Public Lecture: Chemical origins of our solar system and ancient stars as viewed through atomic-scale studies of planetary materials

Speaker: Professor Thomas Zega, University of Arizona
Date: May 30, 2019  Time: 1:30 PM  Location: BSB 147

Thomas Zega is Associate Professor in the Lunar and Planetary Laboratory and the Dept. of Materials Science and Engineering at the University of Arizona. He is the Scientific Director of the Kuiper Materials Imaging and Characterization Facility at the University of Arizona and the PI of the planetary-materials research group that examines those pieces of condensed matter that were leftover from the time that our solar system formed over 4.5 billion years ago. His current research efforts are focused on: the origin of the presolar grains, nm to μm-sized dust particles that formed inside of ancient stars but preserved inside of primitive meteorites; the structure and crystal chemistry of 4.6-billion-year-old refractory inclusions in meteorites that are the first solar-system solids; the functional chemistry and preservation state of primitive pre-biotic organic compounds that formed in the early solar system and interstellar space; and the development of analytical techniques for investigations of such materials. Prior to joining the University of Arizona, he was a National Research Council Postdoctoral Fellow and later staff scientist at the Naval Research Laboratory, Washington DC, where his work focused on using electron microscopy to investigate spintronic materials, catalysts, photovoltaic materials, and the origins of planetary materials.

Annual CCEM Art Gallery Competition

The CCEM will be holding its second annual image competition to fill our art gallery! The images can be black and white or have false colouring added; it is up to your artistic discretion.

Requirements:
-Please send images in tiff format to ccemreg@mcmaster.ca with the following file extension “firstname_lastname_art”. In the email indicate:

  1. your affiliation
  2. the name of your art piece
  3. the material imaged
  4. the name of the microscope operator (if applicable)

-Only one image can be submitted per user! Image may not have been submitted in previous competition.
-The images must be acquired at the CCEM
-The submitted images should be 11.75 inches x 11.75 inches (width x height)

Deadline: April 26, 2019

Selection Process:
A vote will then be had by all CCEM users to select the top six images that will be featured in the art gallery.

Finalists will be featured at the CCEM User meeting (registration to open soon) and in the CCEM art gallery for the 2019 season!

New CCEM Grants Available!

The CCEM is excited to announce our new grant program that provides in-kind service.  A competition will be held every three months for individuals who have not used the CCEM in the last two years and show financial need. The grant can only be won once.  A judging panel will select the winner based on the submitted proposal and its potential to result in new publications. Applications can be submitted on Nanolims. Instructions for creating a Nanolims account can be found in the FAQ.

Submission Guideline:
The submission form is available on NanoLIMS and an account is necessary to submit.

Proposal Outline
Your proposal should include the following:

  • Explain the project objective
  • How can the CCEM be useful?
  • How much time is required to complete the project?

Special Seminar: Aberration-corrected STEM and ultra-high energy resolution EELS

The CCEM would like to welcome Dr. Ondrej L. Krivanek on Monday, February 11, 2019 to give a special seminar.

Speaker: Dr. Ondrej L. Krivanek, FRS, is co-founder and president of Nion Co, and Affiliate Professor at Arizona State U
Date: Monday, February 11, 2019
Time: 11 AM
Location: JHE H324

Dr. Krivanek has a Ph.D. from Cambridge U., and he is well known for developing new instruments for electron microscopy including parallel detection EEL spectrometers, imaging filters, CCD cameras, the first working STEM aberration corrector, and whole electron microscope columns, and applying the new instrumentation to important materials problems.
