Mechanisms for the creation of intrinsic electron-hole trapping centers in a CaSO4 crystall

open access: yesEurasian Journal of Physics and Functional Materials, 2021
The mechanism of creation of electron-hole trapping centers in CaSO4 at 15-300 K was investigated by the methods of vacuum-ultraviolet and thermoactivation spectroscopy. It is shown that electron-hole trapping centers are formed upon trap of electrons in

Probing the catalytic activity of sulfate-derived Pristine and post-treated porous TiO2(101) anatase mesocrystals by the oxidative desulfurization of dibenzothiophenes [PDF]

open access: yes, 2017
Mesocrystals (basically nanostructures showing alignment of nanocrystals well beyond crystal size) are attracting considerable attention for modeling and optimization of functionalities. However, for surface-driven applications (heterogeneous catalysis),

Ageing affects chondroitin sulfates and their synthetic enzymes in the intervertebral disc

open access: yesSignal Transduction and Targeted Therapy, 2017
The depletion of chondroitin sulfates (CSs) within the intervertebral disc (IVD) during degenerative disc disease (DDD) results in a decrease in tissue hydration, a loss of fluid movement, cell apoptosis, a loss of nerve growth inhibition and ultimately,

Growth of various strains of sulfate-reducing bacteria of human large intestine

open access: yesБіологічні студії, 2012
New strains of sulfate-reducing bacteria from human intestine are obtained. These bacteria are vibrio-like (strains SRB Vib-1, SRB Vib-2, SRB Vib-3) and short rod-like (strains SRB Rod-4 and SRB Rod-5) forms.

Inorganic Amino-Nitro-Guanidinium Derivatives

open access: yesCrystals, 2012
1-Amino-3-nitroguanidine (ANQ, 1) was synthesized by hydrazinolysis of nitroguanidine (NQ) with hydrazine hydrate. Four different amino-nitroguanidinium salts (chloride (2), bromide (3), iodide (4) and sulfate (5)) were synthesized and structurally ...
