Jun 17, 2022 (Nanowerk News) A scientist from the Faculty of Pure and Applied Sciences at the University of Tsukuba developed a method for producing electrically conductive polymers that assume a helical configuration. By using a liquid crystal as a template, he was able to produce optically active polymers that...
Dying stars could seed interstellar medium with carbon nanotubes
Jun 17, 2022 (Nanowerk News) In the mid-1980s, the discovery of complex carbon molecules drifting through the interstellar medium garnered significant attention, with possibly the most famous examples being Buckminsterfullerene, or "buckyballs" – spheres consisting of 60 or 70 carbon atoms. However, scientists have struggled to understand how these molecules...
Microrobot device removes brain hemorrhages due to strokes or aneurysms
Jun 17, 2022 (Nanowerk News) A new treatment for strokes caused by bleeding in the brain that uses a magnetically controlled microrobot-enabled self-clearing catheter has been shown to be 86% effective in animal models, according to a paper published in Nature Communications ("Application of magnetically actuated self-clearing catheter for rapid...
Electrons take the fast and slow lanes
Jun 17, 2022 (Nanowerk News) Imagine a road with two lanes in each direction. One lane is for slow cars, and the other is for fast ones. For electrons moving along a quantum wire, researchers in Cambridge and Frankfurt have discovered that there are also two ‘lanes’, but electrons can...

End-of-life plan needed for tens of thousands of wind turbine blades
Jun 17, 2022 (Nanowerk News) A new study led by The University of South Australia indicates tens of thousands of wind turbine blades will end up in landfill by the end of the decade unless end-of-life programs are established soon. The study (Renewable and Sustainable Energy Reviews, "End-of-life policy considerations...
New spectroscopic insights into hydrogen bonds
Jun 17, 2022 (Nanowerk News) Hydrogen bonds are of fundamental interest in materials science, physics and chemistry. An international team including scientists from the University of Bayreuth has now achieved surprising insights into the formation of hydrogen bonds using a novel method that enables the application of NMR spectroscopy in...
New pentacene derivative has 100 times more light durability
Jun 17, 2022 (Nanowerk News) A research group led by Professor Yoshio Teki of the Osaka Metropolitan University Graduate School of Engineering has succeeded in developing a new pentacene derivative that is more than 100 times more photostable than TIPS-pentacene, a photostable pentacene derivative. Additionally, the team has further clarified...
Disinfectant mechanism of nano-sized electrostatic atomized water particles on SARS-CoV-2
Jun 17, 2022 (Nanowerk News) Current disinfection strategies have major drawbacks, which is why the World Health Organization does not advise routine spraying or fogging of biocidal agents, or UV light sterilization, in occupied areas. One possible alternative is nano-sized electrostatic atomized water particles generated by an electrospray device developed...
Mysterious ‘blue blobs’ reveal a new kind of star system
Jun 17, 2022 (Nanowerk News) University of Arizona astronomers have identified five examples of a new class of stellar system. They're not quite galaxies and only exist in isolation. The new stellar systems contain only young, blue stars, which are distributed in an irregular pattern and seem to exist in...
