Nanoporous materials such as Metal-Organic Frameworks (MOFs) have their applications in mechanical energy absorption. For example, MOFs can offer extremely small hydrophobic pores that are comparable to the size of water molecules, squeezing liquid water into these tiny nanopores can create large solid-liquid interfaces and dissipate huge amount of mechanical energy. Flexible MOFs can also have structural transitions under mechanical pressure to absorb energy. Mechanical energy absorption through these mechanisms can be amplified by their large surface area and porosity, leading to a much higher efficiency than conventional materials.
This research is highly interdisciplinary, so we invite applications from candidates across all relevant areas, including but not limited to:
- Chemistry: NanoporousMaterial Synthesis (MOFs, COFs, zeolites, polymer, silica), Crystallography, Spectroscopy
- Physics: Nanofluidics (nanoscale water), Molecular Dynamics, Thermodynamics
- Materials: Colloids, Gel, Polymer
- Mechanics: Solid Mechanics, Impact Mechanics, Vibration, Dynamics, Acoustics, Rheology
- Engineering: Mechanical Design, Mechatronics, Sustainability
Applicants should have 1st class (or equivalent) in their first degree in one of the disciplines above. Those wishing to apply should email Dr Yueting Sun with CV.
