3. 22. Enhancing the stability of probiotics: Freeze-drying and encapsulation

   Författare :Shuai Bai; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freeze-drying; lyophilization; L.ruteri; Probiotics; Lyoprotectant; Structure; Encapsulating material; Pore size; Material thickness; SEM; Tomography; Storage stability; Amorphous sugars; Glass transition temperature; DSC;

   Sammanfattning : This research dives into the intricate world of freeze-drying, an essential process in pharmaceutical and probiotic industries, to better understand the factors affecting probiotic stability during storage. The process of freeze-drying and the composition of freeze-dried products significantly affect the stability of probiotics, yet factors such as the material’s encapsulation properties remain relatively unexplored, demanding further research.

4. 23. Hot isostatic pressing of ceramics and influence of glass encapsulation

   Författare :Anna-Karin Westman; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Konstruktionsmaterial; Engineering Materials;

   Sammanfattning : Hot isostatic pressing (HIP) is one of the industrial techniques for production of structural ceramics. A high quality of the as-HIPed surface is highly desirable, as it may make it possible to minimise or eliminate costly finishing machining. LÄS MER

5. 24. Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery

   Författare :Jennifer Gilbert; NanoLund: Centre for Nanoscience; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lipid nanoparticles; neutron scattering; SAXS; protein encapsulation; nucleic acid delivery; lipid self-assembly;

   Sammanfattning : Encapsulation in self-assembled lipid structures has been shown to increase the stability of large biomolecules, including proteins and nucleic acids (NAs), which has many potential applications in the food and pharmaceutical industries. In order to fully optimise the encapsulation system for a certain application, however, it is important to understand the effect of the encapsulated biomolecule on the lipid structure and vice versa.

7. 25. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor

   Författare :Mikael Antelius; Göran Stemme; Yogesh B. Gianchandani; KTH; []
   Nyckelord :Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; packaging; vacuum packaging; liquid encapsulation; integration; wire bonding; grating coupler; waveguide; Fabry-Perot resonator;

   Sammanfattning : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. LÄS MER
