Four new "hot Jupiter" extrasolar planets have been detected as part of the Hungarian-made Automated Telescope Network-South (HATSouth) exoplanet survey. The newly found alien worlds are generally similar in size, but vary ...
Designing wearable sensors or other devices demands robust, flexible electronics. Extremely thin films, just one atom thick, such as molybdenum disulfide (MoS2), hold promise. Large-area synthesis of these materials is required ...
