About

The Fluids, Particles and Interfaces group at Queen Mary University of London is interested in fundamental aspects of microscale fluid mechanics and transport phenomena in multiphase systems. My name is Lorenzo Botto, and I am leading the group since 2013. 

Much of my group’s research focuses on topics at the interface between classical fluid mechanics and materials science.

These include the mechanisms of formation of solid-stabilised emulsions, liquid transport in oil repellent textiles, and the liquid processing of  nanostructured materials.

Thanks to support from the European Research Council we have initiated an ambitious research line on the hydrodynamics of graphene and other flexible 2D nanomaterials.

The ERC project FlexNanoFlow aims to understand the  dynamics of 2D nanomaterials in sheared liquids, how nanosheets deform, break and orient themselves in complex flows, for applications such as coating, printing, and nanocomposites manufacturing.

My group uses primarily simulation and theory. However our studies often starts from experimental observations. We are building our own experimental lab, and collaborate extensively with experimentalists in the UK and abroad. We collaborate with fluid mechanicians, soft matter physics,  colloids and interface scientists, and materials engineers. 

Current research areas are:

  • graphene hydrodynamics: modelling deformation and dispersion of 2D nanomaterials in sheared liquids
  • fundamentals of dispersed multiphase flows, including drops, particulate suspensions, and powders;
  • modelling of particle-laden drops,  bubbles and emulsions, for applications to materials science (e.g. nanoparticle stabilised polyner blends) and chemical engineering;
  • micromechanics of and solute transport in biological and bioengineered materials, including cell mechanics and transport in gels for regenerative medicine; 
  • capillary deformation of drops on deformable substrates (“soft wetting”);
  • fluidisation of pharmaceutical drug powders in inhaler devices;
  • liquid transport in textiles via X-ray microscopy.

The Fluids, Particles and Interfaces research group is embedded into the wider QMUL’s Fluid Group.
