State-of-the-art carbonaceous anodes are approaching their achievable performance limit in Li-ion batteries (LIBs). Silicon has been recognized as one of the most promising for next-generation LIBs because its advantageous specific capacity and secure working potential. However, practical implementation silicon needs to overcome challenges substantial volume changes, intrinsic low conductivity, unstable solid electrolyte interphase (SEI) films. Here, we report an inventive design a sandwich...
Intermetallic compounds formed from non-precious transition metals are promising cost-effective and robust catalysts for electrochemical hydrogen production. However, the development of monolithic nanoporous intermetallics, with ample active sites sufficient electrocatalytic activity, remains a challenge. Here we report fabrication Co7Mo6 Fe7Mo6 intermetallic via liquid metal dealloying. Along three-dimensional bicontinuous open porosity, high-temperature dealloying overcomes kinetic energy...
Dislocations are the intrinsic origin of crystal plasticity. However, initial high-density dislocations in work-hardened materials commonly asserted to be detrimental ductility according textbook strengthening theory. Inspired by self-organized critical states non-equilibrium complex systems nature, we explored mechanical response an additively manufactured medium entropy alloy with segregation-dislocation structures (SD-SOS). We show here that when form SD-SOS, theory dislocation hardening...
Recently-developed high-entropy alloys (HEAs) containing multiple principal metallic elements have extended the compositional space of solid solutions and range their mechanical properties. Here we show that realm possibilities can be further expanded through substituting constituent metals with metalloids, which are desirable for tailoring strength/ductility because they chemical interactions atomic sizes distinctly different from host elements. Specifically, metalloid substitution...
The equiatomic CoCrFeMnNi Cantor alloy, a face-centered-cubic (FCC) single-phase high-entropy alloy (HEA), has attracted considerable attention owing to its high strength and good ductility over wide temperature range. mechanical performance of this was improved by reducing the stacking fault energy (SFE) through composition modification, thus, series near- or non-equiatomic HEAs that are stronger more ductile than their predecessor have been developed. However, plastic-deformation behavior...
A high-priority target in the design of new metallic materials for load-bearing implant applications is reduction Young's modulus approximating that cortical bone predominant loading direction. Here, we explore how directionally preferential bulk elastic properties are achieved by harnessing anisotropy. Specifically focusing on recently proposed biocompatible refractory high-entropy alloys (RHEAs) body-centered cubic structure, conduct systematic density-functional theory calculations to...
Owing to their attractive structure and mechanical properties, high-entropy alloys (HEAs) medium-entropy (MEAs) have attracted considerable research interest. The strength of HEAs/MEAs with a single face-centered cubic (FCC) phase, on the other hand, requires improvement. Therefore, in this study, we demonstrate strategy for increasing room-temperature FCC-phase by tuning cryo-pre-straining-induced crystal defects via temperature-dependent stacking fault energy-regulated plasticity...
