Electrochemical separation and compression of hydrogen
Hydrogen gas is used widely in industry, including in metal annealing, float-glass production and silicon wafer manufacturing, among others, but greater than 80% of the H2 used for these processes is typically vented or flared as waste. A new electrochemical…
Nitrogen fixation under ambient conditions
The transition-metal-catalyzed reduction of nitrogen is an alternative to the traditional energy-intensive Haber-Bosch process for producing ammonia. In these reaction systems, metallocenes or potassium graphite are typically used as the reducing reagent, and conjugate acids of pyridines or related compounds…
High-strength Al alloy for 3-D printing is moving into commercial production
The first high-strength, wrought-aluminum alloy powder designed for use in additive manufacturing (3-D printing) applications is moving into commercial production. The powder was developed by HRL Laboratories (Malibu, Calif.; www.hrl.com) for use in laser powder-bed fusion 3-D printers. The company…
Disinfecting water with photocatalytic nanosheets
Scientists at the Chinese Academy of Sciences (Beijing; www.cas.cn) and Yangzhou University (Jiangsu, China; www.yzu.edu.cn) have developed a technique for disinfecting water by using graphitic carbon nitride sheets. They claim their technique purifies water in 30 minutes, killing more than…
