Dec. 9, 2022 Researchers have used gold extracted from electronic waste as catalysts for reactions that could be applied to making ...
Apr. 22, 2021 Chemists quantify the release mechanism of silver ions from gold-silver nanoparticle alloys. The nanoparticles are being studied for use as catalyst in hydrogen evolution and other ...
June 25, 2021 New research has found tiny amounts of gold can be trapped inside pyrite, commonly known as 'fool's gold,' which would make it much more valuable than its name ...
Mar. 22, 2022 A research team has reported an in-depth analysis of precious metal adsorption onto Galdieria sulphuraria algae. The combination of X-ray absorption fine structure spectroscopy and single-cell ...
Oct. 18, 2022 Researchers have created intermetallic alloy nanoparticles of palladium and zinc with an alternating arrangement of zinc and palladium atoms. The intermetallic alloy is more corrosion-resistant than ...
Apr. 11, 2023 Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light ...
Jan. 23, 2021 Researchers have shown a way to make bulk metals by smashing tiny metal nanoparticles together, which allows for customized grain structures and improved mechanical and other ...
Sep. 18, 2023 Researchers discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical ...
Mar. 21, 2022 Researchers have developed a bimetallic catalysis technique using gold and palladium nanoparticles on a conductive support that could lead to new design pathways for greener production of renewable ...
Sep. 21, 2022 Sparklers can be a lot of fun -- glimmering, fizzing and spitting out arcs of light from handheld sticks or tubes on the ground. But the metals that they're usually made with limit what the ...
