“Fluoride batteries can have a higher energy density, which means that they may last longer – up to eight times longer than batteries in use today,” says study co-author Robert Grubbs, Caltech’s Victor and Elizabeth Atkins Professor of Chemistry and a winner of the 2005 Nobel Prize in Chemistry. “But fluoride can be challenging to work with, in particular because it’s so corrosive and reactive.”

Fluoride-based batteries have the potential to last up to 8X longer than those in use today. Imagine not having to charge your phone or laptop for weeks...

A new organic polymer blend allows plastic electronics to function in high temperatures without sacrificing performance. This new plastic material could reliably conduct electricity in up to 220 degrees Celsius (428 F), according to a paper published Thursday in the journal Science.

“Commercial electronics operate between minus 40 and 85 degrees Celsius. Beyond this range, they’re going to malfunction,” said Jianguo Mei, a professor of organic chemistry at Purdue University. “We created a material that can operate at high temperatures by blending two polymers together.”

One of these is a semiconductor, which can conduct electricity, and...

Graphene unlocks new potential for ‘smart textiles.’

An international team of scientists, led by Professor Monica Craciun from the University of Exeter Engineering department, has pioneered a new technique to create fully electronic fibres that can be incorporated into the production of everyday clothing. Currently, wearable electronics are achieved by essentially gluing devices to fabrics, which can mean they are too rigid and susceptible to malfunctioning.

The new research instead integrates the electronic devices into the fabric of the material, by coating electronic fibres with light-weight, durable components that will allow images to be shown directly on the fabric.

The research team believe that the discovery could revolutionise the creation of wearable elect...

Force Push is a novel VR technique that allows users to move objects with unprecedented nuance.

The VR interface responds to device-free nuanced hand movements. Force Push provides a more physical, nuanced experience than traditional hand controllers allow in VR. It responds to the speed and magnitude of hand gestures to accelerate or decelerate objects in a way that users can understand intuitively.

Fans of the Star Wars franchise will have to wait more than a year from now to get their fix of Jedi-laden telekinetic spectacles on the big screen. The as-of-yet-to-be-titled Episode IX, the last installment of the space saga as was envisioned in 1977, won’t be released until December 2019...
