Substrate contact angle governs microgel shape, stiffness and deposition pattern
M. Friederike Schulte, Sebastian S. Meyer, Timon Kratzenberg +7
Soft microgels are widely used as deformable building blocks for two-dimensional assemblies, yet solid substrates are often treated as passive supports after interfacial deposition…

Light-propelled microparticles based on symmetry-broken refractive index profiles
Julian Jeggle, Matthias Rüschenbaum, Adrian Paskert +7
Active colloidal microparticles require reliable actuation to sustain directed motion. Light-based propulsion is particularly attractive as it provides persistent energy supply and…

Changing the flow profile and resulting drying pattern of dispersion droplets via contact angle modification
Carmen Morcillo Perez, Benjamin D. Goddard, Theo Reid +4
Spilling tea or coffee leads to a tell-tale circular stain after the droplet dries, known as the "coffee ring effect". The evaporation of suspension droplets is a complex physical…
