Mapping the path to Cryogenic Atom Probe Tomography Analysis of biomolecules

Autor: Woods, Eric V., Schwarz, Tim M., Singh, Mahander P., Zhang, Shuo, Kim, Se-Ho, El-Zoka, Ayman A., Gremer, Lothar, Willbold, Dieter, McCarroll, Ingrid, Gault, B.

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 to X-ray- or electron-based techniques that have provided atomic conf

Analysis of water ice in nanoporous copper needles using cryo atom probe tomography

Autor: Tegg, Levi, McCarroll, Ingrid E., Kim, Se-Ho, Dubosq, Renelle, Woods, Eric V., El-Zoka, Ayman A., Gault, Baptiste, Cairney, Julie M.

The application of atom probe tomography (APT) to frozen liquids is limited by difficulties in specimen preparation. Here, we report on the use of nanoporous Cu needles as a physical framework to hold water ice for investigation using APT. Nanoporous

Report

In-situ metallic coating of atom probe specimen for enhanced yield, performance, and increased field-of-view

Autor: Schwarz, Tim M., Woods, Eric, Singh, Mahander P., Jung, Chanwon, Aota, Leonardo S., Jang, Kyuseon, Krämer, Mathias, Kim, Se-Ho, McCarroll, Ingrid, Gault, Baptiste

Atom probe tomography requires needle-shaped specimens with a diameter typically below 100 nm, making them both very fragile and reactive, and defects (notches at grain boundaries or precipitates) are known to affect the yield and data quality. The u

Report

Chemical and structural characterization of the native oxide scale on a Mg-based alloy

Autor: Neuß, Deborah, McCarroll, Ingrid E., Zhang, Siyuan, Woods, Eric, Delis, Wassilios J., Tanure, Leandro, Springer, Hauke, Sandlöbes, Stefanie, Yang, Jing, Todorova, Mira, Zander, Daniela, Scheu, Christina, Schneider, Jochen M., Hans, Marcus

In this study, the structure and composition of the native oxide forming on the basal plane (0001) of Mg-2Al-0.1Ca is investigated by a correlative approach, combining scanning transmission electron microscopy (STEM) and atom probe tomography (APT).
