Phys Chem/Chem Phys Seminar
A delicate balance between spin-orbit and other competing interactions inherent in 4d/5d materials offers a unique range of opportunities to uncover exotic states and physical properties that are intimately coupled to the crystal structure . This key characteristic provides us fertile ground to control quantum states by tuning the lattice of these materials. In this talk, we report our recent studies on electrical-current controlled phenomena in iridates  and ruthenates, and our recent observation of a quantum liquid state in an un-frustrated square lattice .
Many electrocatalytic reactions of current interest involve the transfer of multiple protons and electrons. Examples include the oxidations of methane and small organic molecules, as well as the reductions of nitrogen, nitrate, and carbon dioxide. These processes exhibit poor selectivity for specific desired products. This poor product selectivity hinders the adoption of these promising technologies. The aqueous electrochemical reduction of carbon dioxide to hydrocarbons on Cu electrodes is prototypical for this class of processes.
Revealing the chemistry in quantum chemistry: from diatomics to proton coupled electron transfer in enzymes
Quantum Chemistry has reached a state where most physical properties of molecules can be easily and accurately calculated—for example, DFT calculations of molecular structure, reaction mechanisms, and reaction energetics have become routine complements to organic chemistry.
