Electrochemically Growing Hydrogels to Control Stiffness
At high pH many low molecular weight gelators (LMWG) are dispersed in solution. When a trigger is applied to lower the pH the gelator molecules self-assemble into one... -
Understanding the network change in reversible photochromic hydrogels
Photochromic devices are ones which change colour upon the irradiation of light. These devices can be used a sensors, logic gates and privacy windows etc. Here we show and... -
SANS from photoconductive hydrogel mixtures and their gelators.
Hydrogels are formed from a self?assembled network of fibres made up of small molecules (gelators) trap and hold water at just 1% by weight, or less, from the solution they are... -
Rheo-SANS study of peptide gels
Low molecular weight gelators (LMWG) form hydrogels via self-assembly in water under specific conditions to form long, fibrillar structures. Non-covalent forces interactions... -
Rheo-SANS of 2NapFF
We are investigating a range of functionalised dipeptides. For some examples, anisotropic structures are formed in water at high pH, which can be gelled by addition of a calcium... -
Hydration effects in gels for water splitting.
Storing the energy available from the sun as a fuel that can be used anytime is a major global challenge. Organic materials synthesised from abundant elements that can harness... -

The effect of heating on Gelator Solutions
Low molecular weight gels are formed by the self-assembly of small molecules into fibres that entangle to form a matrix. Hydrogels are an important class, as these are typically... -
The effect of hydrophobic additives on low molecular weight gels
Low molecular weight gels are the result of the self-assembly of small molecules into fibres. These entangle to entrap the solvent. When the solvent is water, these are called... -
Investigation of the micellar aggregates in low molecular weight gelators
We have been investigating dipeptide-based low molecular weight gelators. Here, on lowering the pH from 12 to 4, a self-supporting gel is formed. Gels are formed by the... -
Can SANS confirm whether dimensions from microscopy of dried gels are represe...
Characterisation of structures formed within hydrogels is an important part of understanding their properties and how they can be used in real world applications. The real space... -
Using contrast matching to understand the networks in multicomponent systems
We have been focusing on two component gel networks. Here, both components can individually form gels. In a mixed system, the LMWG can either co-assemble or self-sort. In a... -
Contrast variation studies of novel binary polypeptide gels
Low molecular weight gelators (LMWG) form hydrogels via self-assembly in water under specific conditions to form long, fibrillar structures. Non-covalent forces interactions... -

In situ SANS of Electrochemically Formed Gels
Gels can be formed by the self-assembly of low molecular weight gelators. These molecules self-assemble into fibres, which entangle to form the matrix of the gel. Most methods... -

Elucidating the microstructure of dipeptide-based gelators
Dipeptide-based gelators can form hydrogels at low concentrations using a number of means. We have found that the method by which the gels are formed can have a profound effect... -
SANS from photoconductive hydrogel mixtures and their gelators.
Hydrogels are formed from a self?assembled network of fibres made up of small molecules (gelators) trap and hold water at just 1% by weight, or less, from the solution they are... -
Rheo-SANS study of hydrogel mixtures during gelation under shear.
Small molecules known as low molecular weight gelators (LMWG) can self-assemble to form a network of fibres, which trap and hold a vast amount of water forming a gel. An... -
GISANS from photoconductive hydrogel electrodes.
The sun is an abundant and cheap source of energy, harnessing it as storable fuel has the potential for a large societal impact. Organic photoelectrodes (PEs) formed from low...
