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 ...

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 ...

Researchers from Tokyo Metropolitan University have successfully traced the mechanism behind how an industrially important ...

Chemical reactions are the breaking and forming of chemical bonds, which are fundamental to the creation of new technologies. Inevitably, discovering and developing new chemical reactions is a ...

Crystallographic studies of D-xylose isomerase (D-xylose ketol-isomerase, EC 5.3.1.5) incubated to equilibrium with substrate/product mixtures of xylose and xylulose show electron density for a bound ...

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") ...

Putting a new twist on an old favorite of organic chemistry, researchers have unveiled the phospha-bora-Wittig reaction. It offers a relatively straightforward way to prepare phosphaalkenes, which are ...

Electrocatalysis underlies hydrogen production, fuel cells, and carbon-neutral chemical synthesis, which enables next-generation clean-energy systems ...

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 ...

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 ...
