Atomic motifs govern the decoration of grain boundaries by interstitial solutes
Xuyang Zhou, Ali Ahmadian, Baptiste Gault +4
Grain boundaries, the two-dimensional (2D) defects between differently oriented crystals, control mechanical and transport properties of materials. Our fundamental understanding of…
Chemical Partitioning at Crystalline Defects in PtAu as a Pathway to Stabilize Electrocatalysts
Xuyang Zhou, Olga Kasian, Ting Luo +8
Dissolution of electrocatalysts during long-term and dynamic operation is a challenging problem in energy conversion and storage devices such as fuel cells and electrolyzers. To de…
Effect of Pore Formation on Redox-Driven Phase Transformation
Xuyang Zhou, Yang Bai, Ayman A. El-Zoka +7
When solid-state redox-driven phase transformations are associated with mass loss, vacancies are produced that develop into pores. These pores can influence the kinetics of certain…
Understanding the degradation of a model Si-anode in Li-ion battery at the atomic-scale
Se-Ho Kim, Kang Dong, Huan Zhao +7
Si-anodes have long been candidates thanks to an expected ten-fold increase in capacity compared to graphite. However, details of the mechanisms governing their degradation remain…
Revisiting stress-corrosion cracking and hydrogen embrittlement in 7xxx-Al alloys at the near-atomic-scale
Martí López Freixes, Xuyang Zhou, Huan Zhao +4
Hydrogen embrittlement (HE) affects all major high-strength structural materials and as such is a major impediment to lightweighting e.g. vehicles and help reduce carbon-emissions…
