Jan 24, 2024 (Nanowerk News) As we transition to a new era in computing, there is a need for new devices that integrate electronic and photonic functionalities at the nanoscale while enhancing the interaction between photons and electrons. In an important step toward fulfilling this need, researchers have developed a...
Atmospheric pressure changes could be driving Mars’ elusive methane pulses
Jan 24, 2024 (Nanowerk News) New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars’ atmosphere; knowing when and where to look for methane can help the Curiosity rover search for signs of life. “Understanding Mars’ methane variations...
Vibrating nanobubbles could lead to better water treatment
Jan 24, 2024 (Nanowerk News) Fresh research into the physics of vibrating nanobubbles reveals that they do not heat up as much as previously thought (Nano Letters, "Thermal Oscillations of Nanobubbles"). Vibrating nanobubbles have surprising uses as ultrasound contrast agents in cancer diagnosis. They can also be forced to collapse...
Researchers add a ‘twist’ to classical material design
Jan 24, 2024 (Nanowerk News) Researchers with the Department of Energy’s SLAC National Accelerator Laboratory, Stanford University and the DOE's Lawrence Berkeley National Laboratory (LBNL) grew a twisted multilayer crystal structure for the first time and measured the structure’s key properties. The twisted structure could help researchers develop next-generation materials...
