Gel-like coating can boost lithium-sulfur battery performance

Scientists have developed an ultra-thin gel-like coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries.

“Our approach is general, in that it can be integrated with virtually any kind of sulfur electrode to increase cycling stability,” said lead investigator of the study Hailiang Wang, Assistant Professor of Chemistry at Yale University in New Haven, Connecticut, US.

In a study published online in the Proceedings of the National Academy of Sciences, the researchers described the new material which can be applied to any sulfur cathode.

A cathode is the positive terminal on a battery.

Sulfur cathodes coated with the material can be stably discharged and recharged for more than 1,000 cycles, enhancing the battery’s efficiency and number of cycles, according to the researchers.

“The developed film is so thin and light it will not affect the overall size or weight of the battery, and thus it will function without compromising the energy and power density of the device,” Wang said. Continue reading Gel-like coating can boost lithium-sulfur battery performance

Facial recognition tech helps diagnose rare genetic disease

Researchers have successfully used a facial recognition software to diagnose a rare, genetic disease that mainly affects children of African, Asian and Latin American descent, paving the way for physicians to diagnose the disease by snapping a photo.

The technology used to diagnose the disease, 22q11.2 deletion syndrome, also known as DiGeorge syndrome and velocardiofacial syndrome, is similar to that used in airports and on Facebook. Continue reading Facial recognition tech helps diagnose rare genetic disease

UK workers at risk of being replaced by robots

More than 10 million UK workers are at high risk of being replaced by robots within 15 years as the automation of routine tasks gathers pace in a new machine age, a report said on Friday.

The report by the consultancy firm PwC found that 30 per cent of jobs in Britain were potentially under threat from breakthroughs in artificial intelligence (AI). Continue reading UK workers at risk of being replaced by robots

‘Sensory skin’ to detect damage outside spacecraft

Scientists at NASA’s Kennedy Space Center in Florida are developing a system that acts like a sensory skin to help astronauts to know exactly when the outside of their spacecraft has been damaged

The “Flexible Damage Detection System” technology may offer a possible solution to NASA’s problem of figuring out in real-time where a spacecraft is damaged and how seriously. Continue reading ‘Sensory skin’ to detect damage outside spacecraft
