This article, we present a thorough and straightforward hydrothermal method towards the production of reduced graphene oxide templated MIL-53(Fe) hybrids RGO@MIL-53(Fe). The structural characteristics of created hybrids were identified by using BET, FESEM, powder X-ray diffraction, and FTIR techniques. Methylene blue (MB) dye (a model water pollutant) was used to evaluate H2O2-assisted photo-catalytic efficiency of RGO@MIL-53(Fe).

Brachytherapy is a form of radiotherapy in which radioactive sources are placed at short distances from, or even inside the target volume. The use of high dose rate brachytherapy is a widely accepted and clinically proven treatment for some stages of prostate cancer. The aim of this project was to investigate potential improvements on two of the most important aspects of high dose rate (HDR) and pulsed dose rate (PDR) prostate brachytherapy - prostate definition and treatment delivery verification.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The aim of this thesis was to investigate and characterise the effect on electron dosimetry that localising different forms of bolus, both approximately tissue equivalent and non tissue equivalent, in a non conventional, although reproducible locations, (ie not on the phantom surface). A series of experiments were derived to compare the differences in beam characteristics between the recognised conventional method of locating bolus on the surface to that of bolus supported by the Low Melting point Attenuator (LMA) Electron insert.

Tensegrity is a structural system constructed of tensile cables and compressive bars. This thesis proposes several general methods for creating tensegrity structures. The author has developed new methods for creating specific tensegrity cells and the corresponding computer code. Furthermore, the author has constructed various physical models to validate the methods. A proposal for an observation tower on top of the Eureka building in Melbourne has also been devised by the author.

The document will be structured as follows: In Chapter 2 outline the methodology, discussing the computational techniques used to evaluate the interaction energies and evaluating the construction of the TT and D3(BJ) correction terms. Chapter 3 attempts to establish a foundational understanding of how these methods model vdW interactions by evaluating the performance of the corrected and uncorrected HF and DFT methods in comparison with CCSD(T) energies for a selection of inert gas dimers, and simple molecule-molecule interactions.

This research project "Prioritisation in infrastructure asset maintenance" aims to develop a reliable and accurate decision-making method for improving the maintenance prioritisation of irrigation infrastructure. The method should utilise agreed evaluation criteria, based on existing organisational policies and risk frameworks, and real-time data representing the physical condition of assets to prioritise them for maintenance.

: Fluid vents in the Sea of Marmara were discovered and investigated by several studies. In this paper, a numerical model is created for the first time to determine the possible transport mechanism behind those fluid emissions at the seafloor. The finite volume method is used for numerical simulations by implementing a commercial finite volume code, ANSYS-Fluent. The thermal and physical rock properties used in our models are taken from previous studies.

Lithium (Li) is the lightest metal, has unique physicochemical properties and is the main component of lithium-ion batteries. Rechargeable lithium-ion batteries play a very important role in maximizing the performance of electric devices and vehicles. It is predicted that the metal and mineral demand for lithium-ion batteries will increase 56 times by 2050. In order to meet the increasing demand, in addition to known methods, lithium recovery from geothermal waters has become a very popular research subject.
