1. 11. Application of electrodes with redox mechanisms for the desalination of water

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Pablo Moreno Cerezo; [2023]
   Keywords : Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

   Abstract : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. READ MORE

4. 13. In situ electrokinetic remediation of soil co-contaminated with trace elements and polycyclic aromatic hydrocarbons

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

   Author : Emma Heidrich; [2023]
   Keywords : polycyclic aromatic hydrocarbons; trace elements; co-contaminated soil; electrokinetic remediation; iron electrodes;

   Abstract : Sites contaminated with polycyclic aromatic hydrocarbons can be simultaneously contaminated with trace elements. Co-contaminated soil is considered a complex problem since inorganic and organic contaminants behave differently and thereby often require different remediation strategies. READ MORE

5. 14. 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

6. 15. Automatic Detection of Structural Deformations in Batteries from Imaging data using Machine Learning : Exploring the potential of different approaches for efficient structural deformation detection

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Maira Khan; [2023]
   Keywords : CT scan; electrode peaks; jelly roll; keypoints; structural deformation; traditional computer vision; deep neural network; CT-skanning; elektrodtoppar; gelérulle; nyckelpunkter; strukturell deformation; Traditionellt datorseende; djupt neuralt nätverk;

   Abstract : The increasing occurrence of structural deformations in the electrodes of the jelly roll has raised quality concerns during battery manufacturing, emphasizing the need to detect them automatically with the advanced techniques. This thesis aims to explore and provide two models based on traditional computer vision (CV) and deep neural network (DNN) techniques using computed tomography (CT) scan images of jelly rolls to ensure that the product is of high quality.
