In normal differentiated cells, most of the genome is densely methylated, except CpG islands near promoters of actively transcribed genes. Maintaining this boundary between unmethylated promoter-associated and adjacent methylated regions is crucial as loss of segregation can lead to disease. Unfortunately, it is not clear where these boundaries are,...

Improved performance of epoxies

Unmet Need: Use of renewable and nontoxic feedstock for epoxiesCurrently over 90% of commercial epoxy resins are derived from the non-renewable petrochemical bisphenol A (BPA). However, BPA is considered as a suspicious endocrine disrupting chemical and may cause harm to human health. In the recent decade, a variety of biobased epoxies have been developed...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids

The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

JobViz: User Interface for Visualization of Majors & Jobs

Invention Summary: University (and industry) career search portals and web-based job search engines allow users to search on many items (e.g., education, location, level, etc.) and then present a text based list of potential job opportunities. University career portals are not as conductive to exploration by job and career searchers as they could...

Methods for chemical degradation of epoxies using organic salts as catalysts

Unmet Need: Environmental friendly and cost-effective degradation of epoxiesRecycling of thermosetting polymers is both economically and environmentally important due to the prevalence of polymers in landfills. Strong alkali or acid have been used for this purpose. Harsh chemicals would result in environmental pollution as well as it would turn the...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers

Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

All-Fiber Multicore Fiber Laser Devices

Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
