2. 1. Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years

   Author : Rixt de Jong; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Holocene climate; south-west Sweden; aeolian activity; humidity changes; vegetation development; REVEALS vegetation modelling; atmospheric circulation changes; peat sediments;

   Abstract : This thesis aims to reconstruct and explain variations in storm activity, humidity, vegetation composition and land cover in south-west Sweden during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. READ MORE

4. 2. Molecular and isotopic characterization of terrestrial organic carbon released to (sub-)Arctic coastal waters

   Author : Jorien Elisabeth Vonk; Örjan Gustafsson; Jason Neff; Stockholms universitet; []
   Keywords : organic carbon; terrestrial biomarkers; radiocarbon; particulate organic carbon; sediments; sphagnum; Arctic; Bothnian Bay; East Siberian Sea; Kalix River; Kolyma River; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Arctic soils store half of the global soil organic carbon (OC) pool and twice as much C as is currently present in the atmosphere. A considerable part of these carbon pools are stored in permafrost. READ MORE

5. 3. Anti-Ageing Strategies : How to avoid failure in sodium-ion batteries

   Author : Le Anh Ma; Reza Younesi; Daniel Brandell; Laurent Duda; Philipp Adelhelm; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries; manganese-based cathodes; solid electrolyte interphase; ageing mechanism; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

   Abstract : In order to move away from fossil fuels, batteries are one of the most important technologies to store energy from renewable sources. The rapid demands of battery applications put pressure on supply chains of raw materials, such as lithium, nickel, copper, aluminium and cobalt. READ MORE

6. 4. Atomistic Modelling of Materials for Clean Energy Applications : hydrogen generation, hydrogen storage, and Li-ion battery

   Author : Zhao Qian; Rajeev Ahuja; Börje Johansson; Antonio Ferreira da Silva; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Renewable energy; Materials science; Hydrogen production; Hydrogen storage; Li-ion battery; Density functional theory; SRA - Energy; SRA - Energi; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

   Abstract : In this thesis, a number of clean-energy materials for hydrogen generation, hydrogen storage, and Li-ion battery energy storage applications have been investigated through state-of-the-art density functional theory.As an alternative fuel, hydrogen has been regarded as one of the promising clean energies with the advantage of abundance (generated through water splitting) and pollution-free emission if used in fuel cell systems.

7. 5. Transport, degradation and burial of organic matter released from permafrost to the East Siberian Arctic Shelf

   Author : Lisa-Marie Bröder; Örjan Gustafsson; Tommaso Tesi; Elizabeth Canuel; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; organic carbon; marine sediments; East Siberian Sea; Laptev Sea; cross-shelf transport; degradation rate constants; carbon isotopes; terrestrial biomarkers; HMW wax lipids; lignin phenols; compound-specific radiocarbon analysis; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Permafrost soils in the Arctic store large quantities of organic matter, roughly twice the amount of carbon that was present in the atmosphere before the industrial revolution. This freeze-locked carbon pool is susceptible to thawing caused by amplified global warming at high latitudes. READ MORE
