About the BP Institute

The University of Cambridge BP Institute was established in 2000 by a generous endowment from BP, which has funded faculty positions, support staff and the Institute Building, in perpetuity. The Institute research focuses on fundamental problems in multiphase flow and is highly interdisciplinary, spanning six University Departments.

Casting dispersions

We show how droplets which comprise two solvents of different volatility can display an instability during drying. This can drive suspended solutes to the edge of the droplets and create a non-homogeneous final film.

Investigating adsorption of organic molecules at challenging metal/oil interfaces

Buried interfaces, pertinent to realistic environments such as those found in a car engine, are notoriously difficult to investigate due to the challenges of accessing information concerning the interface itself without being swamped by the much greater signal from the bulk materials; here, we describe the combination of a suite of sophisticated surface study techniques to characterise small molecules adsorbing at key metal surfaces from an oil phase.

Protein behaviour at biomaterial interfaces

adsorption on stainless steel surface

Understanding the structure and behaviour of proteins adsorbing at key biomaterial surfaces is both challenging but also critical to designing implants that interact favourably with the body. Here, we report the first use of the powerful surface analysis technique neutron reflectometry to characterise a stainless steel surface and the adsorption of key proteins found in the blood plasma thereupon.

Sticky Minerals

mica sheet on silicon block support

Figure illustrating the very thin mica sheet on the silicon block support. The Data shows the distinctive ‘double critical angle’ indicative of the mica/D2O interface (the two ‘steps’ at low Q) and the changes on adsorbing a layer of AOT at the mica surface, clearly evidence at high Q. using data such as this we can identify and structurally characterise the layers at the mica surface.
