1. Structural analysis of HZO thin film and electrode using X-ray diffraction
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER
2. Effective soil organic carbon monitoring in perennial agriculture systems - Sampling protocol development and evaluation
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Perennial agriculture systems are gaining ground as a more sustainable alternative to conventional annual agriculture, partly for their potential to increase the soil organic carbon (SOC) content. Carbon farming is another hot topic for SOC sequestration, as it creates economic incentives for farmers. LÄS MER
3. Characterization of Cu-mineralized carbonate veins in the Alta-Kvænangen Tectonic Window, Norway
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : The Alta-Kvænangen Tectonic Window is part of a regional greenstone belt that formed around 2.3 Ga – 2.0 Ga. The Bergmark anticline in the area has gone through greenschist to amphibolite facies metamorphism and hosts Cu, Co and Au mineralizations in hydrothermal veins, albite felsite and chemical traps.

4. Artificiella torskrev i Hanöbukten: Förstudie
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : Torskpopulationen i Östersjön påverkas negativt av övergödning och överfiske. Man vill därav främja torskpopulationen omkring Hanö genom att placera ut artificiella rev. LÄS MER
5. Loess as an Environmental Proxy for Reconstruction of Palaeoclimate in the High Arctic
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : We are currently speeding towards significant changes in the climate of the earth which, if ignored, will lead to severely altered climatic conditions with serious consequences for several species and ecosystems. The polar regions especially are very sensitive to climate changes, and the changes these regions undergo affect the climate on a global scale. LÄS MER
