چکیده
ABSTRACT. Curcumin nanoparticles (CurNP’s) were successfully synthesized, characterized, and used as a cross-linking dopant of polyvinyl alcohol/ sodium carboxymethyl cellulose (PVA/CMC) semi-natural polymer blend. Synthesized nanocomposite films (PVA/CMC/CurNP’s) characterized using Fourier transforms infrared FTIR spectroscopy tested for their resistance different bacterial grams. Obtained data shows that studied PVA polymerized cross-linked with CMC result hydrogen bonding between the carboxylic groups non-substituted hydroxyl molecule. The optical energy gap was found to be sensitive CurNP’s doping level, indirect transition dominant in samples. addition appears increase activity index all samples against both gram-negative positive bacteria, increases increasing level until specific optimal concentration.

Synthesis and investigation of structural, optical, and photocatalytic properties of BiFeO3/reduced graphene oxide nanocomposites
This study have been developed BiFeO3/reduced graphene oxide (BFO/RGO) nanocomposites by introduction of RGO in the structure of BFO nanoparticles in a short term ultrasonic treatment. The X-ray diffraction pattern and Fourier-transform infrared spectroscopy analysis reveal that the BFO/RGO composites were successfully synthesized. UV-visible absorption show that the introduction of RGO can eff...
