Honeycomb Nets from Bismuth Cubes: A New Prospect for Nanoelectronics

Researchers from Dresden discover a new material that conducts electric currents without loss of power over its edges and remains an insulator in its interior. The material is made out of bismuth cubes packed in a honeycomb motif that is known from the graphene structure. As opposed to graphene, the new material exhibits its peculiar electrical property also at room temperature and, hence, holds big promises for applications in nanoelectronics.

Graphen für verbesserten Flammschutz von Kunststoffen

Durch Zusatz von lediglich 0,5 bis zwei Prozent des Kohlenstoffmoleküls Graphen gelang es, den Flammschutz von Kunststoffen zu optimieren. Damit erweise sich das nur aus einer oder wenigen Atomlagen bestehende Graphen als ein vielversprechender neuer Hilfsstoff für einen halogenfreien Flammschutz von Kunststoffen

Scientists engineer artificial human liver for drug testing and discovery

IBN researchers have now made it possible for companies to predict the toxicity of new drugs earlier, potentially speeding up the drug development process and reducing the cost of manufacturing. The tool they have engineered to enable this is an artificial human liver piece, which mimics the natural tissue environment closely.
