Orthogonal sequencing multiplexer for superconducting nanowire single-photon detectors with RSFQ electronics readout circuit
Superconducting nanowire single-photon detectors (SNSPD) offer a high sensitivity up to the single-photon level over a wide spectral range with high counting rate and high detection efficiency. Innovative...
PublicationsSpectroscopic detection and quantification of heme and heme degradation products
Heme and heme degradation products play critical roles in numerous biological phenomena which until now are only partially understood. One reason for that are the very low concentrations at which free...
PublicationsMagnetic heating effect of nanoparticles with different sizes and size distributions
We present a comparative study of dynamic and quasistatic magnetic properties of iron oxide nanoparticles. The heating effect in an ac field in the range 0-30 kA/m at 210 kHz was measured calorimetrically....
PublicationsDegradation in molybdenum thin films and Mo/AuPd bilayers and its reduction by sidewall passivation
Molybdenum is a common material for superconducting thin films used for example in transition edge sensors as Mo/metal bilayer. For such applications long term stability of the superconducting parameters...
PublicationsSimultaneous Measurement of Partial Pressure of O2 and CO2 with a Hybrid Interferometer
In this work, a hybrid interferometer for simultaneous measurement of the partial pressures of O2 and CO2 mixtures is reported. The sensing head consists in the combination of two interferometric structures,...
PublicationsElectron backscatter diffraction on femtosecond laser sulfur hyperdoped silicon
This paper analyzes the impact of femtosecond laser pulse irradiation on the crystallinity of silicon wafers by means of electron backscatter diffraction (EBSD) measurements. EBSD based orientation imaging...
PublicationsIn Vivo Characterization of Atherosclerotic Plaque Depositions by Raman-Probe Spectroscopy and in Vitro Coherent Anti-Stokes Raman Scattering Microscopic Imaging on a Rabbit Model
Visualization as well as characterization of inner arterial plaque depositions is of vital diagnostic interest, especially for the early recognition of vulnerable plaques. Established clinical techniques...
PublicationsInterpreting CARS images of tissue within the C-H-stretching region
Single band coherent anti-Stokes Raman scattering (CARS) microscopy is the fastest implementation of nonlinear vibrational imaging allowing for video-rate image acquisition of tissue. This is due to the...
PublicationsRaman Spectroscopy as a Potential Tool for Detection of Brucella spp. in Milk
Detection of Brucella, causing brucellosis, is very challenging, since the applied techniques are mostly time-demanding and not standardized. While the common detection system relies on the cultivation...
PublicationsStructural alterations in rat liver proteins due to STZ-induced diabetes and the recovery effect of selenium: An FTIR microspectroscopy and neural network study
The relation between protein structural alterations and tissue dysfunction is a major concern as protein fibrillation and/or aggregation due to structural alterations has been reported in many disease...
