“…Last, the biological reactions in the surrounding medium can create concentration gradients of small molecules that will interact with the chromatophore; multicomponent physiological reactions have been known to control chromatophore aggregation and dispersion (44). We also emphasize that diffusiophoresis of chromatophore-coated particles has been experimentally reported in literature (43). In a biological setting, we expect that particle motion is made complex by effects such as cell-cell adhesion and resistance of the porous membrane.…”

“…First, the size of a typical chromatophore can range from 1 to 30 μm, which is typically the range where colloidal particles are diffusiophoretic ( 41 , 42 ). Second, recent experimental results suggest that chromatophores are charged and interact with the surrounding medium ( 43 ). Last, the biological reactions in the surrounding medium can create concentration gradients of small molecules that will interact with the chromatophore; multicomponent physiological reactions have been known to control chromatophore aggregation and dispersion ( 44 ).…”

Turing patterns are fundamental in biophysics, emerging from short-range activation and long-range inhibition processes. However, their paradigm is based on diffusive transport processes that yield patterns with shallower gradients than those observed in nature. A complete physical description of this discrepancy remains unknown. We propose a solution to this phenomenon by investigating the role of diffusiophoresis, which is the propulsion of colloids by a chemical gradient, in Turing patterns. Diffusiophoresis enables robust patterning of colloidal particles with substantially finer length scales than the accompanying chemical Turing patterns. A scaling analysis and a comparison to recent experiments indicate that chromatophores, ubiquitous in biological pattern formation, are likely diffusiophoretic and the colloidal Péclet number controls the pattern enhancement. This discovery suggests that important features of biological pattern formation can be explained with a universal mechanism that is quantified straightforwardly from the fundamental physics of colloids.

“…Janus particles, a surface partitioned material, were proposed by P.-G. de Gennes in his Noble Prize address to depict a special class of colloidal particles with distinct chemical components (e.g., inorganic and organic), physical properties (e.g., soft and hard), or functionality (e.g., hydrophilicity and hydrophobicity) on their two hemispheres. [39,40] The opposite composition or properties on the surface of one object make it show attractive attention in the solid emulsifier, [41,42] functional coating, [43][44][45] compatibilizer for polymer blends, [46][47][48] colloidal motor, [49,50] etc. This Janus particle with bicomponent or biphasic property is expected to address the dilemma between mechanical properties and conductivity of composite, achieving the largely stretchable conductors by promoting the dynamic reconstruction of the conductive pathway.…”

There is a long‐standing conflict between the large stretchability and high sensitivity for strain sensors, a strategy of decoupling the mechanical/electrical module by constructing the hierarchical conductor has been developed in this study. The hierarchical conductor, consisting of a mechanically stretchable layer, a conductive network layer, and a strongly bonded interface, can be produced in a simple one‐step process with the aid of soft‐hard Janus nanoparticles (JNPs). The introduction of JNPs in the stretchable layer can evenly distribute stress and dissipate energy due to forming the rigid‐flexible homogeneous networks. Specifically, JNPs can drive graphene nanosheets (GNS) to fold or curl, creating the unique JNPs‐GNS building block that can further construct the conductive network. Due to its excellent deformability to hinder crack propagation, the flexible conductive network could be stretched continuously and the local conductive pathways could be reconstructed. Consequently, the hierarchical conductor could detect both subtle strain of 0−2% and large strain of up to 370%, with a gauge factor from 66.37 to 971.70, demonstrating outstanding stretchability and sensitivity. And it also owns large tensile strength (5.28 MPa) and high deformation stability. This hierarchical design will give graphene‐based sensors a major boost in emerging applications.This article is protected by copyright. All rights reserved

combinations of metal clusters and organic linkers endow MOFs with controllable physical and chemical properties. [4][5][6][7] Over the last two decades, thousands of MOFs have been prepared and widely applied in many different fields, such as catalysis, [8,9] drug delivery, [10,11] gas separation and storage, [12][13][14][15] and biomedical imaging [16,17] due to these unique properties. Interestingly, MOFs can be purposefully functionalized with chemical groups through in situ synthesis or post-synthetic modification for some special applications without changing their structure. [18][19][20] Besides, much effort has been devoted to developing composite materials integrating MOFs crystals with polymer to further widen their application. [21,22] Triboelectric nanogenerator (TENG) as an eco-friendly energy-harvesting device can effectively convert ambient mechanical energy including wind, human activities, and water flow into electrical energy. [23][24][25][26][27] The nature of the triboelectric pair materials, especially triboelectric polarity, plays an essential role in the triboelectric behaviors of TENG. As far now, most of the triboelectric materials used to assemble the TENG come from the triboelectric series which consists of a few metal and limited polymer. [28] Polydimethylsiloxane (PDMS) is considered one of the broadest parent materials for TENG based on composite by virtue of its unique properties of transparency, high gain-electrons ability, flexibility, and easy fabrication. The surface morphology control with micro/nanostructures and surface functionalization with some appropriate functional groups can improve the output performance. [29][30][31] Zhang et al. reported a common technique to improve the energy density of TENG through a fluorocarbon plasma surface treatment. [29] Besides, adding the filler to the polymer has become a common strategy to optimize the triboelectric behaviors. [32] Most of the materials acting as fillers to fabricate composites are inorganic materials, such as graphene, [33] MXene, [34] and SrTiO 3 . [35] Recently, a few MOFs have been used in triboelectric nanogenerators (TENG) as active fillers. [36][37][38] Our groups reported humidity-resistant PDMS@HKUST-1 TENG and the performance of nanocomposite TENG is not decreased when the relative humidity is increased. [36] Chen et al. reported that planarly aligning 2D MOFs nanoflakes are more excellent for improving the triboelectric behaviors of triboelectric nanogenerators than Metal-organic frameworks (MOFs) are recently used in triboelectric nanogenerator (TENG) to enhance output performance. Although functional groups tremendously influence the output performance of TENG, the effect of functional groups for MOFs on the output performance is yet not systematically studied. In this paper, polydimethylsiloxane (PDMS) composite TENG is designed based on isostructural UiO-66-R (R = H, NH 2 , NO 2 , and Br) family filler, and the effect of filler with various functional groups on the output performance of the TENG is fir...
