  1. 1. Electromagnetic Heating of Coated Ellipsoidal Gold Nanoparticles in Biological Tissue at Radio Frequencies

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

    Author : Olle Hennert; Robert Themptander; [2023]
    Keywords : ;

    Abstract : Radiofrequency heating of gold nanoparticles for use in remote hyperthermia cancer treatment has seenrapidly growing interest in the last decade. While most of the focus has been on studying sphericalnanoparticles, a recent report suggests ellipsoidal particles can significantly increase heat absorption. READ MORE

  3. 2. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Claudia Bartos; [2022]
    Keywords : ATP bioluminescense; redox potential; bacillus; board production;

    Abstract : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants. In the manufacturing process, microbiological growth occursdue to environmental favourable conditions. READ MORE

  4. 3. Water quality and organic matter linkages in waters draining arable fields

    University essay from SLU/Dept. of Soil and Environment

    Author : Adam Eriksson; [2021]
    Keywords : Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

  5. 4. Internal charging modelling of the AMBER instrument on-board Jason-3 spacecraft

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

    Author : Jeremie Hacquart; [2020]
    Keywords : Internal Charging; Satellite; Plasma; SPIS; Intern laddning; satellit; plasma; SPIS;

    Abstract : Internal charging is the accumulation of charged particles inside a material. Thisbuild up represents a serious hazard to satellites and instruments exposed to thespace environment. The Van Allen radiation belts constitute one of the worst spaceenvironments for satellites orbiting the earth. READ MORE

  6. 5. Volatile fatty acid production and application as external carbon source for denitrification

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Cora Michelle Döhler; [2020]
    Keywords : VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Abstract : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.
