Design of Multiphase Compositionally Complex Alloys for Enhanced Hardness at Elevated Temperatures and Machinability: Comparative Study with Inconel 718

open access: yesAdvanced Engineering Materials, EarlyView.
This study compares the mechanical properties of Inconel 718 with two newly developed compositionally complex alloys (CCAs). Inco‐like‐H alloy demonstrates significantly improved wear resistance, surface finish, and hardness, notably at high temperatures. This CCA requires no heat treatment and is well suited for additive manufacturing. Its performance

LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

open access: yesAdvanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.

Advances in Understanding of the Application of Unit Operations in Metallurgy of Rare Earth Elements

open access: yesMetals, 2021
Unit operations (UO) are mostly used in non-ferrous extractive metallurgy (NFEM) and usually separated into three categories: (1) hydrometallurgy (leaching under atmospheric and high pressure conditions, mixing of solution with gas and mechanical parts ...

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu

open access: yesAdvanced Functional Materials, EarlyView.
From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).
