Seidman Group

[edit] Nugget

A proxigram obtained from a LEAP tomographic dataset of a dilute Al-Sc-Lu alloy which has been aged at 300 deg C. Nanometer-sized Al₃(Sc_1-xLu_x) precipitates are exploited as a strengthening phase. This proxigram quantifies the core/shell structure which develops in the precipitates, with Lu segregating to the center of the precipitates and Sc forming a shell around the core.

• NUCAPT has been chosen as the profile of the day for 2007-10-08 by the Einstein@Home project. (APT analysis is highly interactive & so we have spare CPU cycles at night, which we donate to that project.)
• Ford's collaboration with NUCAPT has received a lot of press
• Danny Perea's article in Nano Letters is summarized by several press sources
• In Nature this week acknowledges The mechanism of morphogenesis in a phase separating concentrated multi-component alloy on the LKMC simulations of Ni-Cr-Al.
• Please give, won’t you? mentions the charitable contributions Rick has made to F/OSS on behalf of NUCAPT.
• ASM honors best in materials science and engineering tells of Professor David Seidman's receipt of the Albert Sauveur Achievement Award
• Zmanda Enhances Amanda Open Source Data Protection Software For Enterprise Use describes NUCAPT's backup system, which we use to protect our customer's data. Richard Karnesky is quoted.
• Redesigning the United States Navy with the Atom Probe is about the NUCu-150 steels studied by Dieter Isheim and others in the group.
• Northwestern adds to its Imago microscope describes NUCAPT's Laser enhancement.
• Atomic Imaging Turns 50 is the cover story in Chemical and Engineering News. It discusses the early history of Atom-Probe/Field-Ion Microscopy with Erwin Müller, as well as modern instrumentation such as the LEAP. Professor David Seidman is mentioned, as is Danny Perea's work on semiconductor nanowires.
