| Breakthrough in light sources for new quantum technology Posted: 29 Aug 2014 05:42 AM PDT One of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons (electronic circuits). First, it is necessary to create a stream of single photons and control their direction. Researchers have now succeeded in creating a steady stream of photons emitted one at a time and in a particular direction. |
| A new, tunable device for spintronics Posted: 28 Aug 2014 10:53 AM PDT An international team of scientists has developed a tunable spin-charge converter made of GaAs. Spin-charge converters are important devices in spintronics, an electronic which is not only based on the charge of electrons but also on their spin and the spin-related magnetism. Spin-charge converters enable the transformation of electric into magnetic signals and vice versa. |
| Avatars make the Internet sign to deaf people Posted: 28 Aug 2014 06:12 AM PDT It is challenging for deaf people to learn a sound-based language, since they are physically not able to hear those sounds. Hence, most of them struggle with written language as well as with text reading and comprehension. Therefore, most website content remains inaccessible for them. Computer scientists want to change the situation by means of a method they developed: animated online characters display content in sign language. In the long term, deaf people would be able to use the technique to communicate on online platforms via sign language. |
