1. Structuring porous adsorbents and composites for gas separation and odor removal
Sammanfattning : Porous zeolite, carbon and aluminophosphate powders have been colloidally assembled and post-processed in the form of monoliths, flexible free standing films and coatings for gas separation and odor removal. Zeolite 13X monoliths with macroporosites up to 50 vol% and a high CO2 uptake were prepared by colloidal processing and sacrificial templating. LÄS MER
2. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling
Sammanfattning : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. LÄS MER
3. 3D Electron Microscopy Methods and Applications : Structures from Atomic Scale to Mesoscale
Sammanfattning : The crystal structure determines the physical properties of a material. The structure can be analysed at different levels, from atomic level, mesoscale level, all the way up to the macroscale level. LÄS MER
4. Structured molecular sieves : synthesis, modification and characterization
Sammanfattning : The work presented concerns synthesis of structured molecular sieves. The preparation procedure is based on the use of ion exchange resins as macrotemplates. Macroporous cation or anion exchange resin types were used depending on the molecular sieve type to be synthesized. LÄS MER
