Jun 29, 2022 (Nanowerk News) Extrusion-based 3D printing/bioprinting is a promising approach to generating patient-specific, tissue-engineered grafts. However, a major challenge in extrusion-based 3D printing and bioprinting is that most currently used materials lack the versatility to be used in a wide range of applications. New nanotechnology has been developed...
First full-scale planetary defense test against potential asteroid impacts on Earth
Jun 29, 2022 (Nanowerk News) NASA’s Double Asteroid Redirection Test (DART) mission is the world’s first full-scale planetary defense test against potential asteroid impacts on Earth. Researchers of the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS now show that instead of leaving behind a...
Falling stardust, wobbly jets explain blinking gamma ray bursts
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...
