Mussel-inspired conductive hydrogels are attractive for the development of next-generation self-adhesive, flexible skinlike sensors. However, despite extensive progress, there still some daunting challenges that hinder their applications, such as inferior optical transparency, low catechol content (e.g., poor adhesion), well limited sensation performances. Here, we report a dopamine-triggered gelation (DTG) strategy fabricating mussel-inspired, transparent, and hydrogels. The DTG design...
Daytime passive radiative cooling is a promising electricity-free pathway for terrestrial buildings. Current research interest in this strategy mainly lies tailoring the optical spectra of materials strong thermal emission and high solar reflection. However, environmental heat gain poses crucial challenge to building at subambient temperatures. Herein, we devise scalable insulating cooler (TIC) consisting hierarchically hollow microfibers as envelope that simultaneously achieves daytime...
Owing to its 100% theoretical salt rejection capability, membrane distillation (MD) has emerged as a promising seawater desalination approach address freshwater scarcity. Ideal MD requires high vapor permeate flux established by cross-membrane temperature gradient (∆T) and excellent durability. However, it's difficult maintain constant ∆T owing inherent heat loss at feedwater side resulting from continuous water-to-vapor transition prevent wetting transition-induced fouling scaling. Here, we...

ABSTRACT Carbon nanofiber sheets were developed through filtering well‐dispersed carbon (CNF) aqueous solution of CNF particles with 0.4 μm hydrophilic polycarbonate membrane by the aid high‐pressure air. They used to functionalize composites resin transfer molding method. Their functionalized characterized scanning electron microscopy (SEM), four‐point probes and a vector network analyzer measure their morphologies, electrical conductivity, electromagnetic interference (EMI) shielding...
Shaping soft and conductive materials into preferential architectures via 3D printing is highly attractive for numerous applications ranging from tactile devices to bioelectronics. A landmark type of hydrogels/ionogels. However, 3D-printed hydrogels/ionogels still suffer a fundamental bottleneck: limited stability in their electrical-mechanical properties caused by the evaporation leakage liquid within Although photocurable liquid-free ion-conducting elastomers can circumvent these...
Extensive work have been done to harvest untapped water energy in formats of raindrops, flows, waves, and others. However, attaining stable efficient electricity generation from these low-frequency kinetic energies at both individual device large-scale system level remains challenging, partially owing the difficulty designing a unit that possesses liquid charge transfer properties, also can be seamlessly integrated achieve preferential collective performances without introduction tortuous...
Abstract Cancer stem cells (CSCs) are a rare cell population in tumors that responsible for tumor recurrence and metastasis. They priority as therapeutic targets, however, assays targeting CSCs have been limited by expanding maintaining vitro. Here, the authors find gelatin methacryloyl (GelMA)‐nanoclay hybrid hydrogels can induce enrich colorectal assisted three‐dimensional (3D) bioprinting. The presence of nanoclay increases printability, Young's modulus, pore size, cytocompatibility...

Designing underwater adhesives with short bonding time yet strong adhesion is in pressing demand many applications such as construction and medical healthcare. However, shortening the normally leads to premature thus weak adhesion. Such trade-off becomes more pronounced presence of interfacial water, which disrupts adhesive–adherend interactions. The adverse influence water on can be alleviated by various dehydrating strategies; however, attaining high within a still remains challenge. Here,...
Pressure-sensitive adhesives (PSAs) are extensively used in diverse applications such as semiconductor manufacturing, labeling, and healthcare because of their quick viscoelasticity-driven physical adhesion to dry surfaces. However, most the existing PSAs normally fail maintain or even establish under harsh conditions, particularly underwater, due lack robust chemical functionalities for chemistry-based adhesion. Meanwhile, these incapable altering response external stimuli, limiting...
