1. 1. Learning in physics with simulation : Students’ needs & perceptions of the interaction with Algodoo, and learning in physics

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Seyma Ikra Koyuncu; [2023]
   Keywords : computational thinking; stem; simulations; physics; modelling; digital tools; digital content; computational thinking; stem; simulering; fysik; modellering; digitalt verktyg; digitalt innehåll;

   Abstract : Initiatives to implement computational thinking and science, technology, engineering & modelling into learning processes have been taken by many authorities worldwide, and in Sweden as well. The Swedish government made changes in the high school curriculum in order to develop student’s digital competence including programming which has been in force since June 2018 (Skolverket, 2018).

3. 2. Methods to study device induced aggregation of proteins

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

   Author : Marie Therese von Wowern; [2023]
   Keywords : protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

   Abstract : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. READ MORE

4. 3. Optimising microfluidic preparation of lipid sponge phase nanoparticles for biomolecule encapsulation

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Owais Khalil; [2023]
   Keywords : Sponge phase; lipid nanoparticles; microfluidics; SAXS; cryo-TEM; DLS; chemical engineering; Chemistry;

   Abstract : Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. READ MORE

5. 4. Laser Scattering for Fast Characterization of Cellulose Filaments

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
   Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

   Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

6. 5. Solubility of Wood Xylans, Effect of pH and Concentration

   University essay from KTH/Glykovetenskap

   Author : James Carlsson; [2022]
   Keywords : Xylan; Wood; Solubility; Dynamic Light Scattering; Filtration; Xylan; Trä; Löslighet; Dynamisk ljusspridning; Filtrering;

   Abstract : Lösligheten av xylaner utvunna från trä undersöktes med Dynamisk Ljusspridning i syfte att observera eventuella förändringar i hydrodynamisk volym och ζ-potential. Xylaner extraherade från bok, björk och gran användes, där alkalisk extraherad bok erhölls kommersiellt och prover från björk och gran extraherades i förhand med subkritiskt vatten och alkalisk extraktion.
