Theoretical physicists manipulate light with nanoscale objects

For years, scientists have long wrestled with the control and manipulation of light, a long-standing scientific ambition with major implications for the development of technology. With the growth in nanophotonics, scientists ...

Serious shortcomings in aging tests of new solar cell materials

Researchers at Aalto University have found that only a fraction of stability tests done on new types of solar cells meet proper requirements. Tests lack common standards and should have been done in real-world conditions ...
