Synthesis and characterization of paramagnetic isotropic glycine manganese chloride single crystal with various dopant concentrations

Results in Physics, 2019
Single crystals of α and γ glycine manganese chloride (GMC) were prepared using four dopant concentrations of MnCl2 in the molecular formula (C2H5NO2)1−x(MnCl2)x, where [x = 0.005, 0.02, 0.04, 0.05]. The crystals showed: nonlinear optical (NLO) activity,

Characterization of Shewanella oneidensis MtrC: a cell-surface decaheme cytochrome involved in respiratory electron transport to extracellular electron acceptors [PDF]

, 2007
MtrC is a decaheme c-type cytochrome associated with the outer cell membrane of Fe(III)-respiring species of the Shewanella genus. It is proposed to play a role in anaerobic respiration by mediating electron transfer to extracellular mineral oxides that ...

Electron paramagnetic resonance study of Eu2+ centers in melt-grown CsBr single crystals [PDF]

, 2012
The structure of Eu2+ monomer centers in CsBr single crystals is investigated using electron paramagnetic resonance (EPR) spectroscopy. These centers are produced by heating the melt-grown crystals above 600 K in vacuum followed by a rapid quench to room

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

Advanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
