Zeolite Ddr Membranes

View page
US Patent:
20130064747, Mar 14, 2013
Filed:
Sep 12, 2012
Appl. No.:
13/611988
Inventors:
Zhengzhi Zhou - Atlanta GA, US
Sankar Nair - Atlanta GA, US
Assignee:
Georgia Tech Research Corporation - Atlanta GA
International Classification:
B01J 29/04
B01D 53/00
US Classification:
423230, 502 4, 502 62, 502 60, 502 64, 502 73, 502 74, 423210
Abstract:
DDR nanocrystals of uniform size and structure were synthesized using hydrothermal secondary growth and then used to make DDR zeolite membranes and for any other use where uniform, small DDR zeolite crystals are beneficial.

US Patent:
20120247336, Oct 4, 2012
Filed:
Feb 14, 2012
Appl. No.:
13/396411
Inventors:
Zhengzhi ZHOU - Atlanta GA, US
Sankar NAIR - Atlanta GA, US
Assignee:
GEORGIA TECH RESEARCH CORPORATION - Atlanta GA
International Classification:
B01D 71/02
B32B 5/16
C01B 39/00
US Classification:
96 4, 423706, 428402
Abstract:
DDR nanocrystals were synthesized using hydrothermal secondary growth. The morphology of the nanoparticles can be manipulated by changing the ratio of silica to water, the synthesis temperature, and the mineralizing agents. Specifically, nanocrystals with morphology of hexagonal plates, octahedral, and diamond-like plates are disclosed. These nanoparticles can be used as seed coatings for DDR membrane growth on substrates, and for the fabrication of mixed matrix membranes, and for any other use where uniform, small DDR zeolite crystals are beneficial.

US Patent:
20140273692, Sep 18, 2014
Filed:
Mar 14, 2013
Appl. No.:
13/828471
Inventors:
- Duluth GA, US
Zhengzhi Zhou - Suwanee GA, US
Assignee:
NCR CORPORATION - Duluth GA
International Classification:
C09J 133/10
C09J 7/02
US Classification:
442151, 524507, 428355 AC, 428354, 428344
Abstract:
High tack repositionable adhesive obtained by combining an acrylic copolymer permanent pressure sensitive adhesive with a hydrophobically modified ethoxylate urethane (HEUR) thickener. The adhesive provides repositionable substrates, such as thermal paper, with high tack. Methods for preparing the high tack repositionable adhesive are provided.
