Astronomers image for the first time a black hole expelling a powerful jet
Apr 26, 2023 (Nanowerk News) An international team of scientists led by Dr. LU Rusen from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences has used new millimeter-wavelength observations to produce an image that shows, for the first time, both the ring-like accretion structure around a black...
Nanotechnology design opens door to new cancer treatments
Apr 26, 2023 (Nanowerk News) To develop cancer drugs, researchers often have to make tough trade-offs. Most drugs potent enough to kill tumors also cause unpleasant side-effects –and may end up doing more harm than good. Now, researchers and clinicians at Stevens Institute of Technology and Hackensack Meridian Health have...
Nifty nanoparticles help ‘peel back the curtain’ into the world of super small things
Apr 26, 2023 (Nanowerk News) Physicists at The Australian National University (ANU) are using nanoparticles to develop new sources of light that will allow us to “peel back the curtain” into the world of extremely small objects – thousands of times smaller than a human hair – with major gains...
Physicists measure and control electron release from metals in the attosecond range
Apr 26, 2023 (Nanowerk News) By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Rostock and the University of Konstanz have shown that this is the...
Using OLEDs to image magnetic fields
Apr 26, 2023 (Nanowerk News) Smartphones could one day become portable quantum sensors thanks to a new chip-scale approach that uses organic light-emitting diodes (OLEDs) to image magnetic fields. Researchers from the ARC Centre of Excellence in Exciton Science at UNSW Sydney have demonstrated that OLEDs, a type of semiconductor...
