A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each ....A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each other or adhere to surfaces. The knowledge gained in this project will enable improvements to be made in the efficiency of processes such as those listed above.Read moreRead less

Summary
A Pico-Newton Scale Force Measurement Apparatus for Polymer Physics and Non-equilibrium Statistical Mechanics. We propose to build a state-of-the-art Optical Tweezers apparatus that measures small forces and torques on micron-sized objects located in 'optical traps'. Using a single laser beam and computer-generated holograms, we will create arrays of optical traps that move or 'dance', and alter the force/torque-imposing properties of each trap. This proposed research equipment will be used (1 ....A Pico-Newton Scale Force Measurement Apparatus for Polymer Physics and Non-equilibrium Statistical Mechanics. We propose to build a state-of-the-art Optical Tweezers apparatus that measures small forces and torques on micron-sized objects located in 'optical traps'. Using a single laser beam and computer-generated holograms, we will create arrays of optical traps that move or 'dance', and alter the force/torque-imposing properties of each trap. This proposed research equipment will be used (1) to study the physics of single synthetic polymer and naturally occuring biopolymer chains, (2) to quantify experimentally, and for the first time, newly predicted molecular-scale forces, and (3) to demonstrate new theories in non-equilibrium statistical mechanics that quantitatively describe the operation of nanomachines.

Adaptive optical devices by microstructuring of nanocomposite materials. This project will develop novel nanocomposite materials and use them to fabricate adaptive optical devices designed and fabricated using innovative methods. Specifically, we will develop and characterise transparent composite materials comprising a dispersion of nano-sized inclusions within a polymer host. The properties of these materials will be tailored to allow fabrication of adaptive optical devices (e.g. tunable filte ....Adaptive optical devices by microstructuring of nanocomposite materials. This project will develop novel nanocomposite materials and use them to fabricate adaptive optical devices designed and fabricated using innovative methods. Specifically, we will develop and characterise transparent composite materials comprising a dispersion of nano-sized inclusions within a polymer host. The properties of these materials will be tailored to allow fabrication of adaptive optical devices (e.g. tunable filters and optical switches), which will be key components in future high-performance optical systems. Inverse scattering design methods will be extended to design two-dimensional bandgap devices which will be fabricated by microstructuring of the composite polymer materials.Read moreRead less

This proposal offers the opportunity to make major advances in this dynamic new area, not only changing the fibre properties by means of its microstructured but also by its material properties. The proposed research will enable us to fabricate new types of optical fibre by exploiting three completely different technologies: polymer materials, microstructured polymer fibres (mPOF) and nanoparticles. This project will build on our existing success in developing mPOF, and create major new opportunities, both in fundamental science and in applications that could and would be commercialised.Read moreRead less

We propose a combined experimental and theoretical investigation of single polymer chains, exploring how their shape or conformation, and stretching characteristics are affected by specific molecular interactions. Our tools in this study are both experimental and theoretical: optical tweezers, atomic force microscopy, as well as new theories in colloid science, and computer simulation. In particular, we will examine the effect of different salts and sugars upon the properties of polymers such as DNA, and how monomer sequence can lead to dramatically different structures in solution which in turn will lead to novel materials.Read moreRead less
