Fabrication of Polymeric Membranes with Micro and Nano Apertures over Large Areas

Li K., Hernández-Castro J.A., Veres T., National Research Council of Canada, CA

Micro- and nano-porous membranes have a wide range of applications including plasmonics, data storage, and energy devices, as well as biomedical devices. Most of them use Si, SiN, or highly periodic anodic alumina membranes. They [...]

Chemistry: The solution for making high performance SWNT-based materials

Simard B., National Research Council of Canada, CA

We explore the chemistry of reduced SWNT and show that it is more advantegous than the chemistry of neutral SWNT. In particular we will show a novel and cost saving functionalization procedureand how it leads [...]

Ab Initio Molecular Dynamics Study of the Pressure Induced Phase Transformations in Cristobalite

Klug D.D., Rousseau R., Uehara K., Bernasconi M., Tse J.S., National Research Council of Canada, CA

The mechanism for the pressure induced transformation of cristobalite to stishovite and post-stishovite phases has been obtained from constant pressure ab initio molecular dynamics simulations. The cristobalite to stishovite transformation is found to be a [...]

Phase Stability and Thermoelectric Properties of Alkali-Metal Doped Group IV Clathrate Compounds

Rousseau R., Toderov E., Uehara K., Tse J.S., National Research Council of Canada, CA

The relationship between phase stability and structure of alkali metal doped clathrate compounds of C, Si and Ge is investigated by a combination of first principles band structure calculations and qualitative tight binding theory. The [...]
