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... -
Measurement of gravitation-induced quantum interference
We propose to perform accurate measurements of the quantum gravitational effect for OffSpec. We would like to investigate if a similar discrepancy between quantum system gravity... -
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... -
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... -
Basic Science for Offpsec : Part 2
This proposal is part 2 of a set of two proposals on Offspec aimed at understanding some of the effects seen in off-specular data and in particular the use of the spin echo... -
Phase-object approximation in neutron reflectometry
Recently De Haan et al. described the phase-object approximation for small angle neutron scattering. This method can be extended towards neutron reflectometry. Prelimenary... -
Studying Artificial Ripple Structures
In addition to smoothing and self-affine roughening ion bombardment of solid surfaces can result in ripple and dot structures with nanometer scale dimensions. This method... -
Polymer brush profiles using off-specular reflection from the walls of trenches
Nature frequently uses charged, weak-polyelectrolyte brushes at interfaces to control surface function and properties; surface wetting, lubrication, to limit deposition of... -
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... -
Investigating the Influence of Polymer Properties on Cyclic Peptide-Polymer C...
Cyclic peptides with alternating side chain stereochemistry are capable of self-assembling into long nanotubes (CPNTs). The conjugation of polymers to these peptides renders the... -
Determining the nanostructure of PCBM in thin film photovoltaics
Organic photovoltaics (OPVs) are a low cost alternative to existing photovoltaic materials. The efficiency of OPVs is steadily increasing towards the point where their cost per... -
Tuning the Magnetic Properties of γ-Fe2O3 Fe3O4 Thin Films for Atom Tr...
In this work we will investigate how the magnetic properties of nanometer thick iron-oxide films can be manipulated by heating them in air. Our preliminary results indicate that... -
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... -
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... -
Dataset for Inversion of 1D SAXS grating signal
This simulated dataset consists of 48k train, 6k validation and 6k test data in the h5py file format. A small example on how to access the data is located in the python script...
