If the bristles of a brush abruptly collapsed into wads of noodles, the brush would, of course, become useless. When it's a micron-scale brush called a "polyelectrolyte brush," that collapse can put a promising experimental drug or lubricant out of commission.
Researchers at Columbia Engineering, experts at manipulating matter at the nanoscale, have made an important breakthrough in physics and materials science, recently reported in Nature Nanotechnology. Working with colleagues from Princeton and Purdue Universities and Istituto Italiano di Tecnologia, the team has engineered "artificial graphene" by r […]
Scientists were already excited to learn this summer that New Horizons' next flyby target – a Kuiper Belt object a billion miles past Pluto – might be either peanut-shaped or even two objects orbiting one another. Now new data hints that 2014 MU69 might have company: a small moon.
