    Sammanfattning : The present thesis is the result of a research period at the Institute of Space and Astronautical Science of the Japanese Aerospace Exploration Agency, ISAS/JAXA within Funaki Laboratory of the Department of Space Flight Systems that followed the path of plume plasma diagnostics for space electric propulsion drives. During the experimental studies two high-current hollow cathodes and an innovative prototype of a low-voltage fully external discharge plasma thruster (XPT) had their plasma plumes diagnosed using electrostatic probes and retarding potential analyser (RPA).

  2. 2. Fabrication and Validation of a Nano Engineered Glucose Powered Biofuel Cell

    Master-uppsats, KTH/Material- och nanofysik

    Författare :Srejith Satheesh; [2014]
    Nyckelord :fuel Cells; Nanotechnology; Nanomaterials; Nanocatalysis; Bifule cells; Glucose;

    Sammanfattning : Fuel Cells are important forms of sustainable power generation and Biofuel Cells utilize the use of bio-compatible/biodegradable molecules as fuels. Glucose is an ideal candidate to serve this purpose. In this project, a Glucose Fuel Cell (GFC) has been fabricated using the nanomaterials developed in the lab. LÄS MER
