Hybrid multiple-tube concrete columns incorporating composite materials. The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stre ....Hybrid multiple-tube concrete columns incorporating composite materials. The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.Read moreRead less
A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer proces ....A Novel Approach to Polymer/Nanosheet Composites and Their Fundamentals. Multifunctional Polymer/nanosheet composites have not yet been widely scaled up in polymer processing and composite industries mainly due to cost and inhaling hazard. This project proposes a novel methodology which embeds nanosheet preparation within polymer melt to both remove the inhaling hazard and lower the cost; the key is to develop two groups of nanosheet intercalation compounds which can expand at the polymer processing temperature, to exfoliate and disperse nanosheets in polymers. It is expected to generate new knowledge of the structure-property relationships and fracture mechanisms of these composites, for industry to scale up this technology and to develop new product.Read moreRead less
Conducting coatings for control and eradication of unwanted marine biofilms. Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them. To date, biofilm's detailed response to variations in electrochemically generated redox stress and shear is unknown in marine environments. The project aims at (i) developing novel electrically conducting carbon based paints that are stable in marine ....Conducting coatings for control and eradication of unwanted marine biofilms. Biofilms grow on all surfaces and environments posing environmental threats and economic issues globally, costing billions each year to those attempting to eradicate them. To date, biofilm's detailed response to variations in electrochemically generated redox stress and shear is unknown in marine environments. The project aims at (i) developing novel electrically conducting carbon based paints that are stable in marine environments and (ii) investigating how marine biofilms respond to these coatings. The expected outcome of this project is the development of a green alternative antifouling technology that can be used on demand in marine applications. This provides a new solution for controlling the biofouling of surfaces immersed in oceans.Read moreRead less
