Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in res ....Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in response to ventilation and dynamic wastewater and atmospheric conditions, enabling model-based sewer ventilation design and operation. The project also aims to deliver novel, field-demonstrated ventilation strategies. The project findings will be incorporated in the Australian ventilation design and operation guidelines.Read moreRead less

Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on ....Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.Read moreRead less

Molecular mechanisms of novel bacterial copper defense proteins. This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity.

This project aims to reveal molecular and cellular mechanisms used by bacteria to neutralise the destructive effects of copper. Copper is an essential trace element in living systems. It is toxic to bacteria and so plays a vital role in nutritional immunity. To counteract copper toxicity, bacteria have evolved defense mechanisms. The project will investigate a novel but poorly understood class of bacterial proteins, the suppressor of copper sensitivity proteins, that contribute to this key virulence trait. The expected outcomes will be fundamental new knowledge of metallo-protein diversity, bacterial virulence mechanisms, and membrane protein function with potential impact on health, environment, and biotechnology.Read moreRead less
