    Neutron reflectometry of quaternary gemini surfactants as a function of alkyl chain length: anomalies arising from ion association and premicellar aggregation. by Li, P, Dong, C, Thomas, R, Penfold, J, Wang, Y

    Published 2011
    “…The structures of the surface layers, which were determined by neutron reflectometry, indicate that the anomalous behavior of the surface tension and area are probably caused by poor packing of the gemini side chains between adjacent molecules. …”

    Interaction of a Cationic Gemini Surfactant with DNA and with Sodium Poly(styrene sulphonate) at the Air/Water Interface: A Neutron Reflectometry Study (dagger). by Vongsetskul, T, Taylor, D, Zhang, J, Li, P, Thomas, R, Penfold, J

    Published 2009
    “…The interactions between a dicationic gemini surfactant with a six-hydrocarbon spacer (1,2-bis(dodecyldimethylammonio)hexane dibromide, C(12)C(6)C(12)Br(2)) and anionic polyelectrolyte DNA or sodium(polystyrene sulfonate) (NaPSS) at the air/solution interface have been studied and compared using neutron reflectometry together with surface tension. In the presence of the dichained cationic gemini surfactant, DNA and NaPSS display very different adsorption behaviors. …”

    Experimental study of surface segregation and wetting in films of a partially miscible polymer blend by Geoghegan, M, Jones, R, Sivia, D, Penfold, J, Clough, A

    Published 1996
    “…We have studied composition-depth profiles in thin films of blends of deuterated polystyrene and poly(α-methyl styrene) using neutron reflectometry and 3He nuclear reaction analysis. Some of the neutron reflectometry data are analyzed using a maximum entropy technique with Bayesian probability. …”

    ORGANIZATION OF POLY(ETHYLENE OXIDE) MONOLAYERS AT THE AIR-WATER-INTERFACE by Henderson, J, Richards, R, Penfold, J, Thomas, R, Lu, J

    Published 1993
    “…Poly(ethylene oxide) has been spread at the air-water interface and the organization of the layer investigated using surface pressure isotherms and neutron reflectometry. Surface pressure data lead to the conclusion that the spread polymer is i a thermodynamically favorable environment on pure water which becomes worse as magnesium sulfate is added to the aqueous subphase.Neutron reflectometry data have been analyzed using both optical matrix and kinematic approximation methods. …”
