    I met Harry a few years ago at my university. My research group had a meeting with him and he was such an interesting and approachable guy. Really into his science and such an advocate for science education. Shame to have lost someone so enthusiastic and driven.

    Greetings Sir Martyn Poliakoff! You are absolutely right about how humble Dr. Kroto was. I had the opportunity of listening to his keynote presentation at the American Chemical Society a year or two before he passed away, in Tennessee. Later on in the same day of that presentation, I saw Dr. Kroto at a bar from the conference hotel and I mentioned to him about how nice and inspiring his presentation was. He asked me to sit down next to him and tell him about my research. He made me feel very welcomed and important. I talk to my students in General Chemistry on how I met him, how he was very humble, and of his impressive discovery of the carbon allotrope. When I watched your video, it made me sad because such a wonderful and passionate educator died. But I am happy you made the video as an amazing tribute to him. I’m sorry you lost your friend. Big hug. Sincerely, Edward D’Antonio

    Not enough scientists advocate the importance of teaching science to others. R.I.P a great scientist that had such a big impact on the scientific community.

    • @VeteranVandal
      @VeteranVandal 8 лет назад +2

      Yes, that is indeed sad. In fact most of us (scientists) hold the belief that the student has to prove they are worth an explanation before having it given.
      I don't agree with such approach, because to me it seems like answering your question by yourself instead of encouraging collaboration or asking question.
      This is an old academic problem, but I can only hope we are going gradually in the right direction.

    I can confirm Harry was a very kind, modest man. Quite remarkable for a Nobel Prize winner. I met him once as a first year postdoc at a conference dinner. He wanted to sit at a table with students, and my friend and I were the youngest in the group, so he chose our table. He was delightful to talk to and very interested in our projects. Being in a different field, I didn’t know who he was or how famous he was. Upon leaving the dinner, one of the Conference organizers came up to me and said “What was it like eating with a Nobel Laureate?” I can say it was a truly lovely experience getting to meet Harry. This was a lovely video tribute to him and C60.

    I went to the same secondary school as Harry Kroto did (though not until many years after he had left) and I started my A-levels (including chemistry) in 1997, the year after he won his Nobel Prize. It was always something of an inspiration to me back then to think that maybe I was learning science in one of the same rooms that he had learned in, years earlier.

  • @EebstertheGreat
    @EebstertheGreat 8 лет назад +1

    Perhaps in response to this upload, the relevant article has shot to the top of google search results for "C60La," but unfortunately it is very expensive and even the preview image does not exist. Does anyone know why the inclusion of a lanthanum atom would make the structure more plausible?

    • @EebstertheGreat
      @EebstertheGreat 8 лет назад

      TheNuklearAge But C60 is (partially) aromatic, right? The usual description is that every bond has bond number 1.33, so every carbon atom participates in 4 bonds. There is dihedral strain obviously, but the dihedrals are around ±140°, so it's not that bad.

    • @TheNuklearAge
      @TheNuklearAge 8 лет назад

      EebstertheGreat
      Hybridization works well for simple cases but is not generally used for fullerenes as the descriptor is controversial, but even from that perspective not all carbons would have 4 bonds. Coordination-wise it is 3.
      Quantum calculations do indeed show that C60 has less binding energy than graphite but more than its neighbors, that is, it's a local minimum not a global. It's well known , though, that diamond is also metastable by this definition.

    • @EebstertheGreat
      @EebstertheGreat 8 лет назад +1

      TheNuklearAge Sure, well it's not surprising that it is a higher energy configuration than graphite, since that is the stable allotrope of carbon. But what exactly do you mean that "coordination-wise" there are only 3 bonds? Is it because the other electrons are delocalized?
      I don't really know anything about fullerene chemistry, but my understanding was that the delocalized electrons were stabilizing rather than destabilizing like they are in planar aromatic compounds.

    • @EebstertheGreat
      @EebstertheGreat 8 лет назад

      TheNuklearAge You don't need that kind of precision when describing the structure of organic molecules. Molecular orbital assignment for small molecules is generally pretty straightforward with modern quantum dynamics suites, assuming accurate empirical parameters are available. There is no reason you would want to calculate everything _ab initio_. I've worked with energy minimization and solvation of ~40 atom aromatic molecules before on Gaussian without much difficulty, and that was using just 4 CPUs for an hour at a time. Of course you don't use the complete Schrodinger equation, you use a self-consistent field equation.
      Looking online, I found a value for the pentagon-hexagon bond cited as 1.17 and for the hexagon-hexagon bond cited as 1.37, implying each atom participates in ~3.5 bonds, which I admit is somewhat unusual.

    • @EebstertheGreat
      @EebstertheGreat 8 лет назад

      TheNuklearAge The only DFT I've used was B3LYP, which I used extensively for geometry optimization in substituted amino acids, but I'm not sure it would be adequate for fullerenes. But I think I have a different idea of "big calculations" than you do, since most of my work was in protein minimization, where a very "small" _classical_ calculation had something like 1500 atoms; the DFT was just for generating parameter files.

    I remember reading a short pop-sci article about C60 in early 1990s. Back then, it was speculated, that such big, enclosed molecule could be used as a container, either to deliver some chemicals or drugs or to contain some pollution. Seems to me, C60 was never as hyped as graphene or nanotubes are now, so I wonder, what came out of it, have there been found any applications for it?

    Wonder if it is possible to set up a carbon 60 sensor or collector on a spacecraft and put that in orbit around the sun to further this field of study. We couldn't put a spacecraft around another star but maybe it's possible to get enough information by studying our own sun that we could estimate the production rate of C60 by other stars.
