A new way to build nanostructures

The making of three-dimensional nanostructured materials - ones that have distinctive shapes and structures at scales of a few billionths of a meter - has become a fertile area of research, producing materials that are useful for electronics, photonics, phononics and biomedical devices. But the methods of making such materials have been limited in the 3-D complexity they can produce. Now, an MIT team has found a way to produce more complicated structures by using a blend of current "top-down" and "bottom-up" approaches.

Extremely rapid water: Scientists decipher a protein-bound water chain

Researchers from the Ruhr-Universitaet-Bochum (RUB) Department of Biophysics of Prof. Dr. Klaus Gerwert have succeeded in providing evidence that a protein is capable of creating a water molecule chain for a few milliseconds for the directed proton transfer. The combination of vibrational spectroscopy and biomolecular simulations enabled the elucidation of the proton pump mechanism of a cell-membrane protein in atomic detail. The researchers demonstrated that protein-bound water molecules play a decisive role in the function.

Scientists report on a unique 'ubiquitous element strategy' for synthesizing industrially important materials

Japanese scientists report on a unique 'ubiquitous element strategy' for synthesizing industrially important electronic, thermionic, and structural materials using naturally abundant elements. This strategy aims to overcome the 'rare-element crisis' that was triggered by increasing demand for such elements as lithium, used in batteries, and dysprosium for Ne-Fe-B permanent magnets.

Implants of the future: bioactive, corrosion resistant and antibacterial

The interaction of materials with biological tissues and organisms and their adaptation to them play an important role in the development of implants. New developments, including some in the field of nanobiotechnology, are expected to bring improvements. In general, the production of functional implants depends on the adherent layer between the coating and the basic material.
