Filed:

Oct 30, 2000

Appl. No.:

09/702029

Inventors:

Leonard Katz - Oakland CA
Lu Liu - Redwood City CA
Loleta M. Chung - San Francisco CA

Assignee:

Kosan Bioscience, Inc. - Hayward CA

International Classification:

C12N 120

US Classification:

43525235

Abstract:

Recombinant host cells that produce rapamycin analogues are constructed by deleting or modifying rapamycin biosynthetic gene cluster genes and are useful in the production of compounds used as antifungals, anticancers, immunosuppressants, and neurotrophins.

Appl. No.:

11/070392

Assignee:

University of Washington - Seattle WA

International Classification:

G02F 1/15

US Classification:

359265, 359273, 359267

Abstract:

Syntheses of a new blue EC monomer (ProDOT-MePro), and a new red EC monomer (ProDOP-Et2) are described. Two additional new types of EC monomers based on 3,4-alkylenedioxythiophene include fluorinated EC monomers and an EC monomer including silicon. EC polymer devices having more than one different color EC polymer to enable additional colors to be provided using subtractive color mixing are also described, as well as EC polymer devices incorporating a logo, image, or text, are generally obscured when the device is colored, but become visible when the device is not colored. Also described are EC polymer devices that include a cathodic EC polymer layer, a gel electrolyte, a counter electrode, and a reference electrode. Working prototypes of such devices exhibit significant increases in the speed of transition of the EC device from a colored state to a transparent state.

International Classification:

G02F 1/15

US Classification:

359265

Abstract:

Three green EC materials based on thiophene, and a green EC material based on pyrazine are disclosed. A first thiophene derivative (2,3-Di-thiophen-2-yl-thieno[3,4-b]pyrazine), which was previously investigated as a nonlinear optical material, is here disclosed for its use as an EC material, and for its incorporation into an EC device. Synthesis of two new thiophene derivatives (2,5-di(thien-2-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene and 2,5-(2,3-dihydro-thieno[3,4-b][1,4]dioxin-5-yl)-3,4-di(2,2,2-trifluoro-ethoxy)-thiophene), and a new pyrazine derivative (2,3-dibenzyl-5,7-di(thien-2-yl)thieno[3,4-b]pyrazine) are also disclosed, since these materials are all able to selectively change to a green color state, and can be polymerized to achieve a green EC polymer.

International Classification:

G02F 1/15

US Classification:

359265, 359240, 359245

Abstract:

Electropolymerization of EC monomers is employed to obtain an EC polymer film deposited on a substrate. A first embodiment of a method to produce the film employs cyclic voltammetry alone, while a second embodiment deposits a very thin homogeneous layer using chronoamperometry, and then cyclic voltammetry is employed to increase the density of the film. Another aspect of the present invention is directed to specific web like configurations for a grid of conductive material deposited onto a transparent substrate. The web like configuration is based either on concentric circles, or on concentric ellipses. Yet another aspect of the present invention is directed to an imaging system including a digital window that is disposed between a prism and a patterned analytic layer.
