  1. 1. Designing Mesoporous Test Sticks for Measuring PFAS Concentrations in Water

    University essay from Linköpings universitet/Nanostrukturerade material

    Author : Amanda Hillås; [2022]
    Keywords : Mesoporous material; PFAS; PFOA; PFOS; Rose Bengal; adsorption;

    Abstract : Water contamination through substances called per- and polyfluoroalkyl substances (PFAS) is a worldwide problem. Being able to measure the concentrations of PFAS in water is a first step towards beating this contamination. One alternative is to use a field test kit instead of extensive lab equipment to monitor the contaminated areas. READ MORE

  3. 2. Inhibition Kinetics of Hydrogenation of Phenanthrene

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Johannes Johansson; [2019]
    Keywords : Catalytic hydrotreating; Phenanthrene; Inhibition kinetics; Model development; Nonlinear regression;

    Abstract : In this thesis work the hydrogenation kinetics of phenanthrene inhibited by the basic nitrogen compound acridine and the non-basic carbazole was investigated. Based on a transient reactor model a steady state plug flow model was developed and kinetic parameters were estimated through nonlinear regression to experimental data. READ MORE

  4. 3. Fluid motion analysis in the cryogenic tanks of the upperstage of Ariane 5 during the ascent phase

    University essay from KTH/Aerodynamik

    Author : Christophe Montsarrat; [2017]
    Keywords : ;

    Abstract : In the frame of the improvement of the performances for Ariane 5, an analysis iscarried out to explain the pressure drop observed in the ascent phase of some flights inthe liquid hydrogen (LH2) tank of the upper stage. This stage is mainly idle until therocket is out of the atmosphere but is submitted to important excitation throughoutthe ascent phase in the atmosphere. READ MORE

  6. 5. Organogena jordar : hur man kan minska markytesänkning och växthusgasemission

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Fredrik Karlsson; [2017]
    Keywords : organogena jordar; markytesänkning; mulljord; emission;

    Abstract : Odlade organogena jordar motsvarar idag ca 7 % av den svenska jordbruksmarken. Genom dränering av tidigare våtmarker har de gått från att ackumulera kol till att släppa ut kol i form av koldioxid. READ MORE
