Jul 22, 2022 (Nanowerk News) Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases – including so-called per- or polyfluorinated hydrocarbons, or PFCs – have a significant share in this development. Researchers at the Institute of Organic Chemistry of Heidelberg University...
Measuring the universe with star-shattering explosions
Jul 22, 2022 (Nanowerk News) An international team of 23 researchers led by Maria Dainotti, Assistant Professor at the National Astronomical Observatory of Japan (NAOJ), has analyzed archive data for powerful cosmic explosions from the deaths of stars and found a new way to measure distances in the distant Universe...
How to tell if artificial intelligence is working the way we want it to
Jul 22, 2022 (Nanowerk News) About a decade ago, deep-learning models started achieving superhuman results on all sorts of tasks, from beating world-champion board game players to outperforming doctors at diagnosing breast cancer. These powerful deep-learning models are usually based on artificial neural networks, which were first proposed in the...
Making implants safer with a nanoparticle-modified biomedical implant material
Jul 22, 2022 (Nanowerk News) An interdisciplinary team of researchers at the University of Alabama at Birmingham have developed a new plasma-enabled process that could limit the proliferation of toxins from implants into a patient’s bloodstream. The team, led by Vinoy Thomas, Ph.D., associate professor in the UAB School of...
Metallacycles embrace carbon nanotubes
Jul 22, 2022 (Nanowerk News) Chemical modification of single-walled carbon nanotubes is a critical step to exploit their properties. Either the covalent modification or the supramolecular functionalization of their surface has resulted in nanotube products with application in, for example, optical sensing and electronics. Other modifications, such as the mechanical...
First-of-its-kind sprayable multiscale coating to shield surfaces from viruses, bacteria
Jul 22, 2022 (Nanowerk News) A first-of-its-kind sprayable coating that can prevent the surface spread of infection from bacteria and viruses - including COVID-19 - over a sustained period –– has been developed by a team of Australian researchers. Described in the journal Advanced Science ("Shielding Surfaces from Viruses and...
The best semiconductor of them all?
Jul 21, 2022 (Nanowerk News) Silicon is one of the most abundant elements on Earth, and in its pure form the material has become the foundation of much of modern technology, from solar cells to computer chips. But silicon’s properties as a semiconductor are far from ideal. For one thing,...
How different cancer cells respond to drug-delivering nanoparticles
Jul 21, 2022 (Nanowerk News) Using nanoparticles to deliver cancer drugs offers a way to hit tumors with large doses of drugs while avoiding the harmful side effects that often come with chemotherapy. However, so far, only a handful of nanoparticle-based cancer drugs have been FDA-approved. A new study from...
Self-assembling 2D materials at a liquid-liquid interface
Jul 21, 2022 (Nanowerk News) Molecular 2D materials find immense applications in materials science, owing to their wide structural variety and easy controllability. Establishing a simple and efficient method for their synthesis is, therefore, important. Now, scientists from Japan present a simple method for synthesizing heterolayer coordination nanosheets, a promising...
