New plastic biomaterials could lead to tougher, more versatile medical implants
A new thermoplastic biomaterial, which is tough and strong but also easy to process and shape has been developed by researchers at the University of Birmingham. A type of nylon, the material's shape memory properties enable it to be stretched and moulded but able to reform into its original shape when heated.

Virus DNA spread across hospital ward in 10 hours
Virus DNA left on a hospital bed rail was found in nearly half of all sites sampled across a ward within 10 hours and persisted for at least five days, according to a new study by UCL and Great Ormond Street Hospital (GOSH). The study, published as a letter in the Journal of Hospital Infection , aimed to safely simulate how SARS-CoV-2, the virus that causes Covid-19, may spread across surfaces in a hospital.

New materials could make greener fast-charging batteries
Researchers have created a fast-charging battery prototype that uses sodium instead of lithium, potentially leading to more sustainable batteries. The prototype is one of the first to successfully use sodium in an organic battery that can be quickly charged and discharged hundreds of times without losing any capacity.

Working up a sweat could power future wearable devices
A new generation of wearable devices could be powered by human sweat instead of conventional, environmentally-unfriendly batteries, scientists say. In a new paper published today in the journal Advanced Materials, engineers from the Bendable Electronics and Sensing Technologies (BEST) group at the University of Glasgow describe how working up a sweat could be enough to generate power for exercise monitors and other electronic devices in the future.

New material engineered to capture carbon dioxide emissions
Researchers at UCL and Newcastle University have developed a new class of self-forming membrane to separate carbon dioxide from a mixture of gases. Operating like a coffee filter, it lets harmless gases, such as nitrogen, exit into the atmosphere and allows the carbon dioxide to be processed separately.

Largest amount of microplastics found on ocean floor
Our researchers have helped record the highest level of microplastics ever found on the ocean floor - with up to 1.9 million pieces in an area of just one square metre. The discovery highlights the problem of plastic pollution in our seas, 99 per cent of which lies beneath the waves. Working as part of an international team the researchers have shown how deep-sea currents act as conveyor belts, transporting tiny plastic fragments and fibres across the seafloor.

MRI scanning assists with next generation battery design
Magnetic resonance imaging (MRI) can provide an effective way of supporting the development of the next generation of high-performance rechargeable batteries, according to research led by the University of Birmingham. The technique, which was developed to detect the movement and deposition of sodium metal ions within a sodium battery, will enable faster evaluation of new battery materials, and help to accelerate this type of battery's route to market.

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.

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.
