  • Materials and fabrication of electrode scaffolds for deposition of MnO2 and their true performance in supercapacitors 

    Li, Xiaohong; Cao, J; Wang, Yaming; Walsh, Frank C.; Ouyang, J; Jia, D; Zhou, Y (Elsevier B.V., 2015-06-06)
    MnO2 is a promising electrode material for high energy supercapacitors because of its large pseudo-capacitance. However, MnO2 suffers from low electronic conductivity and poor cation diffusivity, which results in poor ...
  • The fabrication of a bifunctional oxygen GDE without carbon components for alkaline secondary batteries 

    Price, SWT; Thompson, SJ; Li, Xiaohong; Gorman, SF; Pletcher, Derek; Russell, AE; Walsh, Frank C.; Wills, RGA (Elsevier, 2014-02-26)
    The fabrication of a gas diffusion electrode (GDE) without carbon components is described. It is therefore suitable for use as a bifunctional oxygen electrode in alkaline secondary batteries. The electrode is fabricated ...

  • Acoustic Emission Health Monitoring of Marine Renewables - Illustration with a Wave Energy Converter in Falmouth Bay (UK) 

    Walsh, Jodi; Bashir, Imran; Thies, Philipp R.; Blondel, Philippe; Johanning, Lars (IEEE, 2015-06-25)
    Marine renewable energy (MRE) is an emerging technology and at present there are an increasing number of MRE prototypes and full-scale devices deployed. The future commercialization in the near future may contribute to the ...
  • A novel bifunctional oxygen GDE for alkaline secondary batteries 

    Li, Xiaohong; Pletcher, Derek; Russell, Andrea E.; Walsh, Frank C.; Wills, Richard G.A.; Gorman, Scott F.; Price, Stephen W.T.; Thompson, Stephen J. (Elsevier for International Society of Electrochemistry (ISE), 2013)
    This paper describes a novel procedure for the fabrication of a gas diffusion electrode (GDE) suitable for use as a bifunctional oxygen electrode in alkaline secondary batteries. The electrode is fabricated by pre-forming ...
  • High surface area coatings for hydrogen evolution cathodes prepared by magnetron sputtering

    A novel magnetron sputtering technique is described for the deposition of durable, high surface area metal and alloy deposits (thickness up to several microns) onto nickel and steel substrates. The materials deposited ...
  • Assessment of entanglement risk to marine megafauna due to offshore renewable energy mooring systems 

    Harnois, Violette; Smith, Helen C.M.; Benjamins, Steven; Johanning, Lars (Elsevier, 2015-09)
    This paper defines a methodology to compare different offshore renewable energy (ORE) mooring configurations in terms of the risk of entanglement they present to marine megafauna. Currently, the entanglement of large marine ...
  • A comparison of cathodes for zero gap alkaline water electrolysers 

    Pletcher, Derek; Li, Xiaohong; Wang, S (Elsevier, 2012)
    Selected coatings on nickel or stainless steel micromeshes have been examined as electrocatalysts for hydrogen evolution in conditions mimicking those found in zero gap alkaline water electrolysers. Voltammetry in 4 M NaOH ...
  • Numerical model validation for mooring systems: Method and application for wave energy converters 

    Harnois, Violette; Weller, S.D.; Johanning, Lars; Thies, Philipp R.; Le Boulluec, M.; Le Roux, Dominique; Soulé, V.; Ohana, J. (Elsevier, 2015)
    The design of wave energy mooring systems is challenging: overdesign incurs a significant cost penalty, underdesign may lead to a premature failure and incorrect design could reduce the power production. Consequently, ...
  • Control of Transient Power during Unintentional Islanding of Microgrids 

    Issa, Walid; Abusara, Mohammad; Sharkh, Suleiman (IEEE, 2014)
    In inverter-based microgrids, the paralleled inverters need to work in grid-connected mode and stand-alone mode and to transfer seamlessly between the two modes. In grid-connected mode, the inverters control the amount of ...
  • Physical measurement of a slow drag of a drag embedment anchor during sea trials 

    Harnois, Violette; Parish, D; Johanning, Lars (ICOE, 2012-10-17)
