Michael Berger’s Nov. 7, 2012 Nanowerk Spotlight article about nanoporous adsorbents and protection against toxic nerve agents features Dr. Piotr Kowalczyk, a Senior Research Fellow at the Nanochemistry Research Institute at Curtin University of Technology in Australia, quoting English theoretical physicist, Paul Dirac,
“Some of my colleagues asked me if I believe in our theoretical results” says Kowalczyk. “The great physicist Paul Dirac used to say: ‘This result is too beautiful to be false; it is more important to have beauty in one’s equations than to have them fit experiment’.”
“And I truly believe that our theoretical results have to be correct – within the assumed model of nanopores – because they are so simple and beautiful” he concludes.
Kowalczyk is discussing some of his latest work on protection against toxic nerve agents (Note: I have removed a link),
In a paper published in the October 31, 2012 online edition of Physical Chemistry Chemical Physics (“Screening of Carbonaceous Nanoporous Materials for Capture of Nerve Agents”), an international team led by Kowalczyk and Alexander V Neimark, a professor at Rutgers University, together with scientists from the Physicochemistry of Carbon Materials Research Group at Nicolaus Copernicus University in Poland, is shedding new light on the selection of an optimal nanomaterial for capturing highly volatile nerve agents.
Berger’s article gives some context for this research,
Protection against nerve agents – such as tabun, sarin, soman, VX, and others – is a major terrorism concern of security experts. Nerve agents, which attack the nervous system of the human body, are clear and colorless or slightly colored liquids and may have no odor or a faint, sweetish smell. They evaporate at various rates and are denser than air. Current methods to detect nerve agents include surface acoustic wave sensors; conducting polymer arrays; vector machines; and the most simple: color change paper sensors. Most of these systems have have certain limitations including low sensitivity and slow response times.
