  1. 1. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    University essay from KTH/Kemi

    Author : Josephine Berg; [2021]
    Keywords : jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Abstract : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. READ MORE

  3. 2. Evolution and Differentiation of Large Icy Moons

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Piia Tomberg; [2021]

    Abstract : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. READ MORE

  4. 3. Advanced rear contact design for CIGS solar cells

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

    Author : Jorge Alexandre De Abreu Mafalda; [2019]
    Keywords : CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Abstract : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. READ MORE

  5. 4. Investigation of soil related potential for sustainable growth and development of Oil Palm (Elaeis quineensis Jacq) in Nigeria

    University essay from SLU/Dept. of Soil and Environment
