Arylic versus Alkylic-Hydrophobic Linkers Determine the Supramolecular Structure and Optoelectronic Properties of Tripodal Amphiphilic Push-Pull Thiazoles
The supramolecular structures and their constituents essentially determine the optoelectronic properties of thin films. The introduction of amphiphilicity to the constituents and interface assembly is...
PublicationsAnalysis of the polarized IR reflectance spectra of the monoclinic alpha-oxalic acid dihydrate
In contrast to the extensive molecular and crystal structure investigations on oxalic acid dehydrate (C2H2O4•2H2O, α-POX) and its deuterated analogues (α-DOX), stands the absence of a complete vibrational...
PublicationsThermal illumination limits in 3D Raman microscopy: A comparison of different sample illumination strategies to obtain maximum imaging speed
Confocal Raman microscopy is a powerful tool for material science and biomedical research. However, the low Raman scattering cross-section limits the working speed, which reduces the applicability for...
PublicationsAssembly of T-Shaped Amphiphilic Thiazoles on the Air-Water Interface: Impact of Polar Chromophore Moieties, as Well as Dipolarity and π-Extension of the Chromophore on the Supramolecular Structure
The supramolecular structure essentially determines the properties of organic thin films. In this work, we systematically investigate the influence of the chromophore on the supramolecular structure formation...
PublicationsStudies on the Controlled Release of Drugs from Magnetic Nanobiocomposites
Magnetic nanocomposites are a class of smart materials that have attracted recent interest as drug delivery systems or as medical implants. In this study, meltable nanobiocomposites (NBC) composed of biocompatible...
PublicationsSpatiotemporal Organization of Biofilm Matrix Revealed by Confocal Raman Imaging Integrated with Non-Negative Matrix Factorization Analysis
Simultaneous acquiring chemical and structural information within the biofilm matrix is vital for the cognition and regulation of biofilms, yet it remains a great challenge due to the sample complexity...
PublicationsTime-resolved study of site-specific corrosion in a single crystalline silver nanoparticle
We followed over 24 hours a corrosion process in monocrystalline triangular shaped nanoparticles at a single particle level by atomic force microscopy and optical spectroscopy techniques. We observed that...
PublicationsOn the Properties of Nanoporous SiO2 Films for Single Layer Antireflection Coating
Single layer antireflection coatings (SLAR) consisting of nanoporous silica (NP SiO2) films are developed by selective chemical etching of atomic layer deposited (ALD) Al2O3:SiO2 composite films. The reflective...
PublicationsFraternal twins: distinction between PbPc and SnPc by their switching behaviour in a scanning tunnelling microscope
In this contribution, we compare the optical absorbance behaviour and the structural properties of lead(II)-phthalocyanine (PbPc) and tin(II)-phthalocyanine (SnPc) thin films. To this end, we employ a...
PublicationsDesignable spectrometer-free index sensing using plasmonic Doppler gratings
Typical nanoparticle-based plasmonic index sensors detect the spectral shift of localized surface plasmon resonance (LSPR) upon the change of environmental index. Therefore, they require broadband illumination...
