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 ...
Jan. 25, 2022 —Lanthanum trihydride, a compound of lanthanum and hydrogen, when lightly doped with oxygen shows potential as an efficient hydrogen carrier, according to a new study. Hydride ion (H--) conductors are ...
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 ...
Nov. 1, 2022 —To reduce the energy requirements of the Haber-Bosch process, which converts nitrogen and hydrogen to ammonia, researchers have developed a metal nitride catalyst containing an active metal (Ni) on a ...
Feb. 16, 2021 —Researchers used a particle accelerator and co-precipitation to study the chemical reactivity of single rutherfordium atoms. Such experiments will continue the advancement of relativistic chemistry ...
Feb. 15, 2022 —Scientists have managed to successfully make a transuranium complex where the central metal, here neptunium, forms a multiple bond to just one other element. Enabling study of such a bonding ...
Dec. 23, 2020 —Scientists report that the metal ruthenium, supported with lanthanide oxyhydrides, can efficiently catalyze the synthesis of ammonia at a much lower temperature than the traditional approach. In ...
Feb. 6, 2021 —Since element 99 -- einsteinium -- was discovered in 1952 from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is ...
Mar. 22, 2023 —An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare ...
Jan. 11, 2021 —When an LNO catalyst with a nickel-rich surface carries out a water-splitting reaction, its surface atoms rearrange from a cubic to a hexagonal pattern and its efficiency doubles. Deliberately ...
