  1. 21. Increasing the Writing Resolution for Electro-hydrodynamic 3D-Printing : by Active Steering of e-jet

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Henrik Dan Bergman; [2019]
    Keywords : EHD; Electro-hydrodynamic; 3D-printing; Resolution; PCL; e-jet; Additive Manufacturing;

    Abstract : Additive manufacturing has grown considerably during the last couple of decades, whether it comes to the printing of metal structure or living cells. Additive manufacturing techniques relays on the successive addition of material to create the wanted structure. READ MORE

  3. 22. Sodium trapping in aluminium current collectors

    University essay from Uppsala universitet/Strukturkemi

    Author : Ville Nyström; [2019]
    Keywords : Na; sodium; trapping; current collector; Al; aluminium; glyme; diglyme;

    Abstract : The aim of this master thesis was to establish if sodium is trapped in aluminium current collectors, which in turn could affect the capacity fade in sodium-ion battery systems. In the case of lithium-ion batteries, previous studies have shown that a trapping mechanism, where lithium diffuses through the active material and current collectors, can explain the capacity fade observed for several systems.

  4. 23. Preamplifier Design for Active Electrodes in Single-Channel EEG Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Thorir Marwan Abed; [2018]
    Keywords : Electroencephalography EEG ; single-channel; active electrode; current feedback instrumentation amplifier CFIA ; DC servo loop DSL ; portability.; Elektroencefalografi EEG ; singelkanal; aktiv elektrod; strömåterkoppling instrumentförstärkare; DC servo loop DSL ; bärbarhet.;

    Abstract : The implementation of portable electroencephalography (EEG) systems has been known to be complex. During ambulation, the integrity of recorded EEG signals is often impaired by motion artifacts and the time and effort required to set up the system is excessive. READ MORE

  5. 24. Fabrication and characterization of gate last Si MOSFETs with SiGe source and drain

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Björn Christensen; [2017]
    Keywords : MOSFET fabrication; gate last; SiGe source and drain; IDP gate; epitaxy; MOSFET fabrication; gate last; SiGe source and drain; IDP gate; epitaxy;

    Abstract : The continuous evolution of digital technology we enjoy today is the result of ever shrinking, faster and cheaper transistors that make up the ubiquitous integrated circuits of our devices. Over the decades, the industry has gone from purely geometrical scaling to innovative solutions like high-k dielectrics combined with metal gates and FinFETs. READ MORE

  6. 25. Investigation of novel, redox-active organic materials for lithium-ion and lithium-oxygen batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Antonia Kotronia; [2016]
    Keywords : lithium-ion; lithium-oxygen; organic electrode materials; organic catalysts;

    Abstract : This thesis encompasses the successful synthesis, characterization (NMR, IR, TGA) and electrochemical testing of novel, potentially redox-active organic materials. These were destined as electrodes for Li-organic cells and/or as catalysts for Li–O2 cells. READ MORE
