In the title hydrated double salt, 4,4'-(ethene-1,2-di-yl)dipyridin-1-ium hexa-aqua-iron(II) bis-(sulfate) monohydrate, (C12H12N2)[Fe(H2O)6](SO4)2·H2O, the Fe(II) cation is coordin-ated by six water mol-ecules in a slightly distorted octa-hedral geometry; the two pyridine rings of the 4,4'-(ethene-1,2-di-yl)dipyridin-1-ium cation are twisted to each other by a dihedral angle of 11.84 (10)°. In ...

zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...

Sulfate-bearing soils, which causes many engineering problems, e.g., cracking, collapse, and pavement layer settlement, are often encountered in the construction of pavements. Ground granulated blast furnace slag (GGBS)-magnesia (MgO) has been regarded as an effective curing agent treatment sulfate-bearing soil containing gypsum. However, field soils usually include other forms sulfates, such s...

a split plot experiment based on complete block design with three replications was carried out to evaluate the effect of irrigation and potassium fertilizer on yield and yield components of green beans, in 2011 at ahvaz. two levels of irrigation (normal irrigation and drought) and four levels of potassium sulfate fertilizer (0, 25, 50 and 100 kg ha-1) were evaluated in this study. the results o...

Although the sulfate/anion transporter (sat-1; SLC26A1) was isolated from a rat liver cDNA library by expression cloning, localization of sat-1 within the liver and its contribution to the transport of sulfate and organo sulfates have remained unresolved. In situ hybridization and immunohistochemical studies were undertaken to demonstrate the localization of sat-1 in liver tissue. RT-PCR studie...

The asymmetric unit of the title salt, 2C4H8N5 (+)·SO4 (2-)·5H2O, contains four 2,4,6-tri-amino-pyrimidinium (TAPH(+)) cations, two sulfate anions and ten lattice water mol-ecules. Each two of the four TAPH(+) cations form dimers via N-H⋯N hydrogen bonds between the amino groups and the unprotonated pyrimidine N atoms [graph-set motif R 2 (2)(8)]. The (TAPH(+))2 dimers, in turn, form slightly o...

The sulfate-reducing bacteria-mediated reduction process is considered to be an important mechanism affecting arsenic migration and transformation in anaerobic environments. To investigate the effect of bacteria a high-arsenic aquifer on transformation, typical Desulfovibrio vulgaris was selected for micro-cosmic experiments simulate groundwater environment with or without sulfate amendment. Fe...

introduction: migraine is a common cause of emergency department (ed) visits. to date, there is no recommended drug of choice for pain management of these patients. in the present study, we aimed to evaluate the effectiveness of ketorolac and magnesium sulfate in this regard. methods: this is a cross-sectional study performed on all 18 - 60 year-old patients, visiting two different eds with com...

In the crystal structure of the title salt hydrate, C9H8NO(+)·HSO4 (-)·H2O, the quinoline N-H atoms are hydrogen bonded to the bis-ulfate anions. The bis-ulfate anions and water mol-ecules are linked together by O-H⋯O hydrogen-bonding inter-actions. The cations and anions form separate layers alternating along the c axis, which are linked by N-H⋯O and O-H⋯O hydrogen bonds into a two-dimensional...

The title salt, C(10)H(7)N(2) (+)·HSO(4) (-), is formed by the transfer of a proton from H(2)SO(4) to the N atom of 2-cyano-quinoline during crystallization. The quinoline ring system is approximately planar with a maximum deviation of 0.013 (3) Å. In the crystal, the cations are linked to the anions via inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming a layered network.
