1. Bandgap Engineering of Lead-Free Halide Double Perovskites
Sammanfattning : Lead-free halide double perovskites (HDPs, A2BIBIIIX6) with attractive optical and electronic features are regarded as one of the most promising alternatives to overcome the toxicity and stability issues of lead halide perovskites. They provide a wide range of possible combinations and rich substitutional chemistry with interesting properties for various optoelectronic devices. LÄS MER
2. Combined production of edible mushrooms and biofuels from lignocellulosic residues
Sammanfattning : Forest residues, wood-processing by-products and other lignocellulosic materials are promising renewable resources for bioconversion to advanced biofuels such as cellulosic ethanol. Increased production of biofuels from lignocellulosic materials would allow reducing environmental problems caused by the use of fossil resources while supporting development of bioeconomy. LÄS MER

4. Craft production in the Kingdom of Crystal (Glasriket) and its visual representation : Constructing authenticity in cultural/marketing production
Sammanfattning : Authenticity is a core concept and phenomenon in contemporary marketing, as both marketers and consumers seek the authentic. Individuals, companies, and industries all work to establish and accomplish authenticity for themselves and related stakeholders. LÄS MER
5. Adaptive finite element methods for parameter estimation problems in partial differential equations
Sammanfattning : Physical and chemical phenomena are often described by a system of partial di®erential equations. These equations usually involve unknown parameters, which cannot be measured directly but which can be adjusted to make the model predictions match the observed data. LÄS MER
