  1. 1. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Kasper Malmborn; [2023]
    Keywords : Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Abstract : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. READ MORE

  3. 2. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    University essay from KTH/Kemi

    Author : Arezu Sehati; [2023]
    Keywords : Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Abstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

  4. 3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Jonas Beling; [2023]
    Keywords : ion; physics; ion physic; scattering; desorption; sputtering; jon; fysik; jonfysik;

    Abstract : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. READ MORE

  5. 4. Investigation of Ion Extraction Anomalies at TwinEBIS

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Niek van Woudenberg; [2023]
    Keywords : CERN; ISOLDE; Ion Source; EBIS; REXEBIS; TwinEBIS; Ion losses; Charge Breeding; Ion Extraction; CST Studio Suite; Physics and Astronomy;

    Abstract : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. READ MORE
