Recycling CO2 might be possible in the future

While the question of CO2-emissions becomes increasingly worrying for most members of society, the answer from many government officials sounds dim. As of now, the reduction of pollution with the greenhouse gas is only dealt with through advocacy of lower consumption: we institute daylight saving times, No Car days or ban plastic bags. Whether or not we agree with these measures, they are undoubtedly inconvenient.

Metal on semiconductors may lead to invisibility cloaks

Researchers have developed a new technique that peppers metallic nanoparticles into semiconductors, an advance that could boost the efficiency of LED lighting by 50 percent and even pave the way for invisibility cloaking devices.

It’s the first technique that can inexpensively grow metal nanoparticles both on and below the surface of semiconductors.

The process adds virtually no cost during manufacturing and its improved efficiency could allow manufacturers to use fewer semiconductors in finished products, making them less expensive.
