  1. 21. Formulation and characterization of lipid-based nanocarriers for the delivery of antimicrobial peptide

    University essay from KTH/Proteinvetenskap

    Author : Srijani Saha; [2022]
    Keywords : AP114; Antimicrobial peptide AMP ; Nanostructured lipid carriers NLC ; Liposomes; Dynamic light scattering DLS ; Hydrodynamic size distribution; Zeta potential; Entrapment efficiency EE ; Release study;

    Abstract : Bakterier som är resistenta mot antibiotika har de senaste åren blivit ett stort hot mot mänskligheten. Att utveckla nya antibiotikaläkemedel är väldigt tidskrävande samt kommer med en dyr prislapp. READ MORE

  2. 22. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    University essay from KTH/Materialvetenskap

    Author : Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Keywords : ;

    Abstract : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. READ MORE

  3. 23. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

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

    Author : Alejandra Fernandez Castaneda; [2022]
    Keywords : Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Abstract : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  4. 24. Comparing different methods of measuring particle size for pharmaceutical excipients

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

    Author : Jiawen Wang; [2022]
    Keywords : particle size; comparison; Malvern analysis; Qicpic analysis; Pharmaceutical technology; Technology and Engineering;

    Abstract : In pharmaceutical science, particle size is one of the most fundamental parameters of materials, but different particle-sizing analysis methods lack a uniform standard for measuring irregular particle size, making it difficult to compare the accuracy and applicability of different particle-sizing analysis methods. Experiments on excipients used in pharmaceuticals are carried out in this paper by laser diffraction analysis (Malvern wet and dry), dynamic image analysis (Qicpic), and microscopic methods (Qicpic, SEM, and light microscopy) to determine the applicability and limitations of each method, as well as to clarify their advantages and disadvantages.

  5. 25. Development of MALS methods for exosome size analysis

    University essay from KTH/Kemi

    Author : Terese Andersson; [2022]
    Keywords : Exosomes; Multiangle light scattering; MALS; extracellular vesicles; Exosomer; Multiangle light scattering; MALS; extracellulara vesiklar;

    Abstract : Exosomer är extracellulära vesiklar i nanostorlek som frigörs från cellerna till den extracellulära matrisen. Exosomer är laddade med nukleinsyror, proteiner, och lipider, och fungerar som kommunikatorer mellan celler. Det har gjort dem mycket attraktiva for forskning inom terapi, diagnostik och transport av läkemedel. READ MORE
