The Nanoscience facility is located on the second floor of the Summerlee Science Complex in rooms 2109 and 2110. These laboratories provide undergraduate students a unique opportunity to study the chemical and physical behaviour of materials at the nanoscale. Specialized laboratory experiments have been developed to give our undergraduate students a unique hands-on laboratory experience in which students learn to prepare a variety of nanomaterials and measure their properties using state of the art imaging and spectroscopic instruments. The Nanoscience courses are taught by members of the physics and chemistry departments that provides our students with multidisciplinary training that prepares them for their future careers in academia or industry.
Atomic force, electron and optical microscopy techniques
Interractions of electromagnetic waves with various materials
In dynamic light scattering (DLS), the diffusion of colloidal particles, with diameters ranging from 0.006 to 6 , suspended in aqueous media is measured that allows the determination of the particle radius (hydrodynamic radius) and polydispersity. The zeta potential can also be measured, which is a measure of the surface potential of charged colloidal particles. Colloids with a high surface potential will remain stable in solution while low surface potential species tend to flocculate or coagulate.
Physical measurements of the properties of nanostructured surfaces
Spin Coating - We use spin coating to deposit uniform, thin films of polymers, e.g., polystyrene, polyethylene, photoresists, onto a variety of substrates by varying the concentration of polymer solutions (several percent by mass) and the spin speed of the substrates (500 - 5000 rpm).
