Scientists have developed a method using DNA origami to turn one-dimensional nano materials into two dimensions. Their breakthrough offers the potential to enhance fiber optics and electronic devices by reducing their size and increasing their speed.
Thermal systems use heat to produce cold, and vice versa. To do so, a material is needed that can dissipate water vapor particularly well and quickly. A new method simply applies this property as a layer onto the components.
A new study reports the first preclinical tests for a novel anti-cancer technology called 'quadrapeutics' that converts current clinical treatments to instantaneously detect and kill only cancer cells. Quadrapeutics combines clinically available drugs, colloidal gold, pulsed lasers and radiation in a novel and safe micro-treatment that improved standard therapy by 17-fold against aggressive, drug-resistant tumors.
Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating atomic arrangements is difficult in conventional materials. Now, researchers at the University of Vienna have directly imaged the diffusion of a butterfly-shaped atomic defect in graphene, the recently discovered two-dimensional wonder material, over long image sequences.
