X-ray 'prism' explores chemical changes at the molecular scale

(Phys.org)—Research at SLAC National Accelerator Laboratory demonstrates that ultrashort, ultrabright X-ray laser pulses can reveal details of chemically important molecules at room temperature and in their natural state. ...

Single photon from a quantum emitter? It's a matter of timing...

(Phys.org) —Many systems envisioned for practical quantum information processing require the use of single, indistinguishable photons as carriers of information and logic operators. So researchers in the field need to be ...

Nanocrystal infrared LEDs can be made cheaply

(Phys.org) -- Light-emitting diodes at infrared wavelengths are the magic behind such things as night vision and optical communications, including the streaming data that comes through Netflix. Cornell researchers have advanced ...

Fine-tuning emissions from quantum dots

Tiny particles of matter called quantum dots, which emit light with exceptionally pure and bright colors, have found a prominent role as biological markers. In addition, they are realizing their potential in computer and ...

Creating custom light using 2-D materials

Finding new semiconductor materials that emit light is essential for developing a wide range of electronic devices. But making artificial structures that emit light tailored to our specific needs is an even more attractive ...

Molecular light sources sensitive to environment

A Dutch-French team of scientists led by FOM (Foundation for Fundamental Research on Matter) researcher Dr Danang Birowosuto and University of Twente researcher Dr Allard Mosk has obtained the first experimental evidence ...

Heavy metal frost? A new look at a Venusian mystery

Venus is hiding something beneath its brilliant shroud of clouds: a first order mystery about the planet that researchers may be a little closer to solving because of a new re-analysis of twenty-year-old spacecraft data.
