Vortices in superconductors play an important role in operating limits and applications of the superconductors. Scanning Hall probe microscopes have proven themselves to be quantitative and non-invasive tools for investigating magnetic samples down to 50 nm scale. Penetration of vortices in high quality single crystal Bi2Sr2CaCu1O8+delta superconductor has been studied in real-time with single vortex resolution at 77 K using a low temperature scanning Hall probe microscope (LT-SHPM). Vortices have been observed to be annihilated by the antivortices in small M-H loops.

Ultra-fast charge exchange spectroscopy for turbulent ion temperature fluctuation measurements on the DIII-D tokamak (invited)
Uzun Kaymak, İlker Ümit; McKee, G. R. (2012-10-01)
A novel two-channel, high throughput, high efficiency spectrometer system has been developed to measure impurity ion temperature and toroidal velocity fluctuations associated with long-wavelength turbulence and other plasma instabilities. The spectrometer observes the emission of the n = 8-7 hydrogenic transition of C+5 ions (lambda(air) = 529.06 nm) resulting from charge exchange reactions between deuterium heating beams and intrinsic carbon. Novel features include a large, prism-coupled high-dispersion, v...
Near-field radiative transfer in spectrally tunable double-layer phonon-polaritonic metamaterials
Didari, Azadeh; Elçioğlu, Elif Begüm; Okutucu Özyurt, Hanife Tuba; Mengüç, M. Pinar (Elsevier BV, 2018-6)
Understanding of near-field radiative transfer is crucial for many advanced applications such as nanoscale energy harvesting, nano-manufacturing, thermal imaging, and radiative cooling. Near-field radiative transfer has been shown to be dependent on the material and morphological characteristics of systems, the gap distances between structures, and their temperatures. Surface interactions of phononic materials in close proximity of each other has led to promising results for novel near-field radiative trans...
Real-time benchtop NMR spectroscopy for the online monitoring of sucrose hydrolysis
Soyler, Alper; Bouillaud, Dylan; Farjon, Jonathan; Giraudeau, Patrick; Öztop, Halil Mecit (Elsevier BV, 2020-01-01)
The online monitoring of chemical reactions by using benchtop Nuclear Magnetic Resonance (NMR) spectroscopy has become increasingly attractive for the past few years. The use of quantitative online NMR spectroscopy is a promising alternative to traditional analytical methods with its rapid, quantitative and non-invasive nature that makes it applicable to complex and diverse biochemical mixtures like food systems. In this study, sucrose hydrolysis by invertase was chosen as a model reaction for online monito...
Investigation of Self-Excited Ultrahigh Speed Induction Generators for Distributed Generation Systems
Jardan, Rafael K.; Varga, Zoltan; Nagy, Istvan (2011-09-10)
Application of ultra high speed induction generators (IG) in a system developed for utilization of renewable and waste energies that can be applied in Distributed Generation System is presented. The energy conversion is made by a turbine-generator set. For the electromechanical energy conversion application of special high speed induction generators has been studied and described in the paper. The design and analysis of the system are relied on computer simulation techniques verified by test results.
Frequency Modulated Raman Spectroscopy

The coupling of plasmonic and mechanical properties at the nanoscale is of great potential for the development of next generation devices capable to detect weak forces, mass changes, minute displacements and temperature induced effects. Both the transduction of mechanical motion to the scattered light fields in term of polarization or intensity modulation and plasmon-driven mechanical oscillations have already been demonstrated. Quasi static tunable hot spots have recently been designed and applied to surfa...
