Coffee chemistry

It’s one of the most popular beverages in the world, and many of us rely on it to stay awake every day. But not every cup of coffee is created equal. From the bean to the brew, science can help you get the perfect cup. The American Chemical Society’s Reactions goes on a quest for better coffee through chemistry.

New material is a scientific oxymoron

Most materials are capable of being only one thing at a time, but a team of engineers and physicists at the University of Wisconsin–Madison have now created an entirely new material in which completely contradictory properties can coexist

Nanoparticle maps reveal best shape for batteries

Many recent big technological advances in computing, communications, energy, and biology have relied on nanoparticles. It can be hard to determine the best nanomaterials for these applications, however, because observing nanoparticles in action requires high spatial resolution in messy, dynamic environments.
