Hard carbon nanofiber aerogel becomes superelastic

Conductive and compressible carbon aerogels are useful in a variety of applications. In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. ...

Mixed-cation perovskite solar cells in space

With the continuous improvement of efficiency and stability, perovskite solar cells are gradually approaching practical applications. PSCs may show the special application in space where oxygen and moisture (two major stressors ...

Physicists develop concept of new fast non-volatile memory

Using micromagnetic simulation, scientists have found the magnetic parameters and operating modes for the experimental implementation of a fast racetrack memory module that runs on spin current, carrying information via skyrmionium, ...

Financial giants can have a pivotal role for climate stability

Financial institutions, such as banks and pension funds, have a key role to play in efforts to avoid dangerous climate change. And it is not only about redirecting investments to renewable energy and low-carbon businesses, ...

Making batteries from thin air

Sunlight is being used to convert carbon dioxide into batteries, thanks to a new technology being developed by researchers at the University of Newcastle.

S, N co-doped carbon nanotube-encapsulated CoS2@Co

Electrochemical water splitting is favorable strategy to produce high-purity H2. The current mainstream catalysts for water electrolysis are precious metals (Pt, RuO2, IrO2), which possess superior catalytic activity, relatively ...
