  1. 1. Terahertz sensing for pharmaceutical applications

    Författare :Anis Moradikouchi; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Compression analysis as a tool for technical characterization and classification of pharmaceutical powders

    Författare :Josefina Nordström; Göran Alderborn; Maria Strömme; Katharina Picker-Freyer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; compaction; compression; granules; Kawakita; mechanical properties; particles; PAT; pharmaceutical powders; tablets; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : There are today strong incentives for an increased understanding of material properties and manufacturing processes to facilitate the development of new technologies in the pharmaceutical industry. The purpose of this thesis was to suggest methods requiring a low sample amount for characterization of technical properties of powders. LÄS MER

  5. 4. Properties of Ugandan minerals and fireclay refractories

    Författare :John Baptist Kirabira; Stefan Jonsson; Thomas Johansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; kaolin; clay; Ugandan minerals; fireclay; refractory; powders characterization; beneficiation; ceramics; mullite; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Development of products which can be produced from a country’s natural resources is very important as far as the industrialization of a nation and saving foreign exchange is concerned. Presently, industries in Uganda and the other states in the Lake Victoria region import all refractory-related-consumables, as the demand cannot be met locally. LÄS MER

  7. 5. Interfacial and material aspects of powders with relevance to pharmaceutical tableting performance

    Författare :Maria Badal Tejedor; Mark W. Rutland; William Ducker; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; atomic force microscopy; excipients; surface characterization; tableting; milling; amorphisation; Kemi; Chemistry;

    Sammanfattning : Tablets are the most common forms of drug administration. They are convenient to administer and easy to manufacture. However, problems associated with the adhesion of the powders to the tableting tools are common. This phenomenon is known as sticking and even though it has been well documented and studied, it remains poorly understood. LÄS MER
