Freestanding borophene synthesized for the first time

14 мая, 2019 - 09:17
Borophene, the atomically flat form of boron, differs from graphene and other two-dimensional (2D) materials in an important way: It can't be reduced from a larger natural form because bulk boron is not naturally layered. While graphite is composed of stacks of atomically thin sheets that can be peeled off one at a time to make graphene, there is no such analogous process for making 2D boron. Or so researchers had thought. Now, however, researchers have synthesized free-standing borophene for the first time and in a scalable manner.

Energy from seawater enabled by metal-organic frameworks

13 мая, 2019 - 18:15
A new, inexpensive system for the direct electrochemical extraction of energy from seawater offers the advantage of also being able to handle short spikes in power demand, while maintaining longer term steady power. To do so, the system can autonomously switch between two modes of operation.

Superlubricity and nanotechnology

10 мая, 2019 - 13:19
Superlubricity is a phenomenon where two surfaces slide over each other with barely any resistance (a state that is called near-zero friction). This is a very special case where friction almost vanishes between two surfaces. The difficulty of achieving superlubricity in mechanical systems is due to the very complex physical, chemical, and mechanical interactions that occur simultaneously at the sliding interfaces of these systems. Superlubricity is one of the most promising properties of functional nanomaterials for energy saving applications.

Graphite film coating makes perovskite solar cells waterproof

10 мая, 2019 - 10:43
Researchers tested the waterproofing by submerging the coated perovskite cells in water and using the harvested solar energy to split water into hydrogen and oxygen. The coated cells worked underwater for 30 hours - ten hours longer than the previous record.
