[foreword] the liquid is directional depart in the sources of energy, small fluid, grease from transport and water collects the application with wait for a domain to have fundamental. The symmetry that one-way transport needs groovy liquid to break a liquid to flow through the input of outside energy and the Za Ding effect that overcome structural surface blemish to cause. The existence in nature a lot of moving plant, for instance common nepenthes, cacti, desert beetle is mixed lizard, they rely on the special small structure of oneself surface ably to control the directional movement of droplet, live below harsh environment thereby. However, operating mode of actual project application is mixed, involve complex interface and heterogeneous to change process. Such, how can development can surmount nature and realize directional passive in interval of field of wide chart temperature the artificial stuff system from transport of drive, Sunday run is the main challenge that faces at present. From transport in the droplet of fore-and-aft direction this researchs a field, a crucial science and engineering issue are how to design as new-style as development copy to give birth to material to break the trends with solid fluid inherent interface to contact the physical limit of time. Exceed infiltration material traditionally (lotus leaf effect) basically be based on structure of small accept rice, and mechanical performance is weak, outdoors be able to bear or endure await gender, chemistry stability and be able to bear or endure performance of damp and hot is poor, and be hard to machine. Wang Zuan opened a group to develop to be based on inferior the special rule of millimeter measure exceeds infiltration system, discover the phenomenon of bounce of droplet cake shape that exceeds range of scanty water meter first in the world, build the kinetic model that droplet moves, announce collision droplet is played without systole from the mechanism, overturned 130 years to come the groovy understanding that people contacts to trends of solid fluid interface. Be based on this model to design preparation all sorts of inferior millimeter blame convention exceeds infiltration surface, shortened droplet and the physical limit that exceed the osculatory time of infiltration surface 80% (Nature Physics, 2014, 10, 519, bibliographical reference [1] ) . This job also regards window as the report in Nature Physics. Additional, be based on structure of radian of jade lotus surface this is inspired, developed waviness millimeter form alterable radian copy is unripe exceed infiltration surface, put forward to exceed infiltration surface droplet asymmetrical bounce is academic, the academic limit that engages solid fluid time shortens 40% above (Nature Communications, 2015, 6, 10034, bibliographical reference [2] ) . In the meantime, have lotus leaf effect and common nepenthes effect the couple of machine, announced on liquid film kind the physical mechanism of lotus leaf effect (Nature Communications, 2015, 6, 10034, bibliographical reference [3] ) , offerred new thinking to develop special rule to exceed infiltration surface. From drive transport in the droplet of transverse direction this researchs a field, wang Zuan opened group system to consider how to pass control surface wellability and design to change those who will realize droplet to fall in mixed operating mode to transmit change with energy. Below microtherm, they formulate the strategy of shape of synchronous aggrandizement film and drop record condensation, successful development goes close scanty jumbly structure of small accept rice, the formation that synchronism quickens droplet and leave from drive, raise the surface to pass thermal efficiency considerably (Advanced Functional Materials, 2011, 21, 4617, cover, bibliographical reference [4] ; ACS Nano, 2015, 9, 71, cover, bibliographical reference [5] ) . Send the job on Advanced Functional Materials to be commented on to be exterior project by the editor of Nature Physics among them since the domain is long-term most original considers to work. Below high temperature, what as a result of Laidufuluosite in the light of high temperature condition the phenomenon brings about is low send thermal efficiency issue, clever design asymmetrical exterior structure, use exterior structure and temperature two-way adjusting control, revulsive droplet transfers the area with heat exchange high efficiency, avoid to appear the boiling crisis in conducting heat (Nature Physics, 2016, 12, 606, bibliographical reference [6] ) . Below normal temperature, be based on sensitive plant from fold effect, developed passive from drive film, fluid physical ability is rapid only way is quick spread out (Science Advances, 2016, 2, e1600417, bibliographical reference [7] ) , this job is regarded as to study window reports by Nature and Nature Physics. [achievement brief introduction] recently, king of college of Hong Kong city gets task group to give birth to domain of exterior liquid drive to gain revolutionary headway in small accept Mifang. This research achievement with " Topological Liquid Diode " (develop attacks fluid diode) title published in Science on October 27, 2017 child print Science Advances (2017, 3, eaao3530, bibliographical reference [8] ) . College of Hong Kong city is the first unit that finish, cooperative unit has university of oil of small system of Shanghai of Chinese Academy of Sciences and IT institute, China (Hua Dong) , Caspian university of university of British Nuo Sang Biya and United States. King of college of Hong Kong city gets Manoj K of Caspian university of associate professor and United States. Chaudhury teachs the newsletter writer that is a paper. Besides infiltration data system and liquid exceed to gave birth to a domain to gain a series of headway from the mechanical copy such as transport in special rule besides, wang Zuan opens research the group also was fighting the domain such as adhere of frozen, anti-fouling, surface to begin a series of research. [article window] the Sunday run to realize a fluid, directional, transmit from drive, we introduced develop to attack the concept of fluid diode. Through designing structure of unique small accept rice, reduce the flow resistance of a direction, increase the flow resistance that counters direction at the same time, both between perfect be united in wedlock and each other noninterference, the liquid that achieved long distance is transmitted from drive. Diode broke through this fluid to infiltrate before the spread out speed limit of the transmission length limitation of gradient drive and asymmetry structure drive, huge raised a liquid directional transmission efficiency. This fluid diode has extensive catholicity and stability, can transmit character the liquid of each different (low surface can liquid and tall agglutinant liquid) , can transmit a liquid along different method, can overcome gravitational transmission liquid, can overcome temperature gradient to transmit even. So superior performance makes its are in conduct heat pass qualitative, heterogeneous shedding, water to collect, the liquid is transmitted, the domain such as refrigeration of medicine of small fluid, biology, electron is having tremendous applied perspective.
