Title: Transition metal oxides for electronics and spin-electronics

​

Abstract: The strongly correlated oxides have a wide range of unique behaviors owing to the interplay of the spin – charge – lattice – orbital degrees of freedom. In this presentation, I will summarize my previous research on the investigation of electrical transport properties of nanostructures of a 3d transition metal oxide using the THz Time Domain Spectroscopy, toward the electronic application. Moreover, I will introduce my on-going research on the oxides of 4d and 5d transition metals as a source for the spin current generation toward the low-power spin-electronic application. The potential investigations using optical and spectroscopic measurements such as TRMOKE and XPS and so on, will also be discussed, which call for the future collaborations between members of the Network.

Title: Selective ethylene production from CO2 and CO reduction via engineering gas diffusion electrode using Cu based electrocatalysts

​

Abstract: Conversion of carbon dioxide into hydrocarbons using renewable energy is an attractive strategy for storing such a renewable source of energy into the form of chemical energy (a fuel). This can be achieved in a system coupling a photovoltaic (PV) cell to an electrochemical cell (EC) for CO2 or CO reduction. To be beneficial and applicable, such a system should use low-cost and easily processable electrolyzer and display minimal energy losses associated with the catalysts at the anode and cathode. We have considered all of these parameters altogether to set up a different electrolyzer systems for CO2 conversion to hydrocarbons. By using the original and efficient Cu-based catalysts, we aim to get close to the requirements of industrial application for CO2 reduction to hydrocarbon.
