Mapping of quantum dots in atomic scale

Having personally worked in the development of quantum dots for commercial applications for a while, I just thought that the work by Dr. Roy Clarke's group on mapping quantum dots in atomic scale could be a highly interesting approach to develop quantum dots production methodologies with customized properties for unique applications.

Dr. Clarke's group at the University of Michigan seems to be working on mapping quantum dots in atomic scale. They believe that this may be highly relevant in understanding and development of controlled fabrication of quantum dots for desirable properties. Here is the link:

Controlling carbon nanotube growth to determine their behaviour as either semi-conductors or metals

Here is an article about a recent finding by scientists at Purdue University and Honda Research Institute that may help scientists in future on how the electronic properties of carbon nanotubes can possibly be determined during their synthesis.

By observing the formation of nanotubes through TEM, scientists are trying to establish the relationship between the conditions of nanotube growth (such as the size and shape of the nano-catalyst used and the role of the inert carrier gas) and the conductive properties of the nanotubes.
