Harvesting hydrogen from nanogardens

Easily produced, nature-like nanostructures of cobalt phosphide are highly effective catalysts for the electrolysis of water, according to research performed by chemist Ning Yan and his team at the University of Amsterdam's ...

Enhancing the performance of solar cells with 'graphene armor'

A team of researchers, affiliated with UNIST has come up with a novel electrode that could greatly improve the stability of perovskite solar cells (PSCs), the most promising candidate for the next generation solar cells due ...

The lightest electromagnetic shielding material in the world

Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic components or the transmission of signals. High-frequency electromagnetic ...

Magnonic nano-fibers opens the way towards new type of computers

Magnetism offers new ways to create more powerful and energy-efficient computers, but the realization of magnetic computing on the nanoscale is a challenging task. A critical advancement in the field of ultralow power computation ...

Building better electron sources with graphene

Photocathodes that produce electron beams for electron microscopes and advanced accelerators can be refreshed and rebuilt repeatedly without opening the devices that rely on them, provided the electron emitting materials ...

New chemistry for ultra-thin gas sensors

The application of zinc oxide layers in industry is manifold and ranges from the protection of degradable goods to the detection of toxic nitrogen oxide gas. Such layers can be deposited by atomic layer deposition (ALD) which ...

Iron chemistry yields surprisingly effective catalyst

As every junkyard vehicle amply shows, iron is prone to rust into iron oxide. But this very reactivity also makes iron and its compounds useful tools for reinventing chemical transformations.

Buzzing to rebuild broken bone

Healing broken bones could get easier with a device that provides both a scaffold for the bone to grow on and electrical stimulation to urge it forward, UConn engineers reported on June 27 in the Journal of Nano Energy.
