The deployment of hydrogen as an energy carrier is found to be a vital alternative fuel for the future. It expected that water electrolysis, powered by renewable sources, able scale‐up production. However, reaction kinetic oxygen evolution (OER) sluggish process, which predominantly limits efficiency electrolysis. This review recapitulates recent progress and efforts made in design development ...

Three-dimensional (3D) printing with wood-plastic composites is already well known, and the use of wood in four-dimensional (4D) being increasingly explored. 4D an evolving area additive technologies where, appropriate design 3D materials, we can create products that change shape form dynamic structures when triggered externally. In printing, hygroscopicity – usually considered a disadvantage b...

Multilayer composites have recently attracted considerable attention due to their ability take advantage of the benefits various metallic materials simultaneously. The present study is first use parallel tubular channel angular pressing (PTCAP) as a severe plastic deformation method fabricate bimetal Al/Mg tube. This process was applied on commercially pure aluminum along with an AM60 magnesium...

Solid-state dissimilar bi- or multi-metallic bonding is promising for achieving lightweight multifunctional components in automotive, nuclear power and aerospace industries. To understand how to achieve a high-quality interface between materials, aluminium alloy (Al)–steel (Fe) bimetal gears manufactured under hot forge were systematically investigated. In this work, comprehensive analyses of m...

With lead-free legislation impacting printed circuit board (PCB) manufacturing, immersion silver (ImAg) finish is adapted as the top finish of copper trace on PCB due to its many advantages. However, it is easy for silver to form electrochemical migration (ECM) in high humid environment, so that the potential bias and spacing between adjacent circuits are limited. In addition, since the thickne...

Multilayered solid structures made of isotropic, transversely isotropic, or general anisotropic materials are frequently used in aerospace, mechanical, and civil structures. Ultrasonic fields developed in such structures by finite size transducers simulating actual experiments in laboratories or in the field have not been rigorously studied. Several attempts to compute the ultrasonic field insi...

A low-cost and high effective copper/aluminum (Cu/Al) bimetal has been developed for treatments of halogenated methanes, including dichloromethane, in near neutral and high pH aqueous systems. Bimetallic Cu/Al was prepared by a simple two-step synthetic method where Cu was deposited onto the Al surface. The presence of Cu on Al significantly enhanced rates of degradation of halogenated methanes...
