  • Afsana Chowdhury and Maliha Chowdhury join group

    A big welcome to Afsana Chowdhury and Maliha Chowdhury who have joined the group as graduate students!

  • New publication in Chem. Commun.

    We have a new paper out in Chem. Commun.! In this work, Will, Georgia, Nirob, and Chamoni show that pyridines reversibly form adducts with carbodiimides, lowering their effective concentrations in solution. This allows the activation rates and lifetimes of carbodiimide-driven systems to be controlled.

  • Sujin Waikhom and Henry Oliver join group

    Welcome to Sujin Waikhom and Henry Oliver, who have joined the group as undergraduate researchers!

  • Belated welcome to Olivia Freeman and Max Kovall

    We forgot to post Olivia and Max when they joined the group last spring as undergraduate researchers. Welcome!

  • Will graduates

    Happy trails to Will Salvia, who successfully defended his M.S. thesis! Will is off to Northwestern to do his Ph.D.

  • New publication in Angew. Chem.

    We have another new paper out in Angew. Chemie.! In this one, Nirob and Will report on the formation of transient covalent polymers using carbodiimide-driven anhydride formation. These systems are intended to complement the many examples of out-of-equilibrium supramolecular polymers, by offering different characterization methods and control over assembly kinetics.

  • New publication in Angew. Chem.

    We have a new paper out in Angew. Chem.! Chamoni, Corvo, and Will report on how network architecture affects the properties of polymer materials with temporary crosslinks generated by carbodiimides. Materials that generate interpenetrated networks on treatment with the carbodiimide show remarkable increases in their fracture energies (resistance to fractures).

  • New publication in J. Chem. Educ.

    We have a new paper out in J. Chem. Educ.! Suma and Jake developed an activity for second-year organic chemistry labs that explores out-of-equilibrium systems chemistry. It is based on the work we (and others) have done developing carbodiimide-driven processes.
