Cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants of cadmium acetate and sodium sulfide in the presence of thioglycerol (TG) as capping agent in ethanol solvent. Different nanoparticle sizes and size distribution were obtained through varying the molarities of thioglycerol. At higher TG concentration, synthesis provides a nearly monodisperse nanopart...

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...

CdSe nanostructures were synthesized by using green chemical route as starch was used as capping agent. XRD, HR-TEM, SEAD, UV and PL studies were made for structural and optical properties of the prepared sample. Film morphology and the thickness measurement of n-CdSe were carried out with AFM analysis. I-V characteristics curve of this junction confirmed the formation of Schottky contact betwe...

Core promoter controls the initiation of transcription. Core promoter sequence change can disrupt transcriptional regulation, lead to impairment of gene expression and ultimately diseases. Therefore, comprehensive characterization of core promoters is essential to understand normal and abnormal gene expression in biomedical studies. Here we report the development of EVDC (Exome-based Variant De...

Green chemistry is an alternative route of which has overcome the limitations of other chemical methods. Nanocrystalline zinc oxide (NC-ZnO) with different structures have been grown on quartz plates by spin coating method by the use of plant extracts of Citrus aurantifolia which can be a cost effective and eco-friendly approach.. The present exploration describes the synthesis and characteriza...

We report the growth and characterization of Cu nanoparticles thin film of on glass substrate by pulse laser deposition method. The Cu thin film prepared with different energy 50, 60, 70, and 80 mJ. The energy effect on the morphological, structural and optical properties were studied by AFM, XRD and UV-Visible spectrophotometer. Surface topography studied by atomic force microscopy revealed na...

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for pr...
