Record ammonia production achieved with inexpensive cobalt catalyst at low temperatures
Tokyo Institute of Technology

Ammonia (NH3) is one of the most widely produced chemicals in the world, with a production of over 187 million tons in 2020. About 85% of it is used to produce nitrogenous fertilizers, while the rest is used for refining petroleum, manufacturing a wide range of other chemicals, and creating synthetic fibers such as nylon.

Treating Polluted Water with Nanofiber Membranes
American Institute of Physics (AIP)

In Biointerphases, researchers develop a fabrication method to increase the efficacy and longevity of membrane separation technology. The team created a nanofibrous membrane with electrospinning, in which a liquid polymer droplet is electrified and stretched to make fibers, and increased the roughness of the membrane surface by loading it with silver nanoparticles. In water, this rough surface promotes a stable layer of water, which acts as a barrier to prevent oil droplets from entering the membrane. The technology is greater than 99% effective at separating a petroleum ether-in-water emulsion.

Scientists created a nanoscale pattern of holes on a thin film of metal oxide known as titania to control the material’s electronic properties. The thin film noticeably improved the flow of electrons and inhibited the flow of ions in the material, increasing the material’s electrical conductivity. This will aid in next-generation microelectronics applications and quantum information processing.
