Porous NiOx Nanostructures Templated by Polystyrene-block-poly(2-vinylpyridine) Diblock Copolymer Micelles
A facile synthetic route to NiOx nanostructures using various amphiphilic polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) diblock copolymers as templates was investigated. The synthesis targets NiOx...
PublikationenA Modified Transmission Tip-Enhanced Raman Scattering (TERS) Setup Provides Access to Opaque Samples
The combination of scanning probe microscopy (SPM) and Raman spectroscopy enables chemical characterization of surfaces at highest spatial resolution. This so-called tip-enhanced Raman scattering (TERS)...
PublikationenSynthesis and Characterization of Poly(phenylacetylene)s with Ru(II) Bis-Terpyridine Complexes in the Side-Chain
An alkyne-functionalized ruthenium(II) bis-terpyridine complex is directly copolymerized with phenylacetylene by alkyne polymerization. The polymer is characterized by size-exclusion chromatography (SEC),...
PublikationenA multipurpose SQUID receiver for electromagnetic measurements
Geophysical exploration is getting more and more difficult – many of the easy explorable ore-bodies are exploited or under production. Finding new mines requires new technologies and tools. Transient...
PublikationenLow-temperature anodic bonding using thin-films of lithium-niobate-phosphate glass
This paper reports on the investigation of a low-temperature anodic bonding process with layers of a lithium-niobate-phosphate glass on chip level. The glass layers are deposited by means of rf sputtering....
PublikationenAll-fiber time-delay spectrometer based on an array of fiber Bragg gratings
We have investigated the possibility to use a step-chirped fiber Bragg grating array for a time-delay-spectrometer. This concept allows a simultaneous spectral and temporal characterization of pulsed light...
PublikationenObservation of Discrete, Vortex Light Bullets
We report the first experimental observation of Vortex Light Bullets which are discrete, spatiotemporal, solitary waves with orbital angular momentum. We analyze conditions for their existence and investigate...
PublikationenSQUID-based absolute vector magnetometer
The aim of this work is to measure the absolute Earth’s magnetic field components in a mobile operation with high precision. Due to their periodic voltage-flux characteristics, SQUIDs are not able to...
PublikationenPlasmonics – principles and applications
Plasmonics is a field of research investigating electromagnetic modes coupled to metal-dielectric interfaces and metal nanostructures. These modes are spatially confided bellow the wavelength of the light...
PublikationenMicrowave characterisation of nanomechanical resonator
There are a variety of methods for measuring the characteristics of nanoscale resonators. In either of these methods it is necessary to transform the mechanical vibrations of nanoscale mechanical resonator...
