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...

A study that outlined the advance, along with the construction and demonstration of an assortment of tiny robots that walk,...
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...
Achieving sub-MHz optical features resonator-free in solid-state
Jun 17, 2022 (Nanowerk Spotlight) Ultra-narrow optical features with a spectral bandwidth below 1 megahertz are highly sought-after for applications in ultrahigh-precision sensing, narrow-band filtering, and information storage for optical computing – but unfortunately they are extremely challenging to generate. Conventionally, high-Q resonators that have a minimum loss in optical...
New method helps exfoliate hexagonal boron nitride nanosheets
Jun 16, 2022 (Nanowerk News) Researchers recently reported an innovative mechanical process for controllably exfoliating hexagonal boron nitride nanosheets (h-BNNSs). This method, known as the "water-icing triggered exfoliation process," was proposed by Prof. ZHANG Junyan's group from the Lanzhou Institute of Chemical Physics (LICP) of the Chinese Academy of Sciences...
