Two novel trinuclear europium complexes based on trisphen(1,3,5-tris{4-((1,10-phenanthroline-[5,6-d]imidazol-2yl)phenoxy)methyl}-2,4,6-trimethyl-benzene) as a second ligand were designed, synthesized, and characterized by FT-IR, (1)H NMR, UV-visible, photoluminescence (PL) spectroscopy, elemental analysis (EA) and ESI-MS. The geometries of these two trinuclear europium complexes were predicted ...

Skinnerite Cu3SbS3, which consists of non-toxic and low-cost elements, is a potential thermoelectric material, however, studies on its properties are limited. In this study, the optimal conditions mechanical alloying (MA) hot pressing (HP) for synthesis Cu3SbS3 phase were investigated, evaluated. The MA powder had theoretically predicted cubic skinnerite phase, remained even after HP. Thermal a...

Solvothermal reactions of CuCN with a set of flexible bipyrazolyl-based ligands with different spacer lengths [(dmpz)(CH(2))(n)(dmpz)] (dmpz = 3,5-dimethyl-pyrazolyl; n = 1-6) gave rise to six [CuCN](n)-based coordination polymers [(CuCN)(3)L](n) (1: L = dmpzm; 2: L = dmpze), [(CuCN)(2)L](n) (3: L = dmpzpr; 4: L = dmpzb; 5: L = dmpzp; 6: L = dmpzh). Compounds 1-6were characterized by elemental ...

in this work, all-solid-state potentiometric pvc membrane sensor was introduced for fast andsimple monitoring of mercury ions in waste water samples. the all solid sate electrode is made based on aconductive composite of graphite, reduced graphene oxide, epoxy resin on a copper wire. a thin layer pvcmembrane is then coated on the surface of the new conducting transducer. pvc membrane is compose...

a solid state fermentation method was developed for the production of citric acid from date pulp (obtained of date syrup production from the process) by aspergillus niger ptcc 5010. poor yield was obtained when potassium ferrocyanide treated date pulp were used as substrate, but methanol at a 3-4% concentration markedly increased the forma-tion of citric acid from the waste. the optimum range o...
