Effects of alfalfa-intercropping and nanosilver-impregnation were studied here on the specific gas permeability of 10-year old Populus nigra var. betulifolia. Specimens were impregnated with a 200 ppm aqueous dispersion of silver nanoparticles under 250 kPa pressure; the results were then compared with the un-impregnated specimens. The size range of silver nanoparticles was 10 to 80 nm. After t...

A novel nanosilver-deposited silica-coated Fe3O4 magnetic particle (Fe3O4@SiO2@Ag) with uniform size, good SERS activity and magnetic responsiveness was synthesized using amination polymer. The Fe3O4@SiO2@Ag magnetic particles have been successfully applied for ultrasensitive SERS detection of malachite green (MG) in water samples. The mechanism is that MG can be adsorbed on the silver surface ...

This study analyzed the growth and biochemical responses of six bacterial colonies isolated from the mucus of the estuarine polychaeta Laeonereis acuta (Nereididae) after exposure to a water suspension of fullerene (nC60) and nanosilver (nAg) separately (0.01; 0.10; and 1.00 mg/L) and together (0.01; 0.10; and 1.00 mg/L of nanosilver and 1.00 mg/L of fullerene added to each nAg concentration). ...

In the present study, fabrication and characterization of compound composite nanofibers of Polyvinyl Alcohol (PVA) with nano silver and Polyamide 6 (PA6) are demonstrated. Compound composite fibers with core-shell structure were made using co-axial electrospinning method. The shell was made up of nano silver (Ag) impregnated PVA while PA6 was the core material. These compound composite nanofibe...

Silver nanoparticles are added to a variety of textiles and home goods as an antimicrobial. Although silver has been used safely for centuries, some question whether the rapid expansion of new exposure sources to nanosilver could have adverse consequences.

Sintering of nanosilver paste has been extensively studied as a lead-free die-attach solution for bonding semiconductor power chips, such as the power insulated gated bipolar transistor (IGBT). However, for the traditional method of bonding IGBT chips, an external pressure of a few MPa is reported necessary for the sintering time of ~1 h. In order to shorten the processing duration time, we dev...

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...

COVID-19 virus has spread almost all over the world, including Indonesia until now. in people with diabetes mellitus have a risk of exacerbating symptoms. Diabetes is disease caused by high blood sugar levels. Nanogold very strong anti-oxidant capability, while nanosilver anti-bacterial properties. In this research, nanogold-nanosilver was presented form health drinking water packaged 1 L bottl...

This article presents a proposed insight into the anti-viral potential of silver nanoparticles against novel coronavirus disease (COVID-19). Possible mechanisms influence on are considered. Models nanosilver complexes with spike protein amino acids were constructed using computer quantum-chemical modeling. The values electron density distribution, highest occupied molecular orbital, lowest unoc...
