  Houston TX (SPX) Jan 29, 2019 When you light up a metal nanoparticle, you get light back. It's often a different color. That's a fact - but the why is up for debate. In a new paper in the American Chemical Society journal Nano Letters, Rice chemist Stephan Link and graduate student Yi-Yu Cai make a case that photoluminescence, rather than Raman scattering, gives gold nanoparticles their remarkable light-emitting properties. The researchers say understanding how and why nanoparticles emit light is important for improving ... read more |

Platinum, a noble metal, is oxidised more quickly than expected under conditions that are technologically relevant. This has emerged from a study jointly conducted by the DESY NanoLab and the University of Vienna.
Devices that contain platinum, such as the catalytic converters used to reduce exhaust emissions in cars, can suffer a loss in efficacy as a result of this reaction. The team aro ... more |

 Hannover, Germany (SPX) Dec 17, 2018 
The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects.
These cause a background noise which overlaps with gravitational-wave signals. This noise is always presen ... more |

Black holes consume everything that falls within their reach, yet astronomers have spotted jets of particles fleeing from black holes at nearly the speed of light. New computer simulations have revealed what gives these particles such speed: cosmic robbery.
The particle escapees steal some of the spinning black hole's rotational energy, accomplishing this through two main mechanisms involv ... more |
