  1. 6. Improving cell secretome analysis and bacteria evolution by means of acoustophoresis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Moritz Leuthner; [2020]
    Keywords : acoustophoresis; acoustofluidic; lab-on-a-chip; acoustic streaming; acoustic radiation force; particle trapping; particle washing; bulk acoustic waves; BAW; media exchange; cell manipulation;

    Abstract : In both, cell secretome analysis and bacteria evolution, controlled handling of particles with a few to sub-micrometers in size and media exchange are inevitable in order to investigate body fluid’s proteins or change the surrounding culture conditions for pivoted evolution. Typically, nanofiltration and ultra-centrifugation are employed which can lead to cell damage, need large sample volumes and have a high sample loss. READ MORE

  3. 7. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Pascal Camoiras González; [2019]
    Keywords : ;

    Abstract : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

  4. 8. Indoor Air Pollution, Passive Ventilation Strategies and Thermal Comfort in Nepal

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Marianne Löwgren; [2019]
    Keywords : Energy poverty; Solid biomass fuels; Improved cooking stoves; Indoor air pollution; Carbon monoxide; Vernacular architecture; Passive ventilation; Air exchange rate; Indoor air quality; Thermal comfort; Operative temperature; Sustainable societal development; Social Sciences; Technology and Engineering;

    Abstract : Indoor Air Pollution (IAP) resulting from indoor burning of solid biomass fuels in poorly ventilated kitchens is a severe health risk in parts of the world where energy poverty is prevalent. Passive ventilation, i.e. taking advantage of naturally induced airflow has been suggested as crucial in reducing IAP levels below safe limits. READ MORE

  5. 9. Thermoeconomic analysis of LNG physical exergy use for electricity production in small-scale satellite regasification stations

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Dominykas Balciunas; [2019]
    Keywords : LNG; exergy; thermodynamics; economics; thermoeconomic analysis; small scale; satellite; regasification;

    Abstract : Liquefied natural gas (LNG) cold utilization in small scale regasification stations is a novel topic in the industry, while such systems have been proven feasible in large scale LNG facilities. Cold recovery and utilization in LNG regasification facilities would increase the thermodynamic efficiency and reduce cold pollution. READ MORE

  6. 10. AA-CAES physical modelling: integration of a 1D TES code and plant performance analysis

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Luca Santo; [2018]
    Keywords : energy storage; balancing; grid; AA-CAES; CAES; peaks; energy scenarios; s-function; simulink; simscape; matlab; C ; TES; thermal energy storage; dumping; demand side management; power systems; turbine; compressor; cavern; CAS; compressed air; heat exchange;

    Abstract : The focus of this thesis work was the development of an approachto couple a previosly existing Thermal Energy Storage (TES) modelwritten in C++ with a Simulink/Simscape plant model to simulate anAdvanced Adiabatic Compressed Air Energy Storage (AA-CAES) plant.After the creation and validation of such tool, the complete modelwas used to run simulations, with the aim of assessing the AA-CAESplant's performance under multiple patterns of charge anddischarge.
