DESCRIPTION:Conformation of Organic Friction Modifiers under shear - Alex 
 Routh\n\nOrganic Friction Modifiers (OFMs) are small amphiphilic molecules
  commonly added to engine oil formulations. They are known to reduce frict
 ion between moving metal parts. The conventional view is that these molecu
 les operate with the polar headgroup attaching to the metal surface and th
 e alkyl chain extending into solution. This conformation remains unproven 
 and there is no knowledge of the effect of shear on the OFM\n \nTo investi
 gate the conformation of OFMs we have built a tribometer which fits onto n
 eutron reflectivity beamlines. This allows the structure of OFMs to be pro
 bed whilst simultaneously applying a well defined shear.\n \nEvidence is f
 ound for the OFM conformation to be reverse micelles adsorbing onto iron o
 xide surfaces.\n\nJerome Neufeld - Storing CO2 in geological complexities\
 n\nThe geological storage of CO2 remains one of the primary means to deepl
 y decarbonise a wide number of industrial processes.  However\, many reser
 voirs are complex\, with structure on many scales impacting the rates and 
 direction of flow\, and the manner in which the buoyant CO2 is ultimately 
 trapped securely.  This talk will focus on a broad overview of the current
  work in the group\, incorporating models of propagation and trapping in c
 omparison with geological and field data where these theoretical ideas may
  be tested.
