Three grad students win M&M scholar awards for outstanding papers

Written By: Adam Malecek

The Microscopy Society of America and the Microanalysis Society recognized three materials science and engineering graduate students for contributing outstanding papers for the 2017 Microscopy & Microanalysis (M&M) meeting.

Congli Sun, Chenyu Zhang and Pei Zhang, all members of Materials Science and Engineering Professor and Chair Paul Voylesresearch group, each received M&M student scholar awards.

Sun was honored for his paper, “Identification and quantification of boron dopant sites in antiferromagnetic chromium(III) oxide films by electron energy loss spectroscopy.” His research aims to identify and quantify boron dopants in possible lattice positions of chromium(III) oxide that potentially increase the magnetic ordering temperature of chromium(III) oxide.

Chenyu Zhang won the award for his paper, “Joint denoising and distortion correction for atomic column detection in scanning transmission electron microscopy images.” In this research, he focuses on applying Bayesian method to directly identify atom positions from noisy scanning transmission electron microscopy images, which enables a higher precision level in image analysis and lower electron dose during image acquisition.

Pei Zhang won the award for her paper, “Atomic-scale relaxation dynamics in the supercooled liquid state of a metallic glass nanowire by electron correlation microscopy.” In this research, she reports a visualization of the heterogeneous relaxation at atomic scale in the supercooled liquid state of Pt-based metallic glass nanowire via a time-resolved coherent electron scattering. This finding is important to understanding the dynamics when cooling from an equilibrium liquid state towards a non-equilibrium glassy state.

The award includes complimentary student registration for the full M&M 2017 meeting and financial support of up to $1,000 to help defray expenses to attend the meeting.
