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.
A University of Arkansas physicist and his colleagues have found that ultra-thin films of superconductors and related materials don't lose their fundamental properties when built under strain when built as atomically thin layers, an important step towards achieving artificially designed room temperature superconductivity. This ability will allow researchers to create new types of materials and properties and enable exotic electronic phases in ultra-thin films.
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.
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.
In solid materials with regular atomic structures, figuring out weak points where the material will break under stress is relatively easy. But for disordered solids, like glass or sand, their disordered nature makes such predictions much more daunting tasks. Now, a collaboration combining a theoretical model with a first-of-its kind experiment has demonstrated a novel method for identifying "soft spots" in such materials.
The technology in 'fire paint' used to protect steel beams in buildings and other structures has found a new life as a first-of-its-kind flame retardant for children's cotton sleepwear, terrycloth bathrobes and other apparel.
Much like a meteor impacting a planet, highly charged ions hit really hard and can do a lot of damage, albeit on a much smaller scale. And much like geologists determine the size and speed of the meteor by looking at the hole it left, physicists can learn a lot about a highly charged ion's energy by looking at the divots it makes in thin films.
