A new heat-resistant membrane

Most polymeric membranes degrade during use, making them impractical for industrial separation processes. To solve this problem, researchers from the State University of New York at Buffalo (SUNY Buffalo; www.buffalo.com), with cooperation for scientists at Rensselar Polytechnic Institute, have created…

Ultrathin films achieve record hydrogen separation

Scientists at École Polytechnique Fédérale de Lausanne (EPFL; Switzerland; www.epfl.ch) have synthesized the first ever metal-organic frameworks (MOFs) membrane with the thickness of just one unit cell. The ultrathin film yields record-high performance for the separation of hydrogen from nitrogen.…

Immobilizing enzymes as a stable, active foam

Researchers at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) have developed a new class of materials — enzyme foams. Normally, foaming modifies the enzyme structure and enzymes lose their biocatalytic activity. The new protein foams, however, are said to…
