Summary of "Synthesis of nano zinc-based metal-organic frameworks under ultrasound irradiation in comparison with solvent-assisted linker exchange: Increased storage of N and CO."

Isostructural nano Zn(II)-based metal-organic frameworks (MOFs), Zn-TMU, has been synthesized by ultrasound process and solvent-assisted linker exchange (SALE). Zn(II)-MOFs were investigated as CO capture compounds. Compared with ultrasound process, the as-prepared daughter frameworks showed enhanced CO sorption capacity, ascribed to the existence of structural defects during the SALE method. This study demonstrated that the gas storage depends mainly on the quality and defects in the structure, which depends on the synthetic conditions. This study is a new report of increasing CO sorption in Zn-TMU by a SALE method.

Medical and Biotech [MESH] Definitions

Supramolecular networks that consist of ordered arrangements of organic electron donor linkers (usually ditopic or polytopic organic carboxylates) and metal cations. They can have an extremely high surface area and adjustable pore size that allows for the insertion of other molecules capable of various functions such as catalysis, capture of carbon dioxide, and drug delivery.

Proteases which use a metal, normally ZINC, in the catalytic mechanism. This group of enzymes is inactivated by metal CHELATORS.

ENDOPEPTIDASES which use a metal such as ZINC in the catalytic mechanism.

EXOPEPTIDASES which use a metal such as ZINC in the catalytic mechanism.

Organic polymeric materials which can be broken down by naturally occurring processes. This includes plastics created from bio-based or petrochemical-based materials.
