A team of researchers at Finland's Aalto University has discovered a way to cause droplets of ferrofluid (liquids with suspended magnetic nanoparticles in them) to self-assemble into complex shapes. In their paper published ...
Sometimes water spreads evenly when it hits a surface; sometimes it beads into tiny droplets. While people have noticed these differences since ancient times, a better understanding of these properties, and new ways of controlling ...
