My research interests on materials issues related with environment and energy. Currently, my group is focusing on two separate projects. In one of them, we are trying to develop CO2absorbentsthatcanbeusedrepetitivelyinthetemperaturerangeof300-500°C. Such a material is considered to be an integral part for the development of a carbon capture process which may become a major workhorse in reducing the emission of CO2and,hence,inaddressingtheissueofglobalwarming.Intheotherproject,wearetryingtounderstandandutilizesonochemistryinobtainingnovelnanomaterials.Especially,wehavedevelopedanewreactionschemetosynthesizecore-shellnanoparticleswithPtintheshellandvariousmetalsinthecore,whichfeaturesarehighlysoughtforinmanyapplicationfieldsincludingcatalysisforfuelcells.
