Nanoparticle dyes boost storage The idea of storing data in fluorescent dyes has been around for a while, and researchers have been trying to boost storage capacity by recording multiple bits of information in a single spot using several types of dye. A new solution to this problem uses layered nanoparticles. mark for My Articles similar articles

Virtual molds cast colloid Blue Mosque A way to direct colloids to self-assemble in an almost infinite variety of configurations has been devised. The technique relies on the creation of a pre-determined pattern of magnetic fields to generate a 'virtual mold' to dictate the final position of the particles. mark for My Articles similar articles
