The acetone - chloroform system is the classic textbook example of a negative-pressure azeotrope, i.e. the vapour pressures of the binary mixtures are lower than expected for...

Contrary to the strong electrostatic repulsion between like charged ions, last year the Ludwig group, used IR and NMR spectroscopy combined with computational methods, to reveal...

Supported ionic liquid membranes offer potentially lower-energy alternatives to cryogenic distillation for the separation and isolation of light gas olefins (ethene and propene)...

In earlier SANDALS investigations we have shown that protic ionic liquids (PILs) are nanostructured in the bulk, and how dissolved inorganic salts and small molecule solvents...

Asphaltenes are a complex and problematic fraction of crude oil that can precipitate, alter wettability and stabilise unwanted oil-in-water emulsions. Asphaltenes have a high...

Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. However instead of being composed of a salt, the...

The aim of this proposed work is to complete our study of the behaviour of acetic acid/pyridine mixtures as a functionof composition, in order to fully characterise the changes...

We propose to study the hydration of N-methylacetamide (NMA) at ambient conditions and at two concentrations, namely 1 NMA : 50 H2O and 1 NMA : 15 H2O, by applying the isotopic...

The aim of the proposed experiment is to carry out a series of SANS measurements on chain-grafted silica nanoparticles prepared in our laboratory. In this experiment we plan to...

This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled...

6 days on Nimrod are requested to collect neutron total scattering data of 1M, 2M and 3M solutions of a α,ω-dicarboxylic acid, glutaric acid, and 2-methylimidazole...

Polyions and biogenic polyamine are ubiquitous in many important biochemical functions. We propose here to use neutron reflectivity to investigate their potential to induce and...

The organic salt guanidinium mesylate [Gdm][CH3SO3] is a promising phase change material for thermal energy storage applications. It has melting point Tm = 208 °C, and...

A broad fundamental understanding of the design and properties of ionic liquids underpins their developing and future applications, which include accessing cellulosic polymers...

Neutron reflectometery will be used to provide the vital information about the interaction/conformation of the organophosphonate compound on the lipid structure in the...

Anti-fouling surfaces are a critical requirement for a wide range of biomedical applications, such as medical implants and biosensors. Poly(ethylene glycol) is widely used...

A large number of chemicals are currently obtained by catalytic synthetic processes, but usually in most of these processes the catalyst remains in the reaction medium during...

Solvents are integral part of the world and so many charge transfer processes take place in a solutions. Unfortunately, not much is known about the microstructure of solvents...

A number of polymers that are commonly soluble in water and in alcohol, display a dramatic collapse when 10 molar % of alcohol is added to the polymer/water system. Various...

This project aims to examine the structure of microemulsions formed by water and 1-methyl-3-ethylimidazolium-based ionic liquids with the acetate or octanoate anion. These...
