Light-absoption selection of nanoparticles and nanofluids containing nanoparticles for their effective heating by solar radiation
Light-absorption selection of single nanoparticle for solar radiation requires the simultaneous fulfillment of all of the following novel conditions—maximal close (overlap) of the dependence of nanoparticle...
PublikationenResonance-enhanced multi-octave supercontinuum generation in antiresonant hollow-core fibers
Ultrafast supercontinuum generation in gas-filled waveguides is one enabling technology for many intriguing application ranging from attosecond metrology towards biophotonics, with theamount of spectral...
PublikationenAnalysis of nanogap-induced spectral blue-shifts of plasmons on fiber-integrated gold, silver and copper nanowires
We analyze the properties of HE2 surface plasmon polaritons on fiber-integrated gold, silver and copper nanowires and find a systematic blue-shift of the measured resonance wavelengths which we attribute...
PublikationenChemical and Electrochemical Synthesis of Platinum Black
We present electrochemical and chemical synthesis of platinum black at room temperature in aqueous and non-aqueous media. X-ray analysis established the purity and crystalline nature. The electron micrographs...
PublikationenDual-scattering near-field microscope for correlative nanoimaging of SERS and electromagnetic hotspots
Surface-enhanced Raman spectroscopy (SERS) enables sensitive chemical studies and materials identification, relying on electromagnetic (EM) and chemical-enhancement mechanisms. Here we introduce a tool...
Publikationen[FeFe]-Hydrogenase H-cluster mimics mediated by naphthalene monoimide derivatives of peri-substituted dichalcogenides
Synthetic models of the active site of [FeFe]-hydrogenase containing naphthalene monoimide (NMI) of peri-substituted dichalcogenides as bridging linker have been prepared and characterized using different...
PublikationenMastering high resolution tip-enhanced Raman spectroscopy: Towards a shift of perception
The recent years have seen tremendous improvement of our understanding of high resolution reachable in TERS experiments, forcing us to re-evaluate our understanding of the intrinsic limits of this field,...
PublikationenTip-enhanced Raman spectroscopy – from early developments to recent advances
An analytical technique operating at the nanoscale must be flexible regarding variable experimental conditions while ideally also being highly specific, extremely sensitive, and spatially confined. In...
PublikationenCorrection of mosaicking artefacts in multimodal Images caused by uneven illumination
Recent advances in nonlinear multimodal imaging, eg, the combination of coherent anti-Stokes Raman scattering, 2-photon excited autofluorescence, and second-harmonic generation, have shown the great potential...
PublikationenLow-Threshold Whispering Gallery Mode Lasing from Self-Assembled Microspheres of Single-Sort Conjugated Polymers
Low-threshold organic microlasers are demanded for advanced optical applications such as nano/micrometer scale memory, sensing, and communication tools, and further valuable for future electrically driven...
