Detection and Discrimination of Non-Melanoma Skin Cancer by Multimodal Imaging
Non-melanoma skin cancer (NMSC) belongs to the most frequent human neoplasms. Its exposed location facilitates a fast ambulant treatment. However, in the clinical practice far more lesions are removed...
PublicationsMeasurement of higher-order mode propagation losses in effectively single mode fibers
We present a direct and nondestructive measurement of the propagation loss of higher-order modes (HOMs) in effectively single-mode fibers. Lossy HOMs are excited by applying local stress at various points...
PublicationsSpatially resolved single photon detection with a quantum sensor array
We propose a method of resolving a spatially coherent signal, which contains on average just a single photon, against the background of local noise at the same frequency. The method is based on detecting...
PublicationsPhysicochemical analysis of ruthenium(II) sensitizers of 1,2,3-triazole-derived mesoionic carbene and cyclometalating ligands
A series of heteroleptic bis(tridentate) ruthenium(II) complexes bearing ligands featuring 1,2,3-triazolide and 1,2,3-triazolylidene units are presented. The synthesis of the C^N^N-coordinated ruthenium(II)...
PublicationsLight-harvesting of polymerizable 4-hydroxy-1,3-thiazole monomers by energy transfer toward photoactive Os(II) metal complexes in linear polymers
A polymer library consisting of a series of three fluorescing monomers (i.e., blue, yellow and redemitting) based on 4-hydroxy-1,3-thiazole chromophores as well as an Os(II) metal complex containing monomer...
PublicationsPorous 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...
PublicationsA 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)...
PublicationsSynthesis 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),...
PublicationsA 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...
PublicationsLow-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....
