Rational Catalyst Design For N2 Reduction Under Ambient Conditions: Strategies Towards Enhanced Conversion Efficiency, Lei Shi, Yu Yin, Shaobin Wang, Hongqi Sun

Research outputs 2014 to 2021

Ammonia (NH₃), one of the basic chemicals in most fertilizers and a promising carbon-free energy storage carrier, is typically synthesized via the Haber–Bosch process with high energy consumption and massive emission of greenhouse gases. The photo/electrocatalytic nitrogen reduction reaction (NRR) under ambient conditions has attracted increasing interests recently, providing alternative routes to realize green NH₃ synthesis. Despite rapid advances achieved in this most attractive research field, the unsatisfactory conversion efficiency including a low NH₃ yield rate, and limited Faradaic efficiency or apparent quantum efficiency still remains as a great challenge. The NRR performance is intrinsically related …

“The Pay Is Not Worth It But It Is Excellent Pd”: Australian Teachers’ Perspectives On Doing Large-Scale Marking, Nathanael Reinertsen

Research outputs 2014 to 2021

Anecdotally, teachers take up opportunities to mark large-scale assessments because they are told by colleagues that it is 'good PD'. Assertions about the value of marking are passed along with little question. However, research into the benefits of participating as a marker in large-scale marking has not been conducted in the Australian context. This paper reports the results of an online survey of Australian teachers (N=43) about their participation in large-scale marking in order to examine whether the research that has been conducted internationally is likely to be generalisable to Australia.

Amylin And Beta Amyloid Proteins Interact To Form Amorphous Heterocomplexes With Enhanced Toxicity In Neuronal Cells, Prashant Bharadwaj, Tanya Solomon, Bikash Sahoo, Katarzyna Ignasiak, Scott Gaskin, Joanne Rowles, Guiseppe Verdile, Mark Howard, Charles S. Bond, Ayyalusamy Ramamoorthy, Ralph Martins, Philip Newsholme

Research outputs 2014 to 2021

Human pancreatic islet amyloid polypeptide (hIAPP) and beta amyloid (Aβ) can accumulate in Type 2 diabetes (T2D) and Alzheimer’s disease (AD) brains and evidence suggests that interaction between the two amyloidogenic proteins can lead to the formation of heterocomplex aggregates. However, the structure and consequences of the formation of these complexes remains to be determined. The main objective of this study was to characterise the different types and morphology of Aβ-hIAPP heterocomplexes and determine if formation of such complexes exacerbate neurotoxicity. We demonstrate that hIAPP promotes Aβ oligomerization and formation of small oligomer and large aggregate heterocomplexes. Co-oligomerized Aβ42-hIAPP mixtures …

Cyber-Security Constrained Placement Of Facts Devices In Power Networks From A Novel Topological Perspective, Hossein Parastvand, Octavian Bass, Mohammad A. S. Masoum, Airlie Chapman, Stefan Lachowicz

Research outputs 2014 to 2021

Optimal placement of flexible AC transmission systems (FACTS) devices and the cyber-security of associated data exchange are crucial for the controllability of wide area power networks. The placement of FACTS devices is studied in this paper from a novel graph theoretic perspective, which unlike the existing approaches, purely relies on topological characteristics of the underlying physical graphs of power networks. To this end, the maximum matching principle (MMP) is used to find the set of required FACTS devices for the grid controllability. In addition, the cyber-security of the most critical data related to the FACTS controllers is guaranteed by introducing …

Robust Placement And Sizing Of Charging Stations From A Novel Graph Theoretic Perspective, Hossein Parastvand, Octavian Bass, Mohammad A. S. Masoum, Airlie Chapman, Stefan Lachowicz

Research outputs 2014 to 2021

This paper proposes analytical approaches to extend the capacity of existing networks of electric vehicles (EVs) by placement of additional charging stations (CSs) as well as determining the sizes of existing and new CSs in order to handle future expansions of EVs. The EV flow at CSs is modeled by a graph where nodes are potential locations for CSs and edges are uncertain parameters representing the variable EV flow at CSs. The required extra CS locations are explored by transforming the CS placement problem into a controllability framework addressed by maximum matching principle (MMP). To find the sizes of each …

Explaining Lecture Attendance Behavior Via Structural Equation Modeling: Self-Determination Theory And The Theory Of Planned Behavior, Ross C. Hollett, Gilles E. Gignac, Shinae Milligan, Paul Chang

Research outputs 2014 to 2021

Some research suggests that university lecture attendance positively correlates with academic performance. Although there are several motivational pathways which may explain attendance, few studies have examined the psychosocial factors leading to student attendance intentions and behavior. Consequently, we evaluated via structural equation modeling (SEM) two prominent motivational theories to help explain lecture attendance: Self-Determination Theory (SDT) and The Theory of Planned Behavior (TPB). Undergraduates (N = 288) from two universities completed pre-semester motivation measurements and post-semester estimates of attendance. Student grades were also examined. SDT was not found to be an accurate model of attendance intentions or behavior. By …

A New Development In Front Group Strategy: The Social Aspects Public Relations Organization (Sapro), Rachel Pietracatella, Danielle Brady

Research outputs 2014 to 2021

Increased pressure on risk industries to reduce their negative impact on society has resulted in an increasing volume of “risk” and “responsibility” communications from interest groups known as Social Aspects Public Relations Organizations (SAPROs). SAPROs have been criticized for being the “front groups” of risk industries (e.g., the tobacco, gambling, sugar, and alcohol industries). Operating within the neoliberal policy framework, SAPROs seek to forestall regulation and prioritize industry profits over public health. Building on risk industry research from the public health sphere, this article examines the SAPRO phenomenon and situates it in the political public relations (PR) literature. Specifically, it …

Dirkzwager, Kate Dolan, Seena Fazel, Colin Fischbacher, Margaret Giles, Lesley Graham, David Harding, Yen-Fang Huang, Florence Huber, Azar Karaminia

Research outputs 2014 to 2021

Introduction More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance. Objectives To comprehensively document the incidence, timing, …
