Wound repair is a common clinical challenge and is critical to patients’ life quality after skin injuries. Despite extensive efforts, the wound healing remains unsatisfied due to the complicated cell behavior and biochemistry of the wound healing process. In recent years, biomaterials have gained attention for their potential to promote skin regeneration, underscoring the need for innovative materials

Electroluminescent devices, particularly in fiber form, demand highly transparent and conductive materials as external electrodes to maintain high brightness during stretching. As a result, materials with poor conductivity but good transparency, or good conductivity but poor transparency, are restricted in their applicability. Addressing this challenge, we introduce a compensation strategy for external

A key challenge in achieving a circular economy within the plastics industry lies in the upcycling and revalorization of post-consumer recycled (PCR) thermoplastic polyolefins (TPOs). PCR polyolefins typically exhibit inferior mechanical properties compared to virgin materials, limiting their use to low-value applications. Covalent adaptable networks (CANs), a class of dynamic crosslinked structures

Icephobic surfaces (e.g., superhydrophobic surfaces and slippery surfaces) have significant economic, energy and safety implications by offering prevention and easy removal of ice in many critical applications. So far, the durability of these surfaces remains to be a major concern, preventing their adoption in practice. Here, we design a low-surface-energy framework of bridging rigid nanoparticles

Achieving in vivo fast and long-lasting fluorescent tracking to short lived NO becomes challenging, which arises from probes needing efficient interaction, hindered by uncontrollable self-aggregation and a preference for hydrophobic conditions in NO-specific reactions. It is imperative to transform the uncontrollable aggregated structure to dispersed structure and umpolung of the nanoenvironment from

Two-dimensional MoS2 materials exhibit considerable promise for elemental mercury adsorption.

The degradation rate constant for the calcined S-doped

Rampant dendrite growth and hydrogen evolution reaction of Zn anode severely hinder the practical application of aqueous zinc-ion batteries (AZIBs). Traditional surface modifying layers tend to have distinct interface with the Zn plate, which readily results in detachment and failure of the modification under repeated cycling. Herein, inspired by mussel adhesive proteins, a uniform and dense polydopamine

The heterogeneous migration of dual ions within the gel polymer electrolytes (GPEs)-based lithium metal batteries leads to significant concentration polarization and compromises interfacial stability during cycling.

Aptamer-based biosensing methods, despite achieving advancements in the detection of tumor-associated proteins, are only effective for a limited number of specific proteins and thus have restricted clinical value. This is mainly attributed to the requirement of prior knowledge and precise modulation of the aptamer structure, or the special spatial distribution of multiple binding sites in the target
