Cracking processes in Barre granite: fracture process zones and crack coalescence
This paper presents a comprehensive study of the cracking and coalescence behavior of granite specimens with pre-existing flaw pairs. Uniaxial compressions tests were conducted on Barre granite withExpand
Control of pore size and structure of tissue engineering scaffolds produced by supercritical fluid processing.
This study has demonstrated that the pore size and structure of the supercritical PDLLA and PLGA scaffolds can be tailored by careful control of processing conditions. Expand
Surface-reflection elimination in polarization imaging of superficial tissue.
A method is demonstrated that combines images obtained with linearly and circularly polarized light to produce a polarization-gated image that is free from surface reflections and does not require optically flat plates or matching fluid. Expand
Highly sensitive optical fibre long period grating biosensor anchored with silica core gold shell nanoparticles.
An optical fibre long period grating (LPG), modified with a coating of silica core gold shell (SiO2:Au) nanoparticles (NPs) deposited using the layer-by-layer method, was employed for the developmentExpand
Ultrasound modulated imaging of luminescence generated within a scattering medium
Experimental results show that ultrasound modulated luminescent imaging can resolve two chemiluminescent objects separated by 5 mm at a 7 mm depth within a tissue phantom with a scattering coefficient of 30  cm−1, and Monte Carlo simulations indicate that, with the current system signal to noise ratio, it is feasible to apply the approach to bioluminescence imaging when the concentration of bacteria in the animal organ is above 3.4×105/μL.

Highly sensitive label-free antibody detection using a long period fibre grating sensor
Abstract An optical fibre long period grating (LPG) biosensor is appealing in the detection of biomolecules because of the high sensitivity, label-free and real-time measurement. The miniaturizedExpand
Magnetic Resonance Imaging Analysis of Molecular Mobility during Dissolution of Poly(vinyl alcohol) in Water
Magnetic resonance imaging is used to study changing microstructure and molecular motion during dissolution of poly(vinyl alcohol) (PVA) in water. One-dimensional water concentration profiles wereExpand
Self-diffusion and molecular mobility in PVA-based dissolution-controlled systems for drug delivery.
Nuclear magnetic resonance microscopy has been used to monitor the hydration of poly(vinyl alcohol) (PVA) samples of varying molecular weight, providing supporting evidence for the hypothesis that phenomena such as reptation are important near the glassy/rubbery interface of polymers during dissolution.

Controlling the phase response of a diffusive wave phased array system.
It is demonstrated that controlling the relative phase between the sources enables different phase gradients to be set within the medium, so that the phase response is dependent on the size of an object whilst still maintaining localization information. Expand
