Bridging the Modeling-Sampling Gap for Mid-Infrared Reflectance Spectroscopy of Small Particles, Films, and Fibers
<p>The concentration dependency of the mid-infrared (MIR) absorbance of bacterial spores was determined. Linear relationships (R<sup>2</sup> ≥ 0.99) were observed between the concentrations of spores and the baseline corrected peak absorbance for the amide absorbance regions, at coverages of …

XANES und MEXAFS an magnetischen Übergangsmetalloxiden : Entwicklung eines digitalen Lock-In-XMCD-Experiments mit Phasenschieber
In dieser Arbeit werden drei Lanthanmanganat-Systeme mittels SQUID-(Superconducting Quantum Interference Device) Magnetometrie und XMCD-(X-ray Magnetic Circular Dich-roism) Messungen an den jeweiligen Absorptionskanten (XANES: X-ray Absorption Near Edge Structure) sowie im kantenfernen Bereich …
