MIAM Trainee Showcase - Electron Tomography and AC/DC-Scanning Electrochemical Microscopy

Wanting He / ELECTRON TOMOGRAPHY

Wanting He is a Postdoctoral Researcher at the McGill Facility for Electron Microscopy Research (FEMR). Electron tomography (ET) enables the three-dimensional (3D) reconstruction of nano-structures from a series of two-dimensional (2D) projections acquired over a range of viewing angles, providing significantly richer morphological and structural information than conventional 2D imaging. In this talk, Wanting will introduce the electron tomography techniques developed at FEMR. These approaches enable 3D structural, chemical, and electronic property imaging of materials with nanometer and sub-nanometer spatial resolution.

Changyue Du / AC/DC-SCANNING ELECTROCHEMICAL MICROSCOPY

Changyue Du is a Ph.D. candidate in department of chemistry supervised by Prof. Janine Mauzeroll. Her Ph.D. research focuses on electrochemical pH sensing and pH imaging using scanning electrochemical microscopy (SECM). SECM is an analytical electrochemical technique utilizing microelectrodes which collect high-resolution material electrochemical properties within micron-scale distance to the sample surface. Changyue will be focus on working principles and applications of SECM, and how alternating current (AC)-SECM can provide rich information compared to conventional direct current SECM.
