An automated approach for fringe frequency estimation and removal in infrared spectroscopy and hyperspectral imaging of biological samples
Solheim, Johanne Heitmann; Borondics, Ferenc; Zimmermann, Boris; Sandt, Christophe; Muthreich, Florian; Kohler, Achim (Journal article; Peer reviewed, 2021)In infrared spectroscopy of thin film samples, interference introduces distortions in spectra, commonly referred to as fringes. Fringes may alter absorbance peak ratios, which hampers the spectral analysis. We have previously ... -
Chemical variations in Quercus pollen as a tool for taxonomic identification: Implications for long-term ecological and biogeographical research
Muthreich, Florian; Zimmermann, Boris; Birks, Harry John Betteley; Vila-Vicosa, Carlos M; Seddon, Alistair (Journal article; Peer reviewed, 2020)Aim Fossil pollen is an important tool for understanding biogeographical patterns in the past, but the taxonomic resolution of the fossil‐pollen record may be limited to genus or even family level. Chemical analysis of ... -
Fossil pollen and spores as a tool for reconstructing ancient solar-ultraviolet irradiance received by plants: an assessment of prospects and challenges using proxy-system modelling
Seddon, Alistair; Festi, Daniela; Robson, T. Matthew; Zimmermann, Boris (Peer reviewed; Journal article, 2019)Ultraviolet-B radiation (UV-B, 280–315 nm) constitutes less than 1% of the total solar radiation that reaches the Earth's surface but has a disproportional impact on biological and ecological processes from the individual ...
