Getting two for one: 'Bonus' electrons in germanium nanocrystals can lead to better solar cells

Researchers from FOM, the University of Amsterdam, the Delft University of Technology and the University of the Algarve have discovered that when light hits germanium nanocrystals, the crystals produce 'bonus electrons'.

Google's patent is for odor-removing wearable

A Google patent for a wearable aims to make you smell better when you need to smell better. The patent was issued this month by the U.S. Patent and Trademark Office. Google was granted a patent for an "odor removing device" also referred to as a "fragrance emission device" that carries an activity sensor, a communication portion, and a route-suggesting portion. The device can perform a number of functions. It can tell if you have body odor and it can deodorize the odor too; it can steer you away of friends who may be in locations where they would bump into you—and your bad odor. The device would map out an alternative route on your phone so that you can avoid them while you are smelling so bad. The patent talks about an activity module which can detect when the user starts to exert himself or herself. The module may pick up a rise in sweat levels, increase in body odor or body temperature, or any other parameter that may indicate exertion.
