Synthesis of S- and N-functionalized dithiocarbamates from cyclic sulfates [PDF]

open access: yes, 2013
A novel methodology for the synthesis of S- and N-functionalized dithiocarbamates starting from cyclic sulfates, amines and carbon disulfide by using different protocols, including microwave assistance and a multicomponent variant, has been developed ...

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.

Morphological, Structural, and Spectral Characteristics of Amorphous Iron Sulfates [PDF]

open access: yes, 2015
Current or past brine hydrologic activity on Mars may provide suitable conditions for the formation of amorphous ferric sulfates. Once formed, these phases would likely be stable under current Martian conditions, particularly at low- to mid-latitudes ...

Sulfates in Martian Layered Terrains: The OMEGA/Mars Express View,

open access: yes, 2005
The OMEGA/Mars Express hyperspectral imager identified hydrated sulfates on light-toned layered terrains on Mars. Outcrops in Valles Marineris, Margaritifer Sinus, and Terra Meridiani show evidence for kieserite, gypsum, and polyhydrated sulfates.

Recombination Luminescence and Electron–Hole Trapping Centers in BaSO4-Bi Phosphor

open access: yesCrystals
This study of the BaSO4-Bi phosphor has revealed that the accumulated energy after external optical excitation exhibits specific characteristics. During irradiation with photon energy exceeding the bandgap, in addition to the intrinsic ultraviolet ...

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 ...

Sulfates hydrating bulk soil in the Martian low and middle latitudes [PDF]

open access: yes, 2014
© 2014. American Geophysical Union. All Rights Reserved. The evidence for sulfate-bearing strata, across Late-Noachian to Amazonian eons, suggests a central role for sulfates in acidity and salinity of Martian paleofluids and the planet\u27s habitability.
