Graduate student, Ben Yeh successfully defended his qualifying PhD exam on the topic “Mechanism and active site requirements for olefin oligomerization on metal-organic framework catalysts.”Congratulations, Ben!
Several Gagliardi Group members have collaborated on a recent JCTC publication, “Automation of Active Space Selection for Multireference Methods via Machine Learning on Chemical Bond Dissociation.”Postdoc WooSeok Jeong, former graduate student Sam Stoneburner, and Laura designed a project aimed at popularizing CASSCF by making it easier to select good active spaces. In collaboration with first-year graduate student Daniel King, undergraduate Andrew Walker, visiting undergraduate Ruye Li from Tsinghua University, and Professor Roland Lindh from Uppsala University, they developed a machine learning protocol that performs an automated selection of active spaces for chemical bond dissociation calculations of main group diatomic molecules.
In collaboration with scientists from the Los Alamos National Laboratory, Laura and former postdoc Jing Xie (currently an assistant professor at the School of Chemistry and Engineering, Beijing Institute of Technology, Beijing, China) have synthesized and characterized the first 2-metallabiphenylene compounds, advancing the knowledge of actinide systems that can show unique spectroscopies and reactivities.
In a highly collaborative work, researchers were able to report the activation of C2 and C3 alkanes over well-defined, mononuclear iron sites situated within the nodes of a MOF that bear similar nuclearity, oxidation state (+2), and spin state (S=2) to iron centers in certain enzymes that activate alkanes oxidatively. Experiments characterizing the bulk structure of the MOF and its reactivity were performed by Gagliardi group graduate student Matthew Simons (co-advised by Aditya Bhan), and Jenny Vitillo, Ph.D., Gagliardi group postdoc (co-advised by Connie Lu), performed the synthesis and quantum mechanical characterization of the material. This study has recently been reported in the Journal of the American Chemical Society.
She gave a statement on “Modeling functional materials with electronic structure theories.
Three papers were accepted in the first week of August:
- Beyond Density Functional Theory: The Multiconfigurational Approach To Model Heterogeneous Catalysis
- Spin State Ordering in Metal-Based Compounds Using the Localized Active Space Self-Consistent Field Method
- Hydrogen Atom or Proton Coupled Electron Transfer? C-H Bond Activation by Transition Metal Oxides
The 7th Annual OpenMolcas Developers’ Workshop took place on June 12-14, 2019 at the University of Minnesota. The workshop consisted of a mixture of technical and scientific reports from Molcas developers, scientific perspectives from Molcas users, and discussion sessions. Many Gagliardi group members presented, including Carlo Alberto Gaggioli, Matthew Hermes, Riddhish Pandharkar, Thais Scott, and Prachi Sharma. The workshop was sponsored by Molcas and by the Inorganometallic Catalyst Design Center. It was hosted by the Minnesota Supercomputing Institute.
Eight undergraduate students are participating in the 2019 Summer Theoretical Chemistry Research Fellowship program, hosted by the Chemical Theory Center (CTC), including 4 in the Gagliardi Group – Janey Lin (Mount Holyoke College), Erica Mitchell (Taylor University), Samuel Powell (Ohio Northern University), and Claire Shugart (Carlton College).
Graduate student, Thais Scott published her first paper as a member of the group, “A Multireference Ab Initio Study of the Diradical Isomers of Pyrazine. Congratulations!
