Artificial cells, or liposomes, are a promising area in biotechnology and nanotechnology, and now they have a new power source. An experimental finding has revealed a new method for converting light to stored chemical energy within the cells.
A team headed by Arizona State University chemistry professors Thomas Moore and Devens Gust has developed a light-powered molecular pump that shuttles calcium ions through a phospholipid membrane – calcium ion pumping that resembles various key cellular activities in living organisms, but engineered to be powered by light through specially designed molecules.
The research is reported in the November 28 issue of the journal Nature by Ira M. Bennett, Hebe M. Vanegas Farfano, Federica Bogani, Alex Primak, Paul A. Liddell, Ana L. Moore, Thomas A. Moore and Gust from Arizona State University and Luis Otero, Leonides Sereno and Juana J. Silber from Universidad National de Rio Cuarto in Argentina.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
