Scope
My research activities at JNCASR encompass both experimental and numerical/theoretical aspects of multiphase flows. In particular, my focus is on understanding the evolution of different types of hydrodynamic instabilities such as Rayleigh-Bénard-Marangoni convection [1] and Faraday instability [2] in micro-gravity conditions. In addition, our group focuses on acousto-fluidic interactions and complex fluids. We also actively work on the development of new computational algorithms for accurately predicting multiphase flows [3].

Scope
I work at the intersection of mechanics, materials, and physics to conduct research into nanotribology (the atomic-scale origins of friction, adhesion, lubrication, and wear), nanomechanics, nanostructured materials, surface science, and scanning probe microscopy (SPM) including in situ methods. My primary focus is on using SPM and other surface science and material characterization techniques to probe the fundamental nature of materials in contact, and to apply the results to applications at the nano, micro, and macroscale. Recently I have focused extensively on the science and technology of ultrahard carbon-based thin films, ultrathin materials such as graphene, the role of environment (water and temperature) and friction and wear, and functional mechanisms of lubricant additives.

Scope
Studies of surface melting of ice have a long history going back to the pioneering idea of Michael Faraday in 1842. However, despite long term efforts lasting more than one century and a half, understanding its underlying mechanism still remains an elusive and challenging research topic. In addition, surface melting of ice is also recognised to be a key player involving various natural phenomena spanning from making snowballs and slippage on ice surfaces to electrification of thunderclouds and the destruction of ozone. Therefore, the importance of the fundamental understanding of surface melting is not limited only to condensed matter physics. In this study, with the aid of a new in-situ approach developed by us, we propose a new scenario of the thermodynamic origin of surface melting on ice crystal.

My reseach interest is function of water in crystal growth and dissolution process. I mainly use frequency modulation atomic force microscopy (FM-AFM) to visualize the solid surfaces and solid-liquid interfaces with atomic/molecular resolution. We recently aim to reveal the mechanism of ion exchange on clay mineral surfaces, the effect of electrolytes on transition of lipid bilayer, and the control of polymorphism of calcium carbonate crystals in biomineralization by nanoscopic in situ observation.
