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") ...

Encyclopedia of Solid-Liquid Interfaces, Edited by Wandelt and Bussetti 2023, DOI (current, online): https://doi.org/10.1016/B978-0-323-85669-0.00082-9 The oxygen ...

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 ...

Traditional oxygen-ion–conducting cells require high operating temperatures, creating cost, durability, and material compatibility challenges. Protonic ceramic cells (PCCs) offer an alternative, ...

See Blog at Nature Catalysis: Behind the Paper. While catalytic mechanisms on electrode surfaces have been proposed for decades, the pathways by which the product’s chemical bonds evolve from the ...

Many different mechanisms have been suggested for the oxidative lipid fragmentations that produce biologically active aldehydes such as 4-hydroxynon-2-enal (HNE), oxononanoyl phosphatidylcholine ...

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 ...
