Feb. 22, 2024 Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less ...
Oct. 3, 2022 Transition metals have many applications in engineering, electrochemistry and catalysis. To understand their properties, the interplay between atomic localization and delocalization of the outer ...
Apr. 8, 2021 Researchers have developed a single-crystal cobalt phosphide nanorod catalyst for the reductive amination of carbonyl compounds to primary amines. The nanorod catalyst performed better than ...
Apr. 29, 2021 Researchers have now discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which ...
July 12, 2022 A thermoelectric metal oxide film with a thermoelectric figure of merit of ~0.55 at 600°C has been discovered, opening new avenues towards the widespread use of thermoelectric ...
Jan. 30, 2024 Nanoclusters (NCs) of transition metals like cobalt or nickel have widespread applications in drug delivery and water purification, with smaller NCs exhibiting improved functionalities. Downsizing ...
Jan. 18, 2024 In the switch to 'greener' energy sources, the demand for rechargeable lithium-ion batteries is surging. However, their cathodes typically contain cobalt -- a metal whose extraction has ...
July 6, 2021 Chemical engineers have developed a machine-learning model that can predict a compound's oxidation state, a property that is so essential that many chemists argue it must be included in the ...
Aug. 9, 2021 As a rule, most catalyst materials deteriorate during repeated catalytic cycles – they age. But there are also compounds that increase their performance over the course of catalysis. One example is ...
June 23, 2021 Scientists have made significant progress in developing battery cathodes using a new class of materials that provide batteries with the same if not higher energy density than conventional lithium-ion ...
