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

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.

Webinar: Cold and Colder, Nanoindentation Down to -120°C

This webinar will be presented in the lobby of the MCF in the Marcus Building on Thursday, April 19th


8AM PDT | 11AM EDT | 15:00 GMT

Materials behavior is often dominated by highly localized phenomena, and the ability to probe these local properties for engineering devices is critical. Often these devices are operating in environments with large differences in temperature and pressure: from the high vacuum and cold of space to the high temperature and high pressure inside a deep-water oil well. This webinar will focus on testing from room temperature down to -100°C on a variety of materials classes;

Metals/Composites:
A fundamental study in a low carbon, 1018, steel is presented. This material is non-exotic, but plays a large role in the nuts and bolts of everyday life. 1018 steel is a two phase steel, containing both ferrite and pearlite phases that are easy to distinguish both via in contact SPM and high speed mapping of the steel, with the high C pearlite being much harder than the ferrite. This material also exhibits a ductile to brittle temperature transition at -5°C via Charpy impact testing. However, when the individual phases can be examined separately, the DBTT can be described to each phase. Besides a rapid increase in hardness, as the ability to cross-slip decreases, there is a change in the behavior of the load-displacement curve from smooth to heavily serrated flow dominated by pop-in behavior in the ferrite phase.

Polymer Films:
Determining the glass transition temperature of polymer films can be difficult due to specimen geometry that does not conform to typical macroscale test algorithms. Here, determination of polymer thin films is demonstrated by varying both temperature and frequency using a nanoscale equivalent test, nanoDMA III. Control of operating conditions below room temperature here is critical to understanding materials performance in a cold weather environment.

Webinar: Nanoscale Tribology – Understanding Mechanical and Tribological Surface Modification in Lubricated Contacts

Webinar on Nanoscale Tribology: Understanding Mechanical and Tribological Surface Modification in Lubricated Contacts

This webinar will be on display in the lobby of the MCF in the Marcus Building at 11:00AM on March 15th.

Tribological properties play a critical role in the proper function, longevity, and energy efficiency of mechanical systems. The ability to quantitatively characterize surface interactions over the nanoscale and microscale provides a new understanding of how to better control friction and wear behavior in bulk material systems and thin tribological films.

In this webinar we will discuss the theory and applications of tribological and mechanical characterization over the nanometer to micrometer length scales. Practical applications will be presented relating to the field of lubricated sliding materials found in pistons, bearings, rubber gaskets, and other interacting components used in engines and power trains. We will demonstrate how nanoscale indentation and scratch testing provides powerful information for studying localized changes due to tribological processes and how these complimentary techniques provide greater insight to optimize tribological performance.
