The cadmium sulfide nanoparticles were synthesized from the nickel-cadmium cake of a hydrometallurgical zinc producing plant and sodium sulfide as Cd2+ and S-2 sources, respectively. Also, the synthesis process was performed by using the secretions of Bacillus licheniformis as bio-surfactant. Initially, in order to obtain a cadmium rich solution, two following steps were carried out: 1) Alkalin...

In the present work, ZnO/Bi2O3, SnO2/Bi2O3/Bi2O4 mixed oxide, Bi2O3 rod-like and SnO2 nanoparticle have been synthesized. The obtained samples were characterized by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The optical properties of samples were evaluated by UV-Vis spectrophotometer. The photocatalytic activity of samples was evaluated by decolorization o...

In this research, acute toxicity (LC) of zinc oxide nanoparticle on Beluga (Huso huso) andcommon carp (Cyprinus carpio) was studied. The experiment was conducted using theOrganization for Economic Co-operation and Development (No. 202) method. For bothspecies, 96hLC10 was determined to be more than 200 mg/l. To assess the effects of zinc oxidenanoparticles on blood factors, leukocyte index coun...

Development of ternary metal oxide (TMO) based electron transporting layer (ETL) for perovskite solar cell open a new approaches toward efficient a unique strategy for solid state dye-sensitized solar cells (ssDSSCs). In the present investigation, highly porous zinc tin oxide (Zn2SnO4) scaffold nanofibers has been synthesized by electrospinning technique and successfully used for methyl ammoniu...
