Plumbene, graphene's latest cousin, realized on a 'nano water cube'

NanoWerk.com - Fri, 05/24/2019 - 13:02
Scientists have created 'plumbene', a 2D-honeycomb sheet of lead atoms. Plumbene has the largest spin-orbit interaction of any Group 14 elemental 2D material, potentially making it a robust 2D topological insulator in which the Quantum Spin Hall Effect might occur even above room temperature.

Plumbene, graphene's latest cousin, realized on the 'nano water cube'

ScienceDaily.com: Nanotechnology News - Thu, 05/23/2019 - 19:14
Researchers have created 'plumbene,' a 2D-honeycomb sheet of lead atoms. As a surprising by-product, the research group also observed a nanoscale palladium-lead Weaire-Phelan-like bubble structure in the palladium substrate -- like the 'Water Cube' of the 2008 Olympics in Beijing.

Producing electricity at estuaries using light and osmosis

ScienceDaily.com: Nanotechnology News - Thu, 05/23/2019 - 19:13
Researchers are working on a technology to exploit osmotic energy -- a source of power that's naturally available at estuaries, where fresh water comes into contact with seawater. In a laboratory experiment, the team reproduced the real-world conditions that occur where rivers meet the sea (pH and salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production.
