Shape- and depletant- induced assembly of nanocolloids in submicron channels
Understanding the behavior of colloidal nanoparticles in submicron channels is essential for a number of technological challenges including fracture healing, channel-transport... -
Elucidating buried structures using Offspec
This proposal is a continuation proposal (previous RB 1110285) utilising the Offspec instrument and is aimed at further understanding the utility of the spin echo grazing... -
Depth profiling fullerene-free organic solar cell blends using neutron reflec...
In Sheffield, 9% efficient organic solar cells have been made using a new non-fullerene acceptor called ITIC, when blended with semiconducting polymers. GIWAXS measurements have... -
Phase separation in confined polymer blends studied by SERGIS
We intend to study the phase separation morphology of confined polymer blends. Interface forces will impose morphologies different from those in the bulk. In our experiments the... -
Understanding domain organization in a binary lipid mixture by SERGIS
Membranes of cells are the physical barrier between the inside and outside of the cell. Transport and signaling is control by transport and signaling proteins but their ability... -
pH-driven self-assembly of colloidal particles confined between parallel walls
Small particles with dimensions of a few hundred nanometers tend to behave differently when confined in small spaces. Examples of such situations are easy to find in nature --... -
Membrane-stacking properties of myelin proteins
Myelin is the multilamellar structure that ensheaths axons and accelerates nervous impulses in the nervous system. The fine structure of myelin remains to be further... -
Characterization at low Q values of a thermo and pH-sensitive hydrogel
Among soft colloidal systems microgels, aqueous dispersions of nanometer or micrometer-seized hydrogel particles, have been the subject of intense research in the last years... -
Probing binary mixtures of hard spheres
As part of a larger programme we aim to test densely-packed binary mixtures of monodisperse hard sphere powders to determine local structure, to correlate with ratio of... -
Investigation of the microstructure of dipeptide hydrogels
The properties of gels formed from the self-assembly of small molecules depend on the properties of the fibres into which the molecules have assembled as well as the number and... -
Aggregation phenomena inside polymer brushes: lateral structure
We will use off-specular reflectivity to probe the characteristic lateral length-scales in responsive polyelectrolyte brushes grown by surface-initiated ATRP from solid-liquid... -
Competitive interactions in polymer-particle-surfactant blends
Many formulations comprise distinct chemical species that exhibit antagonistic or synergistic interactions that result in unpredictable behaviour. Previous work from our group... -
Measurement of spin-gravity coupling by quantum interference
It is possible that there is a coupling between the spin and gravitation, for instance by an adaptation of the Hamiltonian with an additional termH=k/c (gvec.Svec) where gvec is... -
An off-specular neutron scattering study of the 'peristaltic mode' in the dew...
We plan to use the OFFSPEC SPIN-Echo reflectometer to study the mechanism of the 'peristaltic mode' in the spinodal dewetting of thin polymer films. In the peristaltic mode the...
