'Dancing' holes in droplets submerged in water-ethanol mixtures

ScienceDaily.com: Nanotechnology News - 30 июня, 2018 - 22:37
Researchers have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This curious, complex phenomenon is driven by an interplay between how ionic liquids dissolve, and how the boundary around the droplet fluctuates. Self-driven motion is a key feature of active matter, materials that use ambient energy to self-propel, with potential applications to drug delivery and nano-machine propulsion.

The culprit of some GaN defects could be nitrogen

ScienceDaily.com: Nanotechnology News - 29 июня, 2018 - 18:47
As silicon-based semiconductors reach performance limits, gallium nitride is becoming the next go-to material for several technologies. Holding GaN back, however, is its high numbers of defects. Better understanding how GaN defects form at the atomic level could improve the performance of the devices made using this material. Researchers have taken a significant step by examining and determining six core configurations of the GaN lattice.
