Reconstruction-induced NiCu-based Catalysts towards Paired Electrochemical Refining
Shanlin Li,Pei-Long Ma,Chunlang Gao,Lijia Liu,Xunlu Wang,Mohsen Shakour,Roman Chernikov,Kaiwen Wang,Danmin Liu,Ruguang Ma,Jiacheng Wang +10 more
TL;DR: A paired electrochemical refinery toward cathodic nitrate reduction reaction (NO3RR) and anodic glycerol oxidation reaction (GOR) driven by renewable electricity could generate high value-added ammonia and formic acid, simultaneously as discussed by the authors .

Fluorite-pyrochlore phase transition in nanostructured Ln2Hf2O7 (Ln = La-Lu)
V. V. Popov,Alexey P. Menushenkov,Alexander Yaroslavtsev,Alexander Yaroslavtsev,Ya. V. Zubavichus,B. R. Gaynanov,A. A. Yastrebtsev,Denis Leshchev,Roman Chernikov +8 more
TL;DR: In this article, the authors studied the whole process of the crystal and local atomic structure realignment during the crystallization and the phase transition in the series of Ln 2 Hf 2 O 7 (Ln-=-La-Lu) samples synthesized by the coprecipitation method with the subsequent annealing of mixed hydroxides (precursors).

A Transition from Localized to Strongly Correlated Electron Behavior and Mixed Valence Driven by Physical or Chemical Pressure in ACo2As2 (A = Eu and Ca).
Xiaoyan Tan,Gilberto Fabbris,Gilberto Fabbris,Daniel Haskel,Alexander Yaroslavtsev,Alexander Yaroslavtsev,Huibo Cao,Corey M. Thompson,Kirill Kovnir,Alexey P. Menushenkov,Roman Chernikov,V. Ovidiu Garlea,Michael Shatruk +12 more
TL;DR: The results reported herein demonstrate the general possibility of amplifying minor localized electronic effects to achieve major changes in material's properties via involvement of strongly correlated electrons.

Powerful scriptable ray tracing package xrt
TL;DR: In this article, the authors present an open source ray tracing tool that offers several useful features in graphical presentation, material properties, advanced calculations of synchrotron sources, implementation of diffractive and refractive elements, complex (also closed) surfaces and multiprocessing.

“Chemical Metamagnetism”: From Antiferromagnetic PrCo2P2 to Ferromagnetic Pr0.8Eu0.2Co2P2 via Chemical Compression
Kirill Kovnir,William M. Reiff,Alexey P. Menushenkov,Alexander Yaroslavtsev,Roman Chernikov,Michael Shatruk +5 more
TL;DR: In this article, a strong chemical compression that "squeezes out" electrons from the localized Eu 4f levels into the delocalized Co 3d subband is described.
