(Phys.org)—Researchers from Kyoto University have, for the first time, isolated a water dimer. Using a technique known as molecular surgery, they encapsulated the dimer within a fullerene-C70 molecule. Their work appears ...
In the nanoworld, tiny particles of gold can operate like snow blowers, churning through surface layers of an important class of semiconductors to dig unerringly straight paths. The surprising trenching capability, reported ...
