Making connections – A study of electrode materials for single CsPbBr3 nanowire devices

Vår moderna värld är på många sätt och vis byggda på datorer, som möjliggör allt från kommunikation, ekonomiska transaktioner och underhållning. Dessa datorer bygger i sin tur på transistorer, halvledarkomponenterna som möjliggör de otaliga beräkningar per sekund som en modern dator utför. Våra vardagliga interaktioner med dessa datorer och mycket annat bygger dock på en annan sorts komponenter, nThe last decade and a half has seen intense research efforts into metal-halide perovskite (MHP) materials, as researchers have come to appreciate their excellent photo-electrical properties such as good radiative recombination rates and light absorption. As part of these efforts MHP-devices of different morphologies have been developed. Notably the enhanced nanophotonic effects of nanowire (NW) mo

"Sveriges vackraste baksida" - Skuggdestinationers möjligheter och utmaningar, en fallstudie om Kallbygden

Skuggdestinationer är platser som är belägna nära större etablerade turistorter med starka varumärken. Platser som befinner sig i periferin ställs inför utmaningar att synas och dra till sig besökare då många väljer att åka till de etablerade destinationerna. Efter pandemin uppstod en ökad vilja att besöka landsbygdsområden för att vara närmare naturen och få uppleva ett lugnare tempo. Intresset f

Kurslyft eller kursfall?

Studien undersöker den kortsiktiga aktiemarknadsreaktionen när amerikanska företag offentliggör förvärv i EU och vilka faktorer som förklarar förvärvarens kumulativa abnorma avkastning (CAR).

An introduction to quasi-conformal mappings

This thesis introduces the theory of quasiconformal mappings on the plane. We give three different definitions of quasiconformal mappings: Differentiable quasiconformal map and two geometric definitions, one based on boundedness of the modulus of quadrilaterals and the other on ring domains. We also showcase when these definitions are equivalent. Then we prove that the geometric definition for qua

Comparative Analysis and Optimization of SFC-MS/MS and LC-MS/MS for Pesticide Residue Analysis in Bumblebee Samples

This study focuses on the chromatographic analysis of neonicotinoid pesticides in bumblebee samples. Analyzing these residues presents significant challenges due to the complex biological matrix and the critical need for high detectability to meet regulatory limits. Furthermore, many conventional chromatographic methods are often time-consuming and rely on substantial volumes of hazardous organic

Cake Layer Formation and Cake Filtration of Soft Particles : Numerical Simulation of Flow in Porous Media: Permeability of Micropillar Arrays in a Microfluidic Membrane

Membrane fouling, particularly by soft, deformable particles, is a significant challenge in microfiltration (MF) processes, leading to reduced efficiency and increased operational costs. This thesis investigates the formation of filter cake layers by numerically simulating fluid flow through microfluidic membranes designed with random, non-overlapping cylindrical micropillar arrays. The study aims

”Är vi värst så är vi starkast, då har vi mest makt” Hederskultur i svenska kriminella gäng och dess påverkan på kvinnor

De svenska kriminella gängen beskrivs idag drivas av jakten på status och det talas om en heder bland gängmedlemmar som upprätthålls genom våld och kontroll, särskilt av kvinnor. Därmed har denna studie i syfte att undersöka hur hedersrelaterade normer tar sig uttryck i svenska gängmiljöer, samt vilka könsspecifika konsekvenser som detta medför. Två semistrukturerade intervjuer med två svenska ide“If we’re the worst, we’re the strongest. Then we have the most power." Honour culture within Swedish criminal gangs and its impact on women Swedish criminal gangs today are driven by the pursuit of status, and there is talk of an internal honour among gang members that is maintained though violence and control, particularly of women. This study thus aims to investigate how honour-related no

Exploring top pair decay with the ATLAS Open Data

This thesis aims to reproduce the ATLAS detector measurements of the top quark mass, which is done by removing background events in the ATLAS detector dataset that has been extracted from the ATLAS Open Data (AOD). Understanding how it is produced and decayed, and how it can be seen in the detector. The coding for this project was done in ROOT via C++. We used simulations and a theoretical backgro

Labor and degrowth: Understanding overlaps and divergences of degrowth and union political policies

Recognizing that the labor movement is under-theorized as a political subject in degrowth literature, this thesis investigates potentials for alignment between degrowth and the Swedish labor movement through a focus on policies. It hypothesized that the two, from a policy perspective, may hold positions that could mutually reinforce each other. Departing from 14 policies proposed jointly in degrow
