New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriat ....New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriate rigidity and toughness, and stimulate better bone growth at the interface. In this way the implant should be much longer lasting and the need for undesirable revision surgery reduced. The processing technique proposed could also be a useful platform coating technology in a number of other industries.Read moreRead less
New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high tec ....New Types of Biomimetic Nanostructured Adhesives. Adhesives are one of the main ways in which we join materials, and have many advantages over other methods of joining. In this work we will make a new class of adhesive using nanotechnology that attempts to copy the very fine-haired feet of animals such as geckos who can stick to almost any surface, under most conditions. We will make these adhesives over large surface areas, and thus they will have commercial possibilities in a range of high technology industries, as well as in harsh environments. Because we will be able to manipulate the structure and observe property changes, it should also give us a greater insight into the adhesion mechanisms used by many small animals and bugs.Read moreRead less
The development of super-toughened epoxies using a novel nanomaterial. Epoxy resins are widely used as structural adhesives and coatings in engineering structures. This project will address the problem of the intrinsic brittleness of epoxy by making it significantly tougher with superior performance and cost-effectiveness.

Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of ....Novel Waterborne Multifunctional Sealer for Asphalt Pavement. One of the long-term challenges and most serious problems faced by the asphalt surfacing and road construction industry is the rapid deterioration of asphaltic surfaces to the extent that they become unfit/unsafe for use in short time. The length of the Australian local government road system is approximately 810,000 kilometres and currently approximately $2,460 million/year is spent on road maintenance; the replacement value of the road asset exceeds $106,000 million. Thus providing satisfactory tough protective shield on asphalt pavements that locks out destructive elements and provide long-term protection is of enormous economic importance and national/community benefit.Read moreRead less
Functional Renewable Plastics: Developing Novel Polysaccharide, Protein and Natural Polyester Based Polymer Nanocomposites. Biopolymer based plastics (eg starch and proteins from plants; polylactic acid from wastes) are made from renewable sources and are readily biodegradable, making them good substitutes for synthetic plastics for uses like packaging and agricultural film.
Some biopolymer plastics properties (eg water migration barrier, strength) are not as high as synthetic plastics.

Biopolymer based plastics (eg starch and proteins from plants; polylactic acid from wastes) are made from renewable sources and are readily biodegradable, making them good substitutes for synthetic plastics for uses like packaging and agricultural film.
Some biopolymer plastics properties (eg water migration barrier, strength) are not as high as synthetic plastics. Creating nano-biocomposites (biopolymer plastics mixed with low levels of nano particles) will improve the properties of biopolymer plastics, giving novel materials that can be substituted for synthetic plastics in a wider range of applications.
These products will reduce our environmental impact, and also create economic benefits from novel, high-value nano-biocomposites.Read moreRead less
