Researchers in the United States and China have teamed to develop a speedway for future devices, an exotic type of electrical conductor called a topological insulator (TI). In a new paper in the journal AIP Advances, the international collaborators report that they grew two types of TI materials inside an ultra-high vacuum chamber on both smooth and rough surfaces and then evaluated their abilities to transport electrons.
New work opens the fascinating prospects of single-molecule microscopy and spectroscopy on a smart phone. One can now speculate on the possible applications of such a portable imaging device and on the perspectives it may open in different fields of science and technology.
A breakthrough in photonics that will help create extremely compact optical chips, a hair's width in size and delivering a photon at a time, has been achieved by researchers from the University of Sydney.
Researchers have used an electron microscope to bend, deform and melt the one-molecule-thick glass. These are all things that happen just before glass shatters, and for the first time, the researchers have directly imaged such deformations and the resulting 'dance' of rearranging atoms in silica glass.
Researchers have developed a new model that allows better control of self-assembly, the process through which molecules aggregate by themselves into larger clusters. This model could be used in the production of plastic solar cells, and is an interesting step in the long?term process of developing a synthetic cell.
