3D (x-y-t) Raman imaging of tomato fruit cuticle: Microchemistry during development Open

Ana González Moreno, Eva Domίnguez, Konrad Mayer, Nannan Xiao, P. Bock , et al. · 2022

The cuticle is a protective extracellular matrix that covers the above-ground epidermis of land plants. Here, we studied the cuticle of tomato (Solanum lycopersicum L.) fruits in situ using confocal Raman microscopy. Microsections from cut…

3D (x-y-t) Raman imaging of tomato fruit cuticle: microchemistry during development Open

Ana González Moreno, Eva Domίnguez, Konrad Mayer, Nannan Xiao, P. Bock , et al. · 2022

The cuticle of tomato fruits was studied in-situ using Confocal Raman Microscopy. Microsections from cuticles isolated at different developmental stages were scanned to reveal the distribution of cuticle components with a spatial resolutio…

A Guide to Elucidate the Hidden Multicomponent Layered Structure of Plant Cuticles by Raman Imaging Open

P. Bock, Martin Felhofer, Konrad Mayer, Notburga Gierlinger · 2021

The cuticle covers almost all plant organs as the outermost layer and serves as a transpiration barrier, sunscreen, and first line of defense against pathogens. Waxes, fatty acids, and aromatic components build chemically and structurally …

Twist and lock: nutshell structures for high strength and energy absorption Open

Nannan Xiao, Martin Felhofer, Sebastian J. Antreich, Jessica C. Huss, Konrad Mayer , et al. · 2021

Nutshells achieve remarkable properties by optimizing structure and chemistry at different hierarchical levels. Probing nutshells from the cellular down to the nano- and molecular level by microchemical and nanomechanical imaging technique…

Hybrid mineral predictive mapping with self-organizing maps and a multilayer perceptron applied to tin deposits in the Erzgebirge, Germany Open

Andreas Brosig, Andreas Barth, Peggy Hielscher, Claus Legler, Stefan Schäfer , et al. · 2021

<p>Self-organizing maps (SOM) are a useful tool to analyze and interpret gridded datasets like potential field or stream sediment geochemistry data. The data are transformed from geographic space to SOM space where they can be cluste…

Raman imaging reveals in-situ microchemistry of cuticle and epidermis of spruce needles Open

Nadia Sasani, P. Bock, Martin Felhofer, Notburga Gierlinger · 2021

Background The cuticle is a protective layer playing an important role in plant defense against biotic and abiotic stresses. So far cuticle structure and chemistry was mainly studied by electron microscopy and chemical extraction. Thus, an…

Oak wood drying: precipitation of crystalline ellagic acid leads to discoloration Open

Martin Felhofer, P. Bock, Nannan Xiao, Christoph Preimesberger, Martin Lindemann , et al. · 2021

Oak heartwood usually darkens during and after drying. This darkening can be heterogeneous, leaving non-colored areas in the wood board. These light discolorations have been linked to heterogeneous distribution of tannins, but compelling e…

From the Soft to the Hard: Changes in Microchemistry During Cell Wall Maturation of Walnut Shells Open

Nannan Xiao, P. Bock, Sebastian J. Antreich, Yannick M. Staedler, Jürg Schönenberger , et al. · 2020

The walnut shell is a hard and protective layer that provides an essential barrier between the seed and its environment. The shell is based on only one unit cell type: the polylobate sclerenchyma cell. For a better understanding of the int…

Wood Deformation Leads to Rearrangement of Molecules at the Nanoscale Open

Martin Felhofer, P. Bock, Adya P. Singh, Batirtze Prats‐Mateu, Ronald Zirbs , et al. · 2020

Wood, as the most abundant carbon dioxide storing bioresource, is currently driven beyond its traditional use through creative innovations and nanotechnology. For many properties the micro- and nanostructure plays a crucial role and one ke…

Improving noise estimation based on air in the trachea with a volume-based approach Open

Hendrik Joost Wisselink, Gert Jan Pelgrim, Mieneke Rook, M. P. van den Berge, P. Bock , et al. · 2020

Poster: ECR 2020 / C-11585 / Improving noise estimation based on air in the trachea with a volume-based approach by: H. J. Wisselink , G. J. Pelgrim, M. Rook, M. P. van den Berge, P. D. G. de bock, R. Vliegenthart; Groningen/NL

Infrared and Raman spectra of lignin substructures: Dibenzodioxocin Open

P. Bock, Paula Nousiainen, Thomas Elder, Markus Blaukopf, Hassan Amer , et al. · 2020

Vibrational spectroscopy is a very suitable tool for investigating the plant cell wall in situ with almost no sample preparation. The structural information of all different constituents is contained in a single spectrum. Interpretation th…

Infrared and Raman spectra of lignin substructures: Coniferyl alcohol, abietin, and coniferyl aldehyde Open

P. Bock, Notburga Gierlinger · 2019

Anatomical and chemical information can be linked by Raman imaging. Behind every pixel of the image is a Raman spectrum, which contains all the information as a molecular fingerprint. Yet to understand the spectra, the bands have to be ass…

Following laser induced changes of plant phenylpropanoids by Raman microscopy Open

Batirtze Prats‐Mateu, P. Bock, Martina Schroffenegger, José L. Toca‐Herrera, Notburga Gierlinger · 2018

Antifungal stilbene impregnation: transport and distribution on the micron-level Open

Martin Felhofer, Batirtze Prats‐Mateu, P. Bock, Notburga Gierlinger · 2018

The transition from the living water-transporting sapwood to heartwood involves in many tree species impregnation with extractives. These differ in amount and composition, and enhance resistance against bacteria, insects or fungi. To under…
