Best Practice for BET Surface Area

  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…

Unified Approach to Understanding Porous Materials

  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…

Porosity and Density Characterization of Freeze-Dried Organic Products: Case Study of Instant Coffee

  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…

Intermetallics with Isolated Metal Ensembles Define Active Site Requirements and Dictate Catalytic Selectivity during Semi-hydrogenation

  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…
