Insights into the Mechanism of Polymer Coating Self-Healing Using Raman Spectroscopy
Self-healing polymer coatings are an emerging class of smart materials. Upon mechanical damage the material properties may be restored by self-healing, which can be triggered externally, e.g. by an increased...
PublikationenDispersion analysis of triclinic K2Cr2O7
Polarized IR-reflection spectra of a single crystal of K2Cr2O7 were recorded at near normal incidence. Dispersion analysis was applied, taking fully into account the triclinic symmetry of the crystal and...
PublikationenOptical properties of cerium-codoped high power laser fibers
The photodarkening resistivity of ytterbium doped alumosilicate fibers can be remarkably improved by cerium codoping. Here we report on systematical investigations of the influence of cerium on an optimized...
PublikationenDominant Vinculin Binding Angle in Podosomes Revealed by High Resolution Optical Microscopy
Podosomes are dynamic actin-rich cell-matrix adhesion sites of migrating and invasive cells such as macrophages and osteoclasts, and are receiving increasing attention due to their possible involvement...
PublikationenA Heteroleptic Bis(tridentate) Ruthenium(II) Platform Featuring an Anionic 1,2,3-Triazolate-Based Ligand for Application in the Dye- Sensitized Solar Cell
A series of bis(tridentate) ruthenium(II) complexes featuring 2,2′:6′,2′′-terpyridine, functionalized with anchoring groups, and new anionic 1,2,3-triazolate-based tridentate ligands is presented....
PublikationenDetection 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...
PublikationenMeasurement 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...
PublikationenSpatially 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...
PublikationenPhysicochemical 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)...
PublikationenLight-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...
