Celestial bauble intrigues astronomers

(PhysOrg.com) -- With the holiday season in full swing, a new image from an assembly of telescopes has revealed an unusual cosmic ornament. Data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton have been combined ...

How long do electrons live in graphene?

Together with international colleagues, scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have added another important component towards understanding the material graphene; a material that is currently receiving ...

Dutch team provides alternative to optical semiconductor amplifiers

Researchers at the University of Twente's MESA+ research institute have developed a material capable of optical amplifications that are comparable to those achieved by the best, currently available semiconductor optical amplifiers. ...

Using nanophotonics to reshape on-chip computer data transmission

A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data ...

Using photons to manage data

Managing light to carry computer data, such as text, audio and video, is possible today with laser light beams that are guided along a fibre-optic cable. These waves consist of countless billions of photons, which carry information ...

Chemically assembled metamaterials may lead to superlenses

(PhysOrg.com) -- Nanomanufacturing technology has enabled scientists to create metamaterials -- stuff that never existed in nature -- with unusual optical properties. They could lead to "superlenses" able to image proteins, ...
