1. 1. Efficiency of sustainable urban drainage systems during flash floods

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Snærós Axelsdóttir; [2022]
   Keywords : Bioretention Cell; Rain Garden; Infiltration Trench; Green Roof; Permeable Pavement; Stormwater runoff; Storm Water Management Model;

   Abstract : As the world’s population is migrating more into urban areas, landcover changes follow. Natural pervious areas are being converted to impervious areas, which when subjected to rain generates more stormwater runoff. READ MORE

3. 2. Analysis of simulation of lightning in a cold-based convective storm

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Linus Karlsson; [2018]
   Keywords : lightning; lightning flash; lightning discharge; cold-based convective cloud; convective cloud; microphysics; microphysical specie; cloud electrification; storm cell; convective storm cell; severe weather; Physics and Astronomy;

   Abstract : In this paper a simulation of a convective cell of a thunderstorm system observed 19th of June 2000 during the Severe Thunderstorm Electrification and Precipitation Study (STEPS) field campaign is being analysed. The storm system has been simulated with an Aerosol-Cloud model and the analysis is based on the output data. READ MORE

4. 3. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Jonatan Fast; [2017]
   Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

   Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.
