Crystal nucleation and growth in high-entropy alloys revealed by atomic electron tomography
Yakun Yuan, Saman Moniri, Yao Yang +8
High-entropy alloys (HEAs) balance mixing entropy and intermetallic phase formation enthalpy, creating a vast compositional space for structural and functional materials (1-6). The…
Streaming Large-Scale Electron Microscopy Data to a Supercomputing Facility
Samuel S. Welborn, Chris Harris, Stephanie M. Ribet +4
Data management is a critical component of modern experimental workflows. As data generation rates increase, transferring data from acquisition servers to processing servers via co…
Accelerating Time-to-Science by Streaming Detector Data Directly into Perlmutter Compute Nodes
Samuel S. Welborn, Bjoern Enders, Chris Harris +2
Recent advancements in detector technology have significantly increased the size and complexity of experimental data, and high-performance computing (HPC) provides a path towards m…
Imaging 3D Chemistry at 1 nm Resolution with Fused Multi-Modal Electron Tomography
Jonathan Schwartz, Zichao Wendy Di, Yi Jiang +15
Measuring the three-dimensional (3D) distribution of chemistry in nanoscale matter is a longstanding challenge for metrological science. The inelastic scattering events required fo…
Mapping electron beam-induced radiolytic damage in molecular crystals
Ambarneil Saha, Matthew Mecklenburg, Alexander J. Pattison +3
Every electron crystallography experiment is fundamentally limited by radiation damage. Nevertheless, little is known about the onset and progression of radiolysis in beam-sensitiv…
