A nano-scale solar cell inspired by the coaxial cable offers greater efficiency than any previously designed nanotech thin film solar cell by resolving the 'thick and thin' challenge inherent to capturing light and extracting current for solar power.
Developed by Pitt engineering professor Di Gao in response to the 'Deepwater Horizon' oil leak, the technique combines an ordinary cotton filter with a solution that repels oil while allowing water to pass through.
In 2010 several hundreds of millions of Euros will be available for funding innovative projects in the chemical industry for instance in FP7 NMP (Nano-Materials-Production) with topics such as modelling and control of intensified process systems for chemical and biotechnological processes and new materials for new energy efficient building components or lighter vehicles.
Scientists at the Universidad Carlos III of Madrid (UC3M) have proven the validity of tomographic representation of quantum states, which can help quantum technologies transmit information more safely and efficiently.
In previous experiments the photons were confined to fiber channels a few hundred meters long to ensure their state remained unchanged, but in the new experiments pairs of photons were entangled and then the higher-energy photon of the pair was sent through a free space channel 16 km long.
The results of the study show that these clusters of small numbers of silver atoms catalyze ethanol oxidation at similar concentrations to those found in the blood of alcoholics and at values of membrane potential and pH that are compatible with those exhibited by mammalian cells.
Physicists at the Technische Universitaet Muenchen (TUM) are gearing up for experimental tests of findings they arrived at through theoretical considerations: that electrochemical reactions take place more rapidly on isolated, nanometer-scale electrodes than on their familiar macroscopic counterparts, and that this surprising behavior is caused by thermal noise.
Imec and Holst Centre have developed very sensitive integrated sensing elements for gas detection. The polymer-coated microbridges in high-density arrays can detect ppm-level concentrations of vapors using on-chip integrated read-out techniques.
Researchers pinpointed noncarbon atoms that create defects when graphene is produced through a technique called graphene-oxide reduction. The researchers also propose how to make that technique more efficient by precisely applying hydrogen - rather than heat - to remove the impurities.
Three-dimensional imaging is dramatically expanding the ability of researchers to examine biological specimens, enabling a peek into their internal structures. And recent advances in X-ray diffraction methods have helped extend the limit of this approach.
Nanotechnology promises employment, sustainability and health. The Dutch government invests heavily in it. But how do we achieve these promises? In preparation for a parliamentary debate about nanotechnology on 21 April 2010, the Rathenau Institute initiated a working visit of MPs to one of the most promising areas of its application: healthcare.
