Many materials store information about what has happened to them in a sort of material memory, like wrinkles on a once crumpled piece of paper. Now, a team of physicists has uncovered how, under specific conditions, some materials seemingly violate underlying mathematics to store memories about the sequence of previous deformations.

A new technique to trap clusters of platinum atoms in nanoscale islands could lead to more efficient catalysts for the chemical industry.

Turning environmental waste into useful chemical resources could solve many of the inevitable challenges of our growing amounts of discarded plastics, paper and food waste, according to new research.

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water.

This startling mechanism for promoting depolymerization relies on an additive that many plastics already contain: a pigment called carbon black that gives plastic its black color. Through a process called photothermal conversion, intense light is focused on plastic containing the pigment to jumpstart the degradation. The lab’s method has since been tried out on such

How can the latest technology, such as solar cells, be improved? An international research team is helping to find answers to questions like this with a new technique. For the first time, the formation of tiny, difficult-to-detect particles — known as dark excitons — can be tracked precisely in time and space. These invisible carriers

Scientists have developed a new method for measuring temperature extremely accurately by using giant ‘Rydberg’ atoms. This atomic thermometer provides accurate measurements ‘out of the box,’ without needing initial factory adjustments, because it relies on the basic principles of quantum physics. By using Rydberg atoms’ sensitivity to environmental changes, this technique could simplify temperature sensing

AI agents trained in simulations that differ from the environments where they are deployed sometimes perform better than agents trained and deployed in the same environment, research shows.

Researchers present a solution to the challenging problem of recycling poly-cotton textile waste. The process starts with fully removing all cotton from the fabric using superconcentrated hydrochloric acid at room temperature. The cotton is converted into glucose, which can be used as a feedstock for biobased products such as renewable plastics. The remaining polyester fibers

The narrow, deep holes required for one type of flash memory are made twice as fast with the right recipe, which includes a plasma made from hydrogen fluoride.
