Sep 06, 2022 (Nanowerk News) Through giant lobes of gamma radiation, an international team of researchers have found a small satellite galaxy of the Milky Way filled with dark matter, but whose emissions are more likely the result of millisecond pulsars blasting out cosmic particles, reports a new study in...
Martian rock-metal composite shows potential of 3D printing on Mars
Sep 06, 2022 (Nanowerk News) A little Martian dust appears to go a long way. A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket...
Combing light with sharper teeth
Sep 05, 2022 (Nanowerk News) A ruler made of light. That is the simplified comparison that is commonly used to describe what a microcomb is. In short, the principle is based on a laser sending light that circulates inside a small cavity, a so-called micro resonator. There, the light is...
Red Giant Betelgeuse was yellow some 2,000 years ago
Sep 05, 2022 (Nanowerk News) With progressing nuclear fusion in the center of a star, brightness, size, and color also change. Astrophysicists can derive from such properties important information on age and mass of a star. Those stars with significantly more mass than our Sun are blue-white or red –...
Organic thin-film sensors for light-source analysis and anti-counterfeiting applications
Sep 05, 2022 (Nanowerk News) In a recent publication in the scientific journal Advanced Materials ("Accurate Wavelength Tracking by Exciton Spin Mixing"), a team of physicists and chemists from TU Dresden presents an organic thin-film sensor that describes a completely new way of identifying the wavelength of light and achieves...
