One (1) post-doctoral position is available in Prof. Barbaros Özyilmaz’s group at the National University of Singapore (NUS) to advance on the project that focuses on synthesis of novel foam structures, suitable for many different applications. Our research team’s principal goal is to specifically target the scientific and technological bottlenecks which are preventing most.
Despite having several applications, a fully accessible pore structure with high surface area and material density has been very difficult to achieve. There is always a tug of war between material density and accessible surface area, which has been so far the biggest obstacle in obtaining high volumetric surface area. Volume/size matters the most, as that defines the compactness. This has remained as a challenge, because of lack of control in spatial arrangements of nano particles. Porous materials mainly end up either with the following combinations; either high surface area with poor density or dense material with poor accessibility.
In our lab, we have developed a bottom-up approach to synthesise novel nano-structures, leading us to a unique, controlled spatial arrangement of nano-particles, which in turn has provided us the key to achieving the highest volumetric surface area reported so far for carbon. This approach enabled us to create carbon foams to target very specific applications and tailor material properties accordingly. For example, these carbon foams as ultra-thick electrodes for supercapacitor applications resulted in very high energy density and high power devices, thanks to the hierarchical structure of the pores made by nano-particles of specific aspect-ratios. Also, in the electrode developed for Si-based battery anodes, by introducing a novel elastic material, we have obtained excellent structural stability under high lithiation rate. Simultaneously, we are in collaboration with a key industry player in supercapacitors, muRata Manufacturing Co. Ltd.
We are now using this unique technique with other 2D materials, and we’re now synthesising unique porous materials out of them, which would open up potential new applications. such as solar steam generation, hydrogen evolution, hybrid-supercapacitors, Li-air batteries, carbon capture and storage (CCS), water disinfection and desalination applications.
In this frame, we are looking for a highly motivated and creative researcher with experience in energy storage applications (supercapacitors/batteries), characterization nano-porous structures, nanocarbon material synthesis.
In this frame, we are now seeking for candidates holding (or about to hold) a PhD in Physics, Material Science, Nanoscience and Nanotechnology or related disciplines. The ideal candidate will demonstrate:
- Proven track record of excellence in experimental research, preferably experienced with supercapacitors/batteries characterizations and related material development/synthesis and characterizations.
- Experience in using multiple techniques to characterize porous structures including BET surface area measurements.
Informal enquiries may be directed to Prof. Barbaros Özyilmaz email@example.com.
Formal submissions should include: Cover letter, Curriculum Vitae, the contact details of three potential references. (Potential candidates will be contacted by phone and invited for an interview.)
The position is available for 1 year and can be extended based on performance. Selected candidate will receive a salary package and globally competitive benefits (health insurance, housing, travel, and relocation allowance). Salary will be decided depending on previous experience.
The call will remain open until suitable candidates are identified. We also welcome qualified candidates to conduct 4 year PhD degree research program (http://staff.science.nus.edu.sg/~barbaros/open.html)
