(Phys.org) —Future transistors made of semiconducting single-walled carbon nanotubes (s-SWNTs) have the potential to perform much better than today's transistors. However, when SWNTs are grown in bulk, only about two-thirds ...
Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used ...
