New route to carbon-neutral fuels from carbon dioxide
A new way to convert carbon dioxide into the building block for sustainable liquid fuels was very efficient in tests and did not have the reaction that destroys the conventional device.

Chemists uncover a mechanism behind doping organic semiconductors
Semiconductors — and our mastery of them — have enabled us to develop the technology that underpins our modern society. These devices are responsible for a wide range of electronics, including circuit boards, computer chips and sensors.
Read moreWelcome indoors, solar cells
Scientists have developed organic solar cells optimized to convert ambient indoor light to electricity. The power they produce is low, but is probably enough to feed the millions of products that the internet of things will bring online.
Read moreThe magic wavelength of cadmium
Researchers experimentally determined a property of cadmium called the magic wavelength which is considered essential for the development of the most accurate clocks ever envisaged. The researchers hope this may permit simple and robust atomic clocks so accurate they could be used to improve our understanding of current theories and even test for new physics.

Acoustics is a missing dimension in silicon chips because acoustics can complete specific tasks that are difficult to do with electronics and optics alone. For the first time researchers have added this dimension to the standard silicon photonics platform. The concept combines the communication and bandwidth offered by light with the selective processing of sound waves.
