Effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with Borax. Nanosilver and Borax were applied in pressure vessel using Rueping method. The size range of silver nanoparticles was 20-80 nm. Specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

Objective(s): Nanosilver is one of the most widely used nanomaterials due to its strong antimicrobial activity. Thus, because of increasing potential for exposure of human to nanosilver, there is an increasing concern about possible side effects of these nanoparticles. In this study, we tested the potential dermal toxicity of nanosilver bandage on serum chemical biomarkers in mice.  Materials a...

 Nanotechnology presents countless opportunities to develop new and improved consumer products for the benefit of the society . A most prominent nanoproduct is nanosilver. Nanosilver particles are generally smaller than 100 nm and contain 20–15,000 silver atoms. Despite the wide application of nanomaterials, there is a serious lack of information concerning their impact on human health. In the ...

In this study, PPy@Ag/rGO nanocomposites were successfully synthesized via the one-pot hydrothermal method using graphene oxide, pyrrole monomer and silver nitrate. The structures morphologies of as-obtained ternary systematically investigated by scanning electron microscopy (SEM) transmission microscope (TEM). It was found that PPy@Ag NPs well distributed on reduction oxide nanoflakes. minimum...

This study investigated the concentration/time dependent effects of nanosilver colloid on the motionparameters of the ejaculated ram spermatozoa in vitro. After incubation of sperm samples for 30, 60, 120 and 180 min in the presence of nanosilver colloid (0, 0.001, 0.01, 0.1, 1 and 10 ppm), the motion parameters were evaluated by computer assisted sperm analysis. There was a significant (P

Nanotechnology has been advanced since the last decades. Among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. Its release into natural water bodies is inevitable due to its broad applications. Nanosilver (nAg) was prepared via Tollens method using. The morphology, size distribution and average size of the obtained nAg was characterized using Tr...

background: bovine mastitis is the most costly disease in dairy cows and causes significant decrease in milk production. this disease is one of the main reasons of antibiotic therapy in dairy cows. objectives: staphylococcus aureus is counted as a major pathogen associated with the outbreaks of mastitis in dairy herds. therefore, the purpose of the present study is to examine the antibacterial ...
