Dinuclear Copper(I) Complexes Supported by Bis‐Tridentate N‐Donor‐Ligands: Turning‐On Tyrosinase Activity

European Journal of Inorganic Chemistry, Volume 2022, Issue 35, December 16, 2022., 2022
Dinuclear copper(I) complexes supported by bis‐tridentate N‐donor ligands with two imine functions mediate the conversion of a monophenol to its corresponding o‐quinone, in contrast to analogous complexes supported by ligands with amine functions. Abstract Four structurally related bis‐tridentate N‐donor ligands with either two secondary amine or two ...

Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

Advanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Weak Antiferromagnetic Order in Anisotropic Quantum Pyrochlores [PDF]

arXiv, 2008
We study the ground state properties of an anisotropic, quasi-2D version of the quantum (S=1/2) pyrochlore antiferromagnet. In the presence of Dzyaloshinsky-Moriya interactions, in addition to the Heisenberg exchanges, it is shown that two types of ordered magnetic states are generally possible: non coplanar "chiral," and coplanar antiferromagnetic ...

Ultra‐High Temperature Calcination of Crystalline α‐Fe2O3 and Its Nonlinear Optical Properties for Ultrafast Photonics

Advanced Science, EarlyView.
This study focuses on exploring the nonlinear optical properties of α‐Fe2O3 material calcined at ultra‐high temperatures. It is discovered that the α‐Fe2O3 material underwent the phase transition at ultra‐high temperatures. Then, the α‐Fe2O3 material calcined at 1100 °C is successfully integrated as a saturable absorber into an erbium‐doped fiber laser,

Topological antiferromagnetic spintronics: Part of a collection of reviews on antiferromagnetic spintronics [PDF]

arXiv, 2017
The recent demonstrations of electrical manipulation and detection of antiferromagnetic spins have opened up a chapter in the spintronics story. In this article, we review the emerging research field that is exploring synergies between antiferromagnetic spintronics and topological structures in real and momentum space.

Unusual Thermal Transport in Few‐Layer Van der Waals Antiferromagnet CrOCl

Advanced Science, EarlyView.
Thermal transport serves as an ultra‐sensitive probe for detecting the magnetic order in 2D materials. Using the suspended thermal bridge method enhanced by Wheatstone bridges, it is, for the first time, observed anomalous critical behavior in few‐layer CrOCl near its Néel temperature.

Mechanism of ammonia oxidation to dinitrogen, nitrite, and nitrate on β‐Ni(OH)2 from first‐principles simulations

Electrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract The electrocatalyzed ammonia oxidation reaction (AOR) is a potential pathway toward waste ammonia remediation, energy generation, and the synthesis of value‐added products. To date, mechanistic studies have focused on elucidating the progress of AOR on Pt‐based catalysts with an established pathway for N2$\mathrm{N_2}$ only.
