Jul 12, 2022 (Nanowerk News) A new self-powered, wristwatch-style health monitor invented by researchers at the University of California, Irvine can keep track of a wearerâs pulse and wirelessly communicate with a nearby smartphone or tablet â without needing an external power source or a battery. In a paper published...
Self-driven micropumps propelled by salts show high efficiency in water decontamination
Jul 12, 2022 (Nanowerk News) Chemically propelled micropumps –i.e., small devices capable of driving the flow of a surrounding fluid by generating a chemical gradient and, hence, causing diffusion-osmotic or electroosmotic movements— have attracted great interest for their possible application in water decontamination and environmental remediation, as well as in...

Home > Press > Nano-rust: Smart additive for autonomous temperature control: FAU researchers develop a new, versatile method for temperature monitoring in materialsAbstract:The right temperature matters whether in technical processes, for the quality of food and medicines, or the lifetime of electronic components and batteries. For this purpose, temperature...
Biohybrid material performs like cartilage
Jul 12, 2022 (Nanowerk News) Producing biomaterials that match the performance of cartilage and tendons has been an elusive goal for scientists, but a new material created at Cornell demonstrates a promising new approach to mimicking natural tissue. The results were published in the Proceedings of the National Academy of...
Operating a smart home by breath control
Jul 12, 2022 (Nanowerk News) Researchers at Case Western Reserve University have created a simple prototype device that enables users to control “smart home” technology by changing their breathing patterns. The self-powered unit fits into the nostrils and has the potential to enhance the quality of life for people with...

The ultimate fate of a star shredded by a black hole
Jul 12, 2022 (Nanowerk News) In 2019, astronomers observed the nearest example to date of a star that was shredded, or “spaghettified,” after approaching too close to a massive black hole. That tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took...

In its first published image, Webb telescope delivers deepest infrared image of universe yet
Jul 12, 2022 (Nanowerk News) NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever...
Flashing creates hard-to-get 2D boron nitride
Jul 12, 2022 (Nanowerk News) Rice University scientists who “flash” materials to synthesize substances like graphene have turned their attention to boron nitride, highly valued for its thermal and chemical stability. The process by the Rice lab of chemist James Tour exposes a precursor to rapid heating and cooling to...
