Abstract Defect‐engineering is a viable strategy to improve the activity of nanocatalysts for oxygen evolution reaction (OER), whose slow kinetics still strongly limits broad market penetration electrochemical water splitting as sustainable technology large‐scale hydrogen production. High‐entropy spinel oxides (HESOs) are in focus due their great potential low‐cost OER electrocatalysts. In this work, electrospun HESO nanofibers (NFs), based on (Cr,Mn,Fe,Co,Ni), (Cr,Mn,Fe,Co,Zn) and...
High-entropy oxides (HEOs) have emerged as promising anode materials for next-generation lithium-ion batteries (LIBs). Among them, spinel HEOs with vacant lattice sites allowing lithium insertion and diffusion seem particularly attractive. In this work, electrospun oxygen-deficient (Mn,Fe,Co,Ni,Zn) HEO nanofibers are produced under environmentally friendly calcination conditions evaluated active material in LIBs.

The sodium-ion battery (Na-ion battery, NIB) is considered the most promising post-lithium energy storage technology, taking advantage of using same manufacturing technology as Li-ion batteries (LIBs), while enabling use more abundant and economic, thus sustainable, raw materials. Due to inability Na+ ions be intercalated within graphene-layered structure graphite-based electrodes (the state art anode material in LIBs), highly disordered microporous carbons, known hard are choice for NIB...

Unlike conventional alloys, where carbon content typically promotes carbide compound formation and reduces localized corrosion resistance, the impact of in additively manufactured materials remains largely unexplored due to rapid cooling rates inhibiting formation. This study addresses novel question whether reducing benefits performance its underlying mechanisms Ni-Fe-Cr-based alloy 718. Employing high-resolution techniques microcapillary electrochemical methods, it was revealed that higher...

The phase diagram reveals presence four thermal transitions strongly depend salt content. High-level density functional theory (DFT)-based electronic structure calculations substantiate structural...
High-entropy oxide nanofibers, based on equimolar (Cr,Mn,Fe,Co,Ni), (Cr,Mn,Fe,Co,Zn) and (Cr,Mn,Fe,Ni,Zn) combinations, were prepared by electrospinning followed calcination.
