Sep 22, 2022 (Nanowerk News) Engineered living materials promise to aid efforts in human health, energy and environmental remediation. Now they can be built big and customized with less effort. Bioscientists and synthetic biologists at Rice University have introduced centimeter-scale, slime-like colonies of engineered bacteria that self-assemble from the bottom...
Researchers uncover how to 3D-print one of the strongest stainless steels
Sep 22, 2022 (Nanowerk News) For airliners, cargo ships, nuclear power plants and other critical technologies, strength and durability are essential. This is why many contain a remarkably strong and corrosion-resistant alloy called 17-4 precipitation hardening (PH) stainless steel. Now, for the first time ever, 17-4 PH steel can be...
Tiny swimming robots treat deadly pneumonia in mice
Sep 22, 2022 (Nanowerk News) Nanoengineers at the University of California San Diego have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs...
Fundamental research improves understanding of new optical materials
Sep 21, 2022 (Nanowerk News) Research into the synthesis of new materials could lead to more sustainable and environmentally friendly items such as solar panels and light emitting diodes (LEDs). Scientists from Ames National Laboratory and Iowa State University developed a colloidal synthesis method for alkaline earth chalcogenides. This method...
Researchers show that chiral oxide catalysts align electron spin
Sep 21, 2022 (Nanowerk News) Controlling the spin of electrons opens up future scenarios for applications in spin-based electronics (spintronics), for example in data processing. It also presents new opportunities for controlling the selectivity and efficiency of chemical reactions. Researchers recently presented first successes with the example of water splitting...
New Webb image captures clearest view of Neptune’s rings in decades
Sep 21, 2022 (Nanowerk News) NASA's James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet's rings in more than 30 years, but its cameras reveal the ice giant in a...
Could a magnetar and a Be-Star be the source of Fast Radio Bursts?
Sep 21, 2022 (Nanowerk News) Observations of nearly 2,000 bursts from a fast radio burst called FRB 20201124A and the presentation of a model to explain the observed characteristics are reported in Nature and Nature Communications papers. The findings suggest that this fast radio burst may originate from a complex...
