Electrospray ionization (ESI) is best known as a way to introduce chemical compounds and mixtures into mass spectrometers. The machines apply a voltage to a stream of liquid containing a sample, ...
The reaction generates amino acids and nucleic acids, the building blocks of proteins and DNA. Four billion years ago, the Earth looked very different than it does today, devoid of life and covered by ...
When chemists design new chemical reactions, one useful piece of information involves the reaction's transition state—the point of no return from which a reaction must proceed. This information allows ...
