Abstract: A method for the formation of flexible surface enhanced Raman spectroscopy substrates with filtering capabilities. The method produces thin flexible substrates that have a nanoparticle ink deposited thereon. The nanoparticle ink may be any suitable nanoparticle ink which includes stabilized nanoparticles such as silver, gold or copper nanoparticles. The substrates and nanoparticle ink undergo a thermal treatment for an amount of time sufficient to remove liquid vehicle and a substantial portion of the stabilizer. The thermal treatment provides a fractal aggregate nanoparticle layer on the substrate suitable for Raman spectroscopy. Such flexible SERS substrates may be used to detect trace amounts of analyte in large volume samples.

Abstract: A treatment system for treating water, such as produced water that is produced during hydraulic fracturing. The system employs a combination of a plasma spark discharge and an RF oscillating electric field. The plasma spark discharge and the RF oscillating electric field may be employed simultaneously or in an overlapping manner within a chamber to treat the water. The treatment system is able to kill microorganisms as well as reduce or eliminate fouling due to, for example, bicarbonates. In some embodiments, grids are employed to further enhance the heat produced by the RF oscillating electric field.

Abstract: The invention is directed to apparatus for treating water by exposing the water to a pulsed plasma discharge. The pulsed plasma discharge is generated using a suitable electrode configuration to generate the plasma discharge in the fluid. Apparatus useful in the method may include a vessel, at least two electrodes for generating a plasma discharge in water, and a flow inlet and a flow outlet to allow water to be passed through the vessel. Also described is an in-line water treatment, where a pulsed plasma discharge is used in a pipe carrying moving water. Plasma based fluid treatment system may have many advantages in comparison to other treatment methods, such as very minimal maintenance, low operating power, and minimal pressure loss through the device.

Ecological Momentary Assessment (EMA) may be used for automated and/or manual acquisition of data related to triggers associated with BED. Risk factors may be captured in real-time to provide data to both patients and clinicians. For manual data acquisition, the user may be prompted to input emotional states, urges to binge, eating behavior, and binge episodes. For automated acquisition, time, place (e.g. via GPS), medicine adherence, and physical activity may be recorded. The user may be provided with alerts and/or interventions when it is determined that they are at risk of binging.
Abstract: A sample material is scanned with a transmission electron microscope (TEM) over multiple steps having a predetermined size at a predetermined angle. Each scan at a predetermined step and angle is compared to a template, wherein the template is generated from parameters of the material and the scanning. The data is then analyzed using local mis-orientation mapping and/or Nye's tensor analysis to provide information about local strain states.
Abstract: Disclosed is a device and method for contacting a biological substrate. A non-thermal plasma device delivers a non-thermal plasma discharge using a dielectric conduit, an igniter electrode and a RF electrode. The dielectric conduit fluidicly communicates a gas therethrough and an igniter electrode ionizes at least a portion of the gas. The RF electrode, disposed circumferentially proximate to the exterior of the dielectric conduit, generates non-thermal plasma from the ionized gas. The non-thermal plasma is discharged from the dielectric conduit and contacts a biological substrate. The non-thermal plasma discharge may be suitable for tissue bonding and sterilization applications.

Abstract: Full-AC load flow constitutes a core computation in power system analysis. A performance gain with a hardware implementation of a sparse-linear solver using a Field Programmable Gate Array (FPGA) is achieved by use of a DC network emulation of the power system bus. Analog Behavioral Models (ABMs)are used in an efficient strategy for designing analog emulation engines for large-scale power system computation. A generator model is also developed using analog circuits for load flow emulation for power system analysis to reduce computation time. The generator model includes reconfigurable parameters using operational transconductance amplifiers (OTAs). The circuit module is used with other reconfigurable circuits, i.e., transmission lines and loads.
