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

New XANES/XAFS System Coming to the MCF!

The MCF is getting a new instrument capable of X-Ray Absorption Fine Structure (XAFS) and X-Ray Absorption Near Edge Structure (XANES).

This laboratory system for XAFS features a 1-2 kW conventional x-ray tube coupled to modern x-ray optics and detectors. It provides very rapid transmission-mode measurements suitable for research and development in electrical energy storage or catalysis while also giving extremely high throughput for general sample characterization or product testing. More details about the instrument can be found here from the instrument manufacturer.

 

Georgia Tech is hosting a workshop on XANES/XAFS techniques with an overview on Wednesday, December 11th and you can RSVP for that event here!

 

 

MCF is adding another XRD!

X-Ray Diffraction (XRD) is a powerful tool to look at crystals for characterizing microstructural and crystallographic properties of powders, thin films, fibers and other solid materials. The MCF has recently added another XRD, a Malvern PANalytical MPD to its capabilities. This XRD has a flat sample stage (default) for the analysis of powders and small solids, a non-ambient stage capable of running from -196C-450C, and a reflectivity stage. It should be on SUMS no later than 8/12/2019!

Webinar on Powder Diffraction by Malvern PANalytical

Introduction to Practical X-ray Powder Diffractometry

This presentation teaches the basic principles of X-ray diffraction and what information can be learned from an X-ray diffraction pattern. This presentation does not delve deeply into the mathematics or physics of diffraction, but rather focuses on illustrating the power of this materials analysis technique. It is intended for a broad audience—technicians, managers, students, professor moving from single crystal diffractometry into powder diffractometry, and those who are considering if X-ray diffraction could be a beneficial addition to their lab.

X-Ray Powder Diffraction is most often used to answer the questions: what is in the sample and how much? With modern diffractometers, it is possible to load a sample, push a single button, and get an answer. But … where did that answer come from? How reliable is it? What other information might be available in the data? This talk will dissect the X-ray powder diffraction pattern and show the wealth of information contained within.

More information can be found here.

Malvern PANalytical Aeris used by Georgia Tech students

The Aeris is a benchtop XRD capable of quick high resolution scans on powder samples or small solid samples. Conveniently it operates without the need of chiller water to operate and doesn’t have any exotic power requirements. Malvern PANalytical graciously allowed the Aeris to be housed in the Marcus Building and let students use it free of charge and several groups took advantage of it.

Malvern PANalytical Aeris in the XRD Lab

Malvern PANalytical has graciously housed the Aeris, their new benchtop XRD in the lab across from the Alpha-1. The Aeris is a easy to use XRD designed to run powder/pellet samples. This tool is free to use, and if you would like to get trained on it see how it runs your samples, please contact David Tavakoli (david.tavakoli@mse.gatech.edu) Tuesday or Wednesday of this week. Unfortunately on Thursday it will be shipped out to another lab.

Workshop on Non-Ambient XRD at North Carolina State Nov 8-9

A complimentary symposium created by the collaborative efforts of NCSU & Malvern PANalytical

Organized by: Professor Jacob L. Jones (NCSU) & Dr. Scott A. Speakman (Malvern PANalytical)

Agenda:
November 8, 2017 1:00pm – 5:00pm – Symposium
November 8, 2017 5:30pm – 7:00pm – Poster Session
November 9, 2017 9:00am – 4:00pm – Symposium

Non-ambient X-ray diffraction is a useful tool for determining phase stability, studying phase transformations, and following reaction pathways and kinetics. Practical examples include in-situ battery analysis for developing new cathode materials, understanding pharmaceutical stability with temperature and humidity, quantifying growth kinetics of nanocrystalline systems, and many more. New non-ambient chambers, faster instruments, and automatic data processing make non-ambient diffraction an ever-increasingly powerful technique. However, there are issues that can trip up the unwary, such as thermal gradients, unwanted reactions, systematic errors, etc. This symposium will feature lectures by leading researchers developing and using non-ambient diffraction on laboratory instruments, synchrotrons, and neutron beamlines. Lectures will focus on the research potential of non-ambient diffraction and practical advice for collecting accurate and useful data.

Attendees are encouraged to present a poster on their work related to this symposium. Speakers will judge the posters and prizes will be awarded to the top 3.

This is a free workshop and you can sign up for it here.

For those that cannot attend, David Tavakoli will be attending and will distribute notes to anyone interested.
