    CO2 electrolysis to multicarbon products in strong acid
    13 Sep 2021
    University of Sydney
    Li, Fengwang

    Carbon dioxide electroreduction (CO2R) is being actively studied as a promising route to convert carbon emissions to valuable chemicals and fuels. However, the fraction of input CO2 that is productively reduced has typically been very low, <2% for multicarbon products; the balance reacts with hydroxide to form carbonate in both alkaline and neutral reactors. Acidic electrolytes would overcome thi…

    Molecular stabilization of sub-nanometer Cu clusters for selective CO2 electro-methanation
    17 Nov 2021
    University of Sydney
    Li, Fengwang

    Electrochemical CO 2 methanation powered by renewable electricity provides a promising approach to utilizing CO 2 in the form of a high-energy-density, clean fuel. Cu nanoclusters have been predicted by theoretical calculations to improve methane selectivity. Direct electrochemical reduction of Cu-based metal-organic frameworks (MOFs) results in large-size Cu nanoparticles which favor multi-carbo…

    Service Recommendation in Smart Grid: Vision, Technologies, and Applications
    30 Jan 2020
    University of Sydney
    Luo, Fengji Ranzi, Gianluca Wang, Xibin Dong, Zhao Yang

    Driven by the energy crisis and global warming problem, smart grid was proposed in the early 21th century as a solution for the sustainable development of human society. With the two-way communication infrastructure available in smart grids, a current challenge is to interpret and gain knowledge from the collected grid big data to optimize grid operations. Service recommendation techniques provid…

    Healthy power: Reimagining hospitals as sustainable energy hubs
    17 Nov 2020
    University of Sydney
    Gurieff, N. Green, D. Koskinen, I. Lipson, M. Baldry, M. Maddocks, A. Menictas, C. Noack, J. Moghtaderi, B. Doroodchi, E.

    Human health is a key pillar of modern conceptions of sustainability. Humanity pays a considerable price for its dependence on fossil-fueled energy systems, which must be addressed for sustainable urban development. Public hospitals are focal points for communities and have an opportunity to lead the transition to renewable energy. We have reimagined the healthcare energy ecosystem with sustainab…

    Liu, Huimin Wu, Ping Li, Haitao Chen, Zibin Wang, Lizhuo Zeng, Xin Zhu, Yuxiang Jiang, Yijiao Liao, Xiaozhou Haynes, Brian S. Ye, Jinhua Stampfl, Catherine Huang, Jun

    Harnessing the vast supply of solar energy as the driving force to produce ammonia from abundant nitrogen gas and water is beneficial for both relieving energy demands and developing sustainable chemical industry. Bulk carbon nitride (B-g-C3N4), exfoliated carbon nitride (E-g-C3N4) and graphite (g-C) supported Ru-K catalysts, denoted as Ru-K/B-g-C3N4, Ru-K/E-g-C3N4 and Ru-K/g-C, respectively, wit…

    Potential of wind-powered renewable energy membrane systems for Ghana
    15 Nov 2010
    University of Edinburgh
    Park, G.L. Schäfer, Andrea Richard, B.S.

    Areas of the world that lack fresh water often have an ample supply of wind or solar energy, making renewable energy an attractive option as a power source for desalination systems. Particularly, wind energy is attractive because of its relatively low cost, high efficiency, and recent technological advancements in this area of research. To open system applicability to a broader range of geographi…

    LLM magnons
    13 Apr 2017
    University of Witwatersrand
    de Mello Koch, R. Mathwin, C. Van Zyl, H.J.R.

    We consider excitations of LLM geometries described by coloring the LLM plane with concentric black rings. Certain closed string excitations are localized at the edges of these rings. The string theory predictions for the energies of magnon excitations of these strings depends on the radii of the edges of the rings. In this article we construct the operators dual to these closed string excitation…

    DNA damage and repair detected by the comet assay in lymphocytes of African petrol attendants: a pilot study

    Keretetse, G.S. Laubscher, P.J. Du Plessis, J.L. Pretorius, P.J. Van der Westhuizen, F.H. Van Deventer, E. Van Dyk, E. Eloff, F.C. Van Aarde, M.N. Du Plessis, L.H.

    Petrol attendants are exposed to petrol volatile organic compounds (VOCs) which may have genotoxic and carcinogenic effects. The single-cell gel electrophoresis assay (comet assay) is a method highly sensitive to DNA damage induced by environmental and occupational exposure to carcinogenic and mutagenic agents. The aim of this study was to evaluate the level of exposure of petrol attendants to pe…

    Carbon particle type characterization of the carbon behaviour impacting on a commercial-scale Sasol-Lurgi FBDB gasifier
    04 Aug 2010
    North-West University
    Bunt, J.R. Waanders, F.B. Wagner, N.J.

    Char-form analysis, whilst not yet an ISO standard, is a relatively common characterization method applied to pulverized coal samples used by power utilities globally. Fixed-bed gasification coal feeds differ from pulverized fuel combustion feeds by nature of the initial particle size (+6 mm, −75 mm). Hence it is unlikely that combustion char morphological characterization schemes can be directly…
