(Phys.org) -- When creating nanomaterials, cracking is generally considered a problem; it usually means something has gone wrong and the result, as with other material making processes such as glass or ceramics, almost always ...
Smart phones have shiny flat AMOLED displays. Behind each single pixel of these displays hide at least two silicon transistors which were mass-manufactured using laser annealing technologies. While the traditional methods ...
