Functionalized Å-scale Pores in Graphene for Carbon Capture

Kuang-Jung Hsu

Single-layer graphene, hosting a high density of functionalized molecular-sieving atom-thick pores, is considered to be an excellent material for gas separation membranes. These functionalized atom-thick pores enable the shortest transport pathway across t ...

Two-dimensional atomically bridged nanoporous silicate-based membranes for gas separation

Mostapha Dakhchoune

The synthesis of molecular-sieving two-dimensional zeolitic membranes by the assembly of crystalline building blocks without resorting to the secondary growth process is highly desirable. The precise pore size for molecular sieving, ultrathin thickness, an ...

Etching nanopores in single-layer graphene with a sub-angstrom resolution in molecular sieving

Shiqi Huang

Single-layer graphene (SLG) membranes, hosting molecular-sieving nanopores have been regarded as the ultimate gas separation membranes, attributing to the fact that they are the thinnest possible molecular barrier. However, the expected attractive performa ...

Metal Soap Membranes for Gas Separation

Kumar Varoon Agrawal, Jian Hao, Davide Campi, Deepu Joseph Babu, Qi Liu

Metal soaps or metal alkanoates are metal-organic complexes held together with metal cations and the functional groups of hydrocarbon chains. They can be synthesized at a high yield by simply mixing the metal and organic sources, forming crystalline framew ...

Modified surface

Michael Graetzel, Shaik Mohammed Zakeeruddin, Péter Kalman Péchy

The present invention relates to modified surfaces. The surfaces comprise an inorganic material on which a phosphinic acid derivative is adsorbed. The phosphinic acid thus turns out to be a new anchoring group useful for surface derivatisation. The inventi ...

Separation properties of supported ionic liquid-polydimethylsiloxane membrane in pervaporation process

Zhaofu Fei

Pervaporation separation properties of water-butan-l-of binary mixtures were measured with the use of three supported liquid membranes at 37 C, namely PDMS, 1-ethenyl-3-ethyl-imidazolium hexafluorophosphate-PDMS, and tetrapropyl-ammonium tetracyanoborate-P ...
