  1. 1. Apparent density for water atomized low-carbon steel powder

    University essay from KTH/Materialvetenskap

    Author : Simon Lindström; [2023]
    Keywords : ;

    Abstract : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. READ MORE

  3. 2. Filtration of oil-in-water nanoemulsions for potential adjuvant development applications

    University essay from KTH/Kemiteknik

    Author : Emilie Degeneve; [2023]
    Keywords : Filtration of oil-in-water nanoemulsions for potential adjuvant development applications; Vaccin; adjuvans; nanoemulsion; ytaktiva ämnen; filtrering;

    Abstract : I den här studien undersöktes innovativa sammansättningar för produktion av vaccinadjuvans. Syftet var att stabilisera nanoemulsioner av olja i vatten, med hjälp av squalenolja (som används inom läkemedelsindustrin), med olika ytaktiva ämnen och att testa filtrerbarheten hos dessa nanoemulsioner.

  4. 3. Magnetic Ionic Liquids in Solutions and Emulsions

    University essay from KTH/Materialvetenskap

    Author : Simon Bruno; [2022]
    Keywords : ionic liquids; microemulsion; magnetic response; surfactant; co-surfactant; imidazolium cation; polarity; chain length effect; joniska vätskor; mikroemulsion; magnetisk respons; surfaktant; co-surfaktant; imidazoliumkatjon; polaritet; kedjelängdseffekt;

    Abstract : This research thesis reports experimental work done to design a stable magneticmicroemulsion of ionic liquid in 2-ethylhexyl laurate with the help of an ionic surfactant andan alcohol co-surfactant. The ionic liquids tested were based on a 1,3-dialkylimidazoliumcation with different alkyl chain lengths and a tetrachloroferrate anion ([FeCl4]+) to ensure theemulsion is sensitive to applied magnetic fields.

  5. 4. Conservative Discontinuous Cut Finite Element Methods: Convection-Diffusion Problems in Evolving Bulk-Interface Domains

    University essay from KTH/Matematik (Inst.)

    Author : Sebastian Myrbäck; [2022]
    Keywords : numerical analysis; mathematical modeling; convection-diffusion equation; partial differential equation; unfitted method; CutFEM; finite element method; discontinuous Galerkin method; numerisk analys; matematisk modellering; konvektions-diffusionsekvationer; partiella differentialekvationer; finita elementmetoden; diskontinuerliga Galerkinmetoden;

    Abstract : This work entails studying unfitted finite element discretizations for convection-diffusion equations in domains that evolve in time. In particular, these partial differential equations model the evolution of the concentration of soluble surfactants in bulk-interface domains. READ MORE

  6. 5. Considerations and Novel Technologies in Industrial Water Treatment - Treatment of challenging wastewater

    University essay from KTH/Kemiteknik

    Author : Nils Toll; [2021]
    Keywords : Industrial water treatment; considerations; novel technologies; BOD; COD; organic waste; heavy metals; desalination; Industriell vattenrening; nyckelfaktorer; nya teknologier; organiskt avfall; tungmetaller; avsaltning;

    Abstract : Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. READ MORE
