Shear stress during self-assembly encodes stiffness of network-based materials
Lens M. Dedroog, Olivier Deschaume, Carmen Bartic +4
The mechanical properties of network-based materials have been extensively studied under qui- escent conditions, yet their self-assembly in nature occurs mainly in a mechanically s…
Capillary force-driven particle orientation in rod networks
Lingyue Liu, Sebastian Gassenmeier, Erin Koos
Hypothesis: Anisotropic rod particles in capillary suspensions form complex network structures with distinctive orientation patterns and rheological properties that differ signific…
Dewetting Fingering Instability in Capillary Suspensions: Role of Particles and Liquid Bridges
Lingyue Liu, Mete Abbot, Philipp Brockmann +3
This study investigates the fingering instability that forms during stretching of capillary suspensions with and without added nanoparticles. The dewetting process is observed usin…
Hierarchical materials with interconnected pores from capillary suspensions for bone tissue engineering
Souhaila Nider, Femke De Ceulaer, Berfu Göksel +2
The increasing demand for bone grafts due to the aging population has opened new opportunities for the manufacture of porous ceramics to assist in bone reconstruction. In our study…
Enhanced contact flexibility from nanoparticles in capillary suspensions
Lingyue Liu, Jens Allard, Erin Koos
Hypothesis: Sample-spanning particle networks are used to induce structure and a yield stress, necessary for 3D printing of porous ceramics and paints. In capillary suspensions, a…
Effects of particle roughness on the rheology and structure of capillary suspensions
Jens Allard, Sanne Burgers, Miriam Candelaria Rodríguez González +3
We show that particle roughness leads to changes in the number, shape and resulting capillary force of liquid bridges in capillary suspensions. We created fluorescently labeled, ra…
The behavior of capillary suspensions at diverse length scales: from single capillary bridges to bulk
Sebastian Bindgen, Jens Allard, Erin Koos
Liquid-liquid-solid systems are becoming increasingly common in everyday life with many possible applications. Here, we focus on a special case of such liquid-liquid-solid systems,…
Lees-Edwards boundary conditions for translation invariant shear flow: implementation and transport properties
Sebastian Bindgen, Florian Weik, Rudolf Weeber +2
Molecular dynamics (MD) simulations represent a powerful investigation tool in the field of soft matter. By using shear flows, one can probe the bulk rheology of complex fluids, al…
Particle contact dynamics as the origin for non-integer power expansion rheology in attractive suspension networks
Irene Natalia, Randy H. Ewoldt, Erin Koos
We show that Hertzian particle contacts are the underlying cause of the as-yet-unexplained noninteger power laws in weakly nonlinear rheology. In the medium amplitude oscillatory s…
Influence of drying conditions on the stress and weight development of capillary suspensions
Steffen B. Fischer, Erin Koos
Cracking of suspensions during drying is a common problem. While additives, e.g. binders and surfactants, can mitigate this problem, some applications, such as printing conductive…
Using an added liquid to suppress drying defects in hard particle coatings
Steffen B. Fischer, Erin Koos
Hypothesis: Lateral accumulation and film defects during drying of hard particle coatings is a common problem, typically solved using polymeric additives and surface active ingredi…
Connecting particle clustering and rheology in attractive particle networks
Sebastian Bindgen, Frank Bossler, Jens Allard +1
The structural properties of suspensions and other multiphase systems are vital to overall processability, functionality and acceptance among consumers. Therefore, it is crucial to…
Capillary suspensions: Particle networks formed through the capillary force
Erin Koos
The addition of small amounts of a secondary fluid to a suspension can, through the attractive capillary force, lead to particle bridging and network formation. The capillary bridg…
Restructuring and aging in a capillary suspension
Erin Koos, Wolfgang Kannowade, Norbert Willenbacher
The rheological properties of capillary suspensions, suspensions with small amounts of an added immiscible fluid, are dramatically altered with the addition of the secondary fluid.…
