Rigaku Virtual Conference on XRD and XRF August 4-6!

Rigaku will be hosting a virtual conference on XRD and XRF this week that is free to register here!

Due to the COVID-19 induced cancellations of the Microscopy & MicroAnalysis, Denver X-ray, and American Crystallographic Association physical conferences this summer, Rigaku will be live webcasting a 3-day virtual Analytical X-ray Convention from our laboratory facility in Texas. The webcasts will take place Tuesday 8/4 – Thursday 8/6 and will feature live seminars on X-ray techniques and live instrument demonstrations.

Enjoy the presentations on Channel 1 (XRD), Channel 2 (XRF) and Channel 3 (X-ray Microscopy), and make sure to stop by our Concierge Booth on Channel 4 to say hello, live video chat, and participate in some fun events. We will be announcing upcoming Channel 4 events on the channel itself and via our Rigaku twitter feed (@rigaku, hashtag #RAXC2020), which you can view see on the right to keep up to date with what is going on.

Check the starting times for each day in the program, as different channels have different starting times. All four channels will be broadcast simultaneously and you can move among the four booths using the channel links.

Note that the three guest presentations—to be given by Rigaku sponsors—will all take place on channel 3. This has been updated on the program schedule.

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

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.

Webinar – How is Particle Size Measured

Masterclass
October 23
10:30 ET
The MCF will be showing this webinar on the monitor in Marcus at 10:30AM on October 23rd.
—-
There is a gamut of particle size distribution measurement techniques each with established history and advantages.

The killer word in particle size distribution is the last one (distribution) and measurement of broad distributions is the bane of all sizing techniques.

After a very short introduction to ‘how much sample should we measure to describe the distribution’, we’ll be running through the background of some of the more popular techniques (sieves, sedimentation, electrical-sensing zone) and will emphasize the popular light scattering techniques of laser diffraction and dynamic light scattering.

As an aside, we’ll be mentioning Small-Angle X-ray Scattering (SAXS).

SEM and EDS Short Course

The Materials Characterization Facility (MCF) at Georgia Tech will offer a short course on “Scanning Electron Microscopy and Energy Dispersive X-ray Spectrometry (EDS)” on October 8 & 9, 2018. This 2-day short course combines lectures and laboratory, and is designed for individuals interested in hands-on training in scanning electron microscopy techniques.

This short course will cover essential signal generation and detection techniques, including secondary and backscatter electrons, X-rays, low voltage imaging, and sample preparation techniques. Attendees will learn how to adjust operating conditions to gain valuable information about material samples. This course is suitable for both new and experienced researchers.
