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

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 ...

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

It involves the reduction of metal ions in solution using reducing agents such as sodium borohydride ... stabilize the resulting nanoparticles through biomolecules present in their cells or extracts.

SPR occurs when light interacts with metal nanoparticles ... The printed OFPs were immersed in a boiling solution of gold(III) chloride hydrate, which acted as the precursor for AuNPs.

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 ...
