In a marriage of quantum science and solid-state physics, researchers have used magnetic fields to confine groups of electrons to a series of concentric rings within graphene, a single layer of tightly packed carbon atoms.
The existing surface termination technique using hydrogen to stabilize the diamond's structure for application in electronic power devices results in two-dimensional hole gas layers (2DHG). Attempting to remove these layers using oxygen-termination roughens the diamond surface and leads to degradation of the device performance. To overcome this, researchers have removed 2DHG from diamond using water vapor annealing and maintained an atomically flat surface.
Scientists have demonstrated the possibility of developing a new type of anti-neoplastic drugs based on nanoMIPs, or 'plastic antibodies'. NanoMIPs are synthetic polymers that can function as antibodies, selectively binding to target proteins on the surface of cancer cells.
Researchers have developed a simple flame burning method to prepare single-walled carbon nanotube (SWNT) sponges on a large scale. The SWNT sponge has multifunctional properties and can be used in the fields of cleaning-up, sensing and energy storage.
