  1. 1. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Avital Cherednik; [2023]
    Keywords : Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Abstract : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. READ MORE

  3. 2. Temperature-dependent waterbinding on potassiumbirnessite : A potential sorbent for atmospheric water harvesting

    University essay from Umeå universitet/Kemiska institutionen

    Author : Hanna Oderstad; [2022]
    Keywords : ;

    Abstract : The nanolayered manganese oxide birnessite (MnO2) is a naturally occurring mineralin soils and sediments. Its ability to capture and store water within its interlayers, andits great solar absorptivity, could be a part of the solution to global water shortage. READ MORE

  4. 3. Pretreatment Methods for Manganese Containing Anode Sludge

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

    Author : Johan Stenman; [2017]
    Keywords : Manganese; Zinc; Lead; Strontium; Reduction; Anode; Sludge; Slime; Metallurgy; Pyrometallurgy; Chamber; Rotary; Furnace; Agglomeration;

    Abstract : This master thesis work examines whether it is possible to separate lead from an electrolytic sludge rich in manganese using pyrometallurgical treatment, and also attempts to determine the optimum process parameters for such a treatment. It also includes a theoretical study of the possible applications for lead and manganese, as well as thermodynamic calculations predicting the behaviour of the material at increasing temperatures.

  5. 4. Use of Manganese Compounds and Microbial Fuel Cells in Wastewater Treatment.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Junli Jiang; [2011]
    Keywords : Digested Sludge; Manganese Compounds; Microbial Fuel Cell; Potassium Permanganate;

    Abstract : Manganese compounds have a high potential for treating wastewater, both for utilizing its oxidation, flocculation ability and catalyst ability in anaerobic nitrification. The promising use of manganese compounds (such as permanganate and manganese dioxide) is regarded as an effective method of treating organic compounds in wastewater from municipal and industrial wastewater.

  6. 5. The application of MnO2 and KMnO4 for persistent organic compounds and COD removals in wastewater treatment process.

    University essay from KTH/VA-teknik, Vatten, Avlopp och Avfall

    Author : Aileen Hendratna; [2011]
    Keywords : COD; KMnO4; MnO2; Oxidation; Organic compounds;

    Abstract : This study examines the use of MnO2 and KMnO4 as strong oxidants to remove specific recalcitrant organic compounds and COD from wastewater. These compounds are deemed as potential and more cost-effective treatment in encountering the challenge to remove Pharmaceuticals and Personal Care Products (PPCPs) and Endocrine Disrupter Compounds (EDCs) in wastewater to meet water reuse standard.
