The specific surface area of a material, often referred to as BET surface area, is an important parameter throughout all kinds of industries. Whether it is in the field of adsorbents, additive manufacturing, pharmaceuticals, or catalyst research, this parameter helps in quality control, to optimize processes, and improve material performance. Even though the determination…
Zeolites are microporous aluminosilicates that are commonly used as catalysts and adsorbents in many applications. Acid site characterization of a zeolite is crucial to gauge and optimize for a wide variety of different catalytic activities. In this case study the effect of different SiO2/Al2O3 ratios on acidity of ZSM-5 and the effect of heat…
This webinar presents a generalized approach to modeling the pore size distribution which has been developed to determine the complete distribution of macro-, meso-, and micro-pores. Rather than using a fragmented approach of simple overlays from individual techniques, the Unified Method provides a full pore size distribution and improved estimate of total pore volume…
The freeze-drying procedure is a common technique used in the food industry to dehydrate organic compounds. The technique, also known as lyophilization or cryodesiccation, is a method of food preservation by removing water content. Understanding the porous structure of freeze-dried organic products is complex and requires a combination of various analytical techniques. The detection…
Many studies have been presented recently concerning the powder flow or the particle characteristics of feedstocks used in Additive Manufacturing applications. Analyses of fresh powder, powder that has been used for several build cycles, and blends of these two have been characterized. In this presentation, both bulk powder rheology and characteristics of particles that…
Lithium-ion (Li-ion) batteries are an advanced technology that will play a key role in the trend toward renewable and sustainable industrial electrification solutions. The FT4 Powder Rheometer® is a versatile instrument that can be used in both wet and solid li-ion battery electrode manufacturing processes. The comprehensive powder flow analysis provided can help improve…
A critical attribute that contributes to the quality of a manufacturing process is the density of the powdered or solid material. Density gives information about the amount of material in a given volume which can offer a prediction of how the powdered material will pack. Density also gives information on the amount of hollow…
A reliable method to design site-isolated metal catalysts is through the synthesis of intermetallic bulk compounds where a small number of active atoms are isolated in an inert matrix of a second metal. Unlike alloys, intermetallics have long range periodic atomic order and are more likely resistant to surface segregation effects making them an…
Many powders have the potential to cake during storage. As the strength of particle-particle interactions increases, especially via mechanisms involving moisture, the flow characteristics of the material are compromised, detrimentally impacting performance and value. Caking may be preventable or easily addressed through the adoption of well-defined protocols, for example, storing the material in a…
Most current climate models suggest that limiting warming to less than 2°C will require large scale deployment of negative emissions technologies (NETs). NETs, which remove CO2 from the atmosphere, are projected to be needed at a scale of 10 Gt/y by 2050, yet today, virtually none of been deployed. NETs may be natural or…
