Photoluminescence of samples produced by Electroless Wet Chemical Etching: Between silicon nanowires and porous structure
Samples containing silicon nanowires (Si-NWs) and highly porous structures (P-Si) were prepared by ElectrolessWet Chemical Etching (EWCE) of crystalline silicon wafers using various etching parameters....
PublikationenMagnetic multicore nanoparticles for hyperthermia – influence of particle immobilisation in tumour tissue on magnetic properties
When using magnetic nanoparticles as heating source for magnetic particle hyperthermia it is of particular interest to know if the particles are free to move in the interstitial fluid or fixed to the tumour...
PublikationenInvestigations on magnetic particles prepared by cyclic growth
Magnetic iron oxide nanoparticles are promising tools for medical applications like hyperthermia or magnetic drug targeting. The relevant properties in these applications strongly depend on particle size...
PublikationenReinvestigation of the M Emission Spectrum of Uranium-92
The M spectrum of the element uranium was reinvestigated by using both high-resolution wavelength dispersive (WD) spectrometry as well as energy dispersive (ED) pectrometry. Thereby we observed relative...
PublikationenGrowth of axial SiGe heterojunctions in nanowires using PLD
Axial heterojunctions between pure silicon and pure germanium in nanowires have been realized combining pulsed laser deposition, chemical vapor deposition and electron beam evaporation in a vapor-liquid-solid...
PublikationenMolecular Plasmonics – light meets molecules at the nanoscale
Certain metal nanoparticles exhibit the effect of localized surface plasmon resonance when interacting with light, based on collective oscillations of their conduction electrons. The interaction of this...
PublikationenNanoscale structural analysis using tip-enhanced Raman spectroscopy
Tip-enhanced Raman scattering (TERS) enables the label free investigation of biochemical interfaces with nanometer lateral resolution by combining the benefits of the intrinsic molecular specificity of...
PublikationenVisualization and characterisation of defined hair follicle compartments by Fourier transform infrared (FTIR) imaging without labelling
Background: To visualise and characterise skin architecture, the tissue usually has to be destroyed and labelled. Objectives: The use of Fourier transform infrared (FTIR) spectroscopy as a label-free,...
PublikationenTip-Enhanced Raman Scattering (TERS) from Hemozoin Crystals within a Sectioned Erythrocyte
Tip-enhanced Raman scattering (TERS) is a powerful technique to obtain molecular information on a nanometer scale, however, the technique has been limited to cell surfaces, viruses, and isolated molecules....
PublikationenTuning of photocatalytic hydrogen production and photoinduced intramolecular electron transfer rates by regioselective bridging ligand substitution
Artificial photosynthesis based on supramolecular photocatalysts offers the unique possibility to study the molecular processes underlying catalytic conversion of photons into chemical fuels in great...
