One-dimensional quantum materials can deliver record-high current densities

Thu, 04/19/2018 - 14:51
The advent of graphene resulted in a massive, world-wide, effort directed at investigation of other two-dimensional (2D) layered materials. One-dimensional (1D) bundled materials have received considerably less attention. Similar to the 2D layered materials with covalently bonded layers separated by the van der Waals gaps, the 1D materials consist of covalently bonded one-dimensional wires with van der Waals gaps between the wires. Researchers now have discovered that quasi-1D nanoribbons reveal an exceptionally high current density at the peak of the stressing DC current. This level of the current density exceeds that in any conventional metals like copper by almost two orders of magnitude.

Nanotechnology takes steps towards artificial retinas

Wed, 04/18/2018 - 11:19
Sensory substitution with flexible electronics is one of the intriguing fields of research that takes place in nanotechnology labs around the world. In line with this focus on human senses, in the future artificial retinas integrated with the human body may not only repair damaged vision but also expand it to see a wider range wavelengths (e.g. ultraviolet light). Researchers now have demonstrated a new self-powered brain-linked vision electronic skin (e-skin) for mimicking the human retina. The general idea of our device design of brain-linked vision electronic skin is constructing an integrated flexible system including photodetector array, information analyzer, signal transmitter, and electricity power unit.
