1. 21. 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.

3. 22. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Aidas Urbonavicius; [2023]
   Keywords : ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

   Abstract : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. READ MORE

4. 23. Effects of mixed surfactant system on chemical and physical stability of human growth hormone

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

   Author : Karnsinee Viriyayudhakorn; [2023]
   Keywords : human growth hormone; surfactant; refolding; protein stability; physical degradation; chemical degradation; pharmaceutical technology; Technology and Engineering;

   Abstract : In protein formulation, addition of surfactants is commonly executed to enhance product stability and shelf-life. The reason is that surfactants can protect proteins against surface-induced aggregation. However, the interaction between surfactant and protein depends on the type of surfactant used. READ MORE

5. 24. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

   University essay from KTH/Tillämpad fysik

   Author : Jonathan Karlsson; [2023]
   Keywords : Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

   Abstract : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.
