Extracting hydrogel properties by watching hydrogel particles moving through solid ice
Yanxia Feng, Se-Hyeong Jung, Camillo Sirvinski +4
Strikingly, when hydrogel particles are embedded in ice in a temperature gradient, they move through the solid ice towards warmer temperatures, while swelling as they warm up. This…
IceCAPA: patterning particles and microorganisms at a freezing front
Isabelle M. Feller, Jakob Paulsen, Muriel Scherer +2
The ability to precisely pattern micro- and nano-scale objects on surfaces is important for a range of different applications. For example, colloidal patterning has been used to cr…
Resolving Light-Induced Structural Rearrangements in Responsive Microgels
Fabrizio Camerin, Megha Emerse, Gianpaolo Gallo +6
Optically-responsive microgels offer a versatile platform for designing adaptive soft materials with coupled light and thermal responsiveness. Control over the crosslinking degree…
Sliding or Rolling? Characterizing single-particle contacts
Simon Scherrer, Shivaprakash N. Ramakrishna, Vincent Niggel +4
Contacts between particles in dense, sheared suspensions are believed to underpin much of their rheology. Roughness and adhesion are known to constrain the relative motion of parti…
The 2024 Motile Active Matter Roadmap
Gerhard Gompper, Howard A. Stone, Christina Kurzthaler +29
Activity and autonomous motion are fundamental aspects of many living and engineering systems. Here, the scale of biological agents covers a wide range, from nanomotors, cytoskelet…
Characterizing hydrogel behavior under compression with gel-freezing osmometry
Yanxia Feng, Dominic Gerber, Stefanie Heyden +4
Hydrogels are particularly versatile materials that are widely found in both Nature and industry. One key reason for this versatility is their high water content, which lets them d…
Effect of particle stiffness and surface properties on the nonlinear viscoelasticity of dense microgel suspensions
Jacopo Vialetto, Shivaprakash N. Ramakrishna, Lucio Isa +1
Particle surface chemistry and internal softness are two fundamental parameters in governing the mechanical properties of dense colloidal suspensions, dictating structure and flow,…
Janus microswimmers are poor hydrodynamic mixers
Maximilian Bailey, Dmitry Fedosov, Federico Paratore +3
The generation of fluid flows by autophoretic microswimmers has been proposed as a mechanism to enhance mass transport and mixing at the micro- and nanoscale. Here, we experimental…
