The butane-1,4-diammonium cation of the title compound, C(4)H(14)N(2) (2+)·2ClO(4) (-), lies on a special position of site symmetry 2/m, whereas the perchlorate anion is located on a crystallographic mirror plane. An intricate three-dimensional hydrogen-bonding network exists in the crystal structure with each H atom of the ammonium group exhibiting bifurcated inter-actions to the perchlorate a...

The title compound, (C(3)H(12)N(2))[Cr(2)O(7)], consists of a discrete dichromate anion with an eclipsed conformation and a propane-1,3-diammonium cation. Both kinds of ions have a mirror plane passing through the bridging O atom and the central methyl-ene C atom of the Cr(2)O(7) (2-) and C(3)H(12)N(2) (2+) moieties, respectively. Anions and cations are alternately stacked to form columns paral...

Many studies describe the positive effect of mycorrhiza, but few report on negative effects. Furthermore, there is a research gap mechanisms under which conditions symbiotic mycorrhizal plant interaction or parasitic one predominates. The study was conducted as field experiment over three years to investigate mycorrhiza (Rhizoglomus intraradices) and soil bacteria applications fertile soil. A s...

Continuous application of phosphate (P) mineral to soil renders apatite addition during each crop growing season which is great concern from a sustainable agriculture viewpoint. Use efficient solubilizing microbes (PSB) one the most effective ways solubilize this in soil. The current study targeted hydroxyapatite mines explore, isolate and characterize P solubilizers Efficiency isolated rock (h...

5,5'-Bis-(trinitromethyl)-3,3'-bi-(1,2,4-oxadiazole) is a new ternary CNO-compound. It has been synthesized by nitration of diammonium 5,5'-bis-(dinitromethanide)-3,3'-bi-(1,2,4-oxadiazole) with nitronium tetrafluoroborate. Single crystal X-ray diffraction studies show a remarkable high density. Thermal stability and sensitivities of the new compound were determined by differential scanning cal...

Filter cake is one of the main waste products of zinc processing industries and it contains a high amount of toxic heavy metals. In this research in order to reduce heavy metals leachability in filter cake, Portland cement, natural pozzolan, diammonium phosphate (DAP), triple superphosphate (TSP), lime, zinc oxide and ground granulated blast furnace slag (GGBFS) have been used. This research’s ...

To assess the clinical efficacy of diammonium glycyrrhizinate on drug induced liver injury and its effect related inflammatory factors in real world. A total 234 inpatients diagnosed with our hospital were continuously enrolled this retrospective world study, whom 110 treated divided into three groups according to combination. Treatment group (n=34) received injection+reduced glutathione inject...

Binding of cucurbit[6]uril (CB[6]) with the hexamethylene diammonium cation (HD(2+)) in the presence of sodium ions is elucidated at the atomic level. The most probable complex of CB[6] in saline solution is found to be CB[6]:Na(+). A two-stage binding process of CB[6]:Na(+) with HD(2+) is proposed.

The production of D-lactic acid by Lactobacillus lactis RM2-24 was investigated using modified media to increase the efficiency of the fermentation process. The results indicated that the addition of 5 g/l peptone and 1 g/l (NH4)2HPO4 enhanced D-lactic acid production by 32%, as compared to that obtained from non supplemented media, with a productivity of 3.0 g/l/h. Lactate dehydrogenase (LDH) ...
