  1. 1. 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

  3. 2. Reduction of iron oxide by hydrogen studied using environmental transmission electron microscopy

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : David Wahlqvist; [2020]
    Keywords : Transmission Electron Microscopy; Electron Diffraction; Iron Oxide; Reduction; Iron; Environmental Transmission Electron Microscopy; ETEM; Materials chemistry; Materialkemi; Chemistry;

    Abstract : This thesis aims to explore how the reduction of iron oxide by hydrogen should be explored in an environmental transmission electron microscope (ETEM). This is done by performing a series of reduction attempts in the ETEM at nCHREM, Lund University, and exploring how the ETEM conditions are different from those used commercially. READ MORE

  4. 3. Gamma Radiation-Induced Synthesis of Cerium Oxide Mesocrystals

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Michel Goy; [2019]
    Keywords : ;

    Abstract : Nanoparticles of cerium dioxide was synthesized by gamma irradiation of aqueous solutions containing CeCl3 and CeBr3. ICP-OES was used to determine the precipitation yield. X-ray powder diffraction and transmission electron microscope were used to characterize the products. READ MORE

  5. 4. Primär ciliär dyskinesi som orsak till kronisk lungsjukdom hos hund : en litteraturstudie och fallpresentation

    University essay from SLU/Dept. of Clinical Sciences

    Author : Linda Andersson; [2008]
    Keywords : primär ciliär dyskinesi; mucociliär transport; slemtransport; slem; cilie; flimmerhår; ciliedefekter; hund; PCD; lunginflammation; pneumoni; transmissionselektronmikroskop; biopsi; luftvägssymptom; luftväsinfektioner; behandlingsresistens; sekundär ciliär dyskinesi; immotile-cilia syndrome; Kartagener´s syndrom; situs inversus; bronkiektasi; kronisk; konsolidering; rhinosinusit; bronkit; hosta; unga hundar; otit; fertilitet; lungor; medfödd; genetiska defekter; cilieorörlighet;

    Abstract : Primary ciliary dyskinesia (PCD) is an important but unusual cause of chronic respiratory disease of young dogs. The purpuse of this paper is to study and present internationally publicated papers on PCD in dogs and present three dogs, in which PCD was suspected. PCD has been reported in many dog breeds as well as in people. READ MORE

  6. 5. Diagnostiska metoder för växtvirus i nematodvektorer

    University essay from SLU/Dept. of Crop Science

    Author : Veronika Andersson; Helene Klingberg; [2006]
    Keywords : diagnistisering; nematoder; paratrichodorus; rostringar i potatis; tobacco rattle virus; trichodorus; TRV;

    Abstract : Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting. TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). READ MORE
