The use of self-assembled nanoparticles for drug delivery has received significant attention in recent years. However, the dynamic nature polymeric systems means there is a need to develop greater understanding inherent stability these systems. In particular, if materials remain as discrete nanoparticles, or exchange material between particles critical. Herein, we labelled pH-responsive with fl...

The formation of gas hydrates is a major issue during the operation oil and pipelines, because cause plugging, thereby disrupting normal flows. A solution to inject hydrate inhibitors such as ionic liquids. Contrary classical inhibitors, liquids act both thermodynamic anti-agglomerates. Imidazolium-based have been found efficient for inhibition CO2 CH4 hydrates. For hydrates, N-ethyl-N-methylmo...
