Chemi-ionization reactions involve the formation of ionic products through the transfer of electrons during collisions between excited and ground-state species. These processes, which can occur in ...

Proton transfer is ubiquitous in chemistry and biology, occurring, for example, in proteins, enzyme reactions and across proton channels and pumps. However, it has always been described in the context ...

As part of “From Sample to Verdict,” LCGC International sat down with Ed Sisco and Sarah Shuda, Research Chemists at NIST, to discuss the work that their groups are conducting that are helping to ...

Mass spectrometry (MS) is already perhaps the most popular analytical chemistry tool in drug discovery and development. Its use is ubiquitous in bioanalytical laboratories for drug and metabolite ...

Studies in Conservation aims to be the premier international peer-reviewed journal for the conservation of historic and artistic works. The intended readership includes practising conservators of all ...

Sensitive and quick detection of airborne molecular contaminants (AMCs) in semiconductor fabrication facilities is crucial to the quality and efficiency of production. Fabs have the potential to host ...
