Atomistic Framework for Glassy Polymer Viscoelasticity Across Twenty Frequency Decades
Ankit Singh, Vinay Vaibhav, Caterina Czibula +6
Glassy polymers are central to engineering applications, yet their viscoelastic response over broad frequency and temperature ranges remains difficult to characterize. We extend no…
The potential of Brillouin Spectroscopy for investigating the mechanical properties of hydrogels during dehydration
Caterina Czibula, Mónica G. Simoes, Manfred H. Ulz +4
Hydrogels are attractive and versatile gel-based structures consisting of three-dimensional networks of hydrophilic polymers with unique properties that can retain a large amount o…
Combining Brillouin spectroscopy and machine learned interatomic potentials to probe mechanical properties of metal organic frameworks
Florian P. Lindner, Nina Strasser, Martin Schultze +6
The mechanical properties of metal-organic frameworks (MOFs) are of high fundamental and also practical relevance. A particularly intriguing technique for determining anisotropic e…
AFM-based low frequency viscoelastic characterization of wood pulp fibers at different relative humidity
Caterina Czibula, Tristan Seidlhofer, Christian Ganser +2
The viscoelastic behavior of wood pulp fibers plays a fundamental role in the performance of paper and paper products. Wood pulp fibers are hierarchical composites consisting of di…
