February 2014      Jiajue Chai turn in his Ph.D. dissertation and is heading off to a postdoc at Brown. Congratulations!.
Also, two manuscripts were submitted this month. One, submitted to the Journal of Physical Chemistry A, combines Jiajue's work on absolute rate constants here ESF with Hongyi's work determing relative rate constants at NCAR. The other manuscript, submitted to the International Journal of Chemical Kinetics is Jiajue's work on the pressure and temperature dependence of the reaction of methoxy radical with NO2.

December 2013      Jiajue Chai passed the defense of his Ph.D. dissertation. Congratulations!.
Also, Hongyi published her paper on Quantum Chemistry, Reaction Kinetics, and Tunneling Effects in the Reaction of Methoxy Radical with O2 in the Journal of Physical Chemistry A.

April 2013      Hongyi Hu passed the defense of her Ph.D. dissertation. She was also awarded the department's Michael M. Szwarc Award in Physical Chemistry. Congratulations!.

January 2013      Yuan Sha passed the defense of her M.S. thesis. Congratulations!.

December 2012      Yue Zeng graduated with her M.S. Congratulations!.

August 2012      Hongyi's research highlighted at NCAR.
Jiajue Chai presented a poster and Hongyi Hu presented a talk at the ACS National Meeting in Philadelphia.

July 2012     Jiajue Chai passed his candidacy exam!
Also, three papers appeared this month:

1) Hongyi's first paper, Temperature-Dependent Branching Ratios of Deuterated Methoxy Radicals (CH2DOĽ) Reacting With O2, appears in print in the A. R. Ravishankara special issue of the Jounal of Physical Chemistry A.
2) CisľTrans Isomerization of Chemically Activated 1-Methylallyl Radical and Fate of the Resulting 2-Buten-1-peroxy Radical appears online in the Jounal of Physical Chemistry A ASAP.
3) The group's first paper on atmospheric mercury chemistry Thermodynamics of reactions of ClHg and BrHg radicals with atmospherically abundant free radicals appears in Atmospheric Chemistry and Physical Discussions.

June 2012     Jiajue Chai and Hongyi Hu presented a poster.
The poster was presented at the 22nd International Symposium on Gas Kinetics. Entitled Temperature-Dependent Rate constants of regular and fully deuterated methoxy radical reacting with O2,the poster combined results from 2 experiments:
a) Hongyi's studies, carried out at NCAR, of the rate constant ratios for CH3OĽ and CD3OĽ reacting with O2 versus NO2.
b) Jiajue Chai's direct determination of the rate constant for CH3OĽ and CD3OĽ reacting with NO2.

March 2012     Hongyi Hu's first paper is accepted at The Journal of Physical Chemistry A!
The papers is an experimental study of the Temperature-Dependent Branching Ratios of Deuterated Methoxy Radicals (CH2DOĽ) Reacting With O2.
Ted presented two talks and two posters at the ACS Meeting in San Diego. The actual research was done by graduate students Hongyi Hu and Yuan Sha, undergraduates Matt Zelie and William Thornton, and postdoc Feng Zhang.

February 2012     Dr. Feng Zhang is promoted!
Former postdoc Feng Zhang is promoted to a tenure track Research Associate position at USTC.

October 2011     Cover article in Physical Chemistry Chemical Physics!
Article on tunneling in H-shift reactions of a prototypical peroxy radical.














August 2011     Yuge Jiao joins the group as a Ph.D. student.
He is interested in applying computational methods to kinetics and mechanisms of reactions in atmospheric chemistry.

July 2011     Dr. Feng Zhang returns to China
We will miss Dr. Feng Zhang and wish her well in her new postdoctoral position at USTC in the research group of Dr. Fei Qi.

July 2011     Presentations by group members
Feng Zhang and Hongyi Hu gave talks on their research at the 7th International Conference on Chemical Kinetics at MIT.
Ted presented two posters at the 31st International Symposium on Free Radicals in Port Douglas, Australia.
Matt Zelie presented a poster on atmospheric mercury chemistry at the 10th Annual Conference on Undergraduate Computational Chemistry

March 2011     Presentations by group members
In January, Feng Zhang and Hongyi Hu gave talks on their research at the 29th Regional Kinetics and Dynamics Meeting.
In March, Feng Zhang traveled to MIT to present her work to the research group of William H. Green. Later this month, she will present a talk at the 7th U.S. National Combustion Meeting in Atlanta, GA.

December 2010    Karen Schmitt passes her M.S. thesis defense!
Karen presented her capstone seminar and then passed the oral defense of here M.S. thesis on Tuesday, December 14, 2010. Her thesis title is Investigating the Chemical Mechanism Initiated by Electron Beam Irradiation of VOCs in Air. Congratulations, Karen!
Also this month, Hongyi Hu presented a poster at the Atmopsheric Chemical Mechanisms conference at UC-Davis and at the 2010 AGU Fall Meeting.

October 2010    Ted gives a talk at UNH
    Ted gave an invited lecture at the Chemistry Department of the University of New Hampshire this month.

September 2010    Travel by Group members!
    Hongyi returned from 8 months spent working with Geoffrey Tyndall of the Atmospheric Chemistry Division of NCAR in Boulder, Colorado. While in Boulder, Hongyi used FTIR to determine the ratio of products of the CH2DO• + O2 reaction, which produces HCH=O (normal formaldhyde) or DCH=O. The ratio of production of these isotopologues strongly affects atmospheric HD/H2 ratios, observations of which are used to evaluate the global budget of molecular hydrogen. She also investigate the competition of alkoxy radicals reacting with O2 and NO2.
    Also this month, Feng visited the research group of Donald Truhlar at the University of Minnesota. Dr. Truhlar and his group graciously hosted Feng for two days to help her learn their software for computing rate constants using variational transition state theory and multidimensional tunneling.

March 2010     New postdoc joins the group.
    Feng Zhang joins the Dibble group as a postdoctoral research associate. She holds two Ph.D. degrees: one in Physical Chemistry from Beijing Normal University, and a second in Theoretical Chemistry from the Royal Institute of Biotechnology in Sweden. She is working on desecribing the reactions of models of peroxy radicals that are responsible for ingnition of biodiesel fuel.

November 2009     Research of former undergrad highlighted in Nature!
    Alyson Lanciki (B.S. 2006) is doing her Ph.D. research with Professor Cole-Dai at South Dakota State University. Her thesis research includes work published in Geophysical Research Letters and highlighted under "Volcano Chills" in the November 12 issue of Nature. Congratulations, Alyson!

September 2009         Graduate student Karen Schmitt publishes her first paper!
Karen Schmitt published her first paper, entitled Towards a Consistent Chemical Kinetic Model of Electron Beam Irradiation of Humid Air in the journal Plasma Chemistry and Plasma Processing. Congratulations, Karen!

February 2009     The Dibble Mechanism!
    Final version of CalTech paper which first names the "Dibble Mechanism" published Atmospheric Chemistry and Physics! In 2004, Dr. Dibble published a pair of back-to back papers (see here and here) on the simultaneous double H-atom transfer reaction in alkoxy radicals from isoprene (2-methyl-1,3-butadiene). This fascinating reaction appears to be of real importance in isoprene chemistry.
