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.
The 12th annual BP-Schlumberger Masterclass in Energy Supply and Demand will take place at the BP Institute from 5-6 December 2016. Students with an interest in the future of energy technology or a career in the energy sector are encouraged to apply for this sponsored course.
The Masterclass is now fully subscribed.
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.
We make micron sized water core droplets surrounded by a polymer shell and then place a silver layer around the entire droplet to seal it. The capsules can be used to deliver pharmaceuticals and other small molecules to desired locations.
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.
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.
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.
Migration of CO2 through storage reservoirs can be monitored using time lapse seismic reflection surveys. At the Sleipner Field, injected CO2 is distributed throughout nine layers within the reservoir. These layers are too thin to be seismically resolvable by direct measurement of the separation between reflections from the top and bottom of each layer. Here we develop and apply an inverse method for measuring thickness changes of the shallowest layer.
Physiosorption of large molecules onto surfaces has been an area of longstanding interest for the Clarke group. Simple Van der Waals forces act to keep the molecules attached to the surface, while a variety of intermolecular interactions can lead to spontaneous self-assembly in the plane parallel to the surface. Confinement to two dimensions leads to novel phase behaviour, as well as allowing intermolecular interactions to be more easily characterised.
