How nanoparticles give electrons away

Researchers gain new insights into the electrical charge of platinum particles.

Isolating water's impact on vibrations within DNA

To isolate the contribution of water to the vibrational fluctuations that occur between DNA, bulk water, and the charged biomolecular interface between the two, researchers have performed two-dimensional spectroscopic analyses on double-stranded DNA helices at different hydration levels.

New microscope creates near-real-time videos of nanoscale processes (w/video)

Engineers have designed an atomic force microscope that scans images 2,000 times faster than existing commercial models. With this new high-speed instrument, the team produced images of chemical processes taking place at the nanoscale, at a rate that is close to real-time video.

Doped organic semiconductors explored

Until now, little was known about how the doping molecules are integrated into the chemical structure of organic semiconductors. New research has found that they consist of a matrix of undoped crystallites in which such 'mixed crystallites' are embedded. It is this very species that takes over the role as the actually doping molecule.

Nanoscale one-way street for light

An optical device at nanoscale which allows light to pass in only one direction has been developed by researchers. It consists of alkali atoms which are coupled to ultrathin glass fibres.

The artificial materials that came in from the cold

Researchers develop nature-mimicking freeze-casting technique for fabricating advanced porous materials.

Diagnostics with birefringence

A new rapid test can detect not only malaria parasites but also viruses such as HIV or Ebola, diverse bacteria or biomarkers, like glucose or cholesterol.
