2. 6. Particle Coating in a Wurster Type Bed

   Author : Stina Karlsson; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drying; Particle; Tracking technique; Spouted bed; Fluidisation; Multiphase flow; CFD; Trajectory; Coating; Wurster;

   Abstract : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. READ MORE

4. 7. Pharmaceutical cocrystals : formation mechanisms, solubility behaviour and solid-state properties

   Author : Amjad Alhalaweh; Peter York; Luleå tekniska universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; crystal engineering; cocrystal; formation; solubility; pH; dissolution; surface properties; solid-state properties; Health Science; Hälsovetenskap;

   Abstract : The primary aim of pharmaceutical materials engineering is the successful formulation and process development of pharmaceutical products. The diversity of solid forms available offers attractive opportunities for tailoring material properties. READ MORE

5. 8. Shaping of Food Microstructures

   Author : Lars Hamberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food microstructure; flow; emulsion; carrageenan whey protein isolates; shaping; aggregate; gelatine; suspension; gel formation; particle; Fourier shape description; shape; shape measurements;

   Abstract : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.

6. 9. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass

   Author : Hanbing He; Marcus Öhman; Kent Davidsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layer formation; bed particle; woody biomass; quartz; K-feldspar; olivine; bed agglomeration; deposition; fluidized bed; combustion; gasification; Energiteknik; Energy Engineering;

   Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

7. 10. Entrained flow studies on biomass fuel powder conversion and ash formation

   Author : Per Holmgren; Markus Broström; Kentaro Umeki; Rainer Backman; Kevin Whitty; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermochemical biomass conversion; particle image velocimetry; gasification; entrained flow reactor; ash transformation; equilibrium calculations; slag formation;

   Abstract : Reducing the global dependence on fossil fuels is of paramount importance in tackling the environmental challenges we face, not only tomorrow, but already today. Biomass offers a renewable supply of CO2-neutral raw material that can be converted into many different forms of fuels and valuable chemicals, making it a prime candidate for the technologies of tomorrow.
