New research from physicists at the University of Sussex will ‘significantly advance’ the new technology area of liquid electronics, enhancing the functionality and sustainability of potential applications in printed electronics, wearable health monitors and even batteries.

In their research paper published in ACS Nano, the Sussex scientists have built on their previous work to wrap emulsion droplets with graphene and other 2D materials by reducing the coatings down to atomically-thin nanosheet layers. In doing so they were able to create electrically-conducting liquid emulsions that are the lowest-loading graphene networks ever reported — just 0.001 vol%.

This means that ...

A research team led by Lund University in Sweden has shown how solar power can convert carbon dioxide into fuel, by using advanced materials and ultra-fast laser spectroscopy. The breakthrough could be an important piece of the puzzle in reducing the levels of greenhouse gases in the atmosphere in the future. The study is published in Nature Communications.

The sunlight that hits Earth during one hour corresponds roughly to humanity’s total energy consumption for an entire year. Our global carbon dioxide emissions are also increasing. Using the sun’s energy to capture greenhouse gases and converting it into fuel or another useful chemical, is a research focus for many today...

Rice lab’s RAMBO reveals unexpected influence on compound’s crystal lattice.
Phonons are collective atomic vibrations, or quasiparticles, that act as the main heat carriers in a crystal lattice. Under certain circumstances, their properties can be modified by electric fields or light. But until now, nobody noticed they can respond to magnetic fields as well.

That may be because it takes a powerful magnet.
