The thermal decomposition of potassium and sodium-pyrosulfate [PDF]

open access: yes, 1969
Proceeding from KHSO4, K2S2O8, NaHSO4 and Na2S2O8, potassium- and sodium-pyrosulfates were prepared and their thermal decomposition was investigated by a T.G.A. method. This was done in order to clarify contradictory values found in the literature.

Combinatorial Roles of Heparan Sulfate Proteoglycans and Heparan Sulfates in Caenorhabditis elegans Neural Development [PDF]

open access: yes, 2014
Heparan sulfate proteoglycans (HSPGs) play critical roles in the development and adult physiology of all metazoan organisms. Most of the known molecular interactions of HSPGs are attributed to the structurally highly complex heparan sulfate (HS) glycans.

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 ...

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),
