Photothermal-manipulatable shape memory polyacrylamide/gelatin Janus hydrogel with drug carrier array for invasive wound closure and responsive drug release.

Traditional wound closure methods often present several issues, including additional puncture wounds, adverse effects from anesthesia, and noticeable scarring. Inspired by embryonic wound healing, a Janus hydrogel (PG/Au-Asp@PCM) is designed to manipulate non-invasive wound closure by photothermal-responsive self-contraction of PG/Au-Asp@PCM, which is attributed to the shape memory behavior of PG/Au-Asp@PCM under near-infrared (NIR). Wherein, gelatin acts as a thermally reversible "switch" and polyacrylamide creates stable and cross-linked "net-points".

Injectable bioresponsive bone adhesive hydrogels inhibit NLRP3 inflammasome on demand to accelerate diabetic fracture healing.

Diabetes is associated with excessive inflammation, which negatively impacts the fracture healing process and delays bone repair. Previously, growing evidence indicated that activation of the nod-like receptor (NLR) family, such as nod-like receptor thermal protein domain-associated protein 3 (NLRP3) inflammasome induces a vicious cycle of chronic low-grade inflammatory responses in diabetic fracture. Here, we describe the synthesis of a bone adhesive hydrogel that can be locally injected into the fracture site and releases a natural inhibitor of NLRP3 (rutin) in response to pathological cue reactive oxygen species activity (ROS).

Manipulating Interphase Chemistry for Aqueous Zn Stabilization: The Role of Supersaturation.

The limited cycling durability of Zn anode, attributed to the absence of a robust electrolyte-derived solid electrolyte interphase (SEI), remains the bottleneck for the practical deployment of aqueous zinc batteries. Herein, we highlight the role of local supersaturation in governing the fundamental crystallization chemistry of Zn4SO4(OH)6·xH2O (ZSH) and propose a subtle supersaturation-controlled morphology strategy to tailor the interphase chemistry of Zn anode. By judiciously creating local high-supersaturation environment with organic caprolactam to manipulate the precipitation manner of zinc sulfate hydroxide (ZSH), lattice-lattice matched heterogeneous nucleation of ZSH (001) and Zn (002) is realized in aqueous ZnSO4, producing a dense, pseudo-coincidence interface capable of functioning as decent SEI.

Super Tough Multifunctional MXene/PAA-CS Double Network Hydrogels with High Mechanical Sensing Properties and Excellent EMI Shielding Performance.

Hydrogels present significant potential in flexible materials designed for electromagnetic interference (EMI) shielding, attributed to their soft, stretchable mechanical properties and water-rich porous structures. Unfortunately, EMI shielding hydrogels commonly suffer from low mechanical properties, deficient fracture energy, and low strength, which limit the serviceability of these materials in complex mechanical environments. In this study, the double network strategy is successfully utilized along with the Hofmeister effect to create MXene/PAA (polyacrylic acid)-CS (chitosan) hydrogels and further strengthen and toughen the gel with (NH)SO solution.

Diacetylene-bridged covalent organic framework as crystalline graphdiyne analogue for photocatalytic hydrogen evolution.

Graphdiyne (GDY) alone as a photocatalyst is unsatisfactory because of its low crystallinity, limited regulation of the band gap, weak photogenerated charge separation, , and heterojunctioning with other materials is necessary to activate the photocatalytic activity of GDY. Through elaborate design, a diacetylene-rich linker (S2) was prepared and employed to construct a crystalline and structurally well-defined GDY-like covalent organic framework (COF, namely S2-TP COF) which merges the merits of both COF and GDY to boost the photocatalytic hydrogen evolution reaction (HER). By theoretical prediction on the donor-acceptor (D-A) pair, two other monoacetylene-bridged COFs (S1-TP COF and S3-TP COF) were prepared for comparison.
