This MOF selectively captures radioactive iodine

A challenge in recovering fissile material from spent nuclear fuel is separating radioactive components that cannot be reused as fuel. Researchers at Sandia National Laboratory (Albuquerque, N.M.; www.sandia.gov) have fabricated metal-organic frameworks (MOFs) capable of selectively capturing gaseous iodine from…

Nano-engineered glass absorbs organic contaminants and serves as a nanoreactor

An organosilica material with unique structural properties due to its nanoscale architecture has been used to extract hydrocarbons and other organic contaminants from water. Marketed as Osorb by ABS Materials Inc. (Wooster, Ohio; www.absmaterials.com), the nanostructured glass represents a platform…

Heavy-metal removal process joins advantages of two existing technologies

A newly demonstrated system for removing trace levels of heavy metals from water combines the positive traits of two existing technologies — chemical precipitation and electrowinning — while avoiding drawbacks of each. An engineering team at Brown University (Providence, R.I.;…
