Self-regeneration of supported transition metals by a high entropy-driven principle

Nature Communications, 2021
Sintering of supported transition metal catalysts is problematic for high-temperature catalysis. Here the authors report entropy-driven, self-regeneration of high entropy oxide nanoparticles, promoting better stability and in situ reversible exsolution ...

Entropy splitting for high-order numerical simulation of compressible turbulence [PDF]

, 2002
A stable high-order numerical scheme for direct numerical simulation (DNS) of shock-free compressible turbulence is presented. The method is applicable to general geometries. It contains no upwinding, artificial dissipation, or filtering.

High entropy oxides for reversible energy storage [PDF]

Nature Communications, 2018
AbstractIn recent years, the concept of entropy stabilization of crystal structures in oxide systems has led to an increased research activity in the field of “high entropy oxides”. These compounds comprise the incorporation of multiple metal cations into single-phase crystal structures and interactions among the various metal cations leading to ...

Study on tribological oxide mechanism of CoCrFeNiMo high entropy alloy [PDF]

, 2023
The oxide film can improve the tribological properties of high entropy alloy, but its formation needs further study. In this work, the tribological oxide mechanism of CoCrFeNiMo high entropy alloys was investigated by means of experiments and finite ...

Entropy-stabilized single-atom Pd catalysts via high-entropy fluorite oxide supports

Nature Communications, 2020
Fabricating intrinsically stable single-atom catalysts (SACs) on traditional supports remains a formidable challenge in catalysis. Here, the authors propose a new strategy to construct a sintering-resistant Pd SAC on a novel equimolar high-entropy ...

High Temperature Oxidation and Corrosion Properties of High Entropy Superalloys [PDF]

Entropy, 2016
The present work investigates the high temperature oxidation and corrosion behaviour of high entropy superalloys (HESA). A high content of various solutes in HESA leads to formation of complex oxides, however the Cr and Al activities of HESA are sufficient to promote protective chromia or alumina formation on the surface. By comparing the oxidation and

High‐Entropy Oxides: Fundamental Aspects and Electrochemical Properties [PDF]

Advanced Materials, 2019
AbstractHigh‐entropy materials, especially high‐entropy alloys and oxides, have gained significant interest over the years due to their unique structural characteristics and correlated possibilities for tailoring of functional properties. The developments in the area of high‐entropy oxides are highlighted here, with emphasis placed on their fundamental

Effect of DFPP on Ferroptosis in Peripheral Blood CD14+ Monocytes of Hyperlipidemic Patients Involving the ACSL4/LPCAT3/ALOX5 Pathway

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Hyperlipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD). Although statins are the cornerstone of lipid‐lowering therapy, their use may be limited in some patients by adverse effects. This study evaluated the possible impact of non‐drug treatment using double‐filtration plasmapheresis (DFPP) on CD14+
