Dynamic and static light-scattering goniometer for soft nanocomposites

点击翻译按钮获取中文摘要

Requested is a state-of-the-art dynamic and static light-scattering goniometer for studying soft condensed matter, particularly polymer solutions, colloidal dispersions, nano-emulsions, and hydrogels. The instrument detects the light scattered from these materials, furnishing fundamental quantitative measures of their nano-scale dynamics and structure. These data will be used to (i) test synthetic protocols, providing the size of macromolecules and nanostructures in solution; (ii) assess material performance and function, including the degree to which nanoparticle dynamics couple to polymeric networks; and (iii) interpret novel diagnostic testing platforms for nanomaterials research, including the application of electroacoustic spectroscopy and dielectric spectroscopy for hydrogel nanocomposites and nanoemulsions. The instrument will be the first of its kind in Canada, supporting a research program that is developing hydrogel-nanocomposites for Canada's advanced-materials sector, and seeking fundamental knowledge to enhance health, environmental, and energy applications of nanotechnology. Training of highly-qualified-personnel will bring expertise in nanoscience and state-of-the-art light-scattering technology to Canada's industrial and academic research laboratories. Fundamental knowledge on the dynamics of nanoparticles in hydrogels will provide scientific guidance for industrial and governmental regulatory bodies on nanoparticle release and toxicity.**
