A Method for Characterizing Adeno-Associated Virus Capsids with Thermal Unfolding and Mass Spectrometry

This invention describes modulating the temperature of the solution in an electrospray needle prior to charge-detection mass spectrometry (CD/MS) to enable discrimination between the individual stabilities of multiple forms of viral particles that may be present in an AAV preparation. This increased discrimination provides the operator with a unique...

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...

Surface-Modified Electrospray Needles for Mass Spectrometry

With this invention, electrospray needles used in mass spectrometry are coated to prevent sticking and clogging of analytes, resulting in improved mass detection sensitivity and consistency of analysis. The coating comprises an organic material covalently bonded to an interior surface of the electrospray needle. The coating is electrically non-conductive...

Deconvolution of Charge Detection-Mass Spectrometry Data

This mass spectrometry analysis software and method extends the UniDec Bayesian deconvolution algorithm for application to two-dimensional charge detection-mass data. A 2D plot of m/z versus charge is created from raw data. Smoothing and background subtraction may be used, and deconvolution is applied to remove uncertainty in the charge and the m/z...

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...
