- Interfacial transfer at mesoscale is a common issue for all the multi-phase chemical processes, and the related study remains as a scientific challenge due to the complexities. Investigating the interfacial interactions at mesoscale to find out the regulation strategies is the key to realize process-intensification of mass-transfer and reaction for the advanced chemical industries. To accurately describe the behavior of fluids at the interface, a new molecular thermodynamic model that can describe the complex fluid-solid interface interaction. When the molecular thermodynamic modeling method is extended to the nano-micro interfacial transfer needs to be developed, calling for the coordination of advanced experiments at nano-micro scale and molecular with molocular thermodynamic modelling. Atomic force microscopy (AFM), which possess the sensitivity down to nanoscale, can directly obtain the interfacial interaction at nano-micro scale. The quantification of AFM-measured forces can be used to construct the coarse-grained molecular model and describe complex interfacial interaction. Then, the coarse-grained molecular model can reveal the molecular thermodynamic mechanism of nano- and micro- interface transfer, realizing quantitative prediction.

- The heat generation and transfer process of self-lubricating materials and friction materials was quantitatively described from the fundamental principle of non-equilibrium thermodynamics. The effect of friction coefficient and thermal conductivity on the contact temperature of materials was studied, and the finding could guide the design of polymer composites. For the self-lubricating materials, the frictional heat generation and transfer process was assumed to be two processes in series. The frictional heat generated was the key controlling factor for stable operation of the friction system. For the friction materials, frictional heat transfer process was assumed to be heat transfer and heat distribution, two processes in parallel, and it was required to reduce thermal conductivity of the brake pads in order to lower contact surface temperature.

- Choline-based deep eutectic solvents (DESs) are considered as a new class of ionic liquids. Comparing to traditional ionic liquids, choline-based DESs are low-toxic, biodegradable, and the price is generally low, which make them more and more attractive in green chemistry and industrial chemistry. In the current work, the properties of choline-based DESs, such as freezing point, melting point, solubility, viscosity, surface tension and conductivity, were collected and summarized. The dependences of these properties with different factors, such as temperature, mole ratios and water content, and the models which can be used to predict the properties were studied and discussed. The applications of choline-based DESs in the area of lubrication, functional material preparation, electrochemistry, organic synthesis and catalytic conversion of biomass were introduced. Finally, the problems and difficulties in research and applications were illustrated and then prospective was provided.
