The ternary phase diagram for N-[3-lauryloxy-2-hydroxypropyl]-L-arginine L-glutamate (C12HEA-Glu), a new amino acid-type surfactant, /oleic acid (OA)/water system was established. The liquid crystal and gel complex formations between C12HEA-Glu and OA were applied to a preparation of water-in-oil (W/O) emulsions. Stable W/O emulsions containing liquid paraffin (LP) as the oil and a mixture of C...

The droplet interface bilayer (DIB) is a promising technique for assembling lipid membrane-based materials and devices using water droplets in oil, but it has largely been limited to laboratory environments due to its liquid construction. With a vision to transform this lab-based technique into a more-durable embodiment, we investigate the use of a polymer-based organogel to encapsulate DIBs wi...

Monodisperse droplet standards are valuable for calibrating spray diagnostics instrumentation and for investigating the effect of drop diameter on the spray phenomena, such as droplet combustion and droplet-film interaction. There is a growing interest in finer monodisperse droplets. To address this need, a new instrument for generating a wide range of monodisperse droplets is introduced, which...

Liquid flow from a column is nebulised using nitrogen or air to give a plume of fine droplets containing the analyte in solution. The liquid droplets pass into a heated zone where the solvent is removed to leave the dried analyte particle which is subsequently irradiated with light. The amount of light scattered is then measured. Gas flow and temperature can be adjusted to optimise the response...

We present a novel approach for Layer-by-Layer (LbL) polyelectrolyte deposition in a “microfluidic pinball” device. Polyelectrolyte multilayers (PEMs) were coated on oil droplets by guiding them through parallel laminar streams of alternatively charged polyelectrolytes. Conventional LbL process is a time consuming and laborious process [1]. Past microfluidics based LbL approaches add operationa...

Phase separation in a polymer dispersed liquid crystal (PDLC), consisting of a main chain liquid crystal (E7) and polymethyl methacryhte (PMMA), was studied by means of light scattering and optical microscopy. The PMMAm mixture exhibits an upper critical solution temperature (UCST), overlapping with a nematic-isotropic transition of the E7 liquid crystal. Several temperature quenches were under...
