A series of CuO-Cu2O/TiO2 nanocomposite samples were prepared by the sol-gel method. Before applying the sol-gel method, the Cu(OH)2 nanostructure on Cu powders were formed by in-situ solution treatment. The samples were characterized through some techniques and the photocatalytic performance of CuO-Cu2O/TiO2 nanocomposites for gas-phase 2-propanol photo-oxidation under UV and sunlight type ill...

A series of copper-based systems containing two different nanocomposites (Cu2O/CuO and Cu2O/Cu) was synthesized by the egg white assisted auto-combustion route. This method distinguished simplicity its steps, low cost, one-pot synthesis process at temperature and, short time. The characterization as prepared carried out using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning ...

Through the microwave assisted fast synthesis method, Zinc Magnesium Oxide nanocomposite was prepared. Zinc Magnesium Oxide nanocomposite heated at 500oC was used for further structural, optical and antibacterial studies. The Debye Scherrer equation was used to calculate the average particle size of the nanocomposite. The optical characterization of the oxide nanocomposite was carried out by UV...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) has been responsible for serious hospital infections worldwide. Nanomaterials are an alternative to conventional antibiotic compounds, because bacteria are unlikely to develop microbial resistance against nanomaterials. In the past decade, graphene oxide (GO) has emerged as a material that is often used to support and stabilize silve...

BACKGROUND The increasing use of nanoparticles and nanocomposite in pharmaceutical and processed food industry have increased the demand for nontoxic and inert metallic nanostructures. Chemical and physical method of synthesis of nanostructures is most popular in industrial production, despite the fact that these methods are labor intensive and/or generate toxic effluents. There has been an inc...

bismuth sulfide nano-rods and nano-flowers were synthesized via a hydrothermal reaction at a relatively low temperature. thioglycolic acid is used as sulfur source and capping agent simultaneously. bi2s3 nanostructures were then added to acrylonitrile-butadiene-styrene (abs) copolymer. the thermal stability behavior of abs filled with bismuth sulfide nano-rods were investigated by thermogravime...

In biomedical applications, polyethylene glycol (PEG) functionalization has been a major approach to modify nanocarriers such as nano-graphene oxide for particular biological requirements. However, incorporation of a PEG shell poses a significant diffusion barrier that adversely affects the release of the loaded drugs. This study addresses this critical issue by employing a redox-responsive PEG...

PURPOSE With the wide recognition of oncostatic effect of melatonin, the current study proposes a potential breast cancer target multimodality treatment based on melatonin-loaded magnetic nanocomposite particles (Melatonin-MNPs). METHODS Melatonin-MNPs were fabricated by the single emulsion solvent extraction/evaporation method. RESULTS Based on the facilitated transport of melatonin by the...

The simple design of CuOmicro-/nanostructures has recently attracted tremendous interest particularly for the enzyme-less sensing of biological molecules due to their intrinsic electronic and catalytic properties. Consequently attention has been directed to the development of new CuO nanomaterials that have multi-interdisciplinary applications. Herein, we report for the first time the fabricati...
