Jun 29, 2022 (Nanowerk News) A Northwestern University-led team of astrophysicists has developed the first-ever full 3D simulation of an entire evolution of a jet formed by a collapsing star, or a “collapsar.” Because these jets generate gamma ray bursts (GRBs) — the most energetic and luminous events in the...
New single-mode semiconductor laser delivers power with scalability
Jun 29, 2022 (Nanowerk News) Berkeley engineers have created a new type of semiconductor laser that accomplishes an elusive goal in the field of optics: the ability to maintain a single mode of emitted light while maintaining the ability to scale up in size and power. It is an achievement...
Review article on metal-organic framework (MOF) nanosheets assembled on the surface of water
Jun 29, 2022 (Nanowerk News) Rie Makiura, Associate Professor at the Graduate School of Engineering, Osaka Metropolitan University has published a review article on the simple synthesis of nanosheet materials endowed with high-precision nanoscale pores. Nanosheets are two-dimensional materials with nanometer-scale thickness (10-6 mm), attracting attention as ultra-thin functional units...
Detecting fluorescence signals from nanoscale thin films
Jun 29, 2022 (Nanowerk News) The Jena-based industrial research institution INNOVENT e.V. has incorporated fluorescent nanoparticles into thin-film technologies. These particles can now be detected thanks to a special measurement method developed at the Ferdinand-Braun-Institut (FBH) in Berlin. Till date, this was not possible because the fluorescent materials provide very...
The puzzling link between star formation and radio emission in galaxies
Jun 29, 2022 (Nanowerk News) To understand the formation and evolution of galaxies like our Milky Way, it is of particular importance to know the amount of newly formed stars in both nearby and distant galaxies. For this purpose, astronomers often use a link between the infrared and radio radiation...
Assigning moving features in high-speed atomic force microscopy
Jun 29, 2022 (Nanowerk News) In video microscopy techniques, a practical issue is how to properly assign moving features. Indeed, any video recording setup has a finite frame rate, and if several identical (or similar) moving features appear in the frame, it is not trivial to understand which feature went...
New method based on smart materials for experimenting with cells
Jun 28, 2022 (Nanowerk News) Scientists from 4D-BIOMAP, an ERC research project at the Universidad Carlos III de Madrid (UC3M), have developed a new experimental method, based on magneto-active polymers, to study cellular behaviour. These compounds, which consist of a polymeric matrix (e.g., an elastomer) containing magnetic particles (e.g., iron),...
Electrospinning promises major improvements in wearable technology
Jun 28, 2022 (Nanowerk News) Wearable technology has exploded in recent years. Spurred by advances in flexible sensors, transistors, energy storage, and harvesting devices, wearables encompass miniaturized electronic devices worn directly on the human skin for sensing a range of biophysical and biochemical signals or, as with smart watches, for...
New ‘plug-and-play’ biobatteries use bacterial interactions to generate power for weeks
Jun 28, 2022 (Nanowerk News) Researchers at Binghamton University, State University of New York have developed a “plug-and-play” biobattery that lasts for weeks at a time and can be stacked to improve output voltage and current. As our tech needs grow and the Internet of Things increasingly connects our devices...
A sanitizer in the galactic center region
Jun 28, 2022 (Nanowerk News) An international group of researchers led by Arnaud Belloche (MPIfR, Bonn, Germany) reports the first identification iso-propanol in interstellar space, a substance which is used as a sanitizer on Earth. Iso-propanol is the largest alcohol detected so far, demonstrating the increasing complexity of members of...
