Astronomers discover metal-rich galaxy in early universe
Feb 27, 2023 (Nanowerk News) Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge. Their initial focus, and the infrared observatory’s target, was SPT0418-47, one of the brightest...
Scientists observe transition to chaotic behavior on the nanometer scale
Feb 27, 2023 (Nanowerk News) Chaotic behavior is typically known from large systems: for example, from weather, from asteroids in space that are simultaneously attracted by several large celestial bodies, or from swinging pendulums that are coupled together. On the atomic scale, however, one does normally not encounter chaos –...
Capturing nanoplastics in tap water with light
Feb 27, 2023 (Nanowerk News) Nanoplastics are plastics that have been discarded from our daily lives and that enter ecosystems in the size scale below 1 micro-metter after their physical and chemical disintegration. Recent research has shown that the concentration of microplastics in the major rivers in South Korea is...
Producing extreme ultraviolet laser pulses efficiently through wakesurfing behind electron beams
Feb 27, 2023 (Nanowerk News) A laser pulse surfing in the wake of an electron beam pulse could get upshifted from visible to extreme ultraviolet light, simulations done at the University of Michigan have shown. The approach could enable more efficient generation of high-energy laser light, perhaps even to X-rays....
New microfluidics technology to improve cancer detection and treatment
Feb 27, 2023 (Nanowerk News) Researchers from the University of Technology Sydney have developed a new device that can detect and analyse cancer cells from blood samples, enabling doctors to avoid invasive biopsy surgeries, and to monitor treatment progress. Cancer is a leading cause of illness and death in Australia,...
World’s fastest laser camera films combustion in real time
Feb 27, 2023 (Nanowerk News) By illuminating a sample surface with short laser beam pulses, it is possible to film sequences of various chemical and physical reactions. A research team that included researchers from the University of Gothenburg has now developed the world’s fastest single-shot laser camera, which is at...
