Versatile Magneto‐Dielectric Response of Epitaxial Thin Films of the High Entropy Oxide Perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3

Advanced Materials, EarlyView.
The magnetic high entropy oxide perovskite Nd(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 exhibits a substantially large dielectric constant (εr) at room temperature, which shows distinct anionic and cationic contributions in the form of zero and finite bias peaks, respectively, down to its magnetic transition temperature (Tmag).

Effective coupling of rapid freeze-quench to high-frequency electron paramagnetic resonance.

PLoS ONE, 2020
We report an easy, efficient and reproducible way to prepare Rapid-Freeze-Quench samples in sub-millimeter capillaries and load these into the probe head of a 275 GHz Electron Paramagnetic Resonance spectrometer.

Visualizing electron pockets in cuprate superconductors

, 2012
Fingerprint of the electron-pocket in cuprates has been obtained only in numerous magneto-transport measurements, but its absence in spectroscopic observations pose a long-standing mystery. We develop a theoretical tool to provide ways to detect electron-

Entropy‐Driven Spin Transition in Rare Earth Perovskites Enables Feedback Adsorption for Enhanced Acidic Water Oxidation

Advanced Materials, EarlyView.
A synthetic protocol for fabricating high‐entropy rare earth perovskite oxides with abundant lattice distortions and oxygen vacancies has been developed, representing an emerging platform for anchoring RuO2. High entropy strategy significantly modulated the electronic structures and spin states, inducing a shift in the mechanism from the adsorption ...

Collective character of spin excitations in a system of Mn$^{2+}$ spins coupled to a two-dimensional electron gas

, 2003
We have studied the low energy spin excitations in n-type CdMnTe based dilute magnetic semiconductor quantum wells. For magnetic fields for which the energies for the excitation of free carriers and Mn spins are almost identical an anomalously large ...

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

Advanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Backbone Engineering of Carbon‐Centered NHC‐Derived Diradicals: From Electronic State Tuning to High‐Performance Organic Field‐Effect Transistors

Advanced Materials, EarlyView.
The open‐shell nature of diradicals facilitates charge separation, and compounds with moderate diradical character demonstrate remarkable potential in organic field‐effect transistors (OFET) applications due to their low reorganization energies for hole and electron transport.

The nature of CuA in cytochrome c oxidase [PDF]

, 1982
The isolation and purification of yeast cytochrome c oxidase is described. Characterization of the purified protein indicates that it is spectroscopically identical with cytochrome c oxidase isolated from beef heart.
