  1. 1. Synthesis of Graphene - Carbon Nanotube Hybrid Structures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Aniruddha Paul; [2021]
    Nyckelord :Graphene; Carbon nanotubes; Graphene-CNT hybrid structures; Chemical Vapor Deposition CVD ; Grafen; Kolnanorör; Grafen-CNT-hybridstrukturer; Kemisk ångdeposition CVD ;

    Sammanfattning : Graphene and Carbon nanotubes (CNTs) have been researched for more than a decade due to their extraordinary properties and advantages towards applications like electronics, structural re-enforcements, thermal management and energy storage. Graphene-CNT hybrid structures have been predicted to further enhance the exceptional properties and overcome some of the shortcomings of the individual materials. LÄS MER

  3. 2. Gadoliniumansamling hos patienter med multipel skleros samt implementering av artificiell intelligens vid magnetresonanstomografi

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik; Luleå tekniska universitet/Institutionen för hälsa, lärande och teknik

    Författare :Sofia Lindström; Maja Becarevic; [2021]
    Nyckelord :Gadolinium; deposition; signal intensity; magnetic resonance imaging; Xray nurse; radiographer; artificial intelligence; deep learning; multiple sclerosis; Gadolinium; ansamling; signalintensitet; magnetresonanstomografi; röntgensjuksköterska; radiografi; artificiell intelligens; deep learning; multipel skleros;

    Sammanfattning : Introduktion: Uppskattningsvis 40% av alla magnetresonanstomografiska (MRT) undersökningar som görs i Europa och USA utförs med gadoliniumbaserade kontrastmedel. Under det senaste decenniet har det i flera studier uppmärksammats att ansamling av gadolinium sker i olika strukturer i hjärnan. LÄS MER

  4. 3. Increasing forest mortality and its drivers: Simulating central European forests under climate change

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Marieke Scheel; [2021]
    Nyckelord :forest mortality; central Europe; competition; CO2; temperature; precipitation; DVM; LPJ-GUESS; simulation; reproducing data; Earth and Environmental Sciences;

    Sammanfattning : Increasing tree growth and mortality rates in Europe are still poorly understood and have been attributed to a variety of drivers. This study aimed to relate increasing forest mortality rates in six central European countries to climate drivers (CO2 concentration, temperature and precipitation) from 1985-2015, using a process-based vegetation model.

  5. 4. Intermediate layer contacts for tandem solar cells based on ALD SnO2

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Georgia Iona; [2021]
    Nyckelord :Ald; SnO2; tandem cell; solar cell; IML; intermediate layer;

    Sammanfattning : In this project, samples with a metal/semiconductor/metal structure were fabricated and investigated with the potential application as the interconnecting layer of a tandem solar cell in mind. Degenerately doped p-Si and n-Si were used as bottom (metal like) contacts, as Si represents one of the most common materials for the bottom cell of tandem devices. LÄS MER

  7. 5. A Lead (Pb) Mass-Balance Budget for a Dry Periglacial Catchment in West Greenland : Discussing the fate of pollutant Pb

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

    Författare :Andreas Nylund; [2020]
    Nyckelord :Lead mass-balance budget; Dry periglacial landscape; Whole catchment; Pollution; Climate change;

    Sammanfattning : Lead (Pb), occurs both naturally and as a pollutant in Arctic landscape systems. The ongoing climate change, especially pronounced in the Arctic, changes the premises for Pb transport and mobility. LÄS MER
