  1. 1. Effect of powder spray drying on catalyst formulation in tablet form

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Kajsa Wahlgren; [2023]
    Keywords : Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    Abstract : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. READ MORE

  3. 2. Suitability of Spray Dried Powder containing Lipids for Inhalation Formulation based on Fine Particle Fraction and Particle Size Distribution

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Hung Nguyen; [2016]
    Keywords : Fine Particle Fraction: Particle Size Distribution; Drying; Inhalation; DPI; Dry Powder Inhaler; Powder; Inhaler; Spray drying; Lipids; Inhalation Formulation; Lysozyme; Pharmaceutical Technology; läkemedelsteknologi; Technology and Engineering;

    Abstract : The aim of this master thesis is to provide an indication of the suitability, or otherwise usage, of spray-drying for production of powder aimed for inhalation formulation and comparing the characteristics of the product, with and without lipids. Lipids have a proven effect of delaying release of active drug substances in the cardiovascular system and pulmonary systemic delivery has a number of advantages, chiefly among them being bypassing the first pass metabolism.

  4. 3. Development of an Expancel Product through Optimisation of Polymer Composition and the Suspension Stabilising System

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Frida Berggren; [2014]
    Keywords : microspheres; suspension polymerisation; Pickering emulsions; flocculation;

    Abstract : Thermally expandable microspheres are spherical particles around 5-­‐40 µm in size, consisting of a polymeric shell in which a blowing agent has been encapsulated. The microspheres are expanded upon heating, resulting in a particularly low density. Microspheres are therefore suitable to use as light weight filler or as foaming agent. READ MORE

  5. 4. Optimization of Expancel Product and Process : Through the use of Multivariate Planning, Data Analysis and Evaluation.

    University essay from Kemiska institutionen

    Author : Evelina Waltersson; [2012]
    Keywords : ;

    Abstract : The company Expancel produces expandable microspheres. The microspheres are microscopic spherical particles that consist of a polymer shell encapsulating a gas (the blowing agent). Heat causes the particles to expand. READ MORE
