1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

2. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. LÄS MER
3. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER
4. SFEER Hydrogen Permeation : Finding a suitable coating for the PA6 liner
Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskapSammanfattning : Water Stuff & Sun are developing a hydrogen battery based on a technology called SFEER’s. The SFEER’s are spherical high-pressure gas storage containers that are the size of a tennis ball. They consist of a carbon fiber-shell that is lined on the inside with a polymer called PA6. LÄS MER
5. Deposition av Black carbon i sjöar efter den stora skogsbranden i Västmanland 2014
Magister-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC); Lunds universitet/Miljövetenskaplig utbildningSammanfattning : Black carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. LÄS MER
