It’s a trap!

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.

Nickel in the X-ray limelight

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.
March 26, 2018
Researchers from Argonne and the University of California at Santa Barbara have identified another elemental actor that helps activate palladium while reducing the amount of the precious metal needed for reactions to occur.

The element of surprise

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.
March 14, 2018
In a new study, Argonne and University of Lille chemists explored protactinium’s multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide elements.
