SANS study of the structure of surfactant stabilised Pt and Ru nanoparticles
Surfactants have been used to bind and disperse Pt and Ru nanoparticles during their synthesis. In this work, we propose to use SANS to determine the thickness and packing... -
Fate of silver nanoparticles in enhanced wastewater treatment
Building on the success of our earlier work, we now propose to use SANS to examine the floc structure and sedimentation behaviour of silver nanoparticles in wastewater matrices... -
Understanding the mechanism of benzyl alcohol oxidation using supported Au-Pd...
This proposal is a continuation of RB1000003. The aim of the present experiment is to gain further insight into the mechanism of benzyl alcohol oxidation using supported Au-Pd... -
Small angle neutron scattering experiment of a novel pH and temperature sensi...
The aim of the present study is to investigate the effect of different stimuli on a novel iron oxide core shell nanoparticles. The system is composed of a magnetite core with a... -
Lipid mesophase alignment induced by nanoparticles: Mesophase determination a...
At a recent experiment at the ILL using D22, we made an incidental observation that addition of hydrophilic silica (SiO2) nanoparticles (NP; D~14 nm) induced alignment in the... -
Inelastic Neutron Scattering Investigations of Hydration Layers on Cobalt Oxi...
We propose to collect INS data with TOSCA on nanoparticles of CoO and Co3O4 with different levels of hydration and size to study the effect of these parameters on the heat... -
Neutron reflection from nanoparticles interacting with insoluble monolayers
Cell-nanoparticle interactions are complex, involving several specific and non-specific intermolecular forces between a wide range of particulate and molecular species . There... -
Structure and formation of L3 phase surfactant templated inorganic oxides
The L3 (sponge) surfactant phase is a promising template for inorganic materials since it is composed of large, uniform water-filled pores separated by a surfactant bilayer. If... -
Proton dynamics of graphenes of different hydrogen content
Graphene is defined as a: single layer of carbon atoms with each atom bound to three neighbours in a honeycomb structure. This suggests that in a macroscopic, manageable... -
INS studies with MAPS of Nafion and model compounds
In the archetypal hydrogenoxygen proton exchange membrane fuel cell design, a proton-conducting polymer membrane (typically Nafion) contains the electrolyte solution that... -
Local structure of polymers in confined geometries in surface dominated samples
This proposal is focused on developing an understanding of how surfaces affect the local structure of synthetic polymers. There is considerable evidence for a strong variation... -
Probing the Kinetics of Assembly and Triggered Dispersion of Peptide-Function...
Peptide-functionalized nanoparticle (NP) aggregates have significant potential as biosensors (for specific enzymes) due to their high sensitivity, modular design and simple... -
Mesophase transition induced by nanoparticles
In a previous SAXS experiment at Max-Lab (Sweden) we observed that the thermotropic mesophase transitional behaviour of the monoolein(MO):cholesterol:water system was... -

In the last few years functionalised carbon nanotubes and carbon nanofibers have shown promising results in the area of heterogeneous catalysis due to the ability to tune the... -
Investigation of the ligand interaction in thiol-capped Au and Pd nanoparticl...
Organic stabilisers, such as thiols, thioethers, amines and polymers (i.e. polyvinylalcohol) have been used for the stabilisation of metal nanoparticles. The catalytic... -
Polymer layer structure in stabilised metal nanoparticles for heterogenous ca...
The controlled synthesis of precious metal nanoparticles of the appriopriate chemical composition, optimised size and morphology for use in catalysis is an ongoing experimental... -
Dynamics of Polymer/Polymer nanocomposites
By adding only about 1% of soft polymer nanoparticles to natural rubber, a dramatic decrease in the viscosity (more than 50%) is induced. Our recent time of flight measurements... -
