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 ...
Nov. 23, 2021 — Alkynes have many uses in industry. Until now, it was assumed that gold- or platinum-based catalysts were absolutely necessary for certain chemical reactions with alkynes. Chemists have now succeeded ...
Jan. 30, 2023 — The precious metals, such as platinum, palladium and rhodium, in catalytic converters make the vehicle devices attractive to thieves, but researchers are working to reduce the amount of precious ...
Feb. 10, 2021 — Scientists have uncovered dynamic, atomic-level details of how an important platinum-based catalyst works in the water gas shift reaction. The experiments provide definitive evidence that only ...
Jan. 22, 2021 — Catalysts are getting smaller - 'single-atom' catalysts are the logical end point of this downsizing. However, individual atoms can no longer be described using the rules developed from ...
June 14, 2022 — Engineers have developed a catalyst by adding a flat platinum interface to NiFe-layered double hydroxide (LDH). The new catalyst increases hydrogen production efficiency and displays 11.2 times ...
Apr. 24, 2023 — Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing ...
Jan. 13, 2021 — Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its ...
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. 26, 2022 — A new method to anchor single atoms of platinum-group metals on nanometer-sized islands allows for efficiently using these expensive metals as catalysts for a wide variety of applications. ...
