Predicting crystal growth via a unified kinetic three-dimensional partition model

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1467321

A general simulation approach that can replicate, and in theory predict, the growth of a wide range of crystal types, including porous, molecular and ionic crystals, is demonstrated....

Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1354948

When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading to the formation of Si-islands/aggregates with a concomitant loss of Brønsted...

In-Situ Atomic Force Microscopy Study of the Dissolution of Nanoporous SAPO-34 and SAPO-18

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1312554

In-situ atomic force microscopy has been used to investigate the dissolution behavior of industrially relevant silicoaluminophosphate catalysts SAPO-34 and SAPO-18. Spiral growth is prevalent on these materials and it is common for the spirals to be composites of multiple dislocation sources. The sp...

CHA/AEI intergrowth materials as catalysts for the Methanol-to-Olefins process

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1280612

A series of SAPO-34/SAPO-18 intergrowth materials were prepared with a range of silicon content from 0.5 to 7.0%, where low levels of silicon resulted in SAPO-18 and higher levels resulted in CHA/AEI intergrowths. These materials were tested for their performance in the Methanol-to-Olefins reaction....

Nanoporous Intergrowths: How Crystal Growth Dictates Phase Composition and Hierarchical Structure in the CHA/AEI System

https://www.sintef.no/en/publications/publication/?pubid=CRIStin+1260838

Some of the most important nanoporous materials that are used for industrial applications are formed as intergrowths between structurally related phases. Further, the specific properties and functions are often strongly related to the nature of these intergrowths. By their nature such structures are...
