  1. 1. Electrochemical Capacitors for Miniaturized Self-powered Systems

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Qi Li; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; AC line filters; Electrode materials; Electrochemical capacitors; Miniaturized self-powered systems; Electrolyte materials; Energy storage;

    Abstract : Miniaturized self-powered systems with harvest-store-use architectures have been recognized as a key enabler to the internet-of-things (IoT), and further the internet-of-everything (IoE), 5G communication and tactile internet. Electrochemical capacitors (ECs), also known as supercapacitors, are promoted to be the energy storage component in such systems, because of their advantages such as an almost limitless cycle life that is ideal for the vision of “fit-and-forget” maintenance-free networks.

  2. 2. Polyelectrolyte-Based Capacitors and Transistors

    University dissertation from Norrköping : Linköping University Electronic Press

    Author : Oscar Larsson; Linköpings universitet.; Linköpings universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; Polarization; Polyelectrolyte; Transistor; Polymer; Sensor; Capacitor; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Polymers are very attractive materials that can be tailored for specific needs and functionalities. Based on their chemical structure, they can for instance be made electrically insulating or semiconducting with specific mechanical properties. READ MORE

  3. 3. Polarization characteristics in polyelectrolyte thin film capacitors Targeting field-effect transistors and sensors

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Oscar Larsson; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Polymers are very attractive materials that can be tailored for specific needs and functionality. They can for instance be made electrically insulating or (semi)conducting, with specific mechanical properties. Polymers are often processable from a solution, which enables the use of low-cost manufacturing techniques to fabricate polymer devices. READ MORE

  4. 4. Electrochemical and ion transport characterisation of a nanoporous carbon derived from SiC

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Marcelo Zuleta; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Cottrell equation; radial diffusion; chronoamperometry; potential step measurements; microelectrode technique; nanoporous carbon; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : In this doctoral project, a relatively new form of carbon material, with unique narrow pore size distribution around 7 Å and with uniform structure, has been electrochemically characterised using the single particle microelectrode technique. The carbon has been used as electrode material for supercapacitors. READ MORE

  5. 5. Molecular Electronic Devices based on Ru(II) Thiophenyl Pyridine and Thienopyridine Architecture

    University dissertation from Västerås : Mälardalen University

    Author : Robert Steen; Mälardalens högskola.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Fused Ligands; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of ultra-pure silicon, and therefore the computing power, will double every 18 to 24 months. However, around 2020 hardware manufacturers will have reached the physical limits of silicon. READ MORE
