The kinetics of some chemical reactions has been extensively studied with ensemble-averaged methods 1,2. As for the molecular reaction dynamics, only some simple (few atoms) gas-phase elementary ...

For the first time, scientists have used ultrafast X-ray flashes to take a direct image of a single electron as it moved during a chemical reaction. In the new study, published Aug. 20 in the journal ...

Chemical reactions are responsible for life as well as all the products that we use during our lives. But there are some common misconceptions about reactions, especially that the product of a ...

A team of researchers has discovered a new chemical reaction for producing one of the four nucleotides, or building blocks, needed to build DNA. The reaction includes an unusual first step, or ...

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 you get right down to the atomic scale, things happen much faster than we’re used to. That makes it hard to actually see what happens during chemical reactions, so researchers at Harvard have ...
