a data-readmore="{ block: '#abstractTextBlock613035', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 75 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1123.83">Enhancing Mechanical Properties with Water Hyacinth Fiber-Reinforced Bio-Based Epoxy Composites</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Naruemon Sumrith, Nipon Bhuwakiatkhamjorn, Kittipat Keawked, Paweenvat Iamim, Chakaphan Ngaowthong </div> </div> <div id="abstractTextBlock610433" class="volume-info volume-info-text volume-info-description"> Abstract: The purpose of this research is to examine how the size and quantity of water hyacinth (WH) fibers impact their reinforcement of bio-based epoxy resin, with a specific focus on how these factors influence mechanical properties. The study involves utilizing specimens containing WH fiber particle sizes of 100 碌m and 500 碌m, combined with varying proportions of 10%, 20%, and 30% by volume. The application of sodium hydroxide (NaOH) as a chemical treatment for the fibers enhances the mechanical characteristics of the composite. The results indicate that the tensile modulus of 30WH100 exceeds that of neat epoxy by roughly 17.6%. Noteworthy is the hardness value of 10WH100 at 99.73 HRL, compared to the value of 99.98 HRL seen in neat epoxy.

Vitrimer materials provide opportunities for recycle thermosets and CFRP composites, however, the retained properties of composite still limit their applications. In this research work, the focus is to investigate material properties of vitamer/carbon fiber composite and the retained properties after recycling of the same. A vitrimer material has been developed using an epoxy (EP) matrix and bio-based curing agent and citric acid (CA), and finally reinforced with carbon fibre. The vitrimer materials were prepared with varying ratios of acid to the epoxy ratio between 0.30 and 0.40 to prepare the best performance vitrimer. Fourier transform infrared (FTIR) spectrometry was conducted in Transmittance mode over a range of wavelengths from 400 to 4000 cm<sup>-1</sup>. The mechanical testing carried out at room temperature under tensile loading. Results found that the Vitrimer composite could be effectively dissolved in DMF, enabling the recovery of the carbon fibers. The results of the study indicate that the EP/CA vitrimers exhibit thermomechanical properties that are comparable to those of the epoxy vitrimer cured using a petroleum-based curing agent. The most important results that demonstrate the use of EP/CA vitrimers may be a promising alternative to traditional epoxy composites in various applications. </div> <div> <a data-readmore="{ block: '#abstractTextBlock611125', 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.1123.95">Enhancing Dispersion Ability and Bond Strength of Boron Nitride with Epoxy Resin by Ar<sup>+</sup> Ion Beam in Reactive Oxygen Gas Environment</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Wooyoung Jung, Sanghoon Lee, Sangjun Lee, Minwoo Choi, Ho Seok Lee, Seok Keun Koh </div> </div> <div id="abstractTextBlock611193" class="volume-info volume-info-text volume-info-description"> Abstract: Boron Nitride (BN) filler was modified by an ion beam surface treatment to enhance dispersibility to polar solvent and bond strength with epoxy. Surface treatment of the fillers was conducted by Ion Assisted Reaction (IAR), in which Ar<sup>+</sup> ion beam is irradiated on the filler surface with energy of 1keV, dose varied from 1x10<sup>14</sup> ~ 5x10<sup>16</sup> Ar<sup>+</sup> ions/cm<sup>2</sup> by using Cold Hollow Cathode type ion source and oxygen gas 5-10ml/sec. After the surface treatment, the BN powder were spontaneously dispersed into polar solvent in a visual observation which means the modified surface was changed from hydrophobic to hydrophilic, and the powder were easily mixed with a viscous epoxy resin until 40wt% without thinner (a gelation phenomenon with easy blending into the epoxy resin), but the untreated powder exhibits difficulty in mixing with epoxy resin without the thinner. XPS analysis showed oxygen functional groups (B-ON, BN, etc.) were formed on the surface of BN. It was confirmed the surface modification has a high filling ability of the BN filler with binder and better adhesion with epoxy resin compared to the untreated BN filler. </div> <div> <a data-readmore="{ block: '#abstractTextBlock611193', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 95 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1123.101">Research on Joint Strength and Mechanism of Composite/Aluminum Alloy Connections Based on FDS Technology</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Xing Ge, Hai Jiang Liu, Li Bin Zhu, Zi Jian Yu, Chen Yu Wu </div> </div> <div id="abstractTextBlock610480" class="volume-info volume-info-text volume-info-description"> Abstract: This paper applies Flow Drill Screws (FDS) technology to the joining of composite materials and metal materials. It investigates the connection strength and mechanism between thermosetting carbon fiber reinforced composites and metal materials, as well as between thermoplastic carbon fiber reinforced composites and metal materials. The study includes shear tests and metallographic tests to analyze the two types of connections. The experimental results demonstrate the feasibility of using the FDS process for composite materials and metal materials. It is found that the FDS process is more suitable for connecting thermoplastic composites and metal materials compared to thermosetting composites and metal. This type of connection exhibits a smaller damage range at the interface and allows the thermoplastic matrix to effectively fill the threaded connection area after heating. Additionally, the micro-mechanical interlocks generated at the laminate interface can effectively increase the connection strength. </div> <div> <a data-readmore="{ block: '#abstractTextBlock610480', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 101 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1123.109">Green Synthesis of Magnesium Oxide Nanoparticles Using <i>Melaleuca leucadendra </i>Waste</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Yithro Serang, Chang Nan Chen, Meng Jen Lee </div> </div> <div id="abstractTextBlock610123" class="volume-info volume-info-text volume-info-description"> Abstract: In addressing the gap in sustainable utilization of industrial by-products and the limited exploration of natural antioxidants in nanoparticle synthesis, this study focused on synthesizing magnesium oxide (MgO) nanoparticles using by-products from <i>Melaleuca leucadendra</i> essential oil extraction.

Firstly, the dispersion of ZnO was prepared by dispersing ZnO into a mixture of acrylic emulsion and sodium cocoyl isethionate (SCI). The concentrations of acrylic emulsion were observed at 0.1 % and 0.5 %w/v while the ratio of ZnO:SCI was fixed at 1:0.25. The result shows higher concentration of acrylic emulsion could provide higher dispersion stability compared to the lower concentration. Subsequently, NR films were coated with ZnO through two-pot and one-pot methods. It was found that the surface of NR film from two-pot method (2P_film) presented uneven distribution of the ZnO while plate structure of ZnO and acrylic were observed on films surfaces one-pot method (1P0.1_film and 1P0.5_film). The Zn content on 2P_film surfaces observed by EDS was found at 14 % while 1P0.1_film and 1P0.5_film contain at 28 % and 19 %, respectively, due to higher concentration acrylic emulsion results a greater polymer network anchoring on the ZnO. The reductions of antibacterial of 2P_film, 1P0.1_film and 1P0.5_film are similar results at over 99%. It reveals that the low content of ZnO could sufficiently achieve an excellent antibacterial performance. Nevertheless, the lower concentration of ZnO/Acrylic will be conducted in further study. </div> <div> <a data-readmore="{ block: '#abstractTextBlock611198', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 119 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1123.125">Impact of WO<sub>3</sub>-Nanoparticles on the Setting Time and Early Strength for Different Cementitious Materials</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Safaa M.A. El-Gamal, Mostafa Abdellah Sayed, Alaa Mohsen, Mahmoud M.

Due to the high surface area of nanomaterials, it is considered one of the optimal solutions to modify these properties. Accordingly, this work is focused on comparing the impact of laboratory-prepared tungsten oxide nanoparticles (WO<sub>3</sub>-NP) on two cementitious materials: OPC and alkali-activated slag (AAS). The initial/final-setting time and early compressive strength up to 28-days of the OPC and AAS specimens, modified with 1, 2 wt.% WO<sub>3</sub>-NP, were investigated. The results displayed that WO<sub>3</sub>-NP has a significant impact on the acceleration of the initial/final-setting time of both binding materials. Moreover, the optimal dosage from WO<sub>3</sub>-NP (1 wt.%) upgraded the compressive strength by 19.5 and 15.1% for OPC and AAS, respectively after 7 days. The nucleation-seeds and nano-filler effect of WO<sub>3</sub>-NPs are the focal explanations behind improving these properties via the formation of strength-giving phases and then obtaining a compact microstructure as proved by XRD and SEM. </div> <div> <a data-readmore="{ block: '#abstractTextBlock610818', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 125 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 11 to 18 of 18 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="PagedList-skipToPrevious"><a href="/MSF.1123" rel="prev"><</a></li><li><a href="/MSF.1123">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="/open-access-partners">Open Access Partners</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> © 2025 Trans Tech Publications Ltd.
