A new twist on electrosprays

Saturn-shaped drops generate millions of microscopic, uniform particles.

Novel thermal ablation system for transdermal drug delivery

Researchers used a combination of transparent gel patches, gold nanorods, and near-infrared light to create a unique thermal ablation system for transdermal drug delivery.

Reality check for topological insulators

So far, topological insulators have not quite lived up to the expectations fueled by theoretical studies. Physicists now have an idea bout why.

Reusable, carbon nanotube-reinforced filters clean toxins from water

Carbon nanotubes immobilized in a tuft of quartz fiber have the power to remove toxic heavy metals from water.

Physicists turn a crystal into an electrical circuit

Transparent, 3-D electronics can be configured and erased like an Etch A Sketch.

Living computers: RNA circuits transform cells into nanodevices (w/video)

New research demonstrates how living cells can be induced to carry out computations in the manner of tiny robots or computers.

Physicists design ultrafocused pulses

Physicists have devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

High-speed FM-AFM and simulation reveal atomistic dissolution processes of calcite in water

Recently, the dissolution mechamism of calcite attracts much attention because of its importance in geologic carbon sequestration technology to capture carbon dioxide from the air and to store it underground.
