defects, using scanning surface inspection systems (SSIS) is of paramount importance because it provides the opportunity to determine the root causes of defects, which is valuable for yield enhancement. This report presents a novel defect classification approach developed by optimizing the linear-based channeling (LBC) and rule-based binning (RBB) algorithms that are applied to a commercially available SSIS (KLA-SP5), in combination with test sample selection including the signature defect patterns associated with the typical crystal growth process. The experimental results demonstrate that defect classification is possible with an accuracy and purity above 80% using the LBC algorithm and 90% using the RBB algorithm. </div> <div> <a data-readmore="{ block: '#abstractTextBlock581545', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.11">Design and Numerical Simulation of Color Tunable Laterally Arranged Quantum well Light Emitting Diode with Double Anode Single Cathode</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Ahmid Djelloul, Hamaizia Zahra </div> </div> <div id="abstractTextBlock568150" class="volume-info volume-info-text volume-info-description"> Abstract: In this paper, a color-tunable light emitting diode LED with two laterally arranged single quantum wells (SQWs) is designed, and simulated. In this work, III-nitride materials are used. The structure has been numerically investigated using the ATLAS simulation software. The proposed structure has three electrodes. This gives the opportunity to emit violet (420 nm) or green (560 nm) light individually. Furthermore, it can emit simultaneously a mixture of both colors, and at a certain mixture ratio the white light is obtained with chromaticity coordinates ( x = 0.3113, y = 0.3973). The lateral arrangement of the two SQWs reduces the negative effect of photon absorption; which will give good external quantum efficiency (EQE). The structure has a big importance in the application of the solid-state lighting, especially in the white light generation. </div> <div> <a data-readmore="{ block: '#abstractTextBlock568150', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.25">Defect Evolution in Laser Remelting of Thermally Sprayed Cr<sub>3</sub>C<sub>2</sub>-NiCr Cermet Coating</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: En Wei Qin, Hai Feng Lu, Wen Li Li, Hong Zhuan Qin, Chen Yang Pan, Shu Hui Wu </div> </div> <div id="abstractTextBlock586128" class="volume-info volume-info-text volume-info-description"> Abstract: Pores and weak bonding are the inherently drawbacks for thermally sprayed coating. Laser beam is an attractive approach to remelt thermal spray coating for obtaining fully dense coating with metallurgical bonding with substrate. However, defects of holes or cracks are highly inevitable with unmatching remelting processing parameters. In this work, a thermally sprayed Cr<sub>3</sub>C<sub>2</sub>-NiCr cermet coating by high velocity oxygen fuel spraying was post-processed by laser remelting with a series of varying beam energy densities from 37.5 J/mm<sup>2</sup> to 225 J/mm<sup>2</sup>. The defect evolution was investigated by both experimental and numerical simulation methods. Large holes and through-thickness cracks were typical defects observed in the remelt coating by optical microscopy. The experimental results show that remelting-induced defects evolve into three stages with laser energy density. The effect of energy density on remelt structure was further verified with the temperature field by numerical simulation with ABAQUS code. The stress field interpreted the crack formation at periodical formation sites. The results on the defect evolution shed light on obtaining functional coatings for industrial applications. </div> <div> <a data-readmore="{ block: '#abstractTextBlock586128', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 25 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.39">Corrosion Behavior of 7A52 Aluminum Alloy Plasma Arc Welding Joint in Simulated Marine Atmosphere Environment</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Yu Xin Liu, Zhe Sun, Dong Yu He, Jian Jun Lin, Kai Bo Wang, Xuan Zhao, Yao Hui Lv </div> </div> <div id="abstractTextBlock561870" class="volume-info volume-info-text volume-info-description"> Abstract: Corrosion behavior of 7A52 aluminum alloy plasma arc welding (PAW) joint was investigated in simulation of marine atmosphere environment with salt water spray test.

Hossein Sehhat, Mohammadjafar Hadad </div> </div> <div id="abstractTextBlock583462" class="volume-info volume-info-text volume-info-description"> Abstract: One of the most important factors influencing the quality of the weld created by the micro friction stir welding is the amount of heat generated during the welding operation. Due to the lack of proper mixing of materials at low temperatures, joints' quality decreases due to the formation of cold welds. Also, overheating takes the process out of solid-state welding, which prevents good joints. Finite element analysis of friction stir welding leads to a better understanding of the effect of different parameters on the process. With the results extracted from such analysis, some of the output can be predicted, such as heat distribution. In the present study, in order to perform finite element analysis of the micro friction stir welding of Al 1050 to pure copper, the coupled Eulerian-Lagrangian method in Abaqus software has been used. The results of finite element analysis showed that the heat distribution on the copper side is wider due to the higher heat transfer coefficient of copper than aluminum. The maximum temperature in the analysis was recorded in the weld line, which was 392°C. The heat generated during the welding process was measured at different points relative to the joint line, and appropriate matching was observed with a comparison of experiments and simulation results. </div> <div> <a data-readmore="{ block: '#abstractTextBlock583462', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 49 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.61">Mechanical Behaviour, Properties and Characteristics of Foamed Cellular Concrete: A Review</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Facundo Atuel Retamal, Viviana Carolina Rougier </div> </div> <div id="abstractTextBlock583673" class="volume-info volume-info-text volume-info-description"> Abstract: Foamed cellular concrete (FCC) is a type of lightweight concrete. Traditionally, it has been used for insulation and void filling. However, in the last years, the possibility of obtaining high strength FCC has motivated the study of its structural use. The novelty and uniqueness of this article is to provide a review of the most important aspect of FCC including component materials, design and mix elaboration, physical properties and mainly, its mechanical behaviour. Also, in order to achieve a global understanding of the material and its characteristics, advances regarding its physical properties are collected: density, porosity, thermal, acoustic and water insulation, durability, fire resistance and drying shrinkage. Then mechanical properties such as elastic modulus, compressive, tensile, bending and shear behaviour, are analysed. The literature review also aims to evaluate the influence of using inert and active mineral additions, fibers and chemical additives to improve its mechanical and physical properties. Based on the work done, research needs have been identified: there are no prediction models for stress-strain behaviour with complete curves for FCC in compression nor in traction, the performed numerical modelling is scarce, use and effect of chemical additives is a not far studied, long-term tests are scarce or nil, the evaluation of resistance in different aggressive environments has not been sufficiently evaluated. </div> <div> <a data-readmore="{ block: '#abstractTextBlock583673', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 61 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.87">Structure, Property, Processing and Applications of Fire Retardant Materials: A Brief Review</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Sravan Bokka, Srungarpu Nagabhusan Achary, Anirban Chowdhury </div> </div> <div id="abstractTextBlock582151" class="volume-info volume-info-text volume-info-description"> Abstract: Fire though an important component of life, the devastating effect of fire accidents is a threat to life and materials. Thus, the prevention and control of fire are becoming a serious concern. Hence, it is no wonder that fire retardant materials (FRMs) are slowly becoming ubiquitous in our daily lives. To control the fire in an unexpected fire accident or to prevent fire accidents FRMs are becoming essential requirements. To save material or life, fire retardant materials have been used for long knowingly or unknowingly. However, the understandings of chemistry and thermochemistry of materials helped for the development of efficient FRMs. Diversified materials, processing methods, and application modes have been developed, and all of them become specific depending on the nature and origin of the fire. In this regard, the inorganic FRMs form a distinct category due to their low cost, easier processing and wider choice of application mode without leaving any additional environmental burden either to land or the atmosphere. In this paper, different fire retardant materials and their properties with the abilities to tackle the fire at different temperatures are reviewed. The primary characteristics of fire and the thermal behaviours of FRMs as well as changes in behaviour/properties when FRMs are treated with certain synergistic systems are discussed. The importance of composition, morphology and structure of FRMs on the efficiency and applicability are discussed. Recent developments on the synthesis and characterisation of different types of FRMs and their composites have been elaborated. The effective applications and the commercial products based on their properties are also briefly covered. Overall, the review provides an overview of existing information on fire retardant materials in terms of their synthesis, processing, usability and limitations, with a prime attention on the process-structure-property relations of these materials. </div> <div> <a data-readmore="{ block: '#abstractTextBlock582151', 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="/AMR.1170.117">Study of the Mechanical Properties of Sugar Cane Fiber for Packaging Paper Based on Polyacrylamide and Natural Fibers</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Danielle Ferreira dos Santos, Artur Junger Vasconcelos </div> </div> <div id="abstractTextBlock580647" class="volume-info volume-info-text volume-info-description"> Abstract: Natural fibers have been extensively studied as a reinforcement filler in obtaining composites, replacing partially synthetic fibers. The vast majority of these materials originate from agro-industrial waste with a high content of lignin and cellulose making it a very interesting material with low cost and good mechanical properties. The purpose of the study was to obtain a composite based on alkyl ketene dimer resin, for the manufacture of sustainable packaging, made of paper by adding a 10% (w/w) con-tent of green coconut fiber and sugarcane bagasse fiber, and evaluated the impact of the filler on the mechanical behavior of the systems. The studied material was characterized from mechanical tests, such as Ring Crush Test (RCT) and Concora Medium Test (CMT) evaluating the maximum resistance supported by centimeter in the pre-pared composites, by the specimens. Through the RCT tests, with 10% w/w fibers, it was possible to verify that the fiber from sugarcane bagasse reached an increase of about 1% in the reinforcement effect compared to pure paper, and a difference of up to 2% in strength mechanics in relation to coir fiber, and CMT tests shows the reinforcement effect of the presence of sugarcane bagasse fiber, with an increase of about 3% compared to pure paper, and with a mechanical strength higher by 1% compared to coconut fiber. Therefore, the study was funneled with sugar cane fiber, varying the content by 20 and 30 % (w/w), evaluating the impact on the dispersion of this filler in the polymeric matrix and, consequently, the mechanical response of the composite with these compositions. The conclusion of the study was that the system prepared with 20% (w/w) was the one that achieved the greatest optimization of the mechanical properties, evaluated by the tests. This type of material can be applied to obtain cardboard boxes with resistance to high loads, due to the achievement of good mechanical properties. </div> <div> <a data-readmore="{ block: '#abstractTextBlock580647', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 117 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.129">Chemical Composition and Morphological Characterization of Enset (<i>E. ventricosum</i>) Leaf Residues for Paper Pulping Production: Kraft Pulping</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Emiru Yidnekachew Melesse, Zelelam Belay Asrat </div> </div> <div id="abstractTextBlock575313" class="volume-info volume-info-text volume-info-description"> Abstract: Currently, paper pulping production from woody materials has many disadvantages due to its high energy, chemical, water consumption, methane emissions, and deforestation. However, the use of non-woody materials solves these problems. This study focused on the use of non-virgin raw material (Enset leaf fiber) in pulp and paper making. Enset leaf residues are the primary solid residues after the steam plant is used for “Kocho” processing. This leaf fiber has a lignocellulose component, converting this residue into Pulp and paper is crucial in terms of economic and waste management via the Kraft process. It has a higher fiber quality, lower energy consumption, and high recoverability of the chemical raw materials used in the process. The chemical composition of the Enset leaf fiber was analyzed using the Technical Association of Pulp and Paper. It has an excellent fiber length (2.12±1.46mm), fiber diameter (26.55±15.6µm) and<i> </i>acceptable rigidity coefficient (1.05±0.07), and flexibility coefficient (125.23±0.04). The maximum pulp yield was obtained at a temperature of 120°C, NaOH concentration of 8%, and 40 min cooking time off, which was 69.92% w/w. The functional groups of the Enset leaf fiber and morphological characteristics of the fiber were investigated. </div> <div> <a data-readmore="{ block: '#abstractTextBlock575313', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 129 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMR.1170.141">Sequestration of Arsenate from Surface Water Using Chemically Activated Carbon of Black Velvet Tamarind Fruit Shell</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Ahmad Abdurrazzaq, Haruna Musa, Umar Sani </div> </div> <div id="abstractTextBlock567079" class="volume-info volume-info-text volume-info-description"> Abstract: Chemically activated carbon of BVT fruit shell was investigated for its potential adsorption functionalities to remove As (V) from surface water in a batch system. The AC showed maximum removal efficiency of approximately 75% depicting Q<sub>max</sub> of 0.00018mg/g at an initial sorbate concentration of 0.016mg/L, a contact time of 26min, and a carbon dosage of 1g. The sorption isotherm studies revealed a better fit for Langmuir isotherm. Hence, a homogeneous monolayer surface adsorption process has taken place. </div> <div> <a data-readmore="{ block: '#abstractTextBlock567079', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 141 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 11 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/AMR.1170/2">2</a></li><li class="PagedList-skipToNext"><a href="/AMR.1170/2" 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.
