In the present paper, we report crystal structures of four types ([A(1)H][A(2)H]Y, [A(1)H]3[A(2)H]Y2, A(1)H[A(2)H···A(2)]Y, and A(1)H[A(1)H···A(2)]Y) mixed salts containing sulfate anion (Y = SO42−) amino acids A, i.e., sarcosine (Sar), dimethylglycine (DMG), betaine (Bet), β-alanine (β-Ala), l-proline (l-Pro): (β-AlaH)(DMGH)SO4·2H2O (I), (β-AlaH)(BetH)SO4 (II), (β-AlaH)(l-ProH)SO4 (III), (BetH...

The utilization of pig manure as a source of nutrients for the dissimilatory reduction of sulfates present in phosphogypsum was investigated. In both types of media used (synthetic medium and raw pig manure) increased utilization of sulfates with growing COD/SO4(2-)ratio in the medium was observed. The percent of sulfate reduction obtained in synthetic medium was from 18 to 99%, whereas the val...

[NC4H12][(UO2)6(H2O)2(SO4)7] is the first organically templated actinide sulfate with a three-dimensional framework structure; it has channels of dimensions 8.5 A x 8.5 A, running along the [001] direction, containing tetramethylammonium cations.

The ability of sulfate aerosols to reflect solar radiation and simultaneously act as cloud condensation nuclei renders them central players in the global climate system. The oxidation of S(IV) compounds and their transport as stable S(VI) in the Earth's system are intricately linked to planetary scale processes, and precise characterization of the overall process requires a detailed understandi...

The crystal structure of tamarugite [sodium aluminium bis-(sulfate) hexa-hydrate] was redetermined from a single crystal from Mina Alcaparossa, near Cerritos Bayos, southwest of Calama, Chile. In contrast to the previous work [Robinson & Fang (1969 ▶). Am. Mineral. 54, 19-30], all non-H atoms were refined with anisotropic displacement parameters and H-atoms were located by difference Fourier me...

Franzinite, ideally [(Na,K)30Ca10][Si30Al30O120](SO4)10•2H2O, a feldspathoid belonging to the cancrinite group, has a tenlayer stacking sequence. Its structure was solved in the space group P321 to an R value of 5.96%. Cell parameters are a 12.916(1), c 26.543(3) Å. The framework, characterized by the stacking sequence ABCABACABC, contains regular alternations of two “cancrinite” and two “sodal...

In our previous work fused pyrimidine and thiopyrimidine nucleoside analogs (2, 3b, 3c, 4a and 4c) as well as sulfated oligosaccharides (Maltose SO4, Raffinose SO4, Stachyose SO4, Chondroitin-6-sulfate, Maltohexaose SO4) were prepared. The objective of this study was to elucidate the antitumor activity of prepared compounds against Erlich ascites carcinoma cells (EAC) bearing mice through monit...

In the present work, polyvinylidene fluoride's (PVDF) electrical and optical properties have been studied as a function of cerium sulfate tetrahydrate called Ce(SO4)2. Experimental result shows that relative percentage β phase (Fβ%) increases by almost 55 % with Ce(SO4)2 addition in polymeric matrix. The dielectric permittivity measurements presented an increase, at 1 KHz, 62% up to 0.8% conten...

Sulfate-reducing bacteria (SRB) are a group of microbes that use sulfate (SO4 ) as a final electron acceptor instead of oxygen for respiration (Al-Zuhair, El-Naas et al. 2008). SRB are able to use a very wide spectrum of different low molecular organic compounds (e.g. lactate, acetate, proprionate, succinate, pyruvate, ethanol, sugars, etc.) for growth, with SO4 being reduced to hydrogen sulfid...

In the title salt, (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O, the Ni(II) cation is located on a centre of inversion and exhibits a slightly distorted octa-hedral arrangement of water mol-ecules. The Ni-O bond lengths in the complex [Ni(H2O)6](2+) cation show a distribution as in the related Tutton salt (NH4)2[Ni(H2O)6](SO4)2, but are longer in average [2.056 (13) versus 2.037 (12) Å]. The noncoordinating ...
