Experts Workshop on Metal Hydrides in Biology (Feb 7, 2012)
Dr. Lance Seefeldt will be co-hosting meeting in March at Oxford University.
Peculiar Transformations (Feb 7, 2012)
Alexander S. Ivanov and Alexander I. Boldyrev in collaboration with Peoples' Friendship University of Russia published an article in J.
Chem. Theory Comput. The authors showed that that the transition in
the CxHxP4-x (x = 0-4) series from a three-dimensional tetrahedron-like structure to a planar structure occurs at x = 3, where planar isomers become much more stable than the tetrahedral structures due to significantly stronger ? bonds between carbon atoms in addition to increasing strain energy at the carbon atom in the tetrahedral environment.
Electronic Transmutation (Feb 7, 2012)
Jared K. Olson and Alexander I. Boldyrev introduce a concept of electronic transmutation in their Chem. Phys. Lett. paper. The USU researchers show that boron, by acquiring an extra electron in boron–hydrogen compounds, forms molecular analogs of saturated hydrocarbons. The authors believe that this concept may have a significant effect on predicting new chemical compounds
Studies of the three body problem (Jan 25, 2012)
Studies of the three body problem and, in particular, the Sun–Earth–Moon system, have stimulated an enormous number of advances in physics and mathematics, including the discovery of classical chaos. In this paper a microscopic analogy of the Sun-Earth-Moon system is studied -- the ionization of Rydberg atoms in microwave fields. A remarkable feature of this system is that the electron can follow highly erratic orbits before ionizing.
A comprehensive study of relevant invariant objects in phase is carried out for different system parameters. The consequences of our findings for ongoing experimental studies of the ionization of an electron by the external field are also discussed.
Photoinduced oxidative carbon-carbon bond cleavage (Dec 23, 2011)
Turn on the litght: Photoinduced oxidative carbon-carbon bond cleavage.
Caleb Allpress and Lisa M. Berreau have identified that NiII complexes containing a 2-chloro-1,3-diketonate ligand undergo oxidative cleavage to produce carboxylic acids upon irradiation with UV light under aerobic conditions.
Light-induced oxidative bond (Aug 15, 2011)
Light-induced oxidative bond cleavage reactivity
Katarzyna Grubel and Lisa M. Berreau, working with collaborators at Clemson University and the University of Utah, have discovered novel photo-induced reactivity in metal-coordinated flavonols, which leads to carbon-carbon bond cleavage and CO release under mild conditions. This work has implications toward understanding the influence of metals on the chemistry of flavonols in nature.
