1. 1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ellen Grace Soroka; [2023]
   Keywords : Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

   Abstract : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. READ MORE

3. 2. Thermal neutron counting and gamma-ray peak identification from fusion reactions, using a Sodern Genie-16 Neutron Generator

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

   Author : Auden Ti; [2022]
   Keywords : Physics and Astronomy;

   Abstract : This thesis work focuses on the categorisation of a Sodern Genie-16 Neutron Generator, at the Nuclear Applications Laboratory, Lund University. To that end, the goals of this work focuses on the re-development of the pre-existing infrastructure surrounding the Sodern Genie-16 Neutron Generator for the purposes of internally irradiating samples, and the subsequent categorisation of the new configuration for extraction of fast neutrons.

4. 3. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Simon Wozny; [2020]
   Keywords : topological insulators; edge states; impurities; density of states; Green s function; Floquet; Physics and Astronomy;

   Abstract : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. READ MORE

5. 4. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jonathan Svedin; [2020]
   Keywords : ;

   Abstract : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. READ MORE

6. 5. Evaluation of a heated inlet to reduce humidity induced error in low-cost particulate matter sensors

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Piotr Czernicki; Mathias Kallmert; [2019]
   Keywords : particulate matter; optical particle counter; relative humidity; low-cost; pm sensor; heated inlet; Technology and Engineering;

   Abstract : The number of low-cost particulate matter (PM) sensors available on the market has increased in recent years. They are affordable, compact and require no maintenance which means they easily can be deployed and utilized for real-time air monitoring. However, the accuracy of low-cost PM sensors has been reported to vary depending on several factors. READ MORE
