Ammonia Synthesis Catalyst: Japan's Air-Stable Electrene Runs at 300°C and 9 Atmospheres

Researchers at the Institute of Science Tokyo have created a surface electrene: a crystal whose outermost layer is a sheet of loose electrons, with a work function lower than cesium. It survives open air because nitrogen caps it, then leaves as ammonia. Here is what it means for green fertilizer, and how it compares with the electrochemical routes pursued in China, Europe and the US.

Hamaoka Nuclear Data Fraud: Chubu Electric Faked Quake Figures, Even During the Probe

Hamaoka nuclear plant sits right atop the Nankai Trough megaquake zone. Its operator, Chubu Electric, shrank the key seismic-safety figure the plant is built against, and kept altering data even after regulators opened a probe, rewriting 69 of 225 datasets. On July 1 the NRA called it fabrication and a cover-up. The real test isn't the reactor's engineering; it's whether Japan's post-Fukushima watchdog has teeth.
