Oxidation of the facial-type trichloridoruthenium(III) complex bearing ethylbis(2-pyridyl-methyl)amine (ebpma), fac-[Ru(III)Cl3(ebpma)], with an equimolecular amount of (NH4)2[Ce(IV)(NO3)6] in acetonitrile afforded a ligand-based oxidation product of an acetonitriledichloridoruthenium(III) complex having bis(2-pyridylcarbonyl)aminato (bpca), [Ru(III)Cl2(NCCH3)(bpca)]. The complex changed into a trichloridoruthenium(III) complex by...

ISRN Pharmacol. 2012;2012:928901. doi: 10.5402/2012/928901. Epub 2012 Aug 13.

A series of eighteen 1,3,4-oxadiazole derivatives have been synthesized by treating aromatic acid hydrazides with carbon disulfide in ethanolic potassium hydroxide yielding potassium salts of 1,3,4-oxadiazoles. Upon neutralization with 1 N hydrochloric acid yielded crude crystals of 1,3,4-oxadiazoles, which...

A minimally invasive technique for the management of severely fluorosed teeth: A two-year follow-up.

European journal of dentistry

Chem Asian J. 2016 Mar 04;11(5):705-12. doi: 10.1002/asia.201500970. Epub 2016 Jan 28.

Nanoporous (NP) PtRu alloys with three different bimetallic components were straightforwardly fabricated by dealloying PtRuAl ternary alloys in hydrochloric acid. Selective etching of aluminum from source alloys generates bicontinuous network nanostructures with uniform size and structure. The as-made NP-PtRu...

Extraction of Gold(III) from Hydrochloric Acid Solutions with a PVC-based Polymer Inclusion Membrane (PIM) Containing Cyphos(®) IL 104.
