From Yellowcake to Nuclear Reactor Fuel

Uranium mining methods produce a liquid with uranium dissolved in it. This is filtered and the uranium is then separated by ion exchange, precipitated from the solution, filtered, and dried to produce a bright yellow uranium oxide concentrate known as ‘yellowcake,’ which contains 0.7% U235.

Physicist builds tractor beam inspired by Star Trek

To celebrate the 50th anniversary of the original Star Trek series premiere, physics professor (and sci-fi fan) David Grier offers a look into his New York University lab—the birthplace of the real-life tractor beam.

Understanding semiconductor stability aids next generation materials development

While metal oxide semiconductors have been widely considered to exhibit outstanding durability, performance degradation in these solar energy harvesting components happens frequently. Understanding the degradation is essential for developing stable, efficient photosystems. To address the failure, a team at the Joint Center for Artificial Photosynthesis, Calif., uncovered the mysteries of photochemical instability in a widely […]
