'Dancing' holes in droplets submerged in water-ethanol mixtures
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.Source: https://www.sciencedaily.com/releases/2018/06/180630153738.htm
Simple logic for nanofluidic computing simulated
Invigorating the idea of computers based on fluids instead of silicon, researchers have shown how computational logic operations could be performed in a liquid medium by simulating the trapping of ions (charged atoms) in graphene (a sheet of carbon atoms) floating in saline solution. The scheme might also be used in applications such as water filtration, energy storage or sensor technology.Source: https://www.sciencedaily.com/releases/2018/06/180629114708.htm
The culprit of some GaN defects could be nitrogen
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.Source: https://www.sciencedaily.com/releases/2018/06/180629114705.htm
Computing power used to track the spread of cancer
Researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another. This migration of cells can lead to metastatic disease, which causes about 90 percent of cancer deaths from solid tumors -- masses of cells that grow in organs such as the breast, prostate or colon. Understanding the drivers of metastasis could lead to new treatments aimed at blocking the process of cancer spreading through the body.Source: https://www.sciencedaily.com/releases/2018/06/180629114657.htm
Sintering atomically thin materials with ceramics now possible
For the first time, researchers have created a nanocomposite of ceramics and a two-dimensional material, opening the door for new designs of nanocomposites with such applications as solid-state batteries, thermoelectrics, varistors, catalysts, chemical sensors and much more.Source: https://www.sciencedaily.com/releases/2018/06/180629114654.htm
New testing finds synergistic combination leads to toxicity in nanomaterials
A new study finds reason for caution -- a clear emergence of toxicity -- in nanomaterial product formulations, but it also provides an early testing technique that could help the industry continue to move forward.Source: https://www.sciencedaily.com/releases/2018/06/180629102626.htm
Astronomers observe the magnetic field of the remains of supernova 1987A
For the first time, astronomers have directly observed the magnetism in one of astronomy's most studied objects: the remains of Supernova 1987A (SN 1987A), a dying star that appeared in our skies over thirty years ago. In addition to being an impressive observational achievement, the detection provides insight into the early stages of the evolution of supernova remnants and the cosmic magnetism within them.Source: https://www.sciencedaily.com/releases/2018/06/180629102617.htm

New mystery discovered regarding active asteroid phaethon
Based on a new study of how near-Earth asteroid Phaethon reflects light at different angles, astronomers think that its surface may reflect less light than previously thought. This is an exciting mystery for the recently approved DESTINY+ mission to investigate when it flies past Phaethon.Source: https://www.sciencedaily.com/releases/2018/06/180629102557.htm
