2. 1. Cold compaction of composite powders

   Author : Olle Skrinjar; Per-Lennart Larsson; Alan Cocks; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; micromechanical modelling; composite powders; descrete element method; Engineering mechanics; Teknisk mekanik;

   Abstract : Powder compaction is a production method commonly used in the manufacturing industry today. In order to minimize costly experiments and to optimize serial production of details several methods to analyze the powder compaction process are developed and used. READ MORE

4. 2. Preparation of Pharmaceutical Powders using Supercritical Fluid Technology : Pharmaceutical Applications and Physicochemical Characterisation of Powders

   Author : Sitaram Velaga; Johan Carlfors; Kristiina Järvinen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Supercritical fluid; Gas Anti-Solvent; SEDS; Crystallisation; Particle design; Polymorphs; Dry powder inhalation; Solid-state behaviour; Therapeutic proteins; Precipitation; Stability; Recombinant human growth hormone hGH ; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

   Abstract : The main aim of the thesis was to explore the potential of supercritical fluid (SF) techniques in the field of drug delivery. In particular, the relatively recently developed solution-enhanced dispersion by supercritical fluids (SEDS) technology has been employed in the preparation of particles/powders. READ MORE

5. 3. Hot working of powders : procedure and products

   Author : Björn Arén; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

   Abstract : This dissertation can be divided into two main parts. The first deals with the hot working conditions of mild steels in powder forging, the second with the deformation behaviour of powder forged products; both monolithic and compound parts are studied. READ MORE

6. 4. Terahertz sensing for pharmaceutical applications

   Author : Anis Moradikouchi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frequency domain spectroscopy; terahertz sensing; multivariate analysis; Pharmaceutical; radar; porosity; powders; API content; tablets; powder flow characterization; tablet density;

   Abstract : Pharmaceutical tablets are manufactured through the compaction of powder blends or granules in batch or continuous processes. In continuous manufacturing, real-time assurance of quality becomes essential to ensure that the final product meets the quality standards approved by manufacturers and regulatory authorities.

7. 5. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts

   Author : Jessica Elversson; Göran Alderborn; Anna Millqvist-Fureby; Lars Hovgaard; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Spray drying; Particle formation; Density; Protein formulation; Encapsulation; Coating; Competitive adsorption; Polymer; ESCA; AFM; FTIR; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

   Abstract : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.
