What the students looked at - Hydrogen atom wave functions.
BEST for LAST
The electronic density of the hydrogen atom has been extensively used in classes but I will come full circle with
its impact on my research.
There are a whole page of these on Meital's site at
But this is only the beginning.
Once we had the technique developed, it turned out useful for a research problem,
measuring the width of a nanotube - a parameter we needed to model
nanotube vibrations. If you can measure these then you can weigh molecules such as DNA by seeing how the vibrations change.
We have proof of concept from simulations and Yuval Yaish has measured this in the lab.
I show this for the unencumbered nanotube below left, show the nanotube with an attached ring center left below, the larger nanotube electron density center right below and below right Sharon Maliniak's
calculation of the density with ring attached.
The left image is from a paper by a student intern Bastien Grosso in Computer Physics Communications
and the right visualization is from a student course project by Sharon Maliniak, with data from Omri Adler, my last MSc student. Sharon while joining a group discussion when she was doing another project with me suggested better adhesion with larger nanotubes, then took my class and got the visualization as a project. Another example of education/research interaction!
