  1. 1. Glucose Sensing and Differentiating Systems with Organic Electrochemical Neurons : A Future Outlook for Type 2 Diabetes

    Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap

    Författare :Sophie Ziske; [2024]
    Nyckelord :organic electronics; organic electrochemical neuron; organic electrochemical transistor; type 2 diabetes; closed-loop system; Axon-Hillock neuron; astable multivibrator; vagus nerve stimulation; glucose sensing and differentiation; applied physics; biomedical engineering; electronics;

    Sammanfattning : In recent years great advances in the field of biomedical engineering and organic electronics have been achieved. One promising application would be the regulation of blood glucose concentration in type 2 diabetes patients. This application would eliminate medication and would improve the standard of life.

  3. 2. Barium in the O horizon of soils near Sundsvall, northern Sweden : From local minerals or from anthropogenic emissions?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mattias Åsberg Gencturk; [2023]
    Nyckelord :Barium; soil; organic horizon;

    Sammanfattning : Concentrations of potentially toxic metals in surface soils are important to investigate before building new residential areas. Prior to development of a residential area in Sundsvall, northern Sweden, it was observed that barium (Ba) concentrations in the soil at the site exceeded the guideline value of 200 mg kg-1 outlined by the Swedish Environmental Protection Agency.

  4. 3. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mattias Sundin; [2023]
    Nyckelord :Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

    Sammanfattning : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. LÄS MER

  5. 4. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Rickard Gauffin; [2022]
    Nyckelord :XPS; HAXPES; IMFP; Polymer;

    Sammanfattning : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. LÄS MER

  7. 5. Investigations of the Thermal Runaway Process of a Fluorine-Free Electrolyte Li-Ion Battery Cell

    Master-uppsats, KTH/Kemiteknik

    Författare :Tamara Patranika; [2021]
    Nyckelord :Lithium-ion batteries; Electrolyte; Non-fluorinated; Thermal stability; Litiumjonbatteri; Elektrolyt; Fluorfri; Termisk stabilitet;

    Sammanfattning : Detta projekt syftar till att undersöka den termiska rusningsprocessen hos ett litiumjonbatteri med en fluorfri elektrolyt och jämföra den med en kommersiellt använd fluor-innehållande elektrolyt. Battericellerna innehöll silikon-grafit som anod och LiNi0.6Mn0.2Co0. LÄS MER
