    • Spectral variability of radio sources at low frequencies
      Ross, Kat ; Callingham, J.R.; Hurley-Walker, Natasha ; Seymour, Nick ; Hancock, Paul ; Franzen, Thomas ; Morgan, John ; White, S.V.; Bell, M.E.; Patil, P. (2021)
      Spectral variability of radio sources encodes information about the conditions of intervening media, source structure, and emission processes. With new low-frequency radio interferometers observing over wide fractional ...
    • Remnant radio galaxies discovered in a multi-frequency survey
      Quici, B.; Hurley-Walker, Natasha ; Seymour, Nick ; Turner, Ross ; Shabala, S.S.; Huynh, M.; Andernach, H.; Kapińska, A.D.; Collier, J.D.; Johnston-Hollitt, Melanie ; White, S.V.; Prandoni, I.; Galvin, Tim ; Franzen, Thomas ; Ishwara-Chandra, C.H.; Bellstedt, S.; Tingay, Steven ; Gaensler, B.M.; O'Brien, A.; Rogers, J.; Chow, K.; Driver, S.; Robotham, A. (2021)
      The remnant phase of a radio galaxy begins when the jets launched from an active galactic nucleus are switched off. To study the fraction of radio galaxies in a remnant phase, we take advantage of a deg subregion of the ...
    • Nitric Oxide and Other Molecules: Molecular Modeling and Low-frequency Exploration Using the Murchison Widefield Array
      Tremblay, C.D.; Gray, M.D.; Hurley-Walker, Natasha ; Green, J.A.; Dawson, J.R.; Dickey, J.M.; Jones, P.A.; Tingay, Steven ; Wong, O.I. (2020)
      We present new molecular modeling for 14NO and 15NO and a deep, blind molecular line survey at low radio frequencies (99-129 MHz). This survey is the third in a series completed with the Murchison Widefield Array (MWA), ...
    • Growing the Volunteer Pool: Identifying Non-Volunteers Most Likely to Volunteer
      Lockstone-Binney, L.; Holmes, Kirsten ; Meijs, L.C.P.M.; Oppenheimer, M.; Haski-Leventhal, D.; Taplin, Ross (2022)
      There are ongoing management and societal challenges affecting volunteering participation. These place a premium on organizations identifying individuals that currently do not volunteer but have the willingness and capacity ...
    • Insights into the mechanism of tar reforming using biochar as a catalyst
      Liu, Y.; Paskevicius, Mark ; Wang, H.; Parkinson, G.; Wei, J.; Asif Akhtar, M.; Li, Chun-Zhu (2021)
      Biochar is an efficient catalyst for tar removal from syngas during biomass gasification. The aim of this research is to investigate the mechanism of tar reforming using biochar as a catalyst. A series of in situ steam ...
    • A SAXS study of the pore structure evolution in biochar during gasification in H2O, CO2 and H2O/CO2
      Liu, Y.; Paskevicius, Mark ; Sofianos, M.V.; Parkinson, G.; Wang, Shuai ; Li, Chun-Zhu (2021)
      Gasification of biomass allows for its efficient utilisation as a renewable fuel through syngas production. This work presents the different effects of gasifying agents (H2O, CO2 and H2O/CO2) on the pore structure evolution ...
    • In situ SAXS studies of the pore development in biochar during gasification
      Liu, Y.; Paskevicius, Mark ; Sofianos, M.V.; Parkinson, G.; Li, Chun-Zhu (2021)
      This work investigates the pore development in biochar during gasification using synchrotron small angle X-ray scattering (SAXS) as an in situ characterization technique. The influence of the gasifying agents (H2O, CO2 ...
    • Thermochemical energy storage properties of a barium based reactive carbonate composite
      Møller, K.T.; Williamson, Kyran ; Buckley, Craig ; Paskevicius, Mark (2020)
      This study introduces a new concept of reactive carbonate composites (RCCs) for thermochemical energy storage, where a BaCO3-BaSiO3mixture offers a successful thermodynamic destabilisation of BaCO3with moderate cyclic ...
    • Inexpensive thermochemical energy storage utilising additive enhanced limestone
      Møller, K.T.; Ibrahim, A.; Buckley, Craig ; Paskevicius, Mark (2020)
      Energy storage is one of the key challenges in our society to enable a transition to renewable energy sources. The endothermic decomposition of limestone into lime and CO2is one of the most cost-effective energy storage ...
    • Decomposition pathway of KAlH4 altered by the addition of Al2S3
      Sheppard, Drew ; Jepsen, L.H.; Rowles, Matthew ; Paskevicius, Mark ; Jensen, T.R.; Buckley, Craig (2019)
      Altering the decomposition pathway of potassium alanate, KAlH 4 , with aluminium sulfide, Al 2 S 3 , presents a new opportunity to release all of the hydrogen, increase the volumetric hydrogen capacity and avoid complications ...
