Abstract:
The present invention provides titanium dioxide/single-walled carbon nanotube composites (TiO/SWCNTs), articles of manufacture, and methods of making and using such composites. In certain embodiments, the present invention provides membrane filters and ceramic articles that are coated with TiO/SWCNT composite material. In other embodiments, the present invention provides methods of using TiO/SWCNT composite material to purify a sample, such as a water or air sample.
Rotating Reverse Osmosis Filtration
US Patent:
2003014, Aug 7, 2003
Filed:
Feb 1, 2002
Appl. No.:
10/060393
Inventors:
Richard Lueptow - Evanston IL, US
International Classification:
B01D061/02
US Classification:
210/652000, 210/107000, 210/321650, 210/321680, 210/637000
Abstract:
Reverse osmosis filtration is conducted using a rotatable inner body having an axis of rotation and a reverse osmosis filter member disposed on the inner body. An outer body is disposed about the inner body and spaced therefrom to provide an annulus between an annular outer surface of the filter member and an annular inner surface of the outer body to receive a liquid to be filtered. A source of the liquid under pressure is communicated to an inlet to the annulus. The inner body is rotated at a rotational speed effective to generate Taylor or other vortices in the liquid in the annulus.
Acoustic Natural Gas Fuel Sensor
US Patent:
5537854, Jul 23, 1996
Filed:
May 24, 1993
Appl. No.:

Richard M. Lueptow - Evanston IL
International Classification:
G01N 2902
US Classification:
73 2401
Abstract:
A gaseous fuel analyzer having a flow through chamber equipped with sound producing means at one end and sound receiving means at the other for measuring an acoustic property of fuel flowing through the chamber and for numerically relating the acoustic property to the combustion character of the fuel.
