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...

An eco-friendly approach is described for the green synthesis of gold nanoparticles using catechin as a reducing and capping agent. The reaction occurred at room temperature within 1 h without the use of any external energy and an excellent yield (99%) was obtained, as determined by inductively coupled plasma mass spectrometry. Various shapes of gold nanoparticles with an estimated diameter of ...

Silver nanoparticles were obtained via totally green synthesis from silver nitrate using glucose as reducing agent and sucralose as capping agent. Physico-chemical characterization of AgNPs was performed by UV-Visible absorption and transmission electron microscopy (TEM) in order to correlate biological/toxicological responses with AgNPs features. A detailed study of silver nanoparticles (AgNPs...

Assimilating green chemistry principles in nanotechnology is a developing area of nanoscience research nowadays. Thus, there is a growing demand to develop environmentally friendly and sustainable methods for the synthesis of nanoparticles that utilize nontoxic chemicals, environmentally benign solvents, and renewable materials to avoid their adverse effects. A simple, economic, and environment...

In this study, copper manganese oxide (CuMn2O4) nanoparticles were successfully synthesized by a simple sol-gel technique in the presence of lactose as the green capping agent. The lactose concentration effect on the crystalline size and magnetic properties of final products were systematically investigated. The structural, morphological, magnetic, and optical properties o...
