Rapid Raman spectroscopic analysis of stress induced degradation of the pharmaceutical drug tetracycline

Stress factors caused by inadequate storage can induce the unwanted degradation of active compounds in pharmaceutical formulations. Resonance Raman spectroscopy is presented as an analytical tool for rapid...

New approaches in component design for dye-sensitized solar cells

The present perspective presents a number of issues related to the current direction of DSSC research, with emphasis on the transition from iodide-containing electrolyte to charge-transport media (CTMs),...

Automated and fast identification of resistant E. coli against the lead drugs of the 3MRGN group using specific Raman marker bands

A Raman-based, strain-independent, semi-automated method is presented which allows the rapid (< 3hours) determination of antibiotic susceptibility of bacterial pathogens isolated from clinical samples....

An epidemic CC1-MRSA-IV clone yields false negative test results in molecular MRSA identification assays: a note of caution

We investigated why a clinical meticillin-resistant Staphylococcus aureus (MRSA) isolate yielded false-negative results with some commercial PCR tests for MRSA detection. We found that an epidemic European...

Response of the wood-decay fungus Schizophyllum commune to co-occurring microorganisms

Microorganisms are constantly interacting in a given environment by a constant exchange of signaling molecules. In timber, wood-decay fungi will come into contact with other fungi and bacteria. In naturally...

Optical microresonator arrays of fluorescence-switchable diarylethenes with unreplicable spectral fingerprints

High-security identification requires authentication that is hard to counterfeit and replicate. For anti-counterfeiting data storage and rewritable memory devices, chromic materials are adoptable, where...

Deep learning as phase retrieval tool for CARS spectra

Increased static dielectric constant in ZnMnO and ZnCoO thin films with bound magnetic polarons

A novel small signal equivalent circuit model is proposed in the inversion regime of metal/(ZnO, ZnMnO, and ZnCoO) semiconductor/Si3N4 insulator/p-Si semiconductor (MSIS) structures to describe the distinctive...

Charged domains in ferroelectric, polycrystalline yttrium manganite thin films resolved with scanning electron microscopy

We have investigated ferroelectric charged domains in polycrystalline hexagonal yttrium manganite thin films (Y1Mn1O3, Y0.95Mn1.05O3, Y1Mn0.99Ti0.01O3, and Y0.94Mn1.05Ti0.01O3) by scanning electron microscopy...

Revisiting longitudinal optical modes in materials with plasmon and plasmon-like absorptions – SrTiO3 and β-Ga2O3

We investigate exemplary the longitudinal optical (LO) mode order in compounds with a plasmon or plasmon-like phonon mode and additional phonon modes. When the oscillator strength of the plasmon or plasmon-like...
