The use of metal oxide nanomaterials as photocatalysts for wastewater treatment has received significant attention in recent years due to their unique physicochemical properties. In this study, we a polyol-mediated refluxing method synthesize silver-incorporated copper (Ag@CuO NMs). tetra butyl ammonium bromide (TBAB) capping agent and ethylene glycol reducing Ag+ Ag is elaborated upon. prepare...

Tert-butyl carbazate (1) reacted with ammonium thiocyanate and phenyl isothiocyanate to afford the corresponding 5-tert-butoxy-4H-1, 2, 4-triazole-3-thiol (3) 5-tert-butoxy-4-phenyl-2H1, 2, 4-triazole-3(4H)-thione 5 respectively. Compound (1) also reacted with carbon disulfide and potassium hydroxide to afford 5-tert-butoxy-1, 3, 4-oxadiazole-2(3H)-thione 6. Treatment of 6 with methyl iodide, 2...

The octa-hedral cluster core of the anion in the structure of the title compound, (C(16)H(36)N)(3)[Mo(6)(C(4)H(9)S)(6)(μ(3)-Cl)(7)(μ(3)-S)]·2H(2)O, has -3 site symmetry. Two μ(3)-Cl atoms fully occupy positions in the cluster core, while the remaining six positions are statistically occupied by Cl and S atoms in a 1:5 ratio. The fully occupied Cl-atom positions are located on sites with 3 symme...

The polarographic or voltammetric behaviour of a selected group of tetra-alkyl ammonium halides and related compounds in liquid sulphur dioxide was investigated, using a stationary disk platinum indicating micro-electrode and a silver/silver-bromide reference electrode withcompensation for the IR drop of the solution. The electrochemical oxidation-reduction patterns are characteristic of the na...

In view the of wide scope of structural information of biomolecules in biocompatible ionic liquids (ILs) in various applications including chemical and biochemical, it is essential to study the productive preferential interactions between biological macromolecules and biocompatible ILs. We have therefore explored the stability and activity of α-chymotrypsin (CT) in the presence of five ILs from...

In the title compound, (n-C(4)H(9))(4)N(+)·C(7)H(5)O(3) (-)·2H(2)O, the carboxyl-ate group is twisted slightly out of the plane of the attached benzene ring, the two C-C-C-O torsion angles being -8.9 (2) and -10.7 (2)°. The anion inter-acts with two water mol-ecules through several O-H⋯O hydrogen bonds, forming wide ribbons along the a axis constructed from two anion-water chains. These ribbons...

In the asymmetric unit of title coordination polymer, {(C(16)H(36)N)[Zn(3)(C(9)H(3)O(6))(2)(OH)]·0.25H(2)O}(n), there are three independent Zn(2+) cations, two benzene-1,3,5-tricarboxyl-ate ligands and a μ(3)-bridging hydroxide group, together with a tetra-n-butyl-ammonium counter-cation and a partially occupied water molecule of solvation (occupancy 0.25). Each Zn ion is coordinated by three c...

BACKGROUND Patients with acute renal colic usually require immediate diagnosis and treatment. In this clinical trial analgesic effect of hyoscine N-butyl bromide and desmopressin combination in comparison with hyoscine N-butyl bromide alone in patients with acute renal colic induced by urinary stones was assessed. METHODS The study included 114 patients randomly allocated in two groups (A and...
