Hydrazine hydrate (N2H4∙H2O) is considered an ideal fuel for fuel cells. Constructing a cobalt phosphide/cobalt (CoPx/Co) heterostructure can achieve efficient electrocatalytic activity for hydrazine oxidation reaction. Traditional strategies for constructing CoPx/Co heterostructures took less consideration on the exposure of the active sites. In this study, 3D nanoflower-like nano CoPx/Co heterostructures with highly exposed active sites were obtained on a nickel foam (NF) through a dual-component phosphating strategy, i.e., regulating the relative content of Co and Co(OH)2 with cathodic current density and utilizing the differences in their phosphating behaviors. The potential at 100 mA∙cm‒2 and Tafel slope of the optimized CoPx/Co(375)@NF …

Aluminium Oxide Particles-Containing Organogels For Cleaning Of Optical Glass Surfaces, Galina Vladimirovna Lyamina, Oksana Valerievna Dubinina, Alfa Edison I Lela
Journal of Metals, Materials and Minerals
Hypothesis: Some types of cleaning methods are not very effective and can actually increase damage to the optical parts being cleaned. As an alternative to these methods, we propose the use of gel-like substances to remove contaminants from optical surfaces. We have developed a method for cleaning optical glass surfaces that uses organogels, which are based on copolymers of methyl methacrylate and methacrylic acid. These organogels are loaded with polyethylene glycol, and aluminum oxide particles (Al2O3), which help to effectively remove contaminants without causing damage to the surface. Experiments: Al2O3 nanoparticles prepared by a Nano Spray Dryer were added to …

Return Serve: Exploring The Dialogism Of The Australia-China Relationship In Media Coverage Between 2020-2022, Jordan Hogan
Theses: Doctorates and Masters
Australia and the People’s Republic of China (PRC) have a dynamic bilateral relationship that is defined by interdependency and mutual political scepticism. This thesis provides an analysis of Australian and Chinese news media perspectives on this relationship. Via an in-depth examination of opinion pieces from national press, I map the significant developments of a period of deteriorating relations between 2020 and 2022. My study captures the more prominent, parochial and vitriolic media coverage of the unravelling relationship, and investigates the motivations, developments, differences, and similarities in the online publications of Australia’s national daily newspaper The Australian, and China’s Global Times. …
The Rise Of Women In Mining - How To Improve Inclusion And Diversity Through Organisational Programs, Ashley Mcgrath
The Rise Of Women In Mining - How To Improve Inclusion And Diversity Through Organisational Programs, Ashley Mcgrath
Theses: Doctorates and Masters
The inclusion and diversity (I&D) of women has become a priority for organisations due to the positive association with business performance and rising expectations of employees and shareholders for fair outcomes for all genders. Improving the I&D of women is also being driven by the evolving Australian legal framework which has heightened the responsibility of organisations regarding psychological safety and the prevention of sexual harassment and sex-based discrimination. Companies operating in male dominated industries in Western Australia (WA) are under particular pressure due to lagging performance in addressing equity issues at a state level. Existing research correlates the I&D of …
Optimal Bag Valve Mask Ventilation Efficacy Of Smart Bag Ventilation Compared To Traditional Adult And Paediatric Bag Valve Ventilation During Cardiopulmonary Resuscitation, Ian Dawson
Theses: Doctorates and Masters
Background: Out-of-Hospital Cardiac Arrest (OHCA) is one of the world’s leading causes of mortality. Survival rates are low, ranging from 3.1–20.4% internationally. The most effective oxygenation method for patients during pre-hospital cardiac arrest is ventilating using a self- inflating Bag-Valve-Mask (BVM). Yet, extensive research has identified a lack of compliance with ventilator guidelines during OHCA cardiopulmonary resuscitation (CPR). As a result, clinicians often ventilate patients too aggressively using the BVM, delivering breaths excessively higher than the International Liaison Committee on Resuscitation (ILCOR) recommended rate of 10 breaths per minute (BPM). Hyperventilation can lead to complications such as aspiration, barotrauma, and …
Early, Standardised, And Precise Treatment Of Copd Exacerbations And Covid-19, Sanjay Ramakrishnan
Early, Standardised, And Precise Treatment Of Copd Exacerbations And Covid-19, Sanjay Ramakrishnan
Theses: Doctorates and Masters
Background: Background Chronic Obstructive Pulmonary Disease (COPD) is a common chronic condition causing significant morbidity and mortality. Patients with COPD report sudden episodes of deteriorating respiratory symptoms called exacerbations, often presumed to be precipitated by infections. COPD is in the top 5 causes of death globally. COPD exacerbations drive a large proportion of these deaths. Despite this, there is no standardised model of care for the sickest patients who need hospitalisations for exacerbations. Meanwhile, treatment for COPD exacerbations continues to be guided by symptoms, instead of underlying biology. Most patients are treated with unnecessary and harmful systemic corticosteroids. During the …
Athlete Monitoring And Training Modification Decision-Making: Insights From High-Level Endurance Sports Coaches, Wouter Piet Timmerman
Athlete Monitoring And Training Modification Decision-Making: Insights From High-Level Endurance Sports Coaches, Wouter Piet Timmerman
Theses: Doctorates and Masters
Athlete monitoring technology has proliferated in the last decades. However, much of what is known about athlete monitoring tends to come from unpublished personal experiences and anecdotal information. In the last decade, considerable athlete monitoring research has been conducted, leading to multiple reviews and consensus statements mainly on athlete monitoring tools and methods. Recognising that athlete monitoring is a human-driven process, typically with the coach as the decision-maker, it is imperative to study coaches given their extensive knowledge and expertise. The overall aim of the thesis was to gain insights into why and how high-level endurance sports coaches use athlete …
