Catalytic fast pyrolysis is a promising way to convert lignin into fine chemicals and fuels, but current approaches lack selectivity and yield unsatisfactory conversion. Understanding the pyrolysis ...
For the first time, researchers have imaged and identified the bond configuration of the intermediates in a complex sequence of chemical transformations of enediyne molecules on a silver surface and ...
Criegee intermediates (CIs)—highly reactive species formed when ozone reacts with alkenes in the atmosphere—play a crucial role in generating hydroxyl radicals (the atmosphere's "cleansing agents") ...
Researchers have now been able to study the surface of iron and ruthenium catalysts when ammonia is formed from nitrogen and hydrogen. A better knowledge of the catalytic process and the possibility ...
For organic chemists, the free-radical hydrostannylation of alkynes to produce vinylstannanes is a key step in important cross-coupling and other reactions. Every published mechanism has hinged solely ...
The molecular structure of a catalytically active key intermediate is determined in solution by employing 2D IR spectroscopy measuring vibrational cross-angles. The formate intermediate (2) in the ...
Chemical reactions rarely go from start to finish in a single step, as intermediates form during the transition between starting materials and final products. For example, when our bodies synthesize ...
Traditional oxygen-ion–conducting cells require high operating temperatures, creating cost, durability, and material compatibility challenges. Protonic ceramic cells (PCCs) offer an alternative, ...
One of the long-standing goals being pursued by chemists has been to succeed in following and directly visualising how the structures of molecules change when they undergo complex chemical ...
