The development of advanced bifunctional oxygen electrocatalysts for oxygen reduction and evolution reactions(ORR and OER) is critical to the practical application of zinc-air batteries(ZABs). Herein, a silica-assisted method is reported to integrate numerous accessible edge Fe-Nx sites into porous graphitic carbon(named Fe-N-G) for achieving highly active and robust oxygen electrocatalysis. Silica facilitates the formation of edge Fe-Nx sites and dense graphitic domains in carbon by inhibiting iron *** purification process creates a well-developed mass transfer channel for Fe-N-G. Consequently,Fe-N-G delivers a half-wave potential of 0.859 V in ORR and an overpotential of 344 m V at10 m A cm^(-2)in OER. During long-term operation, the graphitic layers protect edge Fe-Nx sites from demetallation in ORR and synergize with Fe OOH species endowing Fe-N-G with enhanced OER *** functional theory calculations reveal that the edge Fe-Nx site is superior to the in-plane Fe-Nx site in terms of OH* dissociation in ORR and OOH* formation in OER. The constructed ZAB based on Fe-N-G cathode shows a higher peak power density of 133 m W cm^(-2)and more stable cycling performance than Pt/C + RuO2counterparts. This work provides a novel strategy to obtain high-efficiency bifunctional oxygen electrocatalysts through space mediation.

作者： Mohamad Faizul Yahya Jamil Salleh Wan Yunus Wan Ahmad Textile Technology Program Faculty of Applied Sciences Universiti Teknologi Mara Shah Alam Selangor Malaysia

The article presents an extensive experimental test and finite element simulation of plain 1/1 woven fabric subjected to uniaxial loading. Square woven fabric is configured to allow systematic investigation of weave effects under uniaxial tensile load. The geometric fabrics models consisting of warp and weft yarns are imported to finite element analysis package, ABAQUS, for mechanical performance simulation. Simulated and experimental stress-strain validation of plain is reported to have strong positive correlation of 0.9986 and 0.999 in warp and weft direction, respectively. Further analysis is performed on the validated models such as stress distribution groups and maximum stress regions.

IEEE Colloquium on Humanities, Science and Engineering (CHUSER)

The study aims to establish significant fabric and thread mechanical properties that influence seam strength sewn with different parameters using Structural Equation Modeling (SEM). Fabrics were tested for their mechanical properties using Kawabata Evaluation System (KES) and Fabric Assurance for Simple Test (FAST). Seam was constructed using different types of threads, stitches and needles. It was found that SEM was able to identify the thread and fabric mechanical properties that highly correlated with the seam strength. The selection of these properties gives the apparel manufacture guideline on the best selection of sewing parameters to achieve minimum failure of the seam.

This paper presents a comprehensive review on the current state of digital simulation technology and its strategic application usages with a key focus on advanced compression garments. Although three-dimensional(3D) digital garment simulators have significantly impacted the apparel and textile industry, their use has been limited to visual prototyping, quality checking, or marketing. The physical properties of garment simulators have been overlooked in advanced functional manufacturing. This literature review investigates the possibility of strategically utilizing virtual physical properties to enhance garment functions, specifically in wearables and medical-grade compression fields. The first phase of this paper gives an overview of the current state of 3D garment simulation tools and their measurement features. This is followed by a gap analysis between simulated and physical property evaluations, focusing on minimizing the gaps. The literature is thoroughly examined to identify appropriate studies that uses digital tools for compressional garments and add value to wearables and healthcare applications. This paper provides valuable insights for apparel and textile engineers, enabling them to better understand the limitations and capabilities of garment simulators in improving advanced features for specific end users.

Separators have an important influence on the safety and performance of lithium-ion batteries (LIBs). However, traditional polyolefin-based separators suffer from poor thermal stability and weak electrolyte wettability. Here, by using hydroxyapatite (HAP) and cellulose nanofibers (CNFs) as raw materials, we fabricated a unique HAP/CNF hybrid separator. The separators exhibit excellent thermal properties, with high thermal stability (up to 250 °C) and outstanding flame retardancy. The separators also demonstrate excellent electrolyte wettability. Compared to polypropylene (PP) separators, the HAP/CNF separators show a smaller contact angle with electrolytes, 17.2° for HAP/CNF and 45.5° for PP. Meanwhile, the HAP/CNF separators illustrate an excellent smoothness of 68.0 nm. In addition, the batteries assembled with the hybrid separators display a better performance compared with the batteries assembled with commercial PP separators. The raw materials are green, and the fabrication processes are free of organic solvents. We envision that the HAP/CNF hybrid separator could be a promising separator candidate for next-generation high-safety and high-performance LIBs. © 2023 American Chemical Society.

This paper discusses the actuation durability of a conducting shape memory polyurethane (CSMPU) actuator. Introduced in 2004, the CSMPU actuator was manufactured by an in situ polymerization method for shape memory polyurethane with multiwalled carbon nanotubes. In order to apply the CSMPU to smart actuators and determine detailed design concepts, the durability data should be measured. Hence, the experiments in this research were designed to obtain durability data, and the maximum number of actuation cycles versus the initial elongation ratio and the actuation temperature were measured for the purpose of assessing durability. The broken surfaces of the specimens were investigated.

Influence of surface coating on grip comfort of leather steering wheel

Journal of textile Engineering 2011年第6期57卷 139-144页

We investigated how the surface coating of leathers influenced 'touch feeling' and 'grip comfort' of leather steering wheels. Four leather sheets coated by different urethane coating materials and four steering wheels covered by these leathers were used as samples. Both 'touch feeling' of the leather sheets and 'grip comfort' of the steering wheels were evaluated by the paired comparison method. Then each mean preference score of 'touch feeling' and 'grip comfort' was examined by the principal component analysis. From the result, it was found that 'moisture' and 'smoothness' were identified as principal factors of 'touch feeling' and 'grip comfort'. And the physical properties (i.e. compression, friction, surface roughness, and q-max) of the leather sheets were measured. The relationship between the subjective evaluation (i.e. 'touch feeling' and 'grip comfort') and these measured physical properties were investigated. From the result, it was found that 'moisture' was correlated significantly with 'MIU/MMD' (MIU: mean coefficient of friction, MMD: mean deviation of MIU) and 'dry' was correlated significantly with 'Ra' (arithmetic mean deviation of the roughness profile). The measuring method of the physical properties was viable approach for the quantitative evaluation of 'grip comfort'. © 2011 The textile Machinery Society of Japan.
