When a solar cell absorbs a photon of light, it starts an electronic race against time. Two particles — a negatively charged electron and positively charged ​“hole” — generate electricity if they fully separate.

Making chemicals for industrial processes often requires scientists to use a catalyst — a substance that speeds up a chemical reaction, reducing the amount of energy it takes to make different products.

Mosquitos may have a reputation for being one of the world’s most intractable pests, but they are actually quite tiny and fragile.

The lithium-ion battery has transformed the portable electronics industry and is making inroads into energy storage on the electric grid and electrically powered transportation.

In a new study, researchers from the U.S. Department of Energy’s (DOE) Argonne and Brookhaven National Laboratories observed the formation of two kinds of defects in individual nanowires, which are smaller in diameter than a human hair.

In less than one month, over a hundred college students from across the United States will convene in one of the largest cyber defense competitions in the nation.

Many of us are often told we bear a resemblance to another member of our family — for instance, that we have our mother’s nose or our father’s eyes.

Nitrogen oxides (NOx) are some of the most significant pollutants in our atmosphere — they contribute to the formation of smog, acid rain and ground-level ozone.

Replanting trees after events like last year’s catastrophic Western wildfires not only is critical to forest recovery, but could actually help soils take up more carbon from the atmosphere than if the burned areas were just left idle or cultivated.
