A novel method developed by a Cornell-led research team offers a dual solution to two pressing environmental problems: ...

Gold nanoparticles (AuNPs) are nanoscale particles of gold ... It involves the reduction of chloroauric acid (HAuCl 4) with sodium citrate in an aqueous solution. The citrate ions act as both reducing ...

A research team from Cornell University has created a method to recover gold from e-waste and repurpose it as a catalyst for ...

He subsequently found that they comprised nanoparticles of gold supported on the oxide. This combination showed activity at temperatures as low as −76 °C — this is close to the coldest ...

“Gold nanoparticles can easily be measured using dark-field microscopy ... “Ultimately, we want to convert it into a mature industry solution.” Other RAPTOR team members include Alexandra Boltasseva, ...

but it also formed and accumulated gold nanoparticles. Remarkably, the gold had a tendency to deposit on existing gold grains rather than forming new ones.” The electric spark generated by the ...

Silver nanoparticles (AgNPs) are widely used in medicine for their antimicrobial and drug delivery properties, but their toxicity has raised concerns. In a recent research published in Nano ...

It involves the reduction of metal ions in solution using reducing agents such as sodium ... through biomolecules present in their cells or extracts. Metal nanoparticles, particularly gold and silver, ...

The supernatant solution luminesced when it was excited ... Carbon nanotubes, semiconducting nanocrystals and gold nanoparticles show signs of dose-dependent toxicity, which is highly dependent ...
