Controllable transportation of bubbles in surfactant or aqueous is very important in daily chemical products, food fermentation,mineral flotation and other fields. However, bubbles are mainly dominated by buoyancy and move upward in solution, which makes the manipulation of bubbles difficult. Although some progress has been made in controlling underwater bubbles,achieving continuous transportation and collection of underwater bubbles without relying on external forces is still a great challenge. To this end, we bionically designed a flexible polydimethylsiloxane(PDMS) porous surface with dual-Janus characteristics. Namely, a porous PDMS membrane integrating structural gradient and wettability gradient realizes the underwater anti-buoyancy unidirectional transportation of bubbles without external force input, and possesses the capability of underwater gas anti-buoyancy transportation and storage. This work provides inspiration and direction for the development and design of underwater gas transportation and storage devices and provides innovative thinking for the implementation of seabed carbon dioxide storage technology.

The oxygen transportation from surrounding air to coating cracks is an important factor in the oxidation and ignition of titanium alloy. In this work, the oxygen transport and surface oxidation of titanium in inclined cracks of coating under parallel airflow are studied with the lattice Boltzmann method(LBM).A boundary scheme of LBM about surface reaction is developed. The conversion factors are utilized to build the relationship between the physical scale and the lattice scale. The reliability of the LBM model is validated by the finite element method(FEM). The results show that the convective mass transport driven by the surrounding airflow and the vortex structure formed inside the crack are the two significant factors that influence the oxygen transport in cracks. The convective mass transfer plays a major role in oxygen transport when the inclination angle of the crack is small. For the cases with a large inclination angle, the oxygen transfer from the top to the bottom of the crack is mainly controlled by mass diffusion mechanism. The oxygen concentration in inclined cracks is generally less than that in vertical cracks, and oxidation and ignition of the substrate titanium might be more likely to occur in relatively vertical cracks.

Researches have investigated the formation, transportation and spreading of bubble on solid surface with specific wettability. However, bubble transfer on wettability-heterogeneous surfaces has been rarely reported, which also plays significant role in water electrolysis, heat transfer, micro-bubble collection, *** this work, we carefully investigate the behavior of bubble transfer from the aerophobic or aerophilic region to the superaerophilic region through fabricating the wettability-heterogenous surfaces. Surface energy was elucidated to be transformed to the kinetic energy during bubble transfer process. Theoretical analysis on the average velocity of bubble transfer was consistent with the experimental *** influence of wettability of solid substrate, bubble volume and superaerophilic stripe width on bubble transfer are carefully investigated. Moreover, wettability-heterogeneous surfaces were explored to be applied in micro-CO_(2) bubble collection and H_(2) bubble removement in water splitting.
