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 (firstname.lastname@example.org) from a GT email address.
The New Raman Renishaw Particle Analysis Software – Targeted Raman Data Collection
Wednesday, September 30th – 2:00pm (EST)
Renishaw’s upcoming Particle Analysis software enables targeted Raman data collection from optical image contrast. This approach ensures data is only collected from the areas of interest, making it a fast and automated method.
In this webinar, we will show how the diverse high performing optical contrast methods of the inVia Raman microscope can be used to quickly, easily, and automatically report particle identities and morphology together. Applied to a diverse range of applications, from microplastics to materials and forensics to pharmaceuticals, see how Particle Analysis can benefit your work.
This webinar will be broadcast in the MCF Lobby in the Marcus Nanotechnology Building.

Surfaces play an important role in almost all aspects of our lives. For example, biosensors that are used to detect and identify diseases are often based on chemical surface modifications. The interaction of small molecules or nanoparticles with surfaces such as lung tissue is also often dictated by surface chemistry. This means that it is critical to know as much as possible about a surface in order to both understand the interactions that occur and to be able to design surfaces that promote successful interactions.
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.
The MCF Staff look forward to welcoming our users back to campus and hope you are all safe and well.

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.
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.
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.

– 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.
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.
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.
Webinar from Malvern PANalytical – XRD Masterclass 1 – Characterization Of Amorphous API
Small molecule drug products often face multiple development challenges, common amongst which are those relating to solubility, stability and manufacturability.
The Developability Classification System (DCS) provides useful guidelines for selecting a formulation technology, based on assessment of the drug’s fundamental properties and dose expectations. APIs which fall under Class 1 (good solubility, good permeability) were discovered and delivered to the market early on.
Nowadays, the majority of small molecule drug candidates are poorly soluble and belong to Class 2 (a & b). For these molecules, solid-form screening and new formulation types are required to create competitive pharmaceutical products.
In the search for more soluble or bioavailable forms, different types of drug formulations are being considered, including nanoparticles, amorphous solid dispersions, co-crystals and drug carrier systems. In this webinar, we’ll focus on amorphous formulations and address the following questions:
• Are amorphous compounds which are obtained in different experimental conditions the same?
• Are they free of nano-crystalline material and are they truly amorphous?
• What are the best ways of quantifying low and high amorphous content?
• How we can we use X-ray diffraction to answer these, and more, questions?
The MCF will be playing this webinar in the MCF Lobby but if you would like to register for this and watch it on your own computer, you can register here.
