  1. 1. 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

  2. 2. Characterization of Mitilysin Pores by Cryo-electron Microscopy

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Vladimir Novakovic; [2023]
    Keywords : Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

    Abstract : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. READ MORE

  3. 3. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

    University essay from KTH/Tillämpad fysik

    Author : Elaheh Aghajafari; [2023]
    Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

    Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

  4. 4. In-situ Growth of Sn-seeded GaAs and GaSb Nanowire Heterostructures

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Azemina Kraina; [2023]
    Keywords : nanowire; heterostructure; ETEM; MOCVD; TEM; in-situ; Sn; GaAs; GaSb; materials chemistry; Technology and Engineering; Chemistry;

    Abstract : One of the ways to utilize III-V nanowires, is to make use of the possibility to combine materials and create heterostructures which allows for creating material combinations with new properties. A special interest can be taken into Sb-containing nanowires due to the high electron mobility, however there has been reported difficulties with switching to other materials because of a 'memory effect' where Sb lingers in the system and nanowire.

  5. 5. 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
