A team has succeeded in developing world’s first stretchable aqueous Li-ion batteries that may power the next generation of wearable devices. A recent study, affiliated with UNIST has presented a bioinspired Jabuticaba-like hybrid carbon/polymer (HCP) composite that was developed into a stretchable current collector using a simple and cost-effective solution process. Using the HCP composite as a stretchable current collector, the research team has, for the first time, developed a highly stretchable rechargeable lithium-ion battery (ARLB) based on aqueous electrolytes.

Stretchable electronic devices have recently attracted tremendous attention as next-generation devices due to their immense flexibility...

Scientists at the National Center for Supercomputing Applications (NCSA), at the University of Illinois at Urbana-Champaign, have pioneered the use of GPU-accelerated deep learning for rapid detection and characterization of gravitational waves. This new approach will enable astronomers to study gravitational waves using minimal computational resources, reducing time to discovery and increasing the scientific reach of gravitational wave astrophysics. This innovative research was recently published in Physics Letters B.

A new battery technology, based on a metal-mesh membrane and electrodes made of molten sodium and nickel chloride, could open the way for more intermittent, renewable power sources on the grid. It could make wind and solar capable of delivering reliable baseload electricity...

“Imagine if someone were to fine-tune our system so that you could get 85 percent of the carbon and nitrogen back from waste into protein without having to use hydroponics or artificial light,” said House. “That would be a fantastic development for deep-space travel.” Image: Space Toilet © iStock Photo ALJ1

A Penn State team has shown that it is possible to rapidly break down solid and liquid waste to grow food with a series of microbial reactors, while simultaneously minimizing pathogen growth. “We envisioned and tested the concept of simultaneously treating astronauts’ waste with microbes while producing a biomass that is edible either directly or indirectly depending on safety concerns,” said Christopher House, professor of geosciences, Penn State...
