Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This ...

Light microscopes have revolutionized our understanding of the microcosmos, but their resolution is limited to about 100 nanometers. To see how molecules bond, break, or change their structure, we ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

When light hits certain molecules, it dislodges electrons that then move from one location to another, creating areas of positive and negative charge. This 'charge transfer' is highly important in ...

What is Atom Probe Tomography? Atom Probe Tomography (APT) is a powerful analytical technique that provides three-dimensional (3D) imaging and chemical composition analysis of materials at the atomic ...

Researchers have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily synthetically accessible from alpha ...

A new method of molecular manipulation is being developed that allows scientists to make one-atom changes within a day and without the need to rebuild the molecule. The goal is to accelerate the drug ...
