Sammanfattning : 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.

Sammanfattning : Gasoline Direct Injection Engines (GDI) for passenger cars currently use fuel injection systems operating at pressures of up to 350 bar. Injection pressures have increased over time, and there is evidence that particulate emissions could be reduced by raising them further, up to 500 bar. LÄS MER
3. Modeling of Spray Formation and Development in OpenFOAM with Application to Diesel and Alcohol Fuels
Sammanfattning : Legislation with reagards to fuel emissions are becoming more stringent. This creates a need for improved engine concepts and fuels. This work is part of an ongoin project to create a concept for a direct injection dual fuel engine, which uses alcohol as main fuel and diesel as a pilot. LÄS MER
Sammanfattning : The formation, ignition, and combustion of fuel sprays are highly complex processes and the available models have various shortcomings. The development and application of multidimensional CFD models, that describe the different phenomena have rapidly increased through the use of commercial and public software (e.g. LÄS MER
5. Pharmaceutical cocrystals : formation mechanisms, solubility behaviour and solid-state properties
Sammanfattning : 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. LÄS MER
