Every chemical reaction faces a barrier: For substances to react with one another, it is first necessary to supply energy. In many cases, this energy barrier is low—such as when striking a match. For ...

The simulation of quantum systems and the development of systems that can perform computations leveraging quantum mechanical effects rely on the ability to arrange atoms in specific patterns with high ...

Physicists captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the 'free-range' particles that until now were predicted but never directly ...

Researchers made a breakthrough in the creation of diamond nanothreads. Led by Samuel Dunning and Timothy Strobel, researchers at Carnegie Science have developed a new technique to create diamond ...

A pencil-shaped ultracold gas of frozen two-level atoms interacting via photon-mediated interactions, with elastic and inelastic components. A continuous laser drive excites the atoms on-resonance.

In addition to throwing and catching atoms, they showed that the atoms could be thrown through another stationary optical trap and weren't affected by other atoms encountered along the way. They also ...

Scientists have revolutionized the way metals are made by using lower and slower heating of alloys to control how atoms self-organize during material manufacturing. The discovery, published in Science ...

Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Methanol is a key starting material for chemical products. Researchers can now produce this precursor from CO2 and hydrogen with high efficiency by using isolated metal atoms as catalysts. (Nanowerk ...
