Electrodeposition Of Pyrrole And 3-(4-Tert-Butylphenyl)Thiophene Copolymer For Supercapacitor Applications, Binbin Yue, Caiyun Wang, Pawel Wagner, Yang Yang, Xin Ding, David L. Officer, Gordon G. Wallace

Faculty of Science, Medicine and Health - Papers: part A

The electropolymerization of pyrrole (Py), 3-(4-tert-butylphenyl)thiophene (TPT) monomer or the mixed Py and TPT monomers on stainless steel mesh substrate were performed in 1 M LiClO4/acetonitrile solution. A much lower potential of 0.75 V was required for the co-electropolymerization of Py and TPT, in sharp contrast to that of 1.20 V for poly(3-(4-tert-butylphenyl)thiophene) (PTPT) formation. The resultant homopolymers and copolymer were characterized with FESEM and FTIR, and assembled into supercapacitors to investigate their electrochemical performances. The copolymer electrode delivered the highest specific capacitance of 291 F g−1 at a scan rate of 5 mV s−1, in comparison with that of …

A Hunt For Elusive Trace Gases In The Marine Boundary Layer, M Henchion, N B. Jones, D W. T Griffith, C Paton-Walsh Jan 2012

A Hunt For Elusive Trace Gases In The Marine Boundary Layer, M Henchion, N B. Jones, D W. T Griffith, C Paton-Walsh

Faculty of Science, Medicine and Health - Papers: part A

We present a feasibility study into the use of solar remote sensing Fourier transform infrared spectrometry (FTS) to detect elusive trace gases in the marine boundary layer. The study acquired spectra from Wollongong, Australia (34.5°S, 150°E, 30m above sea level) at dawn as the sun rose over the ocean. We hoped to detect elusive atmospheric trace gases such as hypochlorous acid (HOCl) and dinitrogen pentoxide (N2O5) in these spectra, since the geometry results in path-lengths through the marine boundary layer in excess of 100km at dawn. Spectra were successfully collected at SZA greater than 90° above the marine horizon on …

Fires regularly affect many of the world's terrestrial ecosystems, and, as a result, fires mediate the exchange of greenhouse gases (GHG) between the land and the atmosphere at a global scale and affect the capacity of terrestrial ecosystems to store carbon (Bowman et al. 2009). Variations in fire -regimes can therefore potentially affect the global, regional and local carbon balance and, potentially, climate change itself (Bonan 2008). Here we examine how variation in fire regimes (Gill 1975; Bradstock et al. 2002) will potentially affect carbon in fire-prone Australian ecosystems via interactions with the stocks and transfers of carbon that are …

Global Change And Fire Regimes In Australia, Geoffrey J. Cary, Ross A. Bradstock, A Malcolm Gill, Richard J. Williams Jan 2012

Global Change And Fire Regimes In Australia, Geoffrey J. Cary, Ross A. Bradstock, A Malcolm Gill, Richard J. Williams

Faculty of Science, Medicine and Health - Papers: part A

Global change can be defined strictly in terms of changes in atmospheric composition, climate and land use (Walker and Steffen 1996), although broader definitions also include human population, economy and urbanisation (Steffen et al. 2004). In Australia, global change significantly affects the drivers of fire activity and there is potential for considerable changes in fire regimes. It is widely accepted that carbon dioxide (C02) concentration in the atmosphere is steadily increasing (see Steele et al. 2007), as is nitrous oxide (Forster et al. 2007). Atmospheric methane concentration has also risen significantly, but is now relatively constant (Beer et al. 2006). …

Faculty of Science, Medicine and Health - Papers: part A

The practical usefulness of a desktop optical spectrum analyzer (OSA) for measuring atmospheric CO2 and CH4 column densities at surface sites was examined in two separate measurement campaigns. The first comparison involved operating the OSA in parallel with a high resolution Fourier transform spectroscopy (FTS) situated at the University of Wollongong in Australia. Scale factors for the OSA were assigned for the column average volume mixing ratios of xCO2 and xCH4 by comparing with the well-studied FTS. The second method is a calibration against aircraft CO2 profiles in situ over Tsukuba in Japan obtained during a GOSAT validation campaign carried …

Incorporating Estuaries As A Source Or Sink Of Sediment Within Assessments Of Coastline Risk And Adaptation To Climate Change, K Rogers, C D. Woodroffe Jan 2012

Incorporating Estuaries As A Source Or Sink Of Sediment Within Assessments Of Coastline Risk And Adaptation To Climate Change, K Rogers, C D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Complex coastal landforms exhibit variable behaviour in response to sea-level rise. A proposed modelling framework that integrates shoreline changes associated with longterm recession, short-term variability and sea-level rise advocates that coastal risk assessment be undertaken within the context of a geomorphologically-based modelling framework whereby a coastline is subdivided into coastal compartments or cells, thereby recognising the sedimentary links between compartments. For example, the Narrabeen coastline includes bounding headland compartments, a bay compartment and an estuary compartment; and the behaviour of the coastline varies according to the response of each of these compartments to variable climatic and oceanic conditions. This approach …

Archaeological Science In Australia: Integrating Across Disciplines And Scales Of Analysis, Zenobia Jacobs

Faculty of Science, Medicine and Health - Papers: part A

The basic questions in prehistoric archaeology have not changed much over the last forty years. In Australia, we continue to debate when and where Australia and its arid interior were first colonised, and whether or not these early colonisers were responsible for the extinction of the Australian megafauna. These questions are broad and any answers involve interdisciplinary teamwork that crosses conventional academic boundaries - the humanities and sciences.

Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart Jan 2012

Experimental And Computational Simulation Of Beta-Dose Heterogeneity In Sediment, Alastair C. Cunningham, Daniel J. De Vries, Dennis R. Schaart

Faculty of Science, Medicine and Health - Papers: part A

Interpreting the spread in equivalent-dose estimates is an important aspect of optically stimulated luminescence (OSL) dating. Ideally, prior to age estimation, an assessment should be made of the likely spread in equivalent dose due to dose-rate heterogeneity in the sediment. Such a procedure would greatly increase the validity of OSL ages, particularly for sediments susceptible to partial bleaching, and for sediments with coarse or poorly sorted grain-size distributions. In this paper we take a step towards a general model of dose-rate heterogeneity by simulating the 40K-derived beta dose to quartz. We present an experimental simulation of the 40K beta dose, …

[1] Recent studies have shown that measured OH under NOx-limited, high-isoprene conditions are many times higher than modeled OH. In this study, a detailed analysis of the HOx radical budgets under low-NOx, rural conditions was performed employing a box model based on the Master Chemical Mechanism (MCMv3.2). The model results were compared with HOx radical measurements performed during the international HOxComp campaign carried out in Jülich, Germany, during summer 2005. Two different air masses influenced the measurement site denoted as high-NOx (NO, 1-3 ppbv) and low-NOx (NO, < 1 ppbv) periods. Both modeled OH and HO2 diurnal profiles lay within the measurement range of all HOx measurement techniques, with correlation slopes between measured and modeled OH and HO2 around unity. Recently discovered interference in HO2 measurements caused by RO2 cross sensitivity was found to cause a 30% increase in measured HO2 during daytime on average. After correction of the measured HO2 data, the model HO2 is still in good agreement with the observations at high NOx but overpredicts HO2 by a factor of 1.3 to 1.8 at low NOx. In addition, for two different set of measurements, a missing OH source of 3.6 ± 1.6 and 4.9 ± 2.2 ppb h−1 was estimated from the experimental OH budget during the low-NOx period using the corrected HO2 data. The measured diurnal profile of the HO2/OH ratio, calculated using the corrected HO2, is well reproduced by the MCM at high NOx but is significantly overestimated at low NOx. Thus, the cycling between OH and HO2 is better described by the model at high NOx than at low NOx. Therefore, similar comprehensive field measurements accompanied by model studies are urgently needed to investigate HOx recycling under low-NOx conditions.

All Washed Up: Have Surf Megabrands Forgotten Their Roots?, Andrew T. Warren, Christopher Gibson

Faculty of Science, Medicine and Health - Papers: part A

Yesterday's announcement that iconic brand Rip Curl plans to sell-up raises the question: just what has happened to Australia's iconic surf brands? It has been well publicised that the big three surf labels - Rip Curl, Quiksilver and Billabong - have experienced shrinking sales and expanding debts. Suburban consumers have turned away from expensive surf-branded apparel. Coupled with the rise of online shopping, doubts are growing about the future viability of corporatised surf brands.

Synthesis Of Spirocyclic Azacycles From The Cyclization Of Furan Tethered N-Acyliminium Ions, Sudhir R. Shengule, Anthony Willis, Stephen G. Pyne

Faculty of Science, Medicine and Health - Papers: part A

The protic and Lewis acid promoted cyclization reactions of tethered furan-4,5-dihydroxypiperid-2-ones, furan-4,5-diacetoxypiperid-2-ones and furan-3,4-diacetoxypyrrolid-2-ones, via their corresponding N-acyliminium ion intermediates, have been studied. In the case of the furan-4,5-dihydroxypiperid-2-one 2a and its diacetate derivative 2b, macrocyclic products were formed from an initial intermolecular reaction between 2a or 2b, via the nucleophilic C5 furan carbon, and their corresponding N-acyliminium ion intermediates. When the furan C5 position of 2b was blocked by substitution with bromine then TFA or Sc(OTf)3 catalysed cyclization reactions gave a spirotricyclic product (a 5-6-6-tricycle) in a highly diastereoselective manner. Cyclization of the analogous C5-Br-furan-pyrrolidone 29 with TFA resulted …

The Drivers Of Effectiveness Of Prescribed Fire Treatment, Owen Francis Price Jan 2012

The Drivers Of Effectiveness Of Prescribed Fire Treatment, Owen Francis Price

Faculty of Science, Medicine and Health - Papers: part A

Prescribed burning for fuel reduction is a major strategy for reducing the risk from unplanned fire. Although there are theoretical studies suggesting that prescribed fire has a strong negative influence on the subsequent area of unplanned fire (so-called leverage), many empirical studies find a more modest influence. Here, I develop a series of simulations to explore the landscape drivers of leverage. Leverage declines with treatment level in a nonlinear, "decay" relationship, implying diminishing effectiveness. The spatial configuration of the prescribed fire treatment has a major effect: long linear (gridded) barriers are far more effective than patch barriers, but gaps in …

Streptokinase Variants From Streptococcus Pyogenes Isolates Display Altered Plasminogen Activation Characteristics - Implications For Pathogenesis, Simon M. Cook, Amanda Skora, Christine M. Gillen, Mark J. Walker, Jason D. Mcarthur Jan 2012

Streptokinase Variants From Streptococcus Pyogenes Isolates Display Altered Plasminogen Activation Characteristics - Implications For Pathogenesis, Simon M. Cook, Amanda Skora, Christine M. Gillen, Mark J. Walker, Jason D. Mcarthur

Faculty of Science, Medicine and Health - Papers: part A

Streptococcus pyogenes (group A streptococcus, GAS) secretes streptokinase, a potent plasminogen activating protein. Among GAS isolates, streptokinase gene sequences (ska) are polymorphic and can be grouped into two distinct sequence clusters (termed cluster type-1 and cluster type-2) with cluster type-2 being further divided into sub-clusters type-2a and type-2b. In this study, far-UV circular dichroism spectroscopy indicated that purified streptokinase variants of each type displayed similar secondary structure. Type-2b streptokinase variants could not generate an active site in Glu-plasminogen through non-proteolytic mechanisms while all other variants had this capability. Furthermore, when compared with other streptokinase variants, type-2b variants displayed a 29- …

Determining The Cooling Age Using Luminescence-Thermochronology, Bo Li, Sheng-Hua Li Jan 2012

Determining The Cooling Age Using Luminescence-Thermochronology, Bo Li, Sheng-Hua Li

Faculty of Science, Medicine and Health - Papers: part A

Luminescence technique has been shown to have great potential in low-temperature (< 100 °C) themochronology. This study investigates the kinetic process of luminescence in a cooling system. We present a new formula that can be used for determining the cooling age based on luminescence-thermochronology. The cooling rate can be obtained directly from a plot of luminescence age versus the present temperature. We show that the application and capacity of luminescence-thermochronology are significantly controlled by the saturation of luminescence and environmental dose rate.

Incorporating simulation in curricula is a strategy that provides innovative opportunities to address the challenges of preparing learners for the complexities of clinical practice (Jefferies, 2007). However, where students have had limited exposure to clinical practice their understanding of the context of this may impact on the quality of the learning experience. This is especially so when students are expected to engage in simulation activities that include role play. Using learning objects as a teaching tool and embedding these within the structure of simulation can enhance the quality of the learning experience through facilitating an understanding of the practice context, …
