One way to harness solar energy is by using solar electricity to split water molecules into oxygen and hydrogen. The hydrogen produced by the process is stored as fuel, in a form that can be used to generate power upon demand. To split water molecules into their component parts, a catalyst is necessary, but the catalytic materials currently used in the process are not efficient enough to make the process practical. Using an innovative chemical strategy developed at the University of Virginia, a team of researchers has produced a new form of catalyst using the elements cobalt and titanium. The new process involves creating active catalytic sites at the atomic level on the surface of titanium oxide nanocrystals, which results in a durable catalytic material.

A team of physicists at the University of Maryland, Baltimore County (UMBC) has provided reliable information about which new materials might have desirable properties for a range of applications and could exist in a stable form in nature. The team used cutting-edge computer modeling techniques to predict the properties of 2D materials that have not yet been made in real life.

Physicists at Princeton University have used a material known as magic-angle twisted bilayer graphene to explore how interacting electrons can give rise to rise to surprising phases of matter. By layering two sheets of graphene on top of each other, with the top layer angled at precisely 1.1 degrees, the Princeton researchers produced topological quantum states of matter, which are intriguing classes of quantum phenomena. Topological quantum states first came to the public's attention in 2016 when three scientists – Princeton's Duncan Haldane, who is Princeton's Thomas D. Jones Professor of Mathematical Physics and Sherman Fairchild University Professor of Physics, together with David Thouless and Michael Kosterlitz – were awarded the Nobel Prize for their work in uncovering the role of topology in electronic materials.

Scientists at Rice University have found that nature’s ubiquitous weak force (Van der Waals) is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems. Without applying any other force, the scientists saw that the silver nanosheets acquired permanent bumps where none existed before.

Researchers at North Carolina State University have developed a new technology, called Artificial Chemist 2.0, that allows users to go from requesting a custom quantum dot to completing the relevant R&D and beginning manufacturing in less than an hour. The technology is completely autonomous and uses artificial intelligence and automated robotic systems to perform multi-step chemical synthesis and analysis.
