  "Exploring the interplay of water’s peculiar properties with solvation"
  Prof. Fivos Perakis, Physics Department, Stockholm University

The intricate interaction between water and various molecular components often results in complex molecular dynamics; however, a comprehensive mechanistic description of these solutions is lacking. For instance, it remains unsolved how nanometer-scale transient structural heterogeneity, which arises from weak intermolecular interactions, relates to the overalls tructural solution dynamics of biomolecules. Are water's anomalous properties directly involved in life processes? In my group, we investigate the interplay of supercooled water's peculiar thermodynamic and dynamic properties with solutes. Here, I will give an overview of the group's recent activity, highlighting our studies on nanoparticle diffusion in supercooled water [1,2] and hydrated protein spatiotemporal fluctuations [3,4]. Finally, I will present recent unpublished results on rapidly supercooled microdroplets of aqueous mixtures that provide new insights into water's anomalies and its interplay with solvation.

  "Development of the Nanocarbon-based Electrode materials for Water Electrolysis and Li-ion Batteries"
  Prof. Masanori Hara, Surface Science Lab, Toyota Technological Institute

In recent years, environmental issues of global warming have become significant topics. To overcome the environmental problems, effective utilization of renewable energies such as solar and wind energy, for example, the conversion and storage of surplus energies, is a critical issue. One of the prospective candidates is production of hydrogen via water electrolysis in polymer electrolyte water electrolyzer (PEWE). Another realistic candidate is large-scale energy storage systems using Li-ion batteries (LIB). In our study, we have developed novel electrode materials using nanocarbons such as IrO2 catalysts supported on heteroatom-doped graphene for PEWE and vertical-aligned carbon nanotube (CNT)-modified Cu electrodes for LIB to improve the performance of these electrodes.
