Correlations between powder wettability and part color in the High Speed Sintering process
This work has been published in Additive Manufacturing Volume 47, November 2021, 102361, and was a result of our collaboration with Dr. Candice Majewski at the University of Sheffield in the UK. The Morphologi 4 was used to investigate the morphology of different polymers used in High Speed Sintering (HSS), a powder bed fusion Additive Manufacturing (AM) technology. The particle size and shape information obtained using automated image analysis can help to explain behaviors such as powder flow and packing. This analysis formed part of a larger study looking into what properties affect powder wettability/part color in the HSS process, as this can be linked to the mechanical properties of the final part. Through comprehensive characterization, more can be learned about how to optimize powders for these processes.

New application note
Analysis of Catalytic Ink for Proton Exchange Membrane Fuel Cells (PEMFC’s)
Catalytic inks are the key component when balancing cost, performance, and durability of proton exchange membrane fuel cells (PEMFC’s). Particle size and dispersion critically impact the behavior of the ink and resulting performance of the electrode layers, affecting important parameters such as ink viscosity, ionomer distribution and morphology, catalyst utilization, interaction between the catalyst and ionomer, and the homogeneity and continuity of the electrode layer.
X-ray diffraction (XRD), laser diffraction (LD), and dynamic light scattering (DLS) are three characterization techniques each probing a different size regime and, when combined, can provide a comprehensive overview of the particles in the catalytic ink mixture.
Look out for our blog on Fuel cell on our Materials Talks portal on 25th March and our Webinar coming in April.

Featured research area
Metal Organic Frameworks (MOF)
Metal Organic Frameworks (MOFs) are a huge research area, so we’re excited that our research techniques can play a part. Our instruments can be used for detailed crystallographic analysis using X-ray diffraction to track changes under different operating conditions in real time. Or they can be used for physical characterization of manufactured MOF materials, in applications including:
- Fluid separation
- Gas sensors
- Fuel storage
- Water purification
- Drug delivery
At Malvern Panalytical, a dedicated focus group researches and compiles information on solutions for Metal Organic Frameworks (MOF). For instance, you may have seen our recent webinar: Characterization of Metal Organic Frameworks: The building of robust structures. If you missed it, you can watch it on-demand via this link.
A new webinar called "Advanced in-situ experiments on Metal Organic Frameworks" is coming soon - click here to register!

Aeris: Powering the next generation of XRD research
We are very excited about this next stage in the Aeris evolution. Aeris was always designed to be a product that could evolve, and it is evolving into its own class of system. It is compact yet performs like a traditional floor standing system. Aeris occupies a unique position in the XRD market it is future proof and a good investment for any X-ray lab. On 23rd February we launched the Aeris XRD with its new features. If you missed the live launch, you can see a recording here. The launch was to introduce two new Aeris functionalities: X-ray diffraction in transmission and grazing incidence X-ray diffraction. If you want to know more, look at the new brochure and application notes.
