1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy
Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER
2. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor
Kandidat-uppsats, Linköpings universitet/KemiSammanfattning : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. LÄS MER
3. Tillväxt av parkslide (Reynoutria japonica Houtt.) vid varierande tillgång på vatten : En experimentell studie av sticklingar och rhizomer
Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Invasiva främmande arter (IFA) har negativa effekter på biologisk mångfald och inhemska ekosystem. Parkslide (Reynoutria japonica Houtt.) är en svårutrotad IFA som har fått stor spridning i delar av Europa, och även i södra och mellersta Sverige, framförallt i kustområden. LÄS MER
4. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D
Master-uppsats, Lunds universitet/MaterialteknikSammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER
5. Research on the Hydrothermal Conversion of Xylose Catalysed by CO2-H2O into Furfural
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Agricultural waste treatment and carbon dioxide emissions from fossil fuel combustion have been critical challenges for sustainable development. This work is part of a study on converting straw into biofuels, which involves using xylose as the material, carbon dioxide (CO2) as the catalyst, and water (H2O) and Gamma-Valerolactone (GVL) as the solvent to produce furfural through hydrothermal conversion.
