Journal ArticleDOI
3D analysis, modeling and simulation of transport processes in compressed fibrous microstructures, using the Lattice Boltzmann method
Dieter Froning,Jan Brinkmann,Uwe Reimer,Volker Schmidt,Werner Lehnert,Werner Lehnert,Detlef Stolten,Detlef Stolten +7 more
TL;DR: In this article, the authors combine a stochastic 3D microstructure model of a fiber-based gas diffusion layer of polymer electrolyte fuel cells with a Lattice Boltzmann model for fluid transport.
Journal ArticleDOI
3D microstructure modeling of compressed fiber-based materials
Gerd Gaiselmann,Christian Tötzke,Christian Tötzke,Ingo Manke,Werner Lehnert,Werner Lehnert,Volker Schmidt +6 more
TL;DR: In this article, a parametrized model that describes the 3D microstructure of compressed fiber-based materials is introduced, which allows to virtually generate the microstructures of realistically compressed gas-diffusion layers (GDL).
Journal ArticleDOI
Machine Learning Techniques for the Segmentation of Tomographic Image Data of Functional Materials
Orkun Furat,Mingyan Wang,Matthias Neumann,Lukas Petrich,Matthias Weber,Carl E. Krill,Volker Schmidt +6 more
TL;DR: A quantitative comparison between segmentation results indicates that the 3D U-Net performs best among the considered U-nets, where the latter was trained at a lower resolution due to memory limitations.
Journal ArticleDOI
Function and three-dimensional structure of intervessel pit membranes in angiosperms: a review
Lucian Kaack,Clemens M. Altaner,Cora Carmesin,Ana Diaz,Mirko Holler,Christine Kranz,Gregor Neusser,Michal Odstrcil,Michal Odstrcil,H. Jochen Schenk,Volker Schmidt,Matthias Weber,Ya Zhang,Ya Zhang,Steven Jansen +14 more
TL;DR: Based on perfusion experiments and modelling, pore constrictions in fibrous pit membranes are estimated to be well below 50 nm, and typically smaller than 20 nm as mentioned in this paper, which is in line with the observed xylem water potentials values that generally induce spread of embolism.
Journal ArticleDOI
High porosity with tiny pore constrictions and unbending pathways characterize the 3D structure of intervessel pit membranes in angiosperm xylem
Ya Zhang,Ya Zhang,Cora Carmesin,Lucian Kaack,Matthias M. Klepsch,Martyna M. Kotowska,Martyna M. Kotowska,Tabea Matei,H. Jochen Schenk,Matthias Weber,Paul Walther,Volker Schmidt,Steven Jansen +12 more
TL;DR: A modelling approach based on thickness measurements of fresh and fully shrunken pit membranes of seven species suggests that pit membranes represent a mesoporous medium, with the pore space characterised by multiple constrictions.
