Design & Operation of Wind Farm Support Vessels 2019.
The latest technology in local position reference sensing is changing the way that vessels operate alongside assets, whether that be an oil platform, another vessel or an off-shore wind turbine. These technologies allow local positioning to be comple

We have investigated a novel method of remotely switching the conformation of a weak polybase brush using an applied voltage. Surface-grafted polyelectrolyte brushes exhibit rich responsive behavior and show great promise as "smart surfaces", but exi

Thin films of polymer mixtures made by spin-coating can phase separate in two ways: by forming lateral domains, or by separating into distinct layers. The latter situation (self-stratification or vertical phase separation) could be advantageous in a

Neutron reflectivity and photoluminescence measurements are reported on bilayers of polyfluorene-based conjugated polymers. By using a novel thermal processing procedure it is possible to control the width of the interface between poly(9,9-dioctylflu

Thiol encapsulated gold nanoparticles can be used as sensitive probes of gas and vapour concentrations. The conductivity of a thin film of two or more layers of such nanoparticle arrays can be measured using interdigitated gold electrodes. The conduc

Langmuir films of gold nanoparticles functionalized by 4-methylbenzenethiol on a water subphase were studied. Multilayers on Si and glass substrates were successfully fabricated by both the Langmuir–Blodgett (LB) and Langmuir–Schaefer (LS) deposi

The properties of 4-methylbenzenethiol capped gold nanoparticles have been investigated at the air–water interface. Langmuir isotherms and compression cycles show that a stable monolayer is formed on the water surface. In situ UV-visible spectrosco

Spin-coating is a very widely used technique for making uniform thin polymer films. For example, the active layers in most experimental semiconducting polymer-based devices, such as light-emitting diodes and photovoltaics, are made this way. The effi

Thin films of 5 nm gold colloid nanoparticles were deposited onto solid substrates (silicon, glass, gold coated glass) by the Langmuir-Schaeffer (LS) method at a surface pressure of 10 mN/m. The films produced were characterised with optical techniqu

We have studied the Forster transfer dynamics in spin-cast polyfluorene blends and Langmuir–Blodgett (LB) nanostructures by time-resolved photoluminescence (PL) spectroscopy. The blend system consisted of poly(9,9-dioctylfluorene) (F8) as the host
