Gecko and many insects have adopted nanoscale fibrillar structures on their feet as adhesion devices. Here, we consider between a single fiber substrate by van der Waals or electrostatic interactions. For given contact area A , the theoretical pull-off force of is σ th where strength adhesion. We show that it possible to design an optimal shape tip achieve force. However, such tends be unreliable at macroscopic scale because sensitive small variations in shape. find robust shape-insensitive...
We report damage-healable supramolecular silicone coatings with high adhesion to solid and low oils.
Abstract There is ever-increasing interest yet grand challenge in developing programmable untethered soft robotics. Here we address this by applying the asymmetric elastoplasticity of stacked graphene assembly (SGA) under tension and compression. We transfer SGA onto a polyethylene (PE) film, resulting SGA/PE bilayer exhibits swift morphing behavior response to variation surrounding temperature. With applications patterned and/or localized tempering pretreatment, initial configurations such...
Abstract The sodium‐ion battery is a promising technology owing to its low price and high abundance of sodium. However, the sluggish kinetics sodium ion makes it hard achieve high‐rate performance, therefore impairing power density. In this work, fiber‐in‐tube Co 9 S 8 ‐carbon(C)/Co designed with fast sodiation kinetics. experimental simulation analysis show that dominating capacitance mechanism for Na‐ion storage performance due abundant grain boundaries, three exposed layer interfaces,...
Among kinds of flexible tactile sensors, piezoelectric sensor has the advantage fast response for dynamic force detection. However, it suffers from low sensitivity at high-frequency stimuli. Here, inspired by finger structure-rigid skeleton embedded in muscle, we report a using rigid-soft hybrid force-transmission-layer combination with soft bottom substrate, which not only greatly enhances transmission, but also triggers significantly magnified effect d31 working mode sensory layer, instead...
Flexible pressure sensors are indispensable components in various applications such as intelligent robots and wearable devices, whereas developing flexible with both high sensitivity wide linear range remains a great challenge. Here, we present an elegant strategy to address this challenge by taking advantage of pyramidal carbon foam array the sensing layer elastomer spacer stiffness regulator, realizing unprecedentedly 24.6 kPa-1 ultra-wide 1.4 MPa together. Such linearity is attributed...
Biological exoskeletons, in particular those with unusually robust and multifunctional properties, hold enormous potential for the development of improved load-bearing protective engineering materials.

We have...
Activated N-doped hollow-tunneled graphitic carbon nanofibers with a novel architecture are excellent anode materials for lithium ion batteries, displaying superhigh reversible specific capacity and remarkable volumetric outstanding rate capability good cycling stability.
Mechanical exfoliation from bulk layered crystal is widely used for preparing two-dimensional (2D) materials, which involves not only out-of-plane interlayer cleavage but also in-plane fracture. Through a statistical analysis on the exfoliated 2D flakes, we reveal behaviors of six representative including graphene, h-BN, 2H phase MoS2, 1T PtS2, FePS3, and black phosphorus. In addition to well-known cleavage, these materials show distinctive tendency fracture along certain crystallography...
Porous silicon nanosheets are fabricated and exhibit good capacity superb cyclability. Molecular dynamics simulation is performed to reveal the capacity-porosity correlation.
Traditional anti-impact armors and shields are normally made of stiff hard materials therefore deficient in flexibility. This greatly limits their applications protecting objects with complex geometries or significant deformability. Flexible can be developed the application platelets soft materials, but lower rigidity flexible renders them incapable providing sufficient resistance against impact attacks. To address inherent conflict between flexibility traditional armors, here, a composite...

Biofouling refers to the unfavourable attachment and accumulation of marine sessile organisms (e.g. barnacles, mussels tubeworms) on solid surfaces immerged in ocean. The enormous economic loss caused by biofouling combination with severe environmental impacts induced current antifouling approaches entails development novel strategies least impact.

Tin holds promise as an anode material for lithium‐ion batteries (LIBs) because of its high theoretical capacity, but cycle life is limited by structural degradation. Herein, a novel approach exploited to insert Sn nanoparticles into the pores highly stable titanium dioxide–carbon (TiO 2− x –C) nanofiber substrates that can effectively localize postformed smaller nanoparticles, thereby address problem degradation, and thus achieve improved performance.
