UCLA chemists report the discovery of a remarkable new nanoscale phenomenon: An ordinary camera flash causes the instantaneous welding together of nanofibers made of polyaniline, a unique synthetic ...

Graduate student Jiaxing Huang was fooling around with his digital camera in the lab one evening when he made an unexpected discovery. He took a flash photo of a vial of polyaniline nanofibers and ...

As the characteristic dimensions of a material approaches the nanoscale its properties and behaviour can change drastically in comparison with those of its bulk form. Although this fact is well known ...
