Aug 02, 2022 (Nanowerk News) Scientists and engineers are constantly developing new materials with unique properties that can be used for 3D printing, but figuring out how to print with these materials can be a complex, costly conundrum. Often, an expert operator must use manual trial-and-error — possibly making thousands...
Webb captures stellar gymnastics in the Cartwheel Galaxy
Aug 02, 2022 (Nanowerk News) NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation and the galaxy’s central black hole. Webb’s powerful infrared gaze produced this detailed image of the Cartwheel and two smaller companion galaxies against a backdrop...
A new step towards using magnetic bacteria in cancer treatment
Aug 02, 2022 (Nanowerk News) Imagine a tiny vehicle, a nanocar (one million times smaller than a millimetre), equipped with a magnetic structure that allows it to be controlled and steered by means of magnetic fields. Let's imagine that we can insert this car into the human body and send...
New nanoparticle-based material could help detect antibiotics in water
Aug 02, 2022 (Nanowerk News) An international team of researchers has developed a new type of strong and elastic two-dimensional (2D) membrane (Small, "Strong and Elastic Membranes via Hydrogen Bonding Directed Self-Assembly of Atomically Precise Nanoclusters"). The invention could prove useful, for instance, in detecting remnants of antibiotics from water....
A nanofluidic osmotic energy generator
Aug 02, 2022 (Nanowerk Spotlight) In estuaries, where rivers flow into the sea, enormous free-energy dissipation takes place when fresh river water mixes with salty sea water. The release of Gibbs free energy from mixing seawater and fresh water is estimated to be up to 0.8 kW per cubic meter....
A flexible device that harvests thermal energy to power wearable electronics
Aug 02, 2022 (Nanowerk News) Wearable electronics, from health and fitness trackers to virtual reality headsets, are part of our everyday lives. But finding ways to continuously power these devices is a challenge. University of Washington researchers have developed an innovative solution: the first-of-its kind flexible, wearable thermoelectric device that...
Comparison of two nano rulers
Aug 01, 2022 (Nanowerk News) Researchers from PD Dr. Gregor Hagelueken's group at the Institute of Structural Biology of the UKB used PELDOR spectroscopy to study the movement of substrate-binding proteins (Nature Communications, "Cross-validation of distance measurements in proteins by PELDOR/DEER and single-molecule FRET"). These proteins grab their substrate and...
Turning fish waste into quality carbon nanomaterials
Aug 01, 2022 (Nanowerk News) Thanks to their low toxicity, chemical stability, and remarkable electrical and optical properties, carbon-based nanomaterials are finding more and more applications across electronics, energy conversion and storage, catalysis, and biomedicine. Carbon nano-onions (CNOs) are certainly no exception. First reported in 1980, CNOs are nanostructures composed...
