2D oxide materials, which are transferred from liquid-metal surfaces to substrates. In this study, we fabricated liquid-metal printing 2D tin oxide (SnO) nanosheets on SiO<sub>2</sub>/Si and glass substrates. A large lateral-sized 2D SnO nanosheets of >100 碌m and a thickness of approximately 6.3 nm was fabricated. The 2D SnO nanosheets exhibited a strong optical absorption in the ultraviolet and violet region and its bandgap was estimated to be approximately 2.9 eV. The 2D SnO nanosheets on glass substrates with patterned gold electrodes generated a photocurrent under ultraviolet (UV) light irradiation, demonstrating a potential for optoelectronic applications such as UV detectors. </div> <div> <a data-readmore="{ block: '#abstractTextBlock607295', 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="/KEM.978.81">Hydrogen Production from Rice Husk: Techno-Economic and Life Cycle Analysis</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Khiang Chung Kong, Christina Lee Min Eh, Angnes Ngieng Tze Tiong, Jibrail Kansedo, Wendy Pei Qin Ng, Chun Hsion Lim, Bing Shen How </div> </div> <div id="abstractTextBlock604251" class="volume-info volume-info-text volume-info-description"> Abstract: The abundance of rice husk in some regions of Southeast Asia makes it a potential feedstock for hydrogen synthesis. However, the information on economic and environmental feasibility of its conversion to hydrogen is lacking. This study aims to assess the techno-economic and life cycle sustainability of hydrogen production from rice husk via the thermochemical gasification method. The techno-economic analyses reveal that rice husk-based hydrogen conversion is more financially attractive than conventional hydrogen production technology. The results of the life cycle assessment are also promising, especially with the global warming potential of the rice husk-based hydrogen production being 99.7 % lower than that of natural gas steam reforming. Waste valorization of rice husk into hydrogen is therefore economically and environmentally viable. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604251', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 81 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.978.87">Improving Efficiency of Heat Pump Dryer Using R32 Refrigerant by Nanofluid</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Prapanphong Somsila, Eakpoom Boonthum, Aphainun Namkhet, Umphisak Teeboonma </div> </div> <div id="abstractTextBlock604304" class="volume-info volume-info-text volume-info-description"> Abstract: Drying process are important in many areas in the agriculture and food sectors, including increasing shelf life, improving transportability by reducing product weight or adding value to products. However, the main problem in the drying process is the relatively high energy consumption. Therefore, the development of energy-saving dryers is necessary. Based on the above reasons, this research aims to study the performance enhancement of heat pump dryers using R32 refrigerant by using heat recovery and nanofluid. The heat that is exhausted from the refrigerant by a heat exchanger. In this work, a Nano titanium dioxide (Ti<sub>2</sub>O<sub>3</sub>) was selected. Pork was dried under the conditions of drying temperature of 45, 50 and 55 掳C and water flow rate in the heat exchanger at the front of the drying chamber of 2, 3 and 4 L/min. Criteria for evaluating heat pump dryer performance include drying rate, specific moisture extraction rate, specific energy consumption, heat pump dryer performance coefficient compared to heat pump dryers without nanofluid. The results showed that increasing the drying temperature and water flow rate in heat exchanger increased the drying rate, power and specific moisture extraction rate in the heat pump dryer using nanofluid. Whereas, the specific energy consumption was lower than the case without nanofluid. Increasing the drying temperature and the water flow rate in the heat exchanger had relatively little effect on the coefficient of performance (COP) of the heat pump dryer. Moreover, the study found that the coefficient of performance of heat pump dryer with nanofluid was in the range of 4.33 - 4.42. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604304', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 87 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.978.97">Comparative Study on Performance of Passive and Active Solar Dryer</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Eakpoom Boonthum, Sirichai Sirichana, Aphainun Namkhet, Umphisak Teeboonma </div> </div> <div id="abstractTextBlock604326" class="volume-info volume-info-text volume-info-description"> Abstract: Performance of solar dryers were tested. In the past, to study the efficiency of solar dryers. A dryer with one drying chamber was built and tested by changing the conditions. In each experiment, the solar irradiance value is different, which can cause the results to be inaccurate. Therefore, in this study, a number of drying chambers are designed according to the number of experimental conditions to be studied during the same period. To reduce factors that will cause discrepancies in the experimental results. The solar dryer with 4 drying chambers was constructed in 1 unit and tested the performance of passive solar dryer (PSD) and active solar dryer (ASD). Air flowrate of ASD varied at 0.03 m<sup>3</sup>/s (ASD0.03), 0.06 m<sup>3</sup>/s (ASD0.06) and 0.09 m<sup>3</sup>/s (ASD0.09). Pork was selected as testing material with initial moisture content of 265% dry basis. Drying rate, solar dryer efficiency and specific energy consumption are criteria to evaluate of solar dryer performance. Result from the experimental was found that the performance of PSD is lowest compared with ASDs. Furthermore, it was revealed that the drying rate of ASD0.06 is higher than that for PSD, ASD0.03 and ASD0.09 by 22% 10% and 8%, respectively. Results from the experimental reveal the ASDs performance are higher than that of PSD. Moreover, it was found that the drying rate of ASD0.06 is higher than that for PSD, ASD0.03 and ASD0.09 by 22% 10% and 8%, respectively. Whereas, specific energy consumption of ASD0.06 is lower than that PSD, ASD0.03 and ASD0.09 by 26%, 11% and 9%, respectively. Finally, it was also found that solar dryer efficiency of PSD, ASD0.03, ASD0.06 and ASD0.09 are 11.68%, 13.34%, 14.89% and 13.73%, respectively. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604326', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 97 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.978.107">Catalytic Pyrolysis of Biomass Waste Mixture over Activated Carbon and Zeolite Catalyst for the Production Bio Oil</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Haniif Prasetiawan, Dewi Selvia Fardhyanti, Hadiyanto Hadiyanto, Widya Fatriasari </div> </div> <div id="abstractTextBlock609128" class="volume-info volume-info-text volume-info-description"> Abstract: Biomass waste is one of the promising resource for the production of bio oil.

The process carried out is distillation, which is heating the PPO at a certain temperature so that light and heavy molecules will evaporate and turn into distillate plastic oil (DPO). The effect of temperature on the quality of the DPO was observed based on the color of the obtained DPO. Temperatures ranging from 120 to 350 掳C were examined in this study. The cleaner DPO was produced at a temperature of about 120 掳C, which indicated a light molecule of hydrocarbon similar to gasoline, while a little dark color was produced when the temperature was increased to 350 掳C, which indicated heavy molecules of hydrocarbon similar to diesel.

It is advantageous to numerically evaluate the hardening characteristics of the pile texture for the development of the products such as towels. Then, the objective of this study is to establish an objective method for evaluating the hardening of the pile due to repeated use. In particular, to determine product specifications, it is necessary to define the conditions under which measurement results are stable. Therefore, for proper design of pile products, objective test methods for repeat use of the pile must be identified. This article reports the effect of repeated indentation testing with a spherical probe on towel samples folded in two to form four layers. A contact theory based on Hertzian theorem is used to evaluate the stiffening of the towel due to repeated indentation. For the properties evaluated in this extended contact theorem, the stiffening behavior is discussed by comparing the changes in the results of 20 repeated tests. In this discussion, the critical times of the indentation test are analyzed to quantify the characteristics of the stiffening behavior of the cotton towels. Analyzing the indentation times shows that critical conditions for the number of tests can be defined. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601693', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 137 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.978.143">Intelligent Identification of Chinese and Australian Merino Wool Fibers Based on Image Recognition</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Xiao Bo Wang, Zhan Xia Chen, Li Jing Wang, Xue Lei Shan, Zi Li Xie, Yun Long Shi, Xiao Ming Qian </div> </div> <div id="abstractTextBlock604606" class="volume-info volume-info-text volume-info-description"> Abstract: In order to promote the sustainable growth of the wool industry and protect consumers' legitimate rights, rapid identification of the country of origin for wool of the same type is deemed crucial. This research presents a computer graphic recognition training model that utilizes median and Wiener filtering techniques to effectively reduce noise in the raw wool fiber images. Employing a support vector machine as the classifier and integrating a polynomial kernel function, this model achieves swift and accurate identification of Chinese and Australian Merino wool fibers. Experimental results underscore that following image recognition training, the model attains an impressive 92.5% comprehensive and precise identification rate for Chinese and Australian Merino wool fibers, effectively distinguishing the origin of wool from the same category. This approach not only provides a valuable reference for identifying the origin of similar wool types but also holds the potential to standardizing the wool fibre material market and assuring the consumer鈥檚 confidence on wool products. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604606', 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.978.149">Neural Network Based Determination of the Degree of Fiber Mixing in Hybrid Yarns and Composites</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Matthias Overberg, Alexander Dams, Anwar Abdkader, Chokri Cherif </div> </div> <div id="abstractTextBlock601580" class="volume-info volume-info-text volume-info-description"> Abstract: A deep understanding on the intermixing of components in hybrid yarn or composite structures is decisive in order to develop hybrid structures with desired properties. This paper presents the development of a versatile procedure for the determination of the degree of fiber mixing in yarns and composites based on microscopy images auto-segmented by a neural network. The procedure is based on the quantification of blend irregularity values and blend homogeneity. For this purpose, functions of spatial point patterns analysis have been used to investigate the blend uniformity of yarn and composite cross sectional areas. The results show that the trained neural network model for segmentation of images has an accuracy of 92 %, indicating that the method is capable of accurately assessing the location of fibers in hybrid struc-tures. The results of the spatial point patterns analysis reveals a correlation between the blend value and the properties of yarns and composites. The proposed method provides a fast and reliable way to evaluate the hybrid structures, which could be used as a tool for quality control and process optimization. </div> <div> <a data-readmore="{ block: '#abstractTextBlock601580', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 149 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 11 to 20 of 21 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="PagedList-skipToPrevious"><a href="/KEM.978" rel="prev"><</a></li><li><a href="/KEM.978">1</a></li><li class="active"><span>2</span></li><li><a href="/KEM.978/3">3</a></li><li class="PagedList-skipToNext"><a href="/KEM.978/3" 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="/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.
