Nanoporous gold thin films as substrates to analyze liquids by cryo-atom probe tomography
E. V. Woods, A. Saksena, A. A. El-Zoka +7
Cryogenic atom probe tomography (cryo-APT) is being developed to enable nanoscale compositional analyses of frozen liquids. Yet, the availability of readily available substrates th…
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…
Correlating atom probe tomography with X-Ray and electron spectroscopies to understand microstructure-activity relationships in electrocatalysts
Baptiste Gault, Kevin Schweinar, Siyuan Zhang +4
The search for a new energy paradigm with net-zero carbon emissions requires new technologies for energy generation and storage that are at the crossroad between engineering, chemi…
Enabling near-atomic-scale analysis of frozen water
Ayman A. El-Zoka, Se-Ho Kim, Sylvain Deville +3
Transmission electron microscopy has undergone a revolution in recent years with the possibility to perform routine cryo-imaging of biological materials and (bio)chemical systems,…
