2. 1. Effect of water on the glass transition and properties of solid-state pharmaceutical formulations

   Author : Ekaterina Bogdanova; Vitaly Kocherbitov; Thomas Rades; Malmö universitet; []
   Keywords : glass transition; glass transition temperature; relaxation; sucrose; trehalose; maltodextrin; lysozyme; unfolding; hydration; solid-stae; sorption calorimetry; Health and society; Hälsa och samhälle;

   Abstract : The aim of this thesis was to increase our knowledge of the glassy state and the glass transition phenomenon and to evaluate the effect of water on the glassy state. To accomplish this, investigations were focused on the amorphous sucrose-water (paper I, II, III), trehalose-water (paper I), maltodextrin-water (paper I), and lysozyme-sucrose-water (paper IV) systems.

4. 2. Utilization of Wild Fruit in Mozambique – Drying of Vangueria infausta (African medlar)

   Author : Eulália Chiau; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vangueria infausta; drying; maltodextrin; sucrose; softener; toughness; solar-assisted pervaporation; aroma; crystallization; water activity;

   Abstract : Vangueria infausta (African medlar) is a wild fruit found in southern and central Mozambique. The ripe fruit has a leathery skin enclosing three to five seeds embedded in a soft pulp that tastes like apple. It plays an important role in the diet of the rural population and has the potential for commercial use. READ MORE

5. 3. Structure Evolution during Phase Separation and Gelation of Biopolymer Mixtures

   Author : Niklas Lorén; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; gelatin maltodextrin; biopolymer mixtures; structure evolution; phase separation; stereology; confocal laser scanning microscopy; image analysis; spinodal decomposition; transmission electron microscopy; gelation;

   Abstract : This thesis focuses on the kinetics of phase separation and gelation in aqueous mixtures of gelatin and maltodextrin. The structure evolution of these mixtures at different length scales was recorded by confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). The microstructure was quantified by image analysis. READ MORE

6. 4. Microstructure of spray dried particles at different scales of drying

   Author : Marine Nuzzo; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure; morphology; confocal Raman microscopy; phase segregation; spray drying;

   Abstract : Spray drying is a preferred method to produce dry powder of thermally sensitive materials such as food and pharmaceuticals. Drying conditions and formulation determine primary properties such as morphology and composition that finally provide functionality such as dissolution, encapsulation and flowability. READ MORE

7. 5. Structure Dynamics and Heterogeneity in Soft Materials Determined by FRAP

   Author : Joel H Hagman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft materials; Fluorescence recovery after photobelaching; Confocal microscopy; Heterogeneity; Structure dynamics;

   Abstract : A common interest in industry today is to be able to control the mass transport inside soft (bio) materials in order to tailor both release and uptake of substances. Most of the materials used are heterogeneous, quite often multiphase or compound materials and often undergo dynamic changes; it is therefore important to have control over the local microstructure in order to tailor the macroscale properties.
