The aim is to improve understanding of solution properties and aggregation of hydrotropes and alkyl¿hydrotropes, and the relationship with common surfactants. Although they are...

We request 12 days on TOSCA to study the interaction of adsorbed N2, CO2, CH4 and NO with a hydroxyl-decorated aluminium-based MOF NOTT-300. This proposed study will investigate...

This proposal aims to explore organogel systems, like those recently decsribed1-3, but made from new CO2 philic surfactant-gelators. These have been synthesised to feature...

This proposal aims to explore co-surfactants, as additives with CO2-active surfactants, for elongating reversed micelles in dense CO2 by using high-pressure small-angle neutron...

Recent infrared measurements by one of the applicants (GR) have shown that CO and CO2 adsorption on alumina-supported palladium catalysts form a variety of carbonate species. In...

This proposal aims to investigate and compare the dynamics of CO2 when confined in a nanoporous Vycor (SiO2) matrix. The field of fluids in confined geometries is currently of...

This proposal is to probe the gel structure with High Pressure SANS (HP-SANS) using an in-line pressure cell. The ability to control the properties of supercritical CO2,...

We aim to utilise Low-Energy Neutron Scattering (LENS) at OSIRIS to investigate the effects of gas adsorption on the quantum rotation of the methyl groups present in a Metal...

The combination of NMR, DFT based ab initio molecular dynamics (AIMD) and total neutron scattering aided by EPSR simulations provide a new method for understand the factors...

New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have...

This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is...

This proposal involves manipulating the curvature of aggregated polar materials in supercritical CO2 (scCO2) by tuning the mixing ratio of fluorocarbon (FC) and hydrocarbon (HC)...

In conjunction with an industrial partner (Sasol Technology UK), the applicants have previously used INS measurements performed on the MAPS spectrometer to characterize a series...

The study of porous metal-organic framework (MOF) materials has attracted considerable attention. We seek to develop new stable MOFs for practical separation of light...

The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental...

This proposal aims to study condensation transitions in nanoporous flexible materials by means of wide Q-range neutron diffraction. We plan to perform an in-situ gas...

We request GEM beamtime to study the structure of samples of sodium silicate glass with and without CO3 carbonate groups. The presence of CO3 carbonate groups in the glasses is...

This proposal focuses on a new approach to the formation of rod-like micelles in supercritical CO2 (scCO2). Recent successful high-pressure SANS (HP-SANS) results have shown for...

This proposal involves manipulating the curvature of aggregated polar materials in supercritical CO2 (scCO2) by tuning the mixing ratio of fluorocarbon (FC) and hydrocarbon (HC)...

Small gold nanoparticles (1-5 nm) supported on metal oxides are extremely active catalysts for C-C coupling, aerobic oxidations and selective hydrogenations. The interaction of...
