Fluid-filled pores separate materials with fine precision (w/video)

New path to separation responds selectively to a flow of multiple materials, precisely separating liquids, gases and solids without clogging and with significant energy savings.

In the heat of the reaction, a single atom delivers

Converting carbon monoxide in fuel cells with a gold catalyst hinges on one ion shuttling the critical electron.

Elasticity of nanoparticles influences their biological function

Researchers have decoupled the tandem effects of shape and elasticity and assessed the role of elasticity on circulation and targeting for small spherical nanoparticles.

Carbon nanospheres reduce engine friction as oil additive

Tiny, perfectly smooth carbon spheres added to motor oil have been shown to reduce friction and wear typically seen in engines by as much as 25 percent, suggesting a similar enhancement in fuel economy.

Medical nanoparticles for the local treatment of lung cancer

Researchers have developed nanocarriers that site-selectively release medicines/drugs at the tumor site in human and mouse lungs. The scientists report that this approach led to a significant increase in the effectiveness of current cancer medicines in lung tumour tissue.

Breakthrough in nonlinear optics research

A method to selectively enhance or inhibit optical nonlinearities in a chip-scale device has been developed by scientists.

Semiconductor technology could make night vision, thermal imaging affordable

Semiconductors made in CMOS technology reach nearly 10 terahertz.
