  • Publication number: 20160161414
    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.

  • Publication number: 20160085893
    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.
