A breakthrough in understanding materials for next-generation electronic devices.
Physicists capture microscopic origins of thinning and thickening fluids
In things thick and thin: Cornell physicists explain how fluids -- such as paint or paste -- behave by observing how micron-sized suspended particles dance in real time. Using high-speed microscopy, the scientists unveil how these particles are responding to fluid flows from shear -- a specific way of stirring.
From a flat mirror, designer light
An optical phenomenon that defies laws of reflection and refraction.
The quantum tunneling effect leads electron transport in porphyrins
A research center of the CSIC participates in a study that refutes the hypothesis that their movement is based on jumps from one region to another. The porphyrins may be used in quantum computing since they keep the wave nature of electrons.

Stefan Hell to receive the 2011 Koerber Prize
The Goettingen-based physicist Stefan Hell has designed high-resolution optical microscopes which can see many times more sharply than was thought possible.
Novel hydrogel-coated mesh is promising material for oil spill clean-ups
In the last couple of years, there has been particularly growing interest worldwide in exploring ways of finding suitable solutions to clean up oil spills and deal with industrial oily wastewater through use of nanomaterials. Key for the success of these materials is a high separation capacity, with resistance to oil fouling, and that are easily recyclable. Oil/water separation is an interfacial challenge, and novel materials designed to possess special wettability have different interaction and affinity for oil and water, thus can realize the separation. Until now, researches in this field all focus on materials with both hydrophobic and oleophilic properties. However, the oil-removing type of materials is easily fouled even blocked up by oils because of their intrinsic oleophilic property. A novel superhydrophilic and underwater superoleophobic hydrogel coated mesh can selectively separate water from oil/water mixtures effectively and without any extra power.
Faster diagnostics through cheap, ultra-portable blood testing

Building chips from collapsing nanopillars
By turning a common problem in chip manufacture into an advantage, MIT researchers produce structures only 30 atoms wide.
A diagnostic biological "computer" network incorporated in human cells
Researchers led by ETH professor Yaakov Benenson and MIT professor Ron Weiss have successfully incorporated a diagnostic biological "computer" network in human cells. This network recognizes certain cancer cells using logic combinations of five cancer-specific molecular factors, triggering cancer cells destruction.
smart forvision: A look at the future of electric mobility
smart has always been a pioneer in matters of urban mobility and with the smart fortwo electric drive the company is showing the direction of development in cities around the world. Together with BASF, the largest automotive supplier in the chemical industry, smart is demonstrating its leading role in the use of forward-looking technologies above and beyond the drive system. The joint concept vehicle smart forvision presented at the 2011 International Motor Show in Frankfurt combines a futuristic design with technologies relating to energy efficiency, lightweight design and temperature management.
Help for nanoscale materials research
If nanoparticles are incorporated into a material with the aim of imparting new functions, the properties of the single nanoparticles have to be precisely characterized. To date this information was only available for individual nanoparticles that are smaller than 500 nanometres. Now, the refinement of a procedure used in biology to study cell membranes has shed light onto even smaller 'dwarves'.
Iron ‘veins’ are secret of promising new hydrogen storage material
With a nod to biology, scientists at the National Institute of Standards and Technology (NIST) have a new approach to the problem of safely storing hydrogen in future fuel-cell-powered cars. Their idea: molecular scale 'veins' of iron permeating grains of magnesium like a network of capillaries.
Better solar cells around the corner
Design optimization could help maximize the power conversion efficiency of thin-film silicon solar cells.
