(NUCAPT)

Browse: Tools | Research | People | MRSEC

NUCAPT specializes in high-resolution chemical imaging by three-dimensional atom probe tomography (APT). APT produces a three-dimensional (3D) atom-by-atom chemical image with sub-nanometer spatial resolution of a sample volume typically 100 x 100 x 300 nm^3, by simultaneous high resolution imaging and atom-by-atom time of flight mass spectrometry. APT is particularly suited to study nano- or nanostructured materials.


The historic VG FIM100 atom-probe field-ion microscope (APFIM) was on display in Terminal 1 at O'Hare Airport in the concourse opposite gate B12 from May 2016 through October 2017. It was moved to O'Hare Airport to spend part of its retirement days among applications of the high-performance structural and areo-space materials it helped develop.

NUCAPT had originally donated the VG FIM100 APFIM to Chicago's Museum of Science and Industry where it anchored the exhibition Materials Science at MSI (press kit). The Chicago Tribune ran an article about the exhibition "Materials Science" at the MSI on March 25, 2015.

  • Professor David Seidman is receiving the 2020 Distinguished Scientist Award of the Microscopy Society of America. This Award recognizes preeminent senior scientists from both the Biological and Physical disciplines who have a long-standing record of achievement during their career in the field of microscopy or microanalysis. Congratulations, David!
  • Congratulations to Professor David Seidman for receiving the 2019 Peter Duncumb Award for Excellence in Microanalysis from the Microanalysis Society (MAS). The award ceremony was held at the M&M2019 conference in Portland, OR, on Aug. 5th, 2019.
  • Professor David Seidman was awarded the 2019 Gold Medal from ASM International, “for quantitative applications of field-ion microscopy and atom-probe tomography for solving a very broad range of materials problems from different materials classes in conjunction with other characterization tools.” Seidman will officially receive the medal at the MS&T19 conference in Portland, OR. Congratulations!
  • Congratulations to Professor David Seidman for his election to the National Academy of Engineering (NAE). Election to the academy is among the highest professional distinctions accorded to an engineer. Seidman is one of 83 new members and 16 new foreign members announced by the NAE on February 7, 2018. Seidman was cited by NAE for “contributions to understanding of materials at the atomic scale, leading to advanced materials and processes.” He will be formally inducted during a ceremony at the NAE’s annual meeting on September 30, 2018 in Washington, D.C.
  • Congratulations on Dr. Dieter Isheim's winning the AIME Champion H. Mathewson Award, 2016. This is a very prestigious award from the TMS, which award is named after Champion H. Mathewson. Chammpion H. Mathewson was a pioneering physical metallurgist in the USA, who had most of his career at Yale University, 43 years. A round of applause for Dr. Dieter Isheim.
