Two-photon lasing by a superconducting qubit

We study the response of a magnetic-field-driven superconducting qubit strongly coupled to a superconducting coplanar waveguide resonator. We observed a strong amplification/damping of a probing signal...

Synthesis and characterization of an immobilizable photochemical molecular device for H2-generation

With [RuII(bpyMeP)2tpphzPtCl2]2+ (4) a molecular photocatalyst has been synthesized for visible-lightdriven H2-evolution. It contains the ligand bpyMeP (4,4’-bis(diethyl-(methylene)-phosphonate)-2,2’-...

And yet they glow: thiazole based push–pull fluorophores containing nitro groups and the influence of regioisomerism

Reported is a study on the influence of regioisomerism on the photophysical properties in 4-hydroxy-1,3-thiazole based push-pull-chromophores/fluorophores to evaluate the molecular structure-property relationship...

Surface- and tip-enhanced Raman spectroscopy reveals spin-waves in iron oxide nanoparticles

Nanomaterials have the remarkable characteristic of displaying physical properties different from their bulk counterparts. An additional degree of complexity and functionality arises when oxide nanoparticles...

Nanoscale Heterogeneity of the Molecular Structure of Individual hIAPP Amyloid Fibrils Revealed with Tip-Enhanced Raman Spectroscopy

Type 2 diabetes mellitus is characterized by the pathological deposition of fibrillized protein, known as amyloids. It is thought that oligomers and/or amy- loid fibrils formed from human islet amyloid...

Label-free monitoring of plasmonic catalysis on the nanoscale

Plasmonics is describing specific light mater interactions of metallic structures. In general the size of such structures is well in the nanometer regime and also determines specific behaviors like color,...

Fiber probe for nonlinear imaging applications

Over the past years it had been demonstrated that multimodal imaging combining the nonlinear modalities coherent anti-Stokes Raman scattering (CARS), two-photon excited auto-fluorescence (TPEF) and second...

Dielectrophoresis based integration of nanostructures and their sensorial application

Microbial respiration and natural attenuation of benzene contaminated soils investigated by cavity enhanced Raman multi-gas spectroscopy

Soil and groundwater contamination with benzene can cause serious environmental damage. However, many soil microorganisms are capable to adapt and are known to strongly control the fate of organic contamination....

Detailed numerical investigation of the interaction of longitudinal acoustic waves with fiber Bragg gratings in suspended-core fibers

The interaction between longitudinal acoustic waves and fiber Bragg gratings in suspended-core optical fibers is numerically investigated. The fiber core size and the air hole size are varied, and the...
