Liquids and Complex Fluids Group

This is an IOP special interest group, which is a community of IOP members focused on a particular discipline, application or area of interest. 

Special interest groups allow members to connect and share knowledge and ideas. The IOP funds groups to deliver a range of activities including events, prizes and bursaries. All of our groups are driven by members.  

About the group

As a special interest, member-driven group, we are interested in the structure and dynamics of liquids and complex fluids, from microscopic to mesoscopic and macroscopic length scales. Our work encompasses systems that range from “simple” liquids to complex fluids and soft materials.

These include:

  • emulsions, suspensions and colloids
  • gels and foams
  • polymers and membranes
  • liquid mixtures and solvation phenomena
  • interfacial phenomena, confined liquids and wetting
  • liquid crystals
  • active matter
  • crystal growth in liquids and self-assembly from solution
  • glass transition and arrested states of matter
  • fluids and glasses under extreme conditions

We also look at their biological counterparts.

What the group does

The interdisciplinary liquids and complex fluids field has industrial links to:

  • pharmacology and healthcare
  • petroleum and plastics
  • food
  • personal care
  • coatings, formulations, paints and inks
  • agrochemicals

We use a wide range of analytical, experimental and numerical methods, such as:

  • elasticity and continuum mechanics
  • statistical mechanics and non-equilibrium physics
  • microscopy and particle image velocimetry (PIV)
  • rheology and microrheology
  • scattering (light, x-ray, neutron)
  • numerical methods (e.g. computational fluid dynamics (CFD), particle-based methods and Monte-Carlo methods)

Liquids and complex fluids are poorly addressed in the traditional undergraduate curriculum. We inform postgraduate education, for example, in graduate schools working across disciplines.

We also develop new instrumentation and sophisticated data interpretation tools for work on liquids and complex fluids in UK-supported x-ray and neutron sources.
