New boron compounds for organic light-emitting diodes

Chemists have developed a new class of organic luminescent materials through the targeted introduction of boron atoms into the molecular structures. The compounds feature an intensive blue fluorescence and are therefore of interest for use in organic light-emitting diodes.

Near absolute zero, molecules may start to exhibit exotic states of matter

Experimental physicists have successfully cooled molecules in a gas of sodium potassium to a temperature of 500 nanokelvins - just a hair above absolute zero. They found that the ultracold molecules were relatively long-lived and stable, resisting reactive collisions with other molecules. The molecules also exhibited very strong dipole moments.

'Nano-raspberries' could bear fruit in fuel cells

Scientists have developed a fast, simple process for making platinum 'nano-raspberries' - microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which is helpful in the design of catalysts.

Physicists develop ultrasensitive nanomechanical biosensor

It can analyze the chemical composition of substances and detect biological objects, such as viral disease markers, which appear when the immune system responds to incurable or hard-to-cure diseases, including HIV, hepatitis, herpes, and many others.

Ultrasensitive magnetoplasmonic sensors with nano-antennas

Systems allowing label-free molecular-level detection are expected to have enormous impact on biochemical sciences. Research focuses on materials and technologies based on exploiting the coupling of light with electronic charge oscillations, the so-called localized surface plasmon resonances, in metallic nanostructured antennas.

Closing in on the phenomenon of superconductivity with a two-dimensional atomic gas

Scientists are using this special gas as a model system to more easily study the largely unknown mechanism of the superfluid phase transition in 2D structures. The researchers hope to gain new insight into the so-called room-temperature superconductor, a hypothetical material that does not require cooling to achieve lossless conduction of electricity.
