Initial residual stress is omnipresent in biological tissues and soft matter, and can affect growth-induced pattern selection significantly. Here we demonstrate this effect experimentally by letting soft tubes grow in the presence or absence of initial residual stress and by observing different growth pattern evolutions. These experiments motivate us to model the mechanisms at play when a growing bilayer tubular organ spontaneously displays buckling patterns on its inner surface. We demonstrate that not only differential growth, geometry and elasticity, but also initial residual stress distribution, exert a notable influence on these pattern phenomena. Prescribing an initial residual stress distribution offers an alternative or a more effective way to implement pattern selection for growable bio-tissues or soft matter. The results also show promise for the design of 4D bio-mimic printing protocols or for controlling hydrogel actuators.

Soft-matter electrolytes have garnered significant attention due to their improved safety features, rendering them viable options for the creation of Li metal batteries with high energy densities. However, establishing effective interfacial contact between the electrodes and soft-matter electrolyte remains a significant challenge, necessitating modifications at the interface. In this study, we design an artificial composite electrolyte interphase (PEG-Cs SEI) on the surface of the Li metal anode to improve ion transport between the soft-matter electrolyte and Li metal. The PEG-Cs SEI layer exhibits high flexibility and mechanical strength, effectively mitigating the lithium dendrite growth and volume expansion. As a result, Li||Li cells assembled with PEG-Cs SEI-modified lithium metal anodes exhibit stable performance for more than 1700 h, maintaining small overpotential even at high current densities and capacities (2.45 mAh cm −2 ). With a LiNi 0.6 Co 0.2 Mn 0.2 O 2 (NCM622) cathode, the battery shows a capacity up to 182 mAh g −1 at first discharge with cut-off voltage of 4.5 V. Furthermore, in a pouch cell configuration, the battery achieves 100 % capacity retention over 90 cycles and successfully passes safety tests, without fire or smoke. Combining the modified lithium metal anode with soft-matter electrolytes paves a promising way for the effective implementation of high-energy-density Li metal cells.

The molecular ordering and defects in self-assembled soft matter systems are pivotal to their functionality and the advancement of innovative applications. However, achieving precise guidance in the assembly and dynamical modulation of defect structures in an artificial manner remains a formidable challenge in soft matter and interdisciplinary science. Herein, a digitally controlled pixelated holographic lithography system is established to fabricate nanoscale surface reliefs, enabling precise manipulation of smectic liquid crystal lamellar defect structures. These surface reliefs, with customizable topographic features, facilitate versatile smectic soft defect engineering, allowing selective assembly of square focal conic domains and oily streak defects, along with precise control over their periodicity, orientations, and patterned coexistence within micro-regions. The defect structures demonstrate exceptional stability and durability under UV irradiation, providing a robust framework for versatile defect engineering. This work opens a new pathway for manipulating lamellar superstructures in soft matter, offering potential applications in advanced functional materials and devices.

To deal with the demulsification of O/W emulsions, a novel kind of core–shell structural amphiphilic soft matter, HPEI-g-Cn (n = 10, 12, 14, 16, 18), with hyperbranched polyethyleneimine (HPEI) as the core and fatty acid chain Cn as the shell, is designed and synthesized. With the existence of amphiphilic HPEI-g-Cn, O/W emulsions can be thoroughly separated into two phases with a clear oil–water interface to reach demulsification equilibrium within 40 min. The oil removal ratio can exceed 99.9% under the addition of 40 ppm in simulative emulsions, and simultaneously the water content in the oil phase is less than 0.01%. This demulsifier can also contribute to excellent separation efficiency (up to 99.9%) for O/W emulsions from two China's oilfields, and even for heavy oil emulsions. More importantly, it is noted that the HPEI-g-Cn demulsifiers after demulsification are evenly and tightly dispersed at the oil–water interface as shown by wide-angle X-ray scattering (WAXS) and cryo-electron microscopy (cryo-EM), which is beneficial to the subsequent recovery and utilization. With eco-friendly characteristics, outstanding demulsification performance and promising recyclability, the amphiphilic macromolecules HPEI-g-Cn as special soft matter display great promise to achieve industrial applications in the future.

Exploring soft matter systems with high response sensitivity to magnetic fields has been a long-standing issue, which can realize contactless and non-destructive modulation of the materials’ properties. 2D material colloids have emerged as promising candidates, while current experiments suggest that their response sensitivity approaches a bottleneck. Here, a 2D material colloid is reported with anomalously large magnetic response sensitivity, in which 2D materials stack coplanarly and roll into scrolls, forming a unique assembly structure. The assembly of 2D materials generates a giant equivalent particulate magnetic susceptibility anisotropy and enhances the ordered orientation, which contributes to a record magneto-optical coefficient of 3.2 × 10 4 m −1 T −2 , being one order of magnitude larger than the previous largest value. Thanks to this, magnetic field viewers are fabricated with a detection limit of ≈25 mT and a spatial resolution in millimeter scale. This work not only provides insight in the responsivity modulation of soft matter systems by regulating interaction among constituent units but also unlocks their applications across various fields.

Interest in creating soft active matter that can repeatedly undergo shape morphing and self-sensing in response to external stimuli is growing. Magneto-active soft matter (MASM) with untethered, fast, and reversible shape reconfiguration is highly desirable for diverse applications in biomedical devices , wearable devices , soft robotics. In this work, we develop a heat-assisted magnetic reprogramming strategy for fabricating MASMs capable of reprogrammable shape-morphing and self-sensing functions. The magnetic reprogramming strategy is based on heating thermoplastic matrix above its melting point and reorienting soft-magnetic particle chains by applying magnetic fields during cooling. By reprogramming magnetization profiles through particle chain reconstruction of printed architecture, we demonstrate multiple deformation modes with distinct shape-morphing. This magnetic reprogramming approach enabled multiscale and reprogrammable soft machines with the tunable actuation response, such as adaptive grasping of a soft gripper. In addition, in combining with the unique sensing mechanism of triboelectric skin (tribo-skin), the self-sensing performance of MASMs is realized by using electrical signals to identify the deformation and contact behaviors. We anticipate that the magnetic reprogramming strategy and multimaterial 3D printing-assisted technique can open new avenues for the fabrication of multifunctional MASMs.

Conventional lipid extraction from fish by-products typically relies on high water input and disruption by thermal or hydrolysis to break emulsions and release oil. This study introduces a fundamentally reversed mechanism by micro-aqueous extraction (MAE). This method induces oil release via limited hydration and reassembly of the soft matter without heat or dilution. This MAE approach first dehydrates fish by-products until moisture content reaching ~18%, reassembly forming a protein–lipid matrix of high internal phase emulsion gel (φ ~75%). Upon controlled micro-aqueous hydration and low-shear agitation, structured proteins aggregate and destabilize oil droplets and release entrapped oil. Compared to heat extraction (HE), MAE achieved higher oil recovery (94.3% vs. 76.4%), shortened processing time by 35%, and decreased oil total oxidation value (TOTOX 1.33 vs. 2.88). Life cycle assessment confirmed lower environmental burden with 62% reduction in CO₂ emission. The fish meal obtained by MAE retained superior emulsifying activity and structural integrity. Mechanistically, micro-aqueous hydration reduced α-helix content of proteins and decreased oil droplet stability, thereby promoting demulsification. In contrast, drying at 60 °C resulted in lower turbidity and smaller aggregation size of myofibrillar proteins compared to drying at 30 °C, which enhanced their interfacial stabilization. Rheological analysis further revealed that water-limited restructuring of the myofibrillar network played a critical role in controlling viscoelasticity (as reflected by G', G'') and extraction efficiency. This work reveals a counterintuitive pathway for oil recovery, governed by moisture-regulated soft-matter reorganization, which presents a low-energy, high-yield, and sustainable approach for fish by-product valorisation.

Many biological organisms can tune their mechanical properties to adapt to environments in multistable modes, but the current synthetic materials, with bistable states, have a limited ability to alter mechanical stiffness. Here, we constructed programmable organohydrogels with multistable mechanical states by an on-demand modular assembly of noneutectic phase transition components inside microrganogel inclusions. The resultant multiphase organohydrogel exhibits precisely controllable thermo-induced stepwise switching (i.e., triple, quadruple, and quintuple switching) mechanics and a self-healing property. The organohydrogel was introduced into the design of soft-matter machines, yielding a soft gripper with adaptive grasping through stiffness matching with various objects under pneumatic-thermal hybrid actuation. Meanwhile, a programmable adhesion of octopus-inspired robotic tentacles on a wide range of surface morphologies was realized. These results demonstrated the applicability of these organohydrogels in lifelike soft robotics in unconstructed and human body environments.

Switchable surfactants are an emerging class of environmentally friendly compounds that can be reversibly triggered between active and inactive states in response to external stimuli, enabling on-demand or on-command control over the interfacial properties. In this work, a type of imidazoline-based CO2-switchable surfactants was synthesized and systematically investigated. Structural characterization was performed by using Fourier transform infrared and 1H NMR spectroscopy, confirming the successful formation of long-chain alkyl imidazolines. Their surface activity and critical micelle concentration (CMC) were evaluated by measuring surface tension and interfacial tension, revealing strong adsorption behavior and efficient micellization. Conductivity and NMR analyses demonstrated the reversible transition between neutral and ionic forms under alternating CO2/N2 bubbling, confirming the robustness and repeatability of the switching process. The emulsification/demulsification cycles were repeated over multiple switching operations, where oil/water emulsions were stabilized by their bicarbonate salt forms with long-term stability, whereas the neutral forms induced rapid demulsification. These findings not only establish the fundamental interfacial behavior of imidazoline-based surfactants but also highlight their potential applications in enhanced oil recovery, chemical separation, drug delivery, and sustainable process design.

This paper reports an interesting type of self-assembly systems based on dynamic covalent bonds. The systems are pH-responsible and reversible, which could be utilized for controlling the morphology transformation of the assemblies. In alkaline conditions, the amine group of 11-aminoundecanoic acid (AUA) can connect with the aldehyde group of benzaldehyde (BA) or 1-naphthaledhyde (NA) by dynamic covalent bond to form a small organic building block accompanied by the morphological transformation from vesicles to fibers. When pH is lowered to a neutral value, the dynamic covalent bonds (imine bonds) can be hydrolyzed, leading to the dissociation of fibers and appearance of spherical aggregates. The transformation was confirmed reversible as fibers appeared again when the pH was changed back to alkaline value. In addition, a reversibly controlled gel was designed based on the nanofiber formation. NaCl, which is capable of greatly enhance the nanofiber density and cross-linking, was used to induce the growth of free-standing gel from free-flowing nanofiber system, and the resultant gel was proven to be pH-reversible.

A new phenylboronic acid based gelator was developed to prepare low-molecular-weight organogel (LMOG), which could interact with several solvents to assemble into a three-dimensional nanofiber network. 1H NMR spectroscopy study suggests that the driving force for the gelation includes hydrogen bonding and π–π stacking. Evaluated by UV-spectroscopy, the gel showed a prompt initial response to glucose at low concentration of 0.012 mmol/mL, which is a critical concentration of venous plasma glucose for diabetes. Significantly, this organogel exhibits excellent sensitivity to glucose among seven sugars tested (i.e., mannitol, galactose, lactose, maltose, sucrose, and fructose). The proposed formation of hydrogen-bonded complexes during the glucose sensing was supported by our energy calculation. Meanwhile, this organogel exhibits pH-response. Importantly, this LMOG could be conveniently recycled and thus be reused.

Self-assembly of N -fluorenyl-9-methoxycarbonyl glutamic acid (Fmoc-Glu) in water generates metastable single-wall nanotubes. These nanotubes entangle and bundle together to form unstable gels that shrink with time and finally result in lamellar crystalline precipitates. Melamine (Mm) was employed as a supramolecular modifier and stabilizer to improve the stability of the nanotubes. Mm interacts with the carboxyl-rich surfaces of the nanotubes via H-bonds and static electronic forces to diminish the high affinity of individual nanotubes and facilitate Fmoc-Glu supergelation (critical gelation concentration <0.1 wt %). Although the basic process of nanotube formation is not disturbed, Mm inverts the supramolecular helicity of nanotubes from P to M .
