Supercapacitors turbocharged by laxatives
Supercapacitors turbocharged by laxatives
An international team of scientists, including a professor of chemistry from the University of Bristol, has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents chemically related to laxatives. Their paper, published today , explains why these detergents, called ionic liquids, are better electrolytes than current materials and can improve supercapacitors.

Five cool things our surface scientists do
Surface science can make a big difference to our health, well-being and environment. Our surface scientists at Durham have been working on a whole range of applications that have already changed our lives in some way (think mobile phones and puddles) and could make a real difference to people around the world, particularly in developing countries.

New technique could brighten screens and make smartphone batteries last longer
Our future TV and smartphone screens could have double the energy efficiency, thanks to a technique invented by Imperial scientists. The pixels in many modern screens for TVs, smartphones, tablets, and laptops are lit by little devices called OLEDs (organic light emitting diodes). The findings could make screens of all kinds brighter, with better contrast and longer life.

Experts develop nanolasers on silicon
Researchers at Cardiff University have shown tiny light-emitting nanolasers less than a tenth of the size of the width of a human hair can be integrated into silicon chip design. The photonic band-edge lasers can operate at superfast speeds and have the potential to help the global electronics industry deliver a range of new applications - from optical computing to remote sensing and heat seeking, Professor Diana Huffaker is Scientific Director of Cardiff University's Institute for Compound Semiconductors , based at Cardiff University's School of Physics and Astronomy.

Washable, wearable battery-like devices could be woven directly into clothes
Washable, wearable battery-like devices could be woven directly into clothes
Researchers have developed washable, wearable 'batteries' based on cheap, safe and environmentally friendly inks and woven directly into fabrics. The devices could be used for flexible circuits, healthcare monitoring, energy conversion, and other applications. The team, led by Dr Felice Torrisi , who recently joined Imperial from the University of Cambridge, have shown how graphene - an atom-thick sheet of carbon - and other related materials can be directly incorporated into fabrics.

Wonder material: individual 2D phosphorene nanoribbons made for the first time
Wonder material: individual 2D phosphorene nanoribbons made for the first time
Tiny, individual, flexible ribbons of crystalline phosphorus have been made and measured an international collaboration, in a world first, and they could revolutionise electronics and fast-charging battery technology. Since the isolation of 2-dimensional phosphorene (the phosphorus equivalent of graphene) in 2014, more than 100 theoretical studies have predicted that new and exciting and properties could emerge by producing narrow ‘ribbons' of this material.

Solar-powered supercapacitors could create flexible, wearable electronics
A breakthrough in energy storage technology could bring a new generation of flexible electronic devices to life, including solar-powered prosthetics for amputees. In a new paper published in the journal Advanced Science , a team of engineers from the University of Glasgow discuss how they have used layers of graphene and polyurethane to create a flexible supercapacitor which can generate power from the sun and store excess energy for later use.

What does it take to make a better battery?
What does it take to make a better battery?
Cambridge researchers are working to solve one of technology's biggest puzzles: how to build next-generation batteries that could power a green revolution. A better battery could make all the difference. So what's holding up progress? Like many of us, when I wake up I reach for the phone on my bedside table and begin scrolling through Twitter, Instagram, email and news apps.

Smart fabrics made possible by new metal deposition technique
Smart fabrics made possible by new metal deposition technique
Researchers have devised a way to deposit metals onto fabrics and used it to insert sensors and batteries into these materials. A multidisciplinary team of researchers from Imperial College London led by Dr Firat Güder from the Department of Bioengineering have developed an innovative technique to print metals such as silver, gold and platinum onto natural fabrics.
