1. 1. Effect of mixing time and mixing rate on the evolution of powderproperties for binary adhesive mixtures

   University essay from Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Author : Noveen Muslih Sadullah; [2024]
   Keywords : Adhesive mixture; mixing time; mixing rate; Budesonide; Lactopress SD;

   Abstract : Dry powder inhalers (DPIs) are often used to deliver drugs to the lungs when treating respiratory diseases. Inhalation powders are often formulated as adhesive mixtures which is the main formulation type used for dry inhalation powders of pharmaceuticals. READ MORE

3. 2. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Viktor Lange; [2023]
   Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

   Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

4. 3. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

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

   Author : Julia Ahlbom; [2023]
   Keywords : Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

   Abstract : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

5. 4. 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

6. 5. Modelling Gas Flow Behaviour in Gas Atomizer

   University essay from KTH/Materialvetenskap

   Author : Aravind Senan Vasanthasenan Reji; [2022]
   Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

   Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.
