  1. 1. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Arvid Sandberg; [2023]
    Keywords : Dual ion batteries; materials science; chemistry; organic polymer;

    Abstract : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. READ MORE

  3. 2. 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. 3. Activity and stability of urease enzyme molecules for on-site urea measurement in milk

    University essay from Linköpings universitet/Sensor- och aktuatorsystem

    Author : Emma Valtersson; [2022]
    Keywords : Kemisk biologi; urea i mjölk; biosensor;

    Abstract : The nitrogenous metabolite urea is an important biomarker that indicates cows’ nutritional intake. Today, determining the urea concentration from milk samples requires analysis techniques in a lab which is time-consuming and expensive. READ MORE

  5. 4. Investigation of stability in high salt polymer electrolytes for sodium batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Fengnan Yuan; [2022]
    Keywords : ;

    Abstract : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

  6. 5. Electrical wiring of Shewanella oneidensis MR-1 with osmium polymers of different redox potentials

    University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Beräkningskemi

    Author : Laleh Tavakoli; [2021]
    Keywords : Analytical Chemistry; Bio-Analytical Chemistry; Electrochemistry; Bacteria; Osmium redox polymers; Shewanella Oneidensis MR-1; electrode; Microbial electrosynthesis; Electron transfer; Chemistry;

    Abstract : The results of studies have shown that the several applications such as microbial electrochemical system (MES), bio-electrochemical systems (BESs) and production of beneficial chemicals are due to electrochemical connection among electrodes and microorganisms. The following two factors are important in choosing the microbe mediated electrochemical biosensors: I) Binding of bacterial cells on the electrode, II) Efficient electron transfer (EET) between the electrode and the cells by a mediator.
