Life at Low Reynolds Number: Why a Micron-Scale Swimmer Cannot Coast
Cut a swimmer down to a few microns and inertia disappears entirely. What is left is a world where motion stops the instant the pushing does, and where symmetry decides whether you go anywhere at all.
The Society of Rheology Turns 97: Colloids and Soft Matter Head to Boston This October
The 97th Annual Meeting of The Society of Rheology runs October 25-29 in Boston. The poster and Gallery of Rheology deadline is August 14 — here is why colloid and soft matter researchers should look.
A 70-Year-Old Dispersion Law Meets Self-Propelled Swimmers
Does the classic Taylor-Aris dispersion law survive when the particles swim on their own? A microfluidic experiment with live microalgae says yes.
Moving the Magnet Off-Center: Designing What a Colloid Builds
Group member Jonathan Victoria-Camacho shows that shifting a magnetic particle's dipole away from its center changes which structures it assembles into — loops, worms, chains, and more.
Why Some Colloids Stay Suspended and Others Clump: DLVO Theory and the Electric Double Layer
Whether milk stays milky or mud settles out comes down to a contest between two forces acting across nanometers. DLVO theory keeps the score.
Professional Services Opportunity: Project Coordinator
Seeking a highly organized and proactive Project Coordinator to support research and innovation initiatives through project management, proposal development, administrative coordination, and stakeholder engagement in a dynamic academic environment.

From Target to Particle: Inverse Design Comes to Colloidal Self-Assembly
Generative models, surrogate optimization, and reinforcement learning are flipping the colloidal self-assembly workflow from forward to reverse.
One Hundred Years of Colloid Science: The ACS CSSS Centennial Convenes at Delaware
The 100th ACS Colloid and Surface Science Symposium meets June 21–24 at the University of Delaware — a centennial edition with special historical programming and the full breadth of the field on the agenda.
Sensory Delay as a Feature: Janus Microswimmers That Adapt to Light and Chemistry
New Janus microswimmers self-regulate propulsion speed in response to light and dissolved chemicals. A built-in sensory delay makes their localization sharper, not slower.

Diffusiophoresis: When a Concentration Gradient Moves a Particle
A dissolved salt can push colloidal particles without any fluid flow. Diffusiophoresis explains the mechanism — and why it matters across soft matter.
