  1. 1. Investigation of different ventilation profiles to avoid stratification in Nearly Zero Energy Buildings

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Alazne Irene Varela Santana; [2023]
    Nyckelord :stratification; water model; comfort; mixing; temperature; potential energy; net zero energy building;

    Sammanfattning : This research paper examines possible solutions for the problems that warm air heating is suffering in Nearly Zero Energy Buildings. These NZEBs are passive houses constructed to have high energy efficiency where the quantity of power used is equal to the power created annually, produced locally or in the surroundings by renewable energy sources.

  3. 2. Design and investigation of a pulsating heat pipe for electronic cooling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sulafa Hammad; [2023]
    Nyckelord :Pulsating heat pipes PHP ; Electronic cooling; two phase flow heat transfer; Technology and Engineering;

    Sammanfattning : The purpose of this study is to design and investigate a pulsating heat pipe device (PHP). A PHP is a two-phase flow heat transfer device which can handle high heat fluxes with passive internal flow. It is made of a continuous loop serpentine, partially filled with a working fluid that can cool systems, such as electronic devices. LÄS MER

  4. 3. Production, in vitro modification, and interaction analysis of a hydroxyproline-dependent protein

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Biokemi

    Författare :Milica Plavsic; [2023]
    Nyckelord :protein production optimisation; recombinant expression; bioreactor; prolyl hydroxylase; liquid chromatography mass spectrometry; microscale thermophoresis;

    Sammanfattning : The development of a biologic protein involves different stages and becomes a highly complex process which can be costly and time consuming to scale up for industrial production. Therefore, optimization is a necessary part of the production process development to lower the production expenses. LÄS MER

  5. 4. Experimental Testing of Solar Photovoltaic/Thermal Collectors for Low Temperature Heat Pump Integration

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jaakko Eskola; [2023]
    Nyckelord :Solar photovoltaic thermal; PVT; heat pump; thermal performance; ISO 9806:2017; Solhybrid; PVT; värmepump; termisk prestanda; ISO 9806:2017;

    Sammanfattning : A hybrid photovoltaic/thermal (PVT) collector enables simultaneous electricity and heat production from a single solar module. Integrating PVT collectors with a ground source heat pump (GSHP) improves the seasonal performance of the heating system and prevents from temperature degradation of the ground. LÄS MER

  7. 5. Light-activated gas sensing with copper oxide micro- and nanostructures

    Kandidat-uppsats, KTH/Fysik

    Författare :Gabriel Yousef; Carl Persson; [2022]
    Nyckelord :Gas sensors; Gas sensing; Light-activation; Copper oxide; Cuprous Oxide; Nanomaterials;

    Sammanfattning : Metal oxide semiconductor (MOS) gas sensors have proven to be useful in many applications, ranging from detection of hazardous gases to monitoring of air quality. The demand for power efficient and high performance gas sensors has seen an increase in situations facing contemporary society. LÄS MER
