Quantitative CARS Microscopic Detection of Analytes and Their Isotopomers in a Two-Channel Microfluidic Chip

Fast and quantitative detection of organic analytes is achieved by coherent anti-Stokes Raman scattering (CARS) microscopy using a two-channel microfluidic chip in combination with deuterated isotopomers...

Discriminating Isogenic Cancer Cells and Identifying Altered Unsaturated Fatty Acid Content as Associated with Metastasis Status, Using K-Means Clustering and Partial Least Squares-Discriminant Analysis of Raman Maps

Raman spectroscopy is a label-free, real-time diagnostic tool that shows great promise in identifying cell differences. We have evaluated the discriminatory power of Raman spectroscopy using a unique model...

Formation of Higher Borides During High-Pressure Synthesis and Sintering of Magnesium Diboride and Their Positive Effect on Pinning and Critical Current Density

Critical current density (jc) of high-pressure (2 GPa) manufactured MgB2-based superconductors depends on the amount and distribution of higher borides (MgB12) in MgB2 matrix, which in turn are determined...

Temperature- and strain-independent torsion sensor using a fiber loop mirror based on suspended twin-core fiber

The switch that wouldn’t switch – unexpected luminescence from a ruthenium(II)-dppz-complex in water

The complex [(dmcb)2Ru(dppz)](PF6)2 shows unexpected luminescence in water implying fundamentally different excited state relaxation pathways than are typically observed for complexes of this kind.

Energy-transfer parameters in a Tm/Yb doped single mode silica fiber

Energy-transfer parameters in a thulium-ytterbium doped single mode silica fiber have been determined quantitatively for the first time, to our knowledge. The principal energy-transfer parameters, estimated...

Nanoparticle Layer Deposition for Plasmonic Tuning of Microstructured Optical Fibers

Plasmonic nanoparticles with spectral properties in the UV-to-near-IR range have a large potential for the development of innovative optical devices. Similarly, microstructured optical fi bers (MOFs) represent...

Nanostructured Gold Films for SERS by Block Copolymer-Templated Galvanic Displacement Reactions

Up to now, little effort has been made to exploit large-area high-throughput patterning by block copolymer (BCP) lithography to generate nanostructured substrates with periods well below 100 nm for surface-enhanced...

Synthesis and characterization of regioselective substituted tetrapyridophenazine ligands and their Ru(II) complexes

A series of novel regioselective substituted tpphz ligands and two novel mononuclear ruthenium complexes of the type [(tbbpy)2Ru(tpphzRn)](PF6)2 (where tbbpy = 4,4′-di-tert.-butyl-2,2′-bipyridine,...

Ytterbium-Doping Related Stresses in Preforms for High-Power Fiber Lasers

Frozen-in mechanical stresses can significantly influence the optical and mechanical properties of optical fibers, especially in laser fibers for high-power operation. In the following, we will report...
