Carleton University has various nanotechnology projects, including an award winning idea from a chemistry professor that has the potention to speed up the internet by 100 times through the use of light.

The research also has bearing on on smart "optical" clothing, network security monitors, personal bio-sensors for rapid medical diagnostics, and affordable high-efficient plastic solar cells.

ONE PROJECT
Development of X-ray diffraction for applications to nanophase materials

This is a relatively new area for us in which, as a first step, we are developing algorithms and software programs to simulate the diffraction patterns arising from various model small particle systems having specified particle sizes and shapes, specified varying degrees of atomic positional disorder, specified varying degrees of defects, such as vacancies, specified thermal ellipses of the atoms, specified microstructures involving particle-particle correlations and specified cluster structures, based on various polymerization rules.

Chemistry and Physics of Carbon, Volume 30

Written by distinguished researchers in carbon, the long-running Chemistry and Physics of Carbon series provides a comprehensive and critical overview of carbon in terms of molecular structure, intermolecular relationships, bulk and surface properties, and their behavior in an amazing variety of current and emerging applications, ranging from nanotechnology to environmental remediation. Volume 30 not only retains the high-quality content and reputation of previous volumes, but also complements them with reliable and timely coverage of the latest advances in the field.

The first chapters analyze progressive approaches to controlling more precisely the structure, morphology, and surface properties of novel activated carbons. They cover methods using activating agents such as alkaline hydroxides as well as endo- and exotemplates made from zeolites, silica, and colloidal crystals. The third chapter examines techniques for characterizing carbon surface chemistry, including electrochemical, spectroscopic, and chromatographic methods. The fourth and final chapter compares the virtues of exfoliated graphite, carbonized fir fibers, carbon fiber felt, and charcoals in solving oil spill problems, a matter of increasing environmental concern.

Emphasizing key experimental results, practical aspects, and cutting-edge applications in every chapter, Volume 30 is a vital resource for those developing new technologies such as drug delivery, adsorbents for oil/chemical spills, materials processing, high-performance nanocarbons, and energy storage and conversion devices, including lithium ion batteries, supercapacitors, and fuel cells.
