Abstract
Silicon (Si), a high-capacity electrode material, is crucial for achieving high-energy-density lithium-ion batteries. However, Si suffers from poor cycling stability due to its significant volume changes during operation. In this work, a tannic acid functionalized aqueous dual-network binder with an intramolecular tannic acid functionalized network has been synthesized, which is composed of covalent-cross-linked polyamide and ionic-cross-linked alginate (Alg(Ni)-PAM-TA), and employed as an advanced binder for stabilizing Si anodes. The resultant Alg(Ni)-PAM-TA binder, incorporating diverse functional groups including amide, carboxylic acid, and dynamic hydrogen bonds, can easily interact with both Si nanoparticles and the Cu foil, thereby facilitating the formation of a highly resilient network characterized by exceptional adhesion strength. Moreover, molecular dynamics (MD) simulations indicate that the Alg(Ni)-PAM-TA network shows an increased intramolecular hydrogen bond number with increasing concentration of TA and a decreased intramolecular hydrogen bond between PAM and Alg as a result of the aggregation behavior of tannic acids themselves. Consequently, the binder significantly enhances the Si electrode's integrity throughout repeated charge/discharge cycles. At a current density of 0.84 A g-1, the Si electrode retains a capacity of 1863.4 mAh g-1 after 200 cycles. This aqueous binder functionalized with the intramolecular network via the incorporation of TA molecules holds great promise for the development of high-energy-density lithium-ion batteries.

Abstract
As a low-grade sustainable heat source, the breath waste heat exhaled by human bodies is always ignored, although producing a greater temperature than ambient. Converting this heat into electric energy for use as power sources or detecting signals is extremely important in cutting-edge wearable medicine. This heat-to-electricity conversion is possible with thermogalvanic hydrogels. However, challenges remain in their antifreezing and antidrying properties, significantly restricting the durability of thermogalvanic gels in practical applications. Herein, a dual-network poly(vinyl alcohol)/gelatin (PVA/GEL) gel thermogalvanic device with Fe(CN)63-/4- as a redox pair is developed, with an outstanding low-temperature durability and antidrying capacity. These features result from the use of a binary H2O/GL (glycerin) solvent to limit hydrogen bonding between water molecules. The prepared thermogalvanic gel patch is capable of easily converting physiological data into understandable electrical impulses using the temperature difference between the ambient environment and the heat produced by human breathing, realizing a simple self-powered respiratory monitoring strategy for the first time. Even below zero temperature, the gel patch-based mask can operate normally, implying it fits into low-temperature environments. This study sheds fresh light on the development of active wearable medical electronics that are powered by demic low-level heat.

Abstract
The field of living materials seeks to harness living cells as microfactories that can construct a material itself or enhance the performance of material in some manner. While recent advances in 3D printing allow microbe manipulation to create bespoke living materials, the effective coupling of these living components in reinforced bioink designs remains a major challenge due to the difficulty in building a robust and cell-friendly microenvironment. Here, a type of dual-network bioink is reported for the 3D printing of living materials with enhanced biocatalysis capabilities, where bioinks are readily printable and provide a biocompatible environment along with desirable mechanical performance. It is demonstrated that integrating microbes into these bioinks enables the direct printing of catalytically living materials with high cell viability and maintains metabolic activity, which those living materials can be preserved and reused. Further, a bacteria-algae coculture system is fabricated for the bioremediation of chemicals, giving rise to its potential field applications.

Abstract
Novel sunscreen products based on bioadhesive/gel systems that can prevent the skin penetration behaviors of UV filters have attracted increasing attention in recent years. However, integration is very difficult to achieve and control on the wet surface of the skin under sweaty/dynamic physiological conditions, resulting in functional failure. Herein, we demonstrated the fabrication of a novel dual-network hydrogel sunscreen (DNHS) based on poly-γ-glutamic acid (γ-PGA) and tannic acid (TA), which demonstrated prominent UV protection properties across broad UVA and UVB regions (360-275 nm). Due to a three-dimensional network microstructure and a highly hydrated nature that mimics the extracellular matrix of natural skin, DNHS can perfectly match the skin surface without irritation and sensitization. In addition, the intermolecular hydrogen bond interactions of γ-PGA and TA provide an important driving force for coacervation, which endows the DNHS with remarkable self-recovery properties (within 60 s). Moreover, due to the multiple interfacial interactions between γ-PGA/TA and the protein-rich skin tissue surfaces, DNHS simultaneously possesses excellent skin-integration and water-resistance capacities, and it can be readily removed on demand. Our results highlight the potential of the DNHS to be used in next-generation sunscreens by providing long-term and stable UV protection functions even under sweaty/dynamic physiological conditions.
