“…Solid lines indicate the reduction slope, i.e. the change in values with increasing reduction of N 2 to N 2 O; reduction slopes are between 0.2 and 0.5 according to fractionation factors from Ostrom et al ., Well and Flessa, and Jinuntuya‐Nortman et al . If solely denitrification with reduction takes place, the measurements will fall into the area between the solid lines.…”

“…Another factor influencing the microbial consumption of soil‐borne N sources could be secretion of C‐rich mucus by earthworms . Burrow walls gain stability through mucus infiltration, which also increases moisture within the drilosphere, and any N 2 O produced in these microsites could rapidly leave the soil via large pore systems.…”

“…The scalelike unit structure of the pangolin can achieve effective drag reduction. According to the results of previous work by our research group [9,10], the bionic digging shovel inspired by the structure of pangolin scale units ( Figure 2) were designed (labeled S-U-S) according to the structure and scale of pangolin scales. Besides, an ordinary plane shovel (labeled O-P-S) was designed as the comparison and the outline structure of the O-P-S is shown in Figure 3.…”

The resistance of ordinary potato digging shovels can increase dramatically when used in a clay soil because of the adhesion between the soil and shovel. In this paper, a new type of bionic potato digging shovel was designed to decrease adhesion. The bionic structural elements, i.e., scalelike units (S-U) were applied to the potato digging shovel with inspiration from pangolin scales. The discrete element method (DEM) considered cohesion was used to simulate the drag reduction performance in clayey soil conditions. An ordinary plane shovel (O-P-S) was used for comparison. Three indicators (total force, draft force and compressive force) were used to characterize the drag reduction performance. The effect of the design variables of the bionic structures (length [l] and height [h]) and the transversal and longitudinal arrangement spacing (S1 and S2) of the structures on the drag reduction performance were analyzed. The results showed that the drag reduction performance of the bionic shovels with suitable parameters was better than that of the O-P-S. The best bionic sample labeled as a bionic prototype had a 22.26% drag reduction rate during the soil bin test and a 14.19% drag reduction rate during the field test compared to the O-P-S.

Engineering surface wettability is of great importance in academic research and practical applications. The exploration of hydrogel‐based natural surfaces with superior properties has revealed new design principles of surface superwettability. Gels are composed of a cross‐linked polymer network that traps numerous solvents through weak interactions. The natural fluidity of the trapped solvents confers the liquid‐like property to gel surfaces, making them significantly different from solid surfaces. Bioinspired gel surfaces have shown promising applications in diverse fields. This work aims to summarize the fundamental understanding and emerging applications of bioinspired gel surfaces with superwettability and special adhesion. First, several typical hydrogel‐based natural surfaces with superwettability and special adhesion are briefly introduced, followed by highlighting the unique properties and design principles of gel‐based surfaces. Then, the superwettability and emerging applications of bioinspired gel surfaces, including liquid/liquid separation, antiadhesion of organisms and solids, and fabrication of thin polymer films, are presented in detail. Finally, an outlook on the future development of these novel gel surfaces is also provided.
