Topological insulators (TIs) are quantum materials with insulating bulk and topologically protected metallic surfaces with Dirac-like band structure. The most challenging problem faced by current investigations of these materials is to establish the existence of significant bulk conduction. Here we show how the band structure of topological insulators can be engineered by molecular beam epitaxy...
High-throughput few-layered BN nanosheets have been synthesized through a facile chemical blowing route. They possess large lateral dimensions and high surface area, which are beneficial to fabricate effectively reinforced polymeric composites. The demonstrated composites made of polymethyl methacrylate and BN nanosheets revealed excellent thermal stability, 2.5-fold improved dielectric constan...
The effectiveness of various insulating materials for limiting radon entry into houses has been investigated under laboratory conditions. Results for the radon diffusion coefficient measurements in more than 80 insulating materials are summarized. We have discovered that great differences exist in diffusion properties, because the diffusion coefficient varies within four orders from 10(-13) m2/...
The onset of Marangoni convection for evaporating liquids Brendan D. MacDonald Doctor of Philosophy Graduate Department of Mechanical and Industrial Engineering University of Toronto 2012 The stability of evaporating liquids is examined. The geometries investigated are semiinfinite liquid sheets, bounded liquid sheets, sessile droplets, and funnels. Stability parameters are generated to charact...
