    Epoxy resins show a combination of thermal stability, good mechanical performance, and durability, which make these materials suitable for many applications in the Aerospace industry. Different types of curing agents can be utilized for curing epoxy systems. The use of aliphatic amines as curing agent is preferable over the toxic aromatic ones, though their incorporation increases the flammability of the resin. Recently, we have developed different hybrid strategies, where the sol-gel technique has been exploited in combination with two DOPO-based flame retardants and other synergists or the use of humic acid and ammonium polyphosphate to achieve non-dripping V-0 classification in UL 94 vertical flame spread tests, with low phosphorous loadings (e.g., 1-2 wt%). These strategies improved the flame retardancy of the epoxy matrix, without any detrimental impact on the mechanical and thermal properties of the composites. Finally, the formation of a hybrid silica-epoxy network accounted for the establishment of tailored interphases, due to a better dispersion of more polar additives in the hydrophobic resin

    Towards Detection of Redshifted 21-cm Signal from Cosmic Dawn and Epoch of Reionisation

    Get PDF
    The redshifted 21-cm signal from neutral hydrogen has the potential to provide valuable information on the the periods of cosmic dawn and epoch of reionisation (CD/EoR). The sky-averaged or global component of the 21-cm signal is expected to be observable as a distortion to the low frequency radio spectrum. This thesis is on experimental techniques to detect the global 21-cm signal. Instrument descriptions, laboratory analysis, calibration and data analysis methods for two different instruments - SARAS-3 and SITARA - are provided. Advantages and challenges associated with each instrument are also discussed

    Integrated power/signal transmission for smart energy systems

    Communication technologies, especially wired technology, have developed considerably in terms of signal stability and communication speed. Conventional renewable energy generation units in traditional energy systems require additional communication devices to manage the renewable power generation equipment, which can raise the size and expenditure of the system. Additionally, although power line communication (PLC) can simplify system wiring by eliminating the requirement for communication cables, additional signal coupling devices are still needed to combine energy and signals. Therefore, it is significant to investigate a suitable transmission approach for energy and signals in smart energy systems (SESs). The purpose of this study is to analyse the feasibility of the integrated power/signal transmission (IPST) approach and to develop IPST-based converters for SESs. Firstly, state-of-the-art communication strategies including wireless and wired methods are reviewed and their advantages and restrictions are summarised in comparison. The review work demonstrates that it is essential to systematically analyse the possible signal modulation approaches for power converter implementations and extend IPST technology in AC power system applications. On this basis, this research then investigates the similarity between signal transmission and power conversion from a system architecture perspective and analyses the mechanisms of pulse width modulation (PWM) based signal modulation methods. Next, the integrated transmission approaches are verified through the buck converter, boost converter and cascaded H-bridge converter, and the simulation results demonstrate that the designed strategies have decent noise immunity. Finally, all the proposed IPST methods in different SESs are validated. In summary, the main achievements of this study are the analysis of the feasibility of various converters for IPST transmission and the extension of IPST technology to different SES applications
