21. High-Quality Perovskite Films for Efficient and Stable Light-Emitting Diodes
Sammanfattning : Metal halide perovskites have attracted significant attention for light-emitting applications, because of their excellent properties, such as high photoluminescence quantum yields (PLQYs), good charge mobility, narrow emission bandwidth, readily tunable emission spectra ranging from ultraviolet to near-infrared, and solution processability. Since the first room-temperature perovskite-based light-emitting diodes (PeLEDs) reported in 2014, tremendous efforts have been made to promote the efficiencies of PeLEDs, including theoretical simulation, materials design, and device engineering.

22. The Interaction Between the Chaperonin GroEL and Human Carbonic Anhydrase II : Protein Folding and Stability Studies
Sammanfattning : The presence of GroEL/ES during the refolding of human carbonic anhydrase II was found to increase the yield of active enzyme from approx. 70 to approx. 100%. This chaperone action on the enzyme could be obtained by adding GroEL alone, and the time course in that case was only moderately slower than the spontaneous process. LÄS MER
23. The Finite Element Method for Fractional Order Viscoelasticity and the Stochastic Wave Equation
Sammanfattning : This thesis can be considered as two parts. In the first part a hyperbolic type integro-differential equation with weakly singular kernel is considered, which is a model for dynamic fractional order viscoelasticity. In the second part, the finite element approximation of the linear stochastic wave equation is studied. LÄS MER
24. AKD sizing : dispersion colloidal stability, spreading and sizing with pre-flocculated dispersion
Sammanfattning : Alkylketene dimer, AKD, dispersions are used in the paper industry to obtain paper grades with a hydrophobic character i.e. resistance to sorption of water. AKD is used in neutral to alkaline internal sizing, pH in the interval of 6-9. LÄS MER
25. Glass-forming ternary blends: towards stable Polymer Solar Cells
Sammanfattning : The globally increasing use of electricity goes hand in hand with climate change and the gradual depletion of fossil sources of fuel. To address these challenges renewable sources of energy are in high demand. LÄS MER
