Gold is generally associated with pyrite (iron disulfide, FeS 2), and pyrite-induced gold precipitation is critical to the formation of high-grade gold deposits. However, the role of pyrite in ...

Some key applications of gold nanoparticles include photonics, medicine and catalysis. 3 Gold nanoparticles have a high absorption cross-section in the visible and infrared regions, which can be tuned ...

Gold nanoparticles (AuNPs) are nanoscale particles of gold, typically ranging in size from 1 to 100 nanometers (nm). These nanoparticles exhibit unique physical, chemical, and optical properties that ...

OULU, Finland — A new study has uncovered a connection between bacteria living in Norway spruce needles and gold nanoparticles. This discovery, made by the research team at the University of Oulu and ...
