    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…

    Could COVID_19 mark a turning point for global action on climate change?
    16 Sep 2021
    University of Sydney
    Patel, Riya Rameshkumar Dickson, Rebecca Jane Lynette

    COVID-19 and climate change are both threats of immense proportions, however, the differing perception of climate change as far-off, projected and unpredictable, persists as a marked barrier to global action. COVID-19 is increasing awareness of the connection between human actions and environmental consequences. The current slowdown of fossil fuel use has given a glimpse of the quitter, cleaner a…

    The association of wildfire air pollution with COVID-19 incidence in New South Wales, Australia
    26 Nov 2021
    University of Sydney
    Cortes-Ramirez, J. Michael, R.N. Knibbs, L.D. Bambrick, H.J. Haswell, M.R. Wraith, D.

    The 2020 COVID-19 outbreak in New South Wales (NSW), Australia, followed an unprecedented wildfire season that exposed large populations to wildfire smoke. Wildfires release particulate matter (PM), toxic gases and organic and non-organic chemicals that may be associated with increased incidence of COVID-19. This study estimated the association of wildfire smoke exposure with the incidence of COV…

    Fluidization of lactose carrier powders through normally directed airflow: The effect of recirculation and particle size
    02 Dec 2021
    University of Sydney
    Elserfy, K Kourmatzis, A Singh, G Chan, HK Cheng, S

    This study investigates the fluidization of lactose carriers from a powder bed subjected to a normal force in a channel flow using high-speed imaging, particle image velocimetry (PIV), and high-speed, long-distance microscopy (HS-LDM). Pharmaceutical lactose carriers (LH200 and SV010) with different cohesiveness and fines percentages were examined in this study. Airflow velocities in the range of…

    Effect of Inflow Conditioning for Dry Powder Inhalers
    03 Dec 2021
    University of Sydney
    Singh, G Lowe, A Azeem, A Cheng, S Chan, HK Walenga, R Kourmatzis, A

    The transport of pharmaceutical dry powder inside an optically accessible inhaler-like device is studied using both macro- and microscopic high-speed imaging. The investigation aims to systematically study the effect of inflow modifications on the dispersion characteristics of agglomerates inside a dry powder inhaler (DPI) geometry. An inhaler device was designed with geometrical features akin to…

    Rapid review: Estimates of incremental breast cancer detection from tomosynthesis (3D-mammography) screening in women with dense breasts.
    09 Dec 2021
    University of Sydney
    Houssami, Nehmat Turner, Robin M

    High breast tissue density increases breast cancer (BC) risk, and the risk of an interval BC in mammography screening. Density-tailored screening has mostly used adjunct imaging to screen women with dense breasts, however, the emergence of tomosynthesis (3D-mammography) provides an opportunity to steer density-tailored screening in new directions potentially obviating the need for adjunct imaging…

    Experimental investigation into turbulent negatively buoyant jets using combined PIV and PLIF measurements
    20 Dec 2021
    University of Sydney
    Milton-McGurk, Liam Williamson, Nicholas Armfield, Steven Kirkpatrick, Michael

    Turbulent negatively buoyant jets occur when the buoyancy of a jet opposes its source momentum. In these flows, the fluid will rise until it reaches a stagnation point and a return flow is established, forming a fountain (Hunt and Burridge, 2015). This study looks at both the initial negatively buoyant jet stage of this flow, before the return flow has established, and the fully developed fountai…

    p39R861-4, a type 2 A/C2 plasmid carrying a segment from the A/C1 RA1
    11 Mar 2016
    University of Sydney
    Anantham, S Harmer, Christopher J Hall, Ruth M

    The largest plasmid in the strain 39R861, which is used as a plasmid size standard, was recovered by conjugation and sequenced to determine its exact size. Plasmid p39R861-4 transferred at high frequency. Though reported to be the A/C1 plasmid RA1, p39R861-4 is a 155794 bp Type 2 A/C2 plasmid in which a 39 kb segment derived from RA1 that includes a relative of the RA1 resistance island replaces …

    University of Sydney
    de la Monte, SM Kay, J Yalcin, EB Kril, JJ Sheedy, D Sutherland, GT

    BACKGROUND: Chronic alcohol use disorders (AUD) are associated with white matter (WM) degeneration with altered myelin integrity. Matrix assisted laser desorption ionization-imaging mass spectrometry (MALDI-IMS) enables high throughput analysis of myelin lipid biochemical histopathology to help characterize disease mechanisms. PURPOSE: This study utilized MALDI-IMS to investigate frontal lobe WM …
