Packing soft spheres: experimental demonstrations with hydrogels
Hutzler, Stefan; Weaire, Denis (2023)We describe a number of different experimental set-ups that use hydrogel spheres to demonstrate dense packings of deformable spheres in various geometries. The arrangements are similar to those of bubbles in foams, ... -
Physical models of infant mortality: implications for defects in biological systems
Hutzler, Stefan; Richmond, Peter (2020)Reliability engineering concerned with failure of technical inanimate systems usually uses the vocabulary and notions of human mortality, e.g., infant mortality vs. senescence mortality. Yet, few data are available to ... -
Physics in a small bedroom
Hutzler, Stefan; Weaire, Denis (Springer, 2022) -
Properties of lightweight fibrous structures made by a novel foam forming technique
Hutzler, Stefan; Moebius, Matthias (2019)We describe a novel method for the production of lightweight fibrous structures of densities as low as 8.8 kg m−3 . The method is based on the use of liquid foam as a carrier medium for dispersed Kraft fibres. Different ... -
A simple experimental system to illustrate the nonlinear properties of a linear chain under compression.
Hutzler, Stefan; Weaire, Denis (2020)A linear chain of spheres confined by a transverse harmonic potential experiences localized buckling under compression. We present simple experiments using gas bubbles in a liquid-filled tube to demonstrate this phenomenon. ... -
Stability maps for columnar structures
Hutzler, Stefan; Weaire, Denis (2023)We have previously explored the hysteresis and reversibility of transitions between ordered packings of soft spheres of diameter d in cylindrical channels of diameter D [A. Mughal, J. Winkelmann, D. Weaire, S. Hutzler, ... -
Theory of rotational columnar structures of soft spheres
Hutzler, Stefan; Weaire, Denis; Winkelmann, J.; Mughal, A.; Williams, D.B. (2019)There is a growing interest in cylindrical structures of hard and soft particles. A promising new method to assemble such structures has recently been introduced by Lee et al. [T. Lee, K. Gizynski, and B. Grzybowski, ... -
Variation of average coordination number with liquid fraction for two-dimensional foams with finite contact angle
Hutzler, Stefan (2021)We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at which liquid films and Plateau borders meet is non-zero. We determine the average coordination number Z of bubbles ...
