Physicists discover material for a more efficient energy storage: Experiment confirms predictions of the University of Luxembourg

Predictions of physicists of the University of Luxembourg recently lead to the discovery of a material with special electric properties which engages the interest of plastics producing industry. Three years ago, physicists from Luxembourg had theoretically predicted the unusual characteristics of a particular composite material. These calculations could now be confirmed by experiment in cooperation with the "Centre de Recherche Paul Pascal" in Bordeaux, France, and resulted in the discovery of a so-called high-k-material, which might enable the production of better energy storage devices - the basis for smaller, faster and more efficient electronics.

The earlier calculations made by the team around Tanja Schilling, professor of physics at the University of Luxembourg, were at first rather bad news for the field of materials research: they indicated that certain compound materials made of polymers and flaky graphene, unlike those made of polymers and carbon nanotubes, did not increase the conductivity of the material to the degree that was generally expected until then. It was a surprising conclusion at the time which questioned the use of graphene in order to increase conductivity.

Heat radiates 10,000 times faster at the nanoscale

When heat travels between two objects that aren't touching, it flows differently at the smallest scales--distances on the order of the diameter of DNA, or 1/50,000 of a human hair.

While researchers have been aware of this for decades, they haven't understood the process. Heat flow often needs to be prevented or harnessed and the lack of an accurate way to predict it represents a bottleneck in nanotechnology development.

The subtle dance of atoms influences enzyme activity: Certain infinitesimal fluctuations of distant atoms can control enzyme function even though they are not directly involved in enzyme catalysis

Infinitesimal fluctuations occurring on the milli- and even nano-second time scales within the three-dimensional structure of enzymes may be one of the keys to explaining protein function. Professor Nicolas Doucet's team at INRS has demonstrated that even when certain amino acids are far from the active site of an enzyme, a change in their flexibility and atomic fluctuations can significantly impact enzyme activity. This phenomenon, which has been underestimated up to now, could explain certain protein engineering failures and help improve the way synthetic functional enzymes are designed.
