Measurement & Characterization December Demo Days in Pettit 160

 

On Thursday and Friday, December 2nd & 3rd, the MCF in coordination with the IEN is hosting two days of measurement and characterization in the Pettit Microelectronics Building.

We plan to highlight previously available and new capabilities added over the last year for 2D, 3D, x-ray, and elemental measurements.

Please bring samples you are interested in measuring and staff will be happy to help you.

Download the flyer below, and we hope to see you there!

Where: Pettit 160
When: December 2nd & 3rd | 10:00AM – 5:00 PM

If you have questions or concerns, please feel free to contact the MCF Staff:

New Crystalmaker Software Suite for 2021

The Crystalmaker Software suite is available for download for students and staff at Georgia Tech! The crystalmaker suite will enable you to create crystal models, simulate XRD patterns, and generate CIFs. For the codes, please contact David Tavakoli (david.tavakoli@mse.gatech.edu) from a GT email address.

Safety Videos Required for Returning to Campus

The MCF Staff look forward to welcoming our users back to campus and hope you are all safe and well.

From the office of the EVPR:

Research Ramp-Up Details

 

As part of a careful, gradual return to campus operations, research ramp-up activities are anticipated to begin as early as June 18. Only researchers and staff who must return to campus in order to carry out their job duties should return to work on campus. Supervisors will provide specific direction to their teams on when to return to in-person work. Anyone with questions about when or how they should start reporting to work in-person should, first, ask their supervisor.

Required: “Returning Safely to Your Lab” Video

If you have been identified by your supervisor to return to your lab, or if you have been working in one of the labs that has remained open, you will be required to watch the “Returning Safely to Your Lab” videos. The six-part module will include what you can expect, recommended safety precautions, cleaning and disinfection best practices, and proper use and disposal of PPE, among other helpful tips for best ensuring your safety and the safety of others.

Video Instructions:

  • Access the video by logging in at https://training.osp.gatech.edu/.
  • Click “My Online Classes” in left menu.
  • Select the first item: “Returning Safely to Your Lab.”
  • In “Available Courses” – click “Returning Safely to Your Lab.”
  • Click ‘Enroll Me.’
  • There are six video segments — when finished with each segment, go to the menu on the left side of the screen to start the next video.
  • After segment six, click Quiz in the menu and follow next steps to record that you have viewed the videos.
 
 

Webinar: Focus on Battery Research: Studying Battery Cathode Materials Using X-Ray Diffraction

Tuesday, April 22: 10:30-11:30AM.

The cathode in a lithium-ion battery undergoes unique electrochemical reactions as lithium enters and leaves the atomic structure of the intercalated lithium compound. The intricacies of this reaction are one source of degradation and, therefore, an opportunity to improve performance. X-ray diffraction and scattering is well-suited to study these atomic phase changes, as well as a tool to understand and optimize the pathways that lithium uses to move through the cathode. However, studying battery materials requires special considerations that are different than the routine powder diffraction measurement.

This webinar, hosted by Malvern PANalytical will review the information that X-ray diffraction and scattering provides and discuss special considerations for experimental design such as selecting an X-ray tube, measurement geometry, and sample holder. We will then show examples of how these considerations are applied to cathode material analysis, including Rietveld refinement to quantify phase mixtures and atomic structure, pair distribution function analysis to examine local structural defects, and phase analysis of thick (10mm) commercial pouch cells, and in operando analysis of LFP based batteries to track phase changes during discharge and charging.

You can sign up for it here.

Speakers

Dr. Scott Speakman – Principal Scientist Malvern Panalytical
and Dr. Reeves-McLaren of The University of Sheffield

More information

– Who should attend?
Those working within the field of battery research or manufacturing or anyone interested in X-ray Diffraction of materials.
– What will you learn?
You will be educated on the X-ray diffraction and scattering application of lithium-ion batteries, including: Electrochemical reactions and atomic phase changes, with discussion on the special considerations needed for this application.

 

SingleCrystal for Mac and Windows is now released!

The client for SingleCrystal is now out of Beta and available for GT users! If you would like the license, please send an email to David.Tavakoli@mse.gatech.edu from your GT mailing address!

As a reminder, all of the Crystalmaker software suite is available for Georgia Tech and we hope that you are well, safe, and healthy!

From the classroom to the laboratory to the synchrotron: SingleCrystal is the easiest way to visualize and understand diffraction properties of crystals. SingleCrystal 4 lets you simulate multi-phase X-ray, neutron and electron diffraction patterns, display reciprocal lattice sections and construct stereographic projections of planes or vectors. By combining a simulated pattern with an observed diffraction image, you can auto-index the pattern and determine the orientation of your crystal.

Shared User Facilities Will be closed at 5:00PM, Thursday, March 19th, 2020

All Georgia Tech shared-user facilities will be ramping down research activities in response to the ongoing COVID-19 threat.

To comply with the directive from our administration, the MCF will close at 5:00PM this Thursday. All characterization work needs to be complete by 3:00 pm on Thursday without exception.

Equally importantly, please make sure to recover any data that you need to work remotely before that time.

There is no announced date about when the MCF will reopen, so please check Georgia Tech news regularly.

Further details and updates about the impact on research can be found here, and we will be sending SUMS/email announcements as updates occur.

Updates on the Georgia Tech community and the Covid-19 virus can be found here along with a FAQ.

In situ heating holder has been installed in Hitachi HD2700

We recently purchased an in situ heating holder from Hitachi and installed it in the aberration corrected STEM Hitachi HD2700. The heating temperature can increase up to 1200C. The in situ heating experiments performed in the aberration corrected STEM can allow you to directly observe the phase transformation, nanoparticle crystallization and growth, atomic cluster or single atom rippening, phase segregation, elemental homogenization, and many others at atomic scale. Currently we hold two types of heating chips w/ or w/o hole in thin SiNx membrane. But the hitachi company offer many selections of heating chips available to buy in small quantity i.e. 5/pk.

If you need to know anything more about the heating experiment or training in the STEM, please contact Mengkun Tian.
