In this work, Cu2O nanoparticles were successfully prepared onto the surface of two-dimensional graphitic carbon nitride (g-C3N4) by using a simple solution chemistry approach. An environment-friendly reducing agent, glucose, was used for synthesis NPs g-C3N4 without any surfactant or additives. The composition, crystalline structure, morphology, as well other properties have been investigated ...

Abstract CotA laccase was successfully expressed from Pichia pastoris . Magnetic reduced graphene oxide (MRGO) nanocomposite synthesized and functionalized with iminodiacetic acid (IDA-NH 2 ), then chelated Cu 2+ for effective immobilization His-tagged laccase. The -chelated MRGO (MRGO-IDA-Cu ) showed 175 mg/g-support adsorption capacity. of MRGO-IDA-Cu nano-hybrid composite confirmed by Raman ...

The toxicity of metal ions on ecosystems has led to increasing amounts research their removal from wastewater. This paper presents the efficient application a carbon magnetic nanocomposite as an adsorbent for elimination (copper, lead and zinc) aqueous solutions. A Box–Behnken factorial design combined with response surface methodology was conducted investigate effect interactions three variabl...

Heterogeneous photocatalysis has been considered one of the most effective and efficient techniques to remove organic contaminants from wastewater. The present work was designed examine photocatalytic performance metal (Cu Ni) doped ZnO nanocomposites in methyl orange (MO) dye degradation under UV light illumination. wurtzite hexagonal structure observed for both undoped/doped a crystalline siz...

BACKGROUND The aim of this study was to evaluate the interaction of bioactive and biodegradable poly (lactide-co-glycolide)/bioactive glass/hydroxyapatite (PBGHA) and poly (lactide-co-glycolide)/bioactive glass (PBG) nanocomposite coatings with bone. MATERIALS AND METHODS Sol-gel derived 58S bioactive glass nanoparticles, 50/50 wt% poly (lactic acid)/poly (glycolic acid) and hydroxyapatite na...

Chitosan–silver (CS–Ag) nanocomposite materials were synthesized by a simple chemical method. The synthesized CS–Ag nanocomposite contains 20 wt% silver. Silver nanoparticles were synthesized by chemical reduction method as well. The CS–Ag nanocomposite was characterized using Field emission scanning electronic microscope (FESEM), X-ray diffraction (XRD) and Fourier transform infrared spectrosc...
