1. 21. Evaluation of two-stage GAC filtration for PFAS reduction in drinking water

   University essay from SLU/Department of Molecular Sciences

   Author : Julia Söderberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

   Abstract : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. READ MORE

3. 22. LoRa Based Moisture Sensing System

   University essay from Uppsala universitet/Signaler och system

   Author : Rasha Badran; [2023]
   Keywords : LoRa; moisture sensor; capacitive sensor;

   Abstract : Water is an important parameter for crop growth, and the information about the moisture content in soil at different depths is very useful for farmers to determine the best time to water the soil and to irrigate farmland so as to maximize their yield. This thesis project aims to develop a prototype of a multi-depth moisture sensor probe that is part of a large sensing system used in agriculture. READ MORE

4. 23. Suppression of Li-ion Battery Fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Linfan Cai; [2023]
   Keywords : Lithium-ion Battery; Fire Suppression System; Extinguishing Agent; Thermal Runaway; Battery Energy Storage System; Electric Vehicle; Technology and Engineering;

   Abstract : This thesis presents a systematic literature review of fixed fire suppression systems and extinguishing agents for lithium-ion battery (LIB) fires. The review identifies 85 relevant sources published between 2013 and March 2023, and categorises different research experiments into cell-level, module-level, electric vehicle (EV) pack-level, battery energy storage system (BESS) rack-level and warehouse storage experiments, according to LIB configurations.

5. 24. The Effect on Mechanical Properties in Biochar Replaced Cement & Aggregate in Concrete Before and After Fire Exposure

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

   Author : Felix Hansen; Mathias Berglund; [2023]
   Keywords : Biochar; Concrete; Sintering; Fire; Mechanical properties; Sustainability; Cement; Biochar in concrete; Building industry; Concrete exposed to fire.; Biokol; Betong; Sintring; Eld; Mekaniska egenskaper; Hållbarhet; Cement; Biokol i betong; Byggindustri; Brandexponerad betong.;

   Abstract : Concrete is good as a construction material regarding fire and its properties regarding strength. However, the concrete expands and cracks due to fire resulting in structural damage. According to the literature the concrete usually loses its strength during and after fire exposure due to themechanical and physical changes. READ MORE

6. 25. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

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

   Author : Ulrike Küst; [2023]
   Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

   Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE
