1. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

2. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

3. Identifiering av promotorregionen för Cyt c Id1 samt undersökning av genuttrycket i närvarooch frånvaro av syre
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : In this work, the identification of the promoter for c-cytochromes Cyt c Id-1 in Ideonella dechloratans has been investigated. Additionally, the study examined investigating whether gene expression is affected by the presence and absence of oxygen. LÄS MER
4. First principles investigation of the thermal conductivity of Zr, ZrC, and ZrN
Master-uppsats, KTH/FysikSammanfattning : The thermal conductivity and electrical resistivity of Zr, ZrC, and ZrN were calculated using first-principles density functional theory (DFT) and the Boltzmann transport equation. The electron-phonon scattering was modeled via the self-energy relaxation time approximation (SERTA), and the phonon-phonon scattering via the analogous single-mode relaxation time approximation (SMRTA).

5. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs
Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionenSammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER
