Design and development of (Ti, Zr, Hf)-Al based medium entropy alloys and high entropy alloys

Materials Chemistry and Physics, 2022
Abstract The design and development of TiZrHfAl medium entropy alloy (MEA), and the TiZrHfAlNb0.2 and TiZrHfAlV0.2 high entropy alloys (HEAs) is described. The combination of 4th subgroup elements (Ti, Zr, and Hf) with Al is discussed based on the periodic table and taxonomy of HEAs. The alloys were designed using alloy parameters for HEAs, predicted

Nobel Metal Based High Entropy Alloy for Conversion of Carbon Dioxide (CO2) to Hydrocarbon [PDF]

, 2019
Conversion of carbon-di-oxide into selective hydrocarbon using stable catalyst remains a holy-grail in catalysis community. The high overpotential, stability, and selectivity in use of a single metal-based catalyst still remain a challenge.

Cantor-derived medium-entropy alloys: bridging the gap between traditional metallic and high-entropy alloys

Journal of Materials Research and Technology, 2022
The year 2004 marked the beginning of a new era in the design of metallic materials, as the concept of multiple principal component alloys, commonly known as High-Entropy Alloys (HEAs), was proposed by Cantor and Yeh. The unexpected single-phase microstructure, instead of the expected brittle intermetallic compounds, was attributed to the large entropy

Advances in High-Entropy Alloys’ Microstructure, Properties and Preparation

Metals
High-entropy alloys (HEAs), medium-entropy alloys (MEAs), and related multi-principal-element materials have significantly broadened the conceptual framework of alloy design by moving beyond conventional alloy systems centered on one principal element [..

Coexistence of two types of short-range order in Si–Ge–Sn medium-entropy alloys

Communications Materials, 2022
Short-range chemical ordering has emerged as a key feature for controlling the properties of high-entropy alloys. Here, ab initio calculations reveal that two types of short-range ordering exist in Si–Ge–Sn medium-entropy alloys, suggesting that multiple

High entropy alloy nanoparticle formation at low temperatures [PDF]

, 2022
Entropy-driven formation of high entropy alloy (HEA) nanoparticles from metal precursors requires high temperatures and controlled cooling rates. However, several proposed HEA nanoparticle synthesis strategies avoid the high-temperature regime.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...
