On August 2017, Letian is moving to Purdue University, Davidson School of Chemical Engineering as an assistant professor to start his independent scientific research career. The Dou group will focus on hybrid materials and nanomaterials for energy harvesting and electronics. Several graduate student positions are available. Visiting students/scholars are also welcomed. Send CV to dou10@purdue.edu.
On 4/12/2017, Letian will give an invited talk @Ohio State Univ., Department of Materials Science and Engineering. Looking forward to seeing many friends and colleagues there.
On 3/29/2017, Letian will give an invited talk @University of Groningen, Stratingh Institute for Chemistry. Looking forward to seeing many friends and colleagues there.
Fan’s paper on Cu nanowire synthesis using organic free radicals has been published on JACS. In this work, we report a new, general synthetic approach that uses heat driven benzoin radicals to grow ultrathin copper nanowires with tunable diameters. In-situ temperature dependent electron paramagnetic resonance (EPR) spectroscopic studies show that the active reducing agent is the free radicals produced by benzoins under elevated temperature. The nice thing is that the reducing power of benzoin can be readily tuned by symmetrically decorating functional groups on the two benzene rings. The controllable reactivity gives the carbon organic radical great potential as a versatile reducing agent that can be generalized in other metallic nanowire syntheses.
On 2/28/2017, Letian will give an invited talk @Purdue University, Department of Chemical Engineering. Looking forward to seeing many friends and colleagues there.
On 2/21/2017, Letian will give an invited talk @UMass Amherst, Department of Chemical Engineering. Looking forward to seeing many friends and colleagues there.
On 1/25/2017, Letian will give an invited talk @Yale University, Department of Mechanical Engineering and Materials Science. Looking forward to seeing many friends and colleagues there.
Yi’s paper on atomic resolution TEM imaging of halide perovskite nanosheets has been published on Nano Lett. This is the first report of the high quality atomic structures of halide perovskites using TEM. A quantitative structure determination was achieved atom column by atom column using the phase information of the reconstructed exit-wave function without causing electron beam-induced sample alterations.
On 10/28/2016, Letian will give an invited talk @UCLA MSE. Looking forward to see Prof. Yang and many friends there.
On 11/03/2016, in the “meet the candidate section”Letian will give a poster presentation in the 2016 AIChE annual meeting @San Francisco. This is related to job applications. Looking forward to meeting with the department chairs and search committees.
