Strain Relaxation in Core-Shell Pt-Co Catalyst Nanoparticles
Elliot Padgett, Megan E. Holtz, Anusorn Kongkanand +1
Surface strain plays a key role in enhancing the activity of Pt-alloy nanoparticle oxygen reduction catalysts. However, the details of strain effects in real fuel cell catalysts ar…
Revealing the Nanostructure of Mesoporous Fuel Cell Catalyst Supports for Durable, High-Power Performance
Matthew Ko, Elliot Padgett, Venkata Yarlagadda +2
Achieving high power performance and durability with low Pt loadings are critical challenges for proton exchange membrane fuel cells. PtCo catalysts developed on new carbon black s…
The Exit-Wave Power-Cepstrum Transform for Scanning Nanobeam Electron Diffraction: Robust Strain Mapping at Subnanometer Resolution and Subpicometer Precision
Elliot Padgett, Megan E. Holtz, Paul Cueva +4
Scanning nanobeam electron diffraction (NBED) with fast pixelated detectors is a valuable technique for rapid, spatially resolved mapping of lattice structure over a wide range of…
Sampling Limits for Electron Tomography with Sparsity-exploiting Reconstructions
Yi Jiang, Elliot Padgett, Robert Hovden +1
Electron tomography (ET) has become a standard technique for 3D characterization of materials at the nano-scale. Traditional reconstruction algorithms such as weighted back project…
Nanomaterial datasets to advance tomography in scanning transmission electron microscopy
Barnaby D. A. Levin, Elliot Padgett, Chien-Chun Chen +17
Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for devel…
Pinning Susceptibility: The effect of dilute, quenched disorder on jamming
Amy L. Graves, Samer Nashed, Elliot Padgett +3
We study the effect of dilute pinning on the jamming transition. Pinning reduces the average contact number needed to jam unpinned particles and shifts the jamming threshold to low…
