Deviations from Beer’s law on the microscale – Nonadditivity of absorption cross sections
Beer’s law assumes a linear dependence of absorbance on concentration, accordingly the index of absorption and the molar attenuation coefficient are material properties and the absorption cross section,...
PublikationenIsolation matters – processing blood for Raman microspectroscopic identification of bacteria
Bacteremia with its high mortality is a frequent case in clinical health care. Further, bacteremia includes the considerable risk of progressing to a sepsis. Even in case of survival, sepsis still entails...
PublikationenMolecular Characterization and Comparative Genomics of Clinical Hybrid Shiga Toxin-Producing and Enterotoxigenic Escherichia coli (STEC/ETEC) Strains in Sweden
Hybrid E. coli pathotypes are representing emerging public health threats with enhanced virulence from different pathotypes. Hybrids of Shiga toxin-producing and enterotoxigenic E. coli (STEC/ETEC) have...
PublikationenShort Communication: Diversity of staphylococci isolated from sheep mastitis in northern Algeria
Mastitis in ruminants is an important disease with major effects on both the economy and animal welfare. It is caused by major pathogens such as Staphylococcus aureus and minor pathogens such as coagulase-negative...
PublikationenAnalysis of viscosity data in As2Se3, Se and Se95Te5 chalcogenide melts using the pressure assisted melt filling technique
The pressure-assisted melt filling technique (PAMFT) is promising approach for integrating new materials such as glasses or semiconductor into fiber, while only a small amount of starting material (<...
PublikationenTrendbericht Physikalische Chemie: Halbleiternanokristalle in der lichtgetriebenen Wasserspaltung
Wie effizient photokatalytische Wasserstoffversorgung abläuft, hängt von Elektronen- und Lochtransferprozessen ab. Diese lassen sich besonders gut an Halbleiternanokristallen untersuchen. Cadmiumchalkogenide...
PublikationenSuperexchange on the Fast Lane – Intramolecular electron transfer in a molecular triad occurs by conformationally-gated superexchange
Photoinduced electron transfer via hopping is generally considered to have a stronger temperature dependence than electron transfer via superexchange. However, in this work, an opposite trend of the temperature...
PublikationenMeasuring nanoscale diffusion dynamics in cellular membranes with super-resolution STED–FCS
Super-resolution microscopy techniques enable optical imaging in live cells with unprecedented spatial resolution. They unfortunately lack the temporal resolution required to directly investigate cellular...
PublikationenRaman ChemLighter: Fiber-optic Raman probe imaging in combination with augmented chemical reality
Raman spectroscopy using fiberoptic probe combines non-contacted and label-free molecular fingerprinting with high mechanical flexibility for biomedical, clinical, and industrial applications. Inherently,...
PublikationenSynergy of photoinduced force microscopy and tip-enhanced Raman spectroscopy – a correlative study on MoS2
In this contribution, we combine for the first time tip-enhanced Raman spectroscopy (TERS) and photoinduced force microscopy (PiFM) synergistically and examine this instrumental approach on the 2D material...
