Thermal modification of ZrCu metallic glass nanolaminates: Structure and mechanical properties
Andrea Brognara, Chanwon Jung, Cristiano Poltronieri +4
The effects of thermal treatments on metallic glass nanolaminates (NLs), with a composition of ZrCu and ZrCu and a bilayer period of 50 nm, were explore…
Facilitating the systematic nanoscale study of battery materials by atom probe tomography through in-situ metal coating
Mahander P Singh, Eric V Woods, Se Ho Kim +3
Through its capability for 3D mapping of Li at the nanoscale, atom probe tomography (APT) is poised to play a key role in understanding the microstructural degradation of lithium-i…
In-situ metallic coating of atom probe specimen for enhanced yield, performance, and increased field-of-view
Tim M. Schwarz, Eric Woods, Mahander P. Singh +7
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…
Exploring the Surface Segregation of Rh Dopant in PtNi Nanoparticles through Atom Probe Tomography Analysis
Se-Ho Kim, Hosun Jun, Kyuseon Jang +3
Proton exchange membrane fuel cells hold promise as energy conversion devices for hydrogen-based power generation and storage. However, the slow kinetics of the oxygen reduction at…
Revealing compositional evolution of PdAu electrocatalyst by atom probe tomography
Leonardo Shoji Aota, Se-Ho Kim, Chanwon Jung +2
Pd-based electro-catalysts are a key component to improve the methanol oxidation reaction (MOR) kinetics from alcohol fuel cells. However, the performance of such catalysts is degr…
Atom probe analysis of BaTiO3 enabled by metallic shielding
Se-Ho Kim, Kihyun Shin, Xuyang Zhou +6
Atom probe tomography has been raising in prominence as a microscopy and microanalysis technique to gain sub-nanoscale information from technologically-relevant materials. However,…
Atomic scale evolution of the surface chemistry in Li[Ni,Mn,Co]O2 cathode for Li-ion batteries stored in air
Mahander P. Singh, Se-Ho Kim, Xuyang Zhou +6
Layered LiMO2 (M = Ni, Co, Mn, and Al mixture) cathode materials used for Li-ion batteries are reputed to be highly reactive through their surface, where the chemistry changes rapi…
