APIs in the design of multi-component functional solids are shown.

A copper tetramer catalyst created by researchers at Argonne National Laboratory may help capture and convert carbon dioxide in a way that ultimately saves energy. It consists of small clusters of four copper atoms each, supported on a thin film of aluminum oxide. These catalysts work by binding to carbon dioxide molecules, orienting them in a way that is ideal for chemical reactions. The structure of the copper tetramer is such that most of its binding sites are open, which means it can attach more strongly to carbon dioxide and can better accelerate the conversion.

In most ultracold Bose-Einstein Condensates (BEC), the quantum gas (yellow peak) is accompanied by normal gas jiggling with thermal noise (the blue hump below the peak). As the noise or entropy is decreased, however, the jiggling disappears to leave an almost pure quantum gas. Ryan Olf graphic.

Microtubules are hollow cylinders with walls made up of tubulin proteins -- alpha (green) and beta (blue) -- plus EB proteins (orange) that can either stabilize or destabilize the structure of the tubulin proteins.

This artist's concept shows the silhouette of a rocky planet, dubbed HD 219134b. At 21 light-years away, the planet is the closest outside of our solar system that can be seen crossing, or transiting, its star.

Schematic illustration of the experiment. An initial density modualtion is imprinted onto the ultracold atoms held in the optical lattice potential (1). Without any disorder, the density modulation is washed out completely in the ensuing dynamics, indicating relaxation towards a thermal equilibrium state (2). In the presence of sufficiently strong disorder, the researchers find that even for long evolution times the system retains memory of the initial state, indicating a non-thermal state in which the system remains stuck (3).
