Großflächige hochauflösende magnetische Prospektion mit SQUID-Technologie

Remote Excited Raman Optical Activity of Adenine Along Ag Plasmonic Waveguide

We report the remote excited Raman optical activity (ROA) of adenine along Ag plasmonic waveguide. First, the surface plasmons that propagate along Ag nanowire is demonstrated experimentally. Second, the...

Nanostructural inhomogeneities acting as pinning centers in bulk MgB2 with low and enhanced grain connectivity

Regularly distributed structural inhomogeneities in the MgB2 matrix, such as nano-areas with a high concentration of boron (MgBx) and impurity oxygen (Mg–B–O nanolayers or inclusions), are observed...

Acoustic Measurements in a Hexamethyldisiloxane-Loaded Low-Temperature Direct Barrier Discharge (DBD) Plasma Effluent: Nozzle Cleaning

Acoustic emission measurements (AE) as well as laser scattering experiments were performed during SiO2 layer deposition. SiO2 was generated in low temperature atmospheric plasma torches 50 or ≤500 W)...

Self-calibrating lensless inline-holographic microscopy by a sample holder with reference structures

A self-calibration technique for lensless compact chip-microscopes based on inline holography with pinhole illumination is presented. The pinhole illumination wave acts as reference and is needed for the...

Formation and Characterization of Silver Nanoparticles Embedded in Optical Transparent Materials for Plasmonic Sensor Surfaces

Plasmonic nanostructures promise sensing capabilities with the potential for ultrasensitive and robust assays in life sciences and biomedicine. Silver island films represent an interesting and straightforward...

SQUID systems for geophysical time domain electromagnetics (TEM) at IPHT Jena

Forty years after the first applications of Superconducting Quantum Interference Devices (SQUIDs) [1][2] for geophysical purposes they have recently become a valued tool for mineral exploration. One of...

Dispersion Analysis of arbitrarily cut uniaxial crystals

We modified the measurement and evaluation scheme developed for the dispersion analysis of triclinic crystals to perform dispersion analysis of arbitrarily cut uniaxial crystals. In addition to the dispersion...

In situ measurements of magnetic nanoparticles after placenta perfusion

Nanoparticles (NP) present promising tools for medical applications. Nevertheless, the current lack of knowledge about their potential toxicity hinders further applications. Besides the local interactions,...

Optical detection of nanoparticle agglomeration in a living system under the influence of a magnetic field

Nanoparticles are important in diagnosis and therapy. In order to apply their potential, an understanding of the behavior of particles in the body is crucial. However, in vitro experiments usually do not...
