3D atomistic imaging of polymer nanocomposites with Atom Probe Tomography: experimental methodology, preliminary results and future outlook
James O. Douglas, Reza Salehiyan, Aparna Saksena +5
The use of polymer nanocomposites as gas barrier materials has seen increasing interest, including applications involving hydrogen transport and storage. Better understanding of ga…
Vacuum Dealloyed Brass as Li-Metal Battery Current Collector: Effect of Zinc and Porosity
Eric V Woods, Xinren Chen, Shaolou Wei +19
"Anode-free" lithium-metal batteries promise significantly higher energy density than conventional graphite-based lithium-ion batteries; however, lithium dendrite growth can lead t…
Atom probe tomography of hydrated biomacromolecules: preliminary results
Shuo Zhang, Leonardo Shoji Aota, Mahander P. Singh +4
The folding and structure of biomacromolecules depend on the 3D distributions of their constituents, which ultimately controls their functionalities and interactions with other bio…
Advancing atom probe tomography capabilities to understand bone microstructures at the near-atomic scale
Tim M. Schwarz, Maïtena Dumont, Victoria Garcia-Giner +3
Bone structure is generally hierarchically organized into organic (collagen, proteins,...), inorganic (hydroxyapatite (HAP)) components. However, many fundamental mechanisms of the…
Towards establishing best practice in the analysis of hydrogen and deuterium by atom probe tomography
Baptiste Gault, Aparna Saksena, Xavier Sauvage +42
As hydrogen is touted as a key player in the decarbonization of modern society, it is critical to enable quantitative H analysis at high spatial resolution, if possible at the atom…
Mapping the path to Cryogenic Atom Probe Tomography Analysis of biomolecules
Eric V. Woods, Tim M. Schwarz, Mahander P. Singh +7
The understanding of protein structure, folding, and interaction with other proteins remains one of the grand challenges of modern biology. Tremendous progress has been made thanks…
Nanoporous gold thin films as substrates to analyze liquids by cryo-atom probe tomography
E. V. Woods, A. Saksena, A. A. El-Zoka +7
