Electrochemical Detection of H₂O₂ Using Copper Oxide-Reduced Graphene Oxide Heterostructure.

Three dimensional heterostructure of CuO nanoparticle decorated reduced graphene oxide (rGO) was prepared by a facile and cost-effective technique. The structure and electrochemical properties of the CuO-rGO heterostructure composites were evaluated by various techniques. Transmission electron microscopy image analysis confirmed the presence of CuO nanoparticles onto the surface of the rGO sheets.

An approach towards optimization of the extraction of polyphenolic antioxidants from ginger (Zingiber officinale).

The present study aims to maximize the extraction of polyphenols from ginger (Zingiber officinale) through the statistical optimization of three influential process parameters ethanol (EtOH) proportion (%), temperature (°C) and extraction time (min). Response Surface Methodology (RSM) was employed to design experiments and study the interaction effects of these parameters on the extraction process. Analysis of Variance (ANOVA) was used for the analysis of regression coefficient, prediction of equation and case statistics.
