New molecular sieves

An international team of researchers recently synthesized polyarylether-based covalent organic frameworks, the most stable crystalline porous material on record. The team, which includes the University of Delaware's Yushan ...

Crystal clear solvent filtration

Covalent organic materials with well-ordered porous microstructures could provide the membranes needed for technology to meet increasingly stringent environmental controls and be cost effective to produce.

Modified enzyme brings value to lignin monomers

The chemical industry faces the challenge of replacing fossil-based building blocks with green alternatives. Biomass is an interesting source of carbon-based molecules. It is also underused because some 25 percent of all ...

New light on making two-dimensional polymers

An international research team with members from Linköping University, the Technical University of Munich and the Deutsches Museum among others, has developed a method to manufacture two-dimensional polymers with the thickness ...

Simultaneous synthesis and fixing of covalent organic frameworks

Covalent organic frameworks (COFs) are versatile materials composed of interconnected organic molecules held together by covalent bonds. These frameworks can be constructed in two-dimensional or three-dimensional (3D) forms ...
