Surgery with rockets

Self-propelled nano/microscale rockets have been developed that consume locally supplied chemical fuels to generate thrust, analogous to how large rocket engines ignite onboard propellants. Such rockets offer tremendous advantages as nano/microdevices. They can be designed for low or high velocities (up to 1000 body lengths/sec), can tow large loads, have remarkable design flexibility, and allow surface functionalisation with nanomaterials and biomolecules.1,2Unlike their macroscale counterparts, these rockets have the advantage of harvesting their chemical fuel directly from their surrounding environment. In …

Patient-specific modelling of atherosclerosis

Rupture of atherosclerotic plaques without warning is responsible for most acute cardiovascular syndromes such as heart attack and stroke, and many victims who are apparently healthy die suddenly without prior symptoms. Such deaths could be prevented by surgery or alternative medical therapy if vulnerable plaques were identified earlier in their natural history. New diagnostic screening methods are urgently needed to assess plaque vulnerability to avoid such acute events.

Treatment of mine wastewaters

Mining processes create wastewater that is typically unsuitable for release into the environment without some form of treatment. Treatments will vary depending on the composition of the wastewater and where the water is to be reused.

Plasma mutagenesis

Microbial cells are of special significance for biotechnological applications, where bacteria and yeasts are used for many biotechnological tasks, including biofuel production, synthesis of commodity chemicals, and production of industrial and biopharmaceutical proteins.Mutagenesis is an important technique in microbial engineering whereby DNA mutations are deliberately introduced into the microorganism to produce mutant genes, proteins, and strains of bacteria. For example, the mutated gene may produce a mutated protein the properties of which, e.g. its thermostability, optimum pH and specific activity, …

Epitaxial growth of 2D heterostructures on SiC for electronics and gas sensing

Graphene has attracted a great deal of interest due to its remarkable electronic, optical and mechanical properties, however the absence of a bandgap limits its use in many applications. Future applications in nanoelectronics and gas sensing will depend critically on the development of novel approaches to introduce a bandgap while preserving carrier mobility, for example by creating heterostructures of graphene with other two dimensional (2D) materials with complementary properties.This project will explore the heteroepitaxial growth of new 2D materials to …

Secondary aerosol formation from engine exhaust emissions

In Oct 2013 WHO and their International Agency for Research on Cancer classified particulate matter and outdoor atmospheric pollution as carcinogenic to humans. The main contributor to high atmospheric pollution episodes in urban environments are secondary organic aerosols (SOA), or photochemical smog, generated in the atmosphere through oxidation of reactive volatile gasses, primarily coming from traffic.Estimates point out that diesel vehicles are responsible for 65% to 90% of the secondary pollution formed from vehicle emissions. The origin of 75% of …

Advanced photoresists for 3D laser lithography

Some estimates state that 30% of all manufactured goods will be 3D printed in 2030. A particular type of 3D printing is 3D laser lithography with which micro- and nano-sized structures can be prepared. Such structures find wide ranging applications in meta-materials functioning as invisibility cloaks or scaffolds for single (stem) cell interrogation. Today’s inks for 3D printing, however, only allow one material property to be written with one laser wavelength. This project will develop – in close collaboration with …

Krazy-adhesives: development of glues that work underwater

Almost all current adhesives loose activity in water. However, in many applications especially in medical, things need to glue together under wet conditions.The project will tackle this challenge using biomimetic approach. In nature, several water species secrete protein matrices that are used for anchoring under the water such as mussels or sandcastle worm. For example, it has been recognized that polydopamine was crucial in the attachment of mussels to surfaces and sandcastle worm uses tiny amounts of a special protein …

Carbon-based supercapacitors from graphene and 2D materials

With the exponentially growing portion of electricity generated from renewable resources (solar, wind, and tidal power) in total electricity production throughout the globe, the mission of implementing environment-friendly energy storage technology is even more important to the future sustainable economy.Supercapacitors are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources. Graphene and its compounds, graphene oxide, nanotubes, are targeted as materials to increase the charge …
