Significantly raising tetracyanoquinodimethane electrode performance in zinc‐ion battery at low temperatures by eliminating impurities

open access: yesBattery Energy, 2023
Applications of organic compounds‐based electrodes in aqueous zinc‐ion batteries (AZIBs) at low temperatures are severely restricted by the freezing of aqueous electrolytes and the inferior dynamic behavior of organic electrodes below zero.

Understanding electron-positron momentum densities in solids: effect of the positron distribution

open access: yesNukleonika, 2015
The influence of the positron distribution on the electron-positron (e-p) momentum densities (MDs) is studied in terms of the l (l = s, p, d, f) character of the initial electronic state.

Magnetic properties of HoFe6Al6H hydride: A single-crystal study

open access: yesJournal of Science: Advanced Materials and Devices, 2016
Crystal structure and magnetic properties were studied on a single crystal of HoFe6Al6H and compared with those of the parent HoFe6Al6 compound with a tetragonal crystal structure of the ThMn12 type. Hydrogenation leads to a 1% volume expansion. HoFe6Al6

TAPSO at Low Temperature

open access: yesActa Crystallographica Section C Crystal Structure Communications, 1996
The crystal structure of TAPSO, 2-hydroxy-3-[tris-(hydroxymethyl)methylamino]propane-1-sulfonic acid, C7H17NO7S, was determined at 153 K. This widely used buffer crystallizes as a zwitterion, 2-hydroxy-3-[tris(hydroxymethyl)methylammonio]propane-l-sulfonate, and crystal cohesion is provided by a dense network of hydrogen bonds.
