US Patent:

20110014100, Jan 20, 2011

Filed:

Nov 24, 2009

Appl. No.:

12/624726

Inventors:

Jason E. Bara - Denver CO, US
Dean E. Camper - Superior CO, US
Christopher J. Gabriel - Boulder CO, US

International Classification:

B01D 53/62
C01B 31/20

US Classification:

423229, 423228, 4234371

Abstract:

A process to capture and sequester an impurity gas from a fluid stream. The impurity gas capture is accomplished by contacting the fluid stream with an impurity removing mixture, the mixture comprising an ionic liquid and an amine compound under conditions sufficient to reduce the amount of impurity gas from said fluid stream. The captured impurity gas is sequestered by reacting the impurity gas with a sequestration material.

International Classification:

C02F 1/44

US Classification:

210650, 427244, 210489

Abstract:

The invention provides membranes useful for filtration of water and other liquids. The membrane may be a composite membrane having a polymer layer incorporating quaternary phosphonium or ammonium groups. The polymer layer may be resistant to protein adsorption in an aqueous environment. The membrane may also be a surface-modified membrane in which a polymer having quaternary phosphonium or ammonium groups is covalently attached to the membrane surface. Methods for making and using the membranes of the invention are also provided.

International Classification:

C09K 19/34
C07D 285/12
C07D 271/107
C07D 417/04

Abstract:

New classes of thiadiazole and oxadiazole compounds for use in LC mixtures are disclosed. In an embodiment, the new classes of thiadiazoles and oxadiazoles comprise at least one phenyl ring attached to the heterocyclic ring, where no alkyl, alkenyl or alkynyl tails are attached to the phenyl ring, but one alkyl, alkenyl or alkynyl tail is attached to the other end of the molecule, and a fluoro or cyano group appears in the para position of the phenyl ring. These compounds are disclosed as being effective at inducing smectic A phases in liquid crystal mixtures, particularly in liquid crystal mixtures also possessing a smectic C phase, more particularly in materials possessing a chiral smectic C (ferroelectric) phase.
