Researchers have developed a way to make these structures grow in an electron microscope. By recording the atoms self-assembling to form the whiskers - renamed in modern fashion as nanowires - they hope to understand how they grow and how to tune the growth conditions to build nano-devices.

Scientists have been making nanoparticles for more than two decades in two-dimensional sheets, three-dimensional crystals and random clusters. But they have never been able to get a sheet of nanoparticles to curve or fold into a complex three-dimensional structure. Now researchers have found a simple way to do exactly that.

Researchers have developed a transparent electrode with high electrical conductivity for solar cells and other optoelectronic components - that uses minimal amounts of material. It consists of a random network of silver nanowires that is coated with aluminium-doped zinc oxide. The novel electrode requires about 70 times less silver than conventional silver grid electrodes, but possesses comparable electrical conductivity.
