In this research, the nanosized Fe2V4O13 complex oxide material was synthesized by hydrothermal method. Its structure, morphology characterization, and other properties were determined using X-ray, SEM, EDX, DTA-TG methods. The catalytic activity of evaluated in terms decolorization degradation Indigo carmine dye. optimal condition for reusability catalyst determined. results showed that hetero...

A factorial combination of pretreatments, fixatives, and stains was examined to identify the best available method for staining the chromosomes of strawberry (Fragaria × ananassa Duch. ‘Chandler’) root-tip cells. Three pretreatments ( a -bromonaphthalene, p -dichlorobenzene, and 8-hydroxyquinoline), three fixatives (Farmer’s fluid, Carnoy’s fluid, and Newcomer’s fluid), and five stains (acetoca...

Three new methods are described for the assay of lamivudine in bulk drug and in tablet dosage forms using chloramine-T and two dyes, methyl orange and indigo carmine, as reagents. In titrimetry, aqueous solution of lamivudine is treated with a measured excess of chloramine-T in sulphuric acid medium and after the oxidation of lamivudine is judged to be complete, the unreacted oxidant is determi...
