Apr 20, 2022 (Nanowerk News) Georgia State University researchers have successfully designed a new type of artificial vision device that incorporates a novel vertical stacking architecture and allows for greater depth of color recognition and scalability on a micro-level. The new research is published in the journal ACS Nano ("van...
Why Venus rotates, slowly, despite sun’s powerful grip
Apr 20, 2022 (Nanowerk News) If not for the soupy, fast-moving atmosphere on Venus, Earth’s sister planet would likely not rotate. Instead, Venus would be locked in place, always facing the sun the way the same side of the moon always faces Earth. The gravity of a large object in...
Mars may have less water than previously estimated
Apr 20, 2022 (Nanowerk News) Researchers from the Oden Institute and Jackson School of Geosciences have developed an improved model for planet-wide groundwater flow prediction on Mars that is not only more accurate but, according to its author, more elegant too. A graphic rendering of Mars, showing its icy northern...
Lab creates superfluid circuit using fermions to study electron behavior
Apr 20, 2022 (Nanowerk News) Researchers at Dartmouth have built the world’s first superfluid circuit that uses pairs of ultracold electron-like atoms, according to a study published in Physical Review Letters ("Persistent Currents in Rings of Ultracold Fermionic Atoms"). The laboratory test bed gives physicists control over the strength of...
Electronic nanogenerator tattoos as human-machine interfaces
Apr 19, 2022 (Nanowerk News) The field of epidermal electronics, or e-tattoos, covers a wide range of flexible and stretchable monitoring gadgets that are wearable directly on the skin. We have covered this area in multiple Nanowerk Spotlights, for instance stick-on epidermal electronics tattoo to measure UV exposure or tattoo-type...
Extremely sensitive nanosensors can detect trace amounts of molecules
Apr 19, 2022 (Nanowerk News) Utrecht researchers have developed a new type of sensor with an unprecedented ability to detect extremely small amounts of molecules. These sensors can be used to detect and identify trace amounts of substances such as chemical pollutants or molecules important in medicine. The sensors make...
New promising nanogel separates chemicals continuously
Apr 19, 2022 (Nanowerk News) Nanomaterials scientists from Utrecht University have improved a nanogel in such a way that it can now transport individual molecules from one liquid to the other. “By enlarging the surface area between two liquids, we can increase the exchange of chemicals. This technique can make...
New process enables 3D printing of small and complex components made of glass in just a few minutes
Apr 19, 2022 (Nanowerk News) Because of its outstanding transparency as well as its stability in contact with heat or chemicals, glass is relevant for many high-tech applications. However, conventional processes for shaping glass are often tedious, energy-intensive and quickly reach their limits for small and complicated components. The Freiburg...
Jupiter’s moon Io has splendid dunes
Apr 19, 2022 (Nanowerk News) Scientists have long wondered how Jupiter’s innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like “Dune.” Now, a Rutgers research study has provided a new explanation of how dunes can form even on a surface as icy...
New method allows robot vision to identify occluded objects
Apr 19, 2022 (Nanowerk News) Robotic vision has come a long way, reaching a level of sophistication with applications in complex and demanding tasks, such as autonomous driving and object manipulation. However, it still struggles to identify individual objects in cluttered scenes where some objects are partially or completely hidden...
