How to shift gears in a molecular motor
Jan 29, 2024 (Nanowerk News) Scientists have long strived to develop artificial molecular motors that can convert energy into directed motion. Researchers at Linköping University in Sweden have now presented a solution to a challenging problem: how motion can be transferred in a controlled manner from one place to another...
Utilising active microparticles for artificial intelligence
Jan 29, 2024 (Nanowerk News) Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists at Leipzig University have now created a type of neural network that works not with electricity but with so-called active colloidal particles. In their publication in the journal Nature Communications...
Lopsided galaxies shed light on the speed of dark matter
Jan 29, 2024 (Nanowerk News) So how can the speed of dark matter be measured? The prerequisite is to find a galaxy in the universe that moves relative to dark matter. Since everything in the universe is in motion and there is a great deal of dark matter, it is...
Sound-powered sensors stand to save millions of batteries
Jan 29, 2024 (Nanowerk News) Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually comes from batteries, which are replaced as soon as they are empty. This...
Astronomers spot 18 black holes gobbling up nearby stars
Jan 29, 2024 (Nanowerk News) Star-shredding black holes are everywhere in the sky if you just know how to look for them. That’s one message from a new study by MIT scientists, appearing in the Astrophysical Journal ("A New Population of Mid-Infrared-Selected Tidal Disruption Events: Implications for Tidal Disruption Event...
Researchers developed a new self-assembly method to fabricate multilayered 2D nanosheets
Jan 29, 2024 (Nanowerk News) As electronic devices get smaller, the materials needed to create them get smaller as well. Nanoscience is the study of extremely small materials that find uses in energy storage, electronics, health and safety applications and more. Now a team led by the U.S. Department of...
New biocompatible nanotweezers enhance control over diverse nanoparticles with versatility and precision
Jan 29, 2024 (Nanowerk Spotlight) The precise manipulation of individual nanoparticles has long enticed researchers across disciplines like materials science, nanotechnology and biomedicine. But physics itself has imposed key barriers—namely the diffraction limit constraining conventional optical traps alongside insufficient laser intensities to induce stable trapping. This has left nanoscale tweezing...
How does a ‘reverse sprinkler’ work? Researchers solve decades-old physics puzzle
Jan 29, 2024 (Nanowerk News) For decades scientists have been trying to solve Feynman’s Sprinkler Problem: How does a sprinkler running in reverse – in which the water flows into the device rather than out of it – work? Through a series of experiments, a team of mathematicians has figured...
Setting a new standard of precision in making quantum computer chips
Jan 29, 2024 (Nanowerk News) A team of University of New South Wales (UNSW) quantum computing engineers, in close collaboration with colleagues at the University of Melbourne, has broken a new record in precision manufacturing, in the quest to fabricate the silicon chips of future quantum computers. In a paper...
