The impact of phytopathogenic microorganisms in several crops causes significant losses agrifood industry, spoilage throughout food chain and storage. Nanoparticles plant extracts have been highlighted by their antimicrobial properties applied packaging, agriculture, drug delivery systems other medical approaches. Over the past few years, this group studied application ZnO nanoparticles agroind...

background: metal nanoparticles have been recently applied in dentistry because of their antibacterial properties. this study aimed to evaluate antibacterial effects of colloidal solutions containing zinc oxide (zno), copper oxide (cuo), titanium dioxide (tio2) and silver (ag) nanoparticles on streptococcus mutans and streptococcus sangius and compare the results with those of chlorhexidine and...

Abstract:Electroless Nickel-phosphorus (EN) coatings provide high performance in various industrial fields due to their unique properties such as excellent corrosion and wear resistance. This paper aims to study the effect of ZnO nano-particles addition on corrosion behavior of EN coatings. Various amounts of ZnO nano-particles with average diameter of 50 nm were added to hypophosphite reduced ...

Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...
