Patent number: 8106430Abstract: The invented ink-jet printing method for the construction of thin film transistors using all SWNTs on flexible plastic films is a new process. This method is more practical than all of existing printing methods in the construction TFT and RFID tags because SWNTs have superior properties of both electrical and mechanical over organic conducting oligomers and polymers which are often used for TFT. Furthermore, this method can be applied on thin films such as paper and plastic films while silicon based techniques cannot be used on such flexible films. These are superior to the traditional conducting polymers used in printable devices since they need no dopant and they are more stable. They could be used in conjunction with conducting polymers, or as stand-alone inks.Type: GrantFiled: September 14, 2010Date of Patent: January 31, 2012Assignee: William Marsh Rice UniversityInventors: Gyou-Jin Cho, Min Hun Jung, Jared L.

Patent number: 8089628Abstract: The present invention provides a technology called Pulse-Multiline Excitation or PME. This technology provides a novel approach to fluorescence detection with application for high-throughput identification of informative SNPs, which could lead to more accurate diagnosis of inherited disease, better prognosis of risk susceptibilities, or identification of sporadic mutations. The PME technology has two main advantages that significantly increase fluorescence sensitivity: (1) optimal excitation of all fluorophores in the genomic assay and (2) “color-blind” detection, which collects considerably more light than standard wavelength resolved detection. Successful implementation of the PME technology will have broad application for routine usage in clinical diagnostics, forensics, and general sequencing methodologies and will have the capability, flexibility, and portability of targeted sequence variation assays for a large majority of the population.Type: GrantFiled: February 18, 2009Date of Patent: January 3, 2012Assignees: Baylor College of Medicine, Rice UniversityInventors: Graham B.

Patent number: 8084243Abstract: We have shown that the control of solventogenesis and sporulation can be genetically uncoupled in C. acetobutylicum. In strain 824(pASspo), the absence of SpoIIE causes sporulation to be blocked at stage II. The cell remains in a vegetative state, and this allows solvent production to proceed for longer and for solvents to accumulate more rapidly and to a higher concentration. The characteristic drop in OD600 observed in wild type and control strains of C. acetobutylicum after 48-72 hours as the cells transition from the solventogenic phase to sporulation is notably absent in the fermentations of 824(pASspo). Mutant S (wild type background, spoIIE disrupted), Mutant BS (Mutant B background, spoIIE disrupted), Mutant HS (Mutant H background, spoIIE disrupted) and Mutant bukS (buk- background, spoIIE disrupted) were generated to create stable solvent producing bacteria with complete inactivation of the SpoIIE protein. Similarity between the SpoIIE protein of C. acetobutylicum, B.Type: GrantFiled: August 21, 2008Date of Patent: December 27, 2011Assignee: William Marsh Rice UniversityInventors: George N.
