Perovskite solar cells: Defects trap charge carriers - and release them again

“An international team at HZB and Charles University Prague has investigated how charge carriers in so called MAPI-perovskite semiconductors interact with different defects. They show that a large proportion of defects quickly releases trapped charge carriers. These results could …

Quantum Phase Transition Detected on a Global Scale Deep Inside the Earth

“Spin transition discovered in the Earth’s mantle; finding will improve understanding the Earth’s interior, and enable better understanding of tectonic events including volcanic eruptions and earthquakes. The interior of the Earth is a mystery, especially at greater depths …

Raspberry Pi 400 as a USB HID Keyboard

“Hook your Pi 400 up to your PC somehow, using a USB Type-C cable into the power port. Anker make good ones- I used a 3m white one for my tests.”

Research Team Unlocks Secret Path to a Quantum Future

“Berkeley Lab-led research key to next-gen quantum computing and technologies In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins …

Resurrecting quasicrystals: Findings make an exotic material commercially viable

“Self-healing phenomenon could reduce defects that rendered quasicrystals impractical A class of materials that once looked as if it might revolutionize everything from solar cells to frying pans—but fell out of favor in the early 2000s—could be poised …

Rotary Dial Arduino Input

“This project was intended to serve as a proof of concept for using a rotary phones dial as an interface between a user and the Arduino microcontroller. However, this experiment quickly turned into an opportunity to learn all about the …
