Artificial fog helps lasers shine brighter
Artificial fog helps lasers shine brighter
Laser-based lights could replace lightbulbs thanks to an artificial 'fog' that scatters laser light, producing high brightness at low power. The new and improved laser-based lights could be used anywhere from indoor lighting and projectors to car headlights and outdoor floodlights. As they produce high brightness at low power, they would be more energy-efficient than regular lightbulbs or LEDs.

Way to extract colour from black
Scientists have developed a way of extracting a richer palette of colours from the available spectrum by harnessing disordered patterns inspired by nature that would typically be seen as black. Colours that we see in nature often come from nanoscale patterns that reflect light back in particular ways.

Bacteria killed by new light-activated coating
A new coating that activates in low intensity light to kill bacteria such as Staphylococcus aureus and Escherichia coli has been developed by a UCL-led team of researchers. To stop the spread of disease, it could be used to coat phone screens and keyboards, as well as the inside of catheters and breathing tubes, which are a major source of healthcare-associated infections (HCAIs).

New tools show a way forward for large-scale storage of renewable energy
A technique based on the principles of MRI and NMR has allowed researchers to observe not only how next-generation batteries for large-scale energy storage work, but also how they fail, which will assist in the development of strategies to extend battery lifetimes in support of the transition to a zero-carbon future.

Fast-charging, long-running, bendy energy storage breakthrough
A new bendable supercapacitor made from graphene, which charges quickly and safely stores a record-high level of energy for use over a long period, has been developed and demonstrated by UCL and Chinese Academy of Sciences researchers. While at the proof-of-concept stage, it shows enormous potential as a portable power supply in several practical applications including electric vehicles, phones and wearable technology.

Scientists create ’Chemical gardens’ that can be used as bone substitute materials
A new way of making bone-replacement materials that allows for cells to grow around and inside them has been developed by researchers at the University of Birmingham. The team adopted a novel approach called chemobrionics, in which chemical components are controllably driven to react together in specific ways, enabling the self-assembly of intricate bio-inspired structures.

Smart design of new materials could improve energy storage technologies
Materials that can be precisely designed at the nanoscale could allow 'supercapacitors' to store more energy while maintaining their fast charge time. Researchers from the Huazhong University of Science and Technology, Imperial College London and the Massachusetts Institute of Technology performed simulations and experiments that show special electrode materials could be precisely engineered to produce supercapacitors that charge quickly and store more energy.

Early humans optimised stone tool use at Tanzania’s Olduvai Gorge
Early Stone Age populations living up to 1.8 million years ago made complex decisions in selecting different types of stone to optimise a variety of cutting tools, according to a new study by UCL, University of Kent and the Centre for Human and Social Sciences, Spain. The study, published in the Journal of Royal Society Interface , offers new insight into the complexity of stone tool use, design and production.

New archaeological discoveries reveal birch bark tar was used in medieval England
Scientists from the University of Bristol and the British Museum, in collaboration with Oxford Archaeology East and Canterbury Archaeological Trust, have, for the first time, identified the use of birch bark tar in medieval England - the use of which was previously thought to be limited to prehistory.

Stretchy and squeezy soft sensors one step closer thanks to new bonding method
Stretchy and squeezy soft sensors one step closer thanks to new bonding method
Imperial College London bioengineers have found a way to create stretchy and squeezy soft sensing devices by bonding rubber to electrical components. Stretchy and squeezy soft sensors that can fit around body parts or squeezed in hands could be used for applications including sports and rehabilitation after injury or stroke.

What protects killer immune cells from harming themselves?
White blood cells, which release a toxic potion of proteins to kill cancerous and virus-infected cells, are protected from any harm by the physical properties of their cell envelopes, find scientists from UCL and the Peter MacCallum Cancer Centre in Melbourne. Until now, it has been a mystery to scientists how these white blood cells - called cytotoxic lymphocytes - avoid being killed by their own actions and the discovery could help explain why some tumours are more resistant than others to recently developed cancer immunotherapies.

UK needs to act to prevent electric vehicle battery waste mountain - new study
Recycling technologies for end-of-life lithium ion batteries (LIBs) are not keeping pace with the rapid rise of electric vehicles, storing up a potentially huge waste management problem for the future, according to a new study. A review of lithium ion battery recycling led by the University of Birmingham suggests that, while electric vehicles (EVs) offer a solution for cutting pollution, governments and industry need to act now to develop a robust recycling infrastructure to meet future recycling need.

Scientists spy unstable semiconductors
Scientists from Cardiff University have, for the first time, spotted previously unseen “instabilities” on the surface of a common compound semiconductor material. The findings could potentially have profound consequences for the development of future materials in the electronic devices that power our daily lives.

Physicists shed new light on how liquids behave with other materials
Using a range of theoretical and simulation approaches, physicists from the University of Bristol have shown that liquids in contact with substrates can exhibit a finite number of classes of behaviour and identify the important new ones. Their findings, published in the Proceedings of the National Academy of Sciences (PNAS) , challenge the accepted wisdom on wetting and drying phase behaviour.

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.
