Towards a library of functional block copolymers : synthesis and colloidal properties
Understanding the principles of self-organisation exhibited by block copolymers requires the combination of synthetic and physicochemical knowledge. The ability to synthesise block copolymers with desired architecture facilitates the ability to manipulate their aggregation behaviour, thus providing …

Colloidal properties of sugar particle dispersions in food oils with relevance to chocolate processing
The influence of oil-soluble surface-active components on the interactions between fine sugar particles dispersed in different triglyceride oils has been investigated at a range of volume fractions. Four techniques were applied: rheology. sedimentation, light microscopy and adsorption. Eight …

Investigation of the Colloidal Properties of Extracellular Vesicles from Yeast and Bacteria: Implications for Environmental Transport
… Extracellular vesicles (EVs) are nanoscale, colloidal particles that are secreted by all cell types. While the functions of EVs have been investigated in a variety of environmental contexts, including nutrient scavenging, immune responses, and genetic material delivery, the exact mechanisms …

Understanding the Role of Anisotropy on the Optoelectronic and Colloidal Properties of Quantum Rods for Programmable Self-Assembly with DNA Origami
… quantum rods (QRs), have tunable optoelectronic properties that depend on their composition, size and asymmetry. A small change in size or aspect ratio can lead to measurable changes in optical absorption and photoluminescence emission energies, as well as varied degrees of polarized optical …
