Multimodal nonlinear microscopic investigations on head and neck squamous cell carcinoma: Toward intraoperative imaging
Background. Prognosis and appropriate treatment of head and neck squamous cell carcinoma (HNSCC) depend on the tumor type routinely derived by invasive histopathology. A promising non-invasive alternative...
PublicationsHalbleiter-Nanodrähte: flexible Bausteine für neuartige optische Anwendungen
Im Bereich der angewandten Physik bildet die Erforschung der optischen Eigenschaften von Halbleiter-Nanodrähten und deren kontrollierte Modifizierung die Basis für vielfältige Anwendungen vom diagnostischen...
PublicationsApproximation of the effective refractive index of surface plasmons propagating along micron-sized gold wires in photonic crystal fibers
Since the first presentation of selectively metal filled photonic crystal fibers (PCFs) in 2008, a lot of work and effort has been put in the understanding of propagation characteristics of such fibers...
PublicationsThe influence of the drawing process on the intrinsic stress in optical fibers and the arising possibility to optimize the birefringence of PM fibers
The properties of optical fibers can significantly be influenced by intrinsic stress. It is well known that these stresses are caused by various reasons, e.g. the variations in the thermal expansion coefficient...
PublicationsMulti-kW single fiber laser based on an extra large mode area fiber design
The quality of Yb-doped fused bulk silica produced by sintering of Yb-doped fused silica granulates has improved greatly in the past five years [1 – 4]. In particular, the refractive index and doping...
PublicationsClassification of inflammatory bowel diseases by means of Raman spectroscopic imaging of epithelium cells
The present study reports about a Raman microspectroscopic characterization of the inflammatory bowel diseases Crohn’s disease and ulcerative colitis. Therefore, Raman maps of human colon tissue sections...
PublicationsA Study of Docetaxel induced effects in MCF-7 Cells by means of Raman microspectroscopy
Chemotherapies feature a low success rate of about 25%, and therefore, the choice of the most effective cytostatic drug for the individual patient and monitoring the efficiency of an ongoing chemotherapy...
PublicationsSynthesis and Characterization of Poly(methylmethacrylate) Backbone Polymers Containing Side-Chain Pendant Ruthenium(II) Bis-Terpyridine Complexes With an Elongated Conjugated System
A series of functionalized methacrylate monomers has been polymerized utilizing the reversible addition–fragmentation chain transfer (RAFT) polymerization procedure in order to synthesize side-chain...
PublicationsDiffusion coefficients of boron in vitreous silica at high temperatures
The diffusion of boron in yB2O3(1-y)SiO2 glasses with up to 8 mol% B2O3 was investigated by annealing doped layers on the inner surface of quartz glass tubes between 1700°C and 2000°C and measuring radial...
PublicationsSynthesis and Characterization of Polymetharylates Containing Conjugated Oligo(phenylene ethynylene)s as Side Chains
A series of methacrylates containing rigid π-conjugated oligo(phenylene ethynylenes) with different size of the conjugated system (M I – M III) and therefore optoelectronic properties were synthesized...
