Oct 29, 2024 (Nanowerk News) In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold with near-infrared light (NIR), the bacteria...
New metal 3D printing technology for ultra-strong materials used in space
Oct 29, 2024 (Nanowerk News) The research team led by Dr. Jeong Min Park from the Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), in collaboration with Professor Jung Gi Kim of Gyeongsang National University and Professor Hyoung Seop Kim of Pohang University of Science and...
Surprise at the grain boundary
Oct 29, 2024 (Nanowerk News) Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for a surprise: “Iron atoms not only segregate to the interface, but they form entirely unexpected cage-like structures,” explains...
New solvent free 3D printing material could enable biodegradable implants
Oct 29, 2024 (Nanowerk News) Additive manufacturing (AM) has revolutionized many industries and holds the promise to affect many more in the not too distant future. While people are most familiar with the 3D printers that function much like inkjet printers, another type of AM offers advantages using a different...
A new chemistry for CRISPR
Oct 28, 2024 (Nanowerk News) CRISPR-Cas9 has long been likened to a kind of genetic scissors, thanks to its ability to snip out any desired section of DNA with elegant precision. But it turns out that CRISPR systems have more than one strategy in their toolkit. A mechanism originally discovered...
Seeing a black hole’s jet in a new light
Oct 28, 2024 (Nanowerk News) Research led by the University of Michigan has pored over more than two decades’ worth of data from NASA’s Chandra X-Ray Observatory to show there’s new knotty science to discover around black holes. In particular, the study looks at the high-energy jet of particles being...
Astronomers discover one of the fastest-spinning stars in the Universe
Oct 28, 2024 (Nanowerk News) The Milky Way still holds many secrets about the universe. Now, researchers from DTU have managed to uncover one of them using an X-ray space telescope mounted on the International Space Station (ISS). It is a small but extremely massive and fast-spinning object - a...
More efficient data retrieval from synthetic molecular polymer data storage
Oct 28, 2024 (Nanowerk News) Increasing amounts of data require storage, often for long periods. Synthetic polymers are an alternative to conventional storage media because they maintain stored information while using less space and energy. However, data retrieval by mass spectrometry limits the length and thus the storage capacity of...
What if you eat nanoplastics?
Oct 28, 2024 (Nanowerk News) In a laboratory set-up simulating the human stomach and intestine, researchers at the University of Amsterdam have explored the fate of plastic nanoparticles during gastrointestinal digestion. In a paper in Chemosphere ("What if you eat nanoplastics? Simulating nanoplastics fate during gastrointestinal digestion"), they report how...
Nanoscale layer boosts signal strength in fluorescence and Raman spectroscopy
Oct 28, 2024 (Nanowerk News) While we might picture a biologist as a researcher hunched over a light microscope, carefully scrutinizing a single bacterium, modern scientists have more powerful instruments at their disposal to investigate, at much smaller scales, the internal structures of living cells. Fluorescence and Raman spectroscopy have...
