'Swiss cheese' membrane with adjustable holes

The 'Swiss cheese' structure is characteristic of many polymer membranes and is now modified by introducing iron within the polymer. Using an electric signal or a chemical reaction, the pore size can be adjusted. The key to this is controlled adding or extracting of electrons to and from iron.

Microrockets fueled by water neutralize chemical and biological warfare agents

With fears growing over chemical and biological weapons falling into the wrong hands, scientists are developing microrockets to fight back against these dangerous agents, should the need arise. In a new paper, they describe new spherical micromotors that rapidly neutralize chemical and biological agents and use water as fuel.

New solar power nanotechnology material converts 90 percent of captured light into heat

A multidisciplinary engineering team developed a new nanoparticle-based material for concentrating solar power plants designed to absorb and convert to heat more than 90 percent of the sunlight it captures. The new material can also withstand temperatures greater than 700 degrees Celsius and survive many years outdoors in spite of exposure to air and humidity.
