Novel ultrafast electron microscopy technique advances understanding of processes applicable to brain-like computing
Aug 05, 2024 (Nanowerk News) Today’s supercomputers consume vast amounts of energy, equivalent to the power usage of thousands of homes. In response, researchers are developing a more energy-efficient form of next-generation supercomputing that leverages artificial neural networks. These networks mimic the processes of neurons, the basic unit in the...
Using small black holes to detect big black holes
Aug 05, 2024 (Nanowerk News) The origin of supermassive black holes found at the centers of galaxies, is still one of the biggest mysteries in astronomy. They may have always been massive and formed when the Universe was still very young. Alternatively, they may have grown over time by accreting...
Self-powered pump harnesses light and chemistry to target, capture pollutants
Aug 05, 2024 (Nanowerk News) Dartmouth researchers have developed a self-powered pump that uses natural light and chemistry to target and remove specific water pollutants, according to a new report in the journal Science ("A molecular anion pump"). As water enters the pump, a wavelength of light activates a synthetic...
Toward a quantum electron microscope
Aug 05, 2024 (Nanowerk News) Electron microscopes have long been indispensable tools in scientific research, offering unparalleled resolution and magnification capabilities. However, current electron microscopy technologies face significant limitations, including high cost, large size, strong radiation damage to samples through interaction with the electron beam, and the need for cryogenic...
45 Percent transparency achieved in microdisplays
Aug 05, 2024 (Nanowerk News) Transparent electronics are already providing reliable services in some applications. For instance, they can be found as ultra-thin layers for touch displays or as transparent films with printed antennas for mobile communications. However, OLED microdisplays have not been transparent so far. As part of the...
