Invisibility cloaks boosts solar energy conversion efficiency

Researchers demonstrated a performance improvement of state-of-the-art silicon solar cells by cloaking their metal contact fingers. The cloaking free-form surfaces are fabricated on silicon heterojunction solar cells using direct laser writing of polymers and subsequent soft imprinting. Cloaking performance is determined experimentally by measuring spatially resolved and angle-resolved current generation and the spectral response of …

Nearing affordable extraction of uranium from seawater, which would unlock over 800 times current reserves and with breeder reactors provide resources for billion years of current world power

The oceans hold more than four billion tons of uranium—enough to meet global energy needs for the next 10,000 years if only we could capture the element from seawater to fuel nuclear power plants. For half a century, researchers worldwide have tried to mine uranium from the oceans with limited success. In the 1990s, Japan …

Antiproton attraction measured to be similar to protons

Researchers revealed evidence this week that the attractive force between antiprotons is similar to that between protons — and measured it. Specifically, the team measured two important parameters: the scattering length and the effective range of interaction between two antiprotons. This gave scientists a fundamental new way to understand the force that holds together the …
