Nanjing University Researchers Use Iron to Improve Sodium-Ion Batteries

Researchers at Nanjing University have developed an iron-containing cathode for high-energy sodium-ion batteries. The material uses iron ions to help oxygen reactions reverse more effectively during charging and discharging. Tests improved oxygen-reaction reversibility from 75% to 99%, while a pouch cell reached 206 Wh/kg and retained 87.8% capacity after 100 cycles.

China Starts Construction of Hualong One Nuclear Plant With Cooling Towers

China has started construction of Unit 2 at the Zhaoyuan nuclear power project in Shandong. Developed by CGN, the project will use Hualong One reactors with 203-meter cooling towers. Once all six planned units are operational, the site is expected to produce about 50 billion kilowatt-hours of electricity each year while also supporting nuclear heating and industrial steam applications.

MIT Scientists Show Why a Neutrino Laser Cannot Work

MIT researchers have shown that a proposed neutrino laser is not physically possible under the proposed mechanism. The study found that strong atomic recoil prevents the required quantum amplification, while the fermionic nature of neutrinos creates an opposing quantum effect. The findings challenge an earlier proposal that aimed to produce laser-like neutrino beams using ultracold radioactive atoms.
