Tuning chemical reactions with light

The chemical industry consumes a lot of energy, not only to initiate reactions but also to separate products from by-products. In a promising emerging field of research, scientists worldwide are trying to use nanoscale antennas ...

Growing 'metallic wood' to new heights

Natural wood remains a ubiquitous building material because of its high strength-to-density ratio; trees are strong enough to grow hundreds of feet tall but remain light enough to float down a river after being logged.

Tiny bubbles making large impact on medical ultrasound imaging

If you were given "ultrasound" in a word association game, "sound wave" might easily come to mind. But in recent years, a new term has surfaced: bubbles. Those ephemeral, globular shapes are proving useful in improving medical ...

Nanoscale machines convert light into work

Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics ...

Measuring adhesion and friction of polymer nanofibers

Using a device small enough to fit on the head of a pin, researchers at the University of Illinois at Urbana-Champaign gained new knowledge about the properties of polymer fibers at the nanoscale—knowledge that can inform ...
