  1. 1. Synthesis and Characterization of Materials for Carbon Based Hybrid Asymmetric Supercapacitor Electrodes

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Avital Cherednik; [2023]
    Keywords : Supercapacitor; hybrid supercapacitor; metal oxide nanoparticles; carbon electrodes; ionic liquid; Superkondensator; hybrid superkondensator; metaloxid nanopartiklar; kolelektroder; jonvätska;

    Abstract : Superkondensatorer är energilagringsenheter som har uppmärksammats mer under det senaste decenniet. Några av de fördelar som dessa enheter har varit är lagring av hög effekttäthet, förlängda livscykler och snabba laddnings- och urladdningstider. READ MORE

  3. 2. Development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the contextof hydrogen mobility

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : WULLSCHLEGER LÉA; [2023]
    Keywords : Liquefaction cycle; multi-streams heat exchanger; Matlab; PROOSIS; AMESIM; ArianeGroup;

    Abstract : This paper presents the master thesis work done at ArianeGroup on the development and characterization of multi-streams heat exchangers for liquefaction cycle analysis in the context of hydrogen mobility. In 2015, the Paris Agreements aimed at strengthening the global response to the threat of climate change by keeping the temperature rise below 1. READ MORE

  4. 3. Characterization of Pressure and Velocity Fields in Acoustophoresis Using Particle Tracks

    University essay from KTH/Tillämpad fysik

    Author : Jonathan Karlsson; [2023]
    Keywords : Acoustofluidics; Acoustophoresis; Ultrasonic Standing Waves; Acoustic fields; Particle tracking; Bio marking; Akustofluidik; Akustofores; Stående Ultraljuds Vågor; Akustiska fält; Particle tracking; Bio-markering;

    Abstract : This master’s thesis explores the possibility of calculating and using the pressure andvelocity fields responsible for acoustophoresis. The goal was to use simulated data,similar to two-dimensional particle tracks from a specific microfluidic platform, toestimate the force potential and solve the partial differential equation (PDE) thatgoverns the relationship between the force potential and the acoustic fields.

  5. 4. Characterization of NOx sensor performance under oscillating pressure conditions

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Álvaro López Méndez; [2023]
    Keywords : NOx sensors; engine – out heavy duty vehicle conditions; oscillating pressure; test rig testing; NOx-sensorer; motor – ut tunga fordonsförhållanden; oscillerande tryck; testriggtestning;

    Abstract : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger. READ MORE

  6. 5. Enhancing Geophysical Applications with Electrical Resistivity Tomography Inversion : Uncovering the mysteries that lies beneath us

    University essay from Umeå universitet/Institutionen för fysik

    Author : Anton Morian; [2023]
    Keywords : Resistivity inversion; Filtering; 3D visualisation;

    Abstract : Geophysical methods have been widely used to investigate the subsurface in various ap-plications, such as mineral exploration, geotechnical and environmental studies. Among these methods, electrical resistivity tomography (ERT) has gained popularity due to its non-invasive and high-resolution capability in mapping subsurface resistivity variations. READ MORE
