1. Stability improvement to a ruthenium catalyst for partial oxidation of methane
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER
2. Återbruk kontra återvinning av litiumjonbatterier
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : I Sverige läggs stort fokus på omställningen till ett hållbart och klimatneutralt samhälle, där avkarbonisering och elektrifiering av transportsektorn anses avgörande för att minska utsläpp av växthusgaser. En storskalig batteriproduktion i Sverige och i Europa medför nya problem kring hållbarhetsaspekter gällande utvinning av råvara som exempelvis litium, kobolt och nickel. LÄS MER
3. Metals for energy storage : For hydrogen and power generation
Master-uppsats, Linköpings universitet/KonstruktionsmaterialSammanfattning : With an increase in energy demand and a transition from conventional fossil-driven energy generation, the world is facing a major challenge. This transition implies more intermittent energy sources whose reliance varies widely with time. To deal with this challenge, energy storage is one part of the solution. LÄS MER
4. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

5. Graphene Based Aqueous Ammonium Dual-Ion Batteries
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER
