1. Structural analysis of HZO thin film and electrode using X-ray diffraction
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : 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. READ MORE

2. Emission factors and methods used in climate impact assessments of energy use in Swedish heated buildings - Assessing district heating and electricity as energy source
University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesignAbstract : When the property- and building industry moves towards new solutions targeting reduced climate impact, this puts pressure on the building owners and companies to calculate the climate impact of buildings. It may seem easy, but there are various methods and guidelines to navigate around. READ MORE

4. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells
University essay from Lunds universitet/Centrum för analys och syntesAbstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

5. Accelerating the Green Transition - Investigating the Feasibility of E-Fuel Production Connected to a CHP Plant
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The overall purpose of this thesis is to investigate the feasibility of producing electrofuels from CO2 and H2 in connection to a CHP plant equipped with carbon capture technology. This is done by investigating the production of e-methane, e-methanol and e-kerosene from captured CO2 and H2 produced from electrolysis. READ MORE
