1. 16. Indoor and Outdoor Measurements of Particulate Matter with the Low-Cost Optical Sensor OPC-N3

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

   Author : Ellen Grace Soroka; [2020]
   Keywords : Physics and Astronomy;

   Abstract : This paper evaluates the low-cost optical sensor OPC-N3 from Alphasense as a suitable scientific instrument for measuring particulate matter levels in air, both outdoors and in- doors. The time-keeping and data-retrieval was additionally improved by connecting the OPC-N3 to an Arduino microcontroller equipped with a real-time clock (RTC) module and an external SD card. READ MORE

3. 17. The Production of Samarium-Cobalt Nanoparticles Using a Spark Discharge Generator

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

   Author : Timothy Lewis; [2019]
   Keywords : Physics and Astronomy;

   Abstract : In this project I attempt to press custom electrodes from Sm and Co powder using two different pressing tools. I investigate if custom electrodes can generate nanoparticles with tailored properties using a spark discharge generator (SDG). READ MORE

4. 18. 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

5. 19. Influence from long-distance transport, local sources and precipitation on black carbon concentrations at a rural background field station in southern Sweden

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

   Author : Kit Ming Yam; [2019]
   Keywords : Black carbon; black carbon concentrations; Hyltemossa station; Aethalometer; HYSPLIT; long-distance transport; local sources; precipitation; Physics and Astronomy; Earth and Environmental Sciences;

   Abstract : The year 2018 was the first complete year with aerosol observations at the rural background station Hyltemossa in southern Sweden. The aim of this thesis was to analyse and investigate the influence from long-distance transport (LDT) aerosols, local sources and precipitation on the black carbon (BC) mass concentration by utilising the Aethalometer and the HYSPLIT model, which estimated the BC mass concentration ([BC]) and simulated the origin of the LDT air masses to Hyltemossa, respectively.

6. 20. Exposure of zinc oxide nanoparticles on lung epithelium: A comparison between submerged and air-liquid interface cultures

   University essay from Lunds universitet/Ergonomi och aerosolteknologi

   Author : Julia Dobric; [2019]
   Keywords : lung toxicology; nanotoxicology; aerosol; air-liquid interface; ALI; NACIVT; nanoparticles; zinc oxide; Biology and Life Sciences;

   Abstract : Zinc oxide nanoparticles (ZnO NPs) are often used in sunscreen and other cosmetic products with sun protection. They are also candidate to be used for various biological applications such as drug delivery, or in material science in for example solar cells. READ MORE
