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 --... -
Exploring the structure of charged colloids in periodic nano-confinements
Experiments have suggested that particles in a colloidal suspension tend to form layers close to confining walls but this conjecture is difficult to prove unambiguously.... -
Testing the efficacy of the spin echo technique combined with the dynamical t...
The sensitivity of the Spin Echo Resolved Grazing Incidence Scattering (SERGIS) to scattering geometry and sample specifications has been tested at OFFSPEC on gratings with... -
Comparison Phase-object approximation and dynamical scattering theory
X-ray, electron and neutron scattering techniques have been used for the structural characterization of surfaces and embedded morphologies. Several theories have been developed... -
Investigating the response of lipid bilayers to physically structured substrates
The functionality of biological membranes is closely tied to their structural behavior. To understand this behavior we propose to study the conformality of artificial lipid... -
A study of model systems to further increase understanding of the limits of c...
Recent developments in the theoretical treatment of SERGIS have significantly advanced our understanding of the capabilities of the technique. Numerous examples of scattering... -
Exploratory SERGIS/SESANS study of Si nanowires
Nanowires are increasingly being used in life science as nanometer probes and interfacing with cells. In our work we focus on the interaction between nanowires and a... -
Structure of Hard Sphere Colloids in Nano-Confinements
In a previous OFFSPEC experiment we showed that when a suspension of 100-nm-diameter, charge-stabilized silica particles suspended in a refractive-index-matched solvent is... -
Exploring colloidal assembly in periodic nano-confinements using neutron spin...
Colloids in confinements have structural and dynamic properties in some cases very different from bulk properties. In particular, when the width of the confinement is few times... -

In a previous OFFSPEC experiment we showed that when a suspension of 100-nm-diameter, charge-stabilized silica particles suspended in a refractive-index-matched solvent is... -
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... -
