Smart multifunctional textiles are strongly demanded for their advantages of ensuring comfort, safety, and durability for human security protection, but they remain greatly challenged in the structure design and performance improvement. Herein, a novel Coolmax/cotton woven fabric with dual-faced structures (DFS) is fabricated, then spray coated with polydimethylsiloxane composite, and its comprehensive characterizations are fully evaluated. Janus configuration facilitates rapid directional water transport from the hydrophobic inner layer to the hydrophilic outer layer within 4.6 ± 0.45 s, thereby substantially enhancing thermal-moisture comfort under conditions of intense physical exertion and elevated temperatures. Flame retardancy is also imparted through a facile single-layer dip-coating strategy employing chitosan (CS)/phytic acid (PA)/ TiO 2 . Notably, introducing only 0.5 wt.% TiO 2 led to a significant increase in char residue, reaching at 7.61%. Sample CS-PA@TiO 2 (titanium dioxide) showed self-extinguishing behavior in the vertical burning test, as well as a significantly enhanced limiting oxygen index (LOI) to 35.3 ± 1.93 from 19.03 ± 1.25 for pure DFS fabric, and those of peak heat release rate and total heat release for sample CS-PA@TiO 2 is drastically declined by 65% and 47%, respectively. Moreover, the fabric maintained adequate mechanical strength and abrasion resistance, indicating excellent durability under repeated wear. This work will provide synergistically integrated multifunctional textiles through a simple, scalable approach.

In view of the fact that improper and excessive use of pesticides has posed severe threats to food quality, human health, ecological security, and aquatic ecosystems. A novel electrochemical sensing platform was fabricated with nitrogen, phosphorous, and boron ternary-doped reduced graphene oxide-supported cross-linked γ-CD-metal organic framework (NPB-rGO/CL-γ-CD-MOF) nanocomposites for the sensitive detection of carbendazim (CBZ). Choosing ethylenediamine, phytic acid, and boric acid as the N, P, and B source, the pre-synthesized NPB-rGO acted as the conductive substrate to further support CL-γ-CD-MOF from cross-linking γ-CD-MOF with diphenyl carbonate. The formed NPB-rGO/CL-γ-CD-MOF nanocomposites could accommodate numerous γ-CD molecules in CL-γ-CD-MOF for the specific capture of more CBZ via the host-guest interaction and activate the charge groups and spin densities of adjacent carbon atoms in NPB-rGO for the accelerative diffusion of CBZ towards the electrode surface. Such synergistic effect endowed the high sensitivity and selectivity for monitoring CBZ with the wide concentration range of 0.5–135 μM and low detection limit of 0.12 μΜ. Moreover, the designed electrochemical sensor was smoothly applied to detect CBZ in practical analyses with satisfactory results, which demonstrates that NPB-rGO/CL-γ-CD-MOF nanocomposites possess the bright prospect to become ideal electrode candidates in pesticide residue assays.

In view of the problem that epoxy resin cannot achieve effective flame retardancy, smoke and toxic gas suppression functions in fire, and poor interface compatibility with flame retardants, a coreshell structure with SiO 2 as the nucleus was designed, and a new multi-component flame retardant was prepared by introducing Ni and phytic acid using metalorganic frameworks (MOFs) as precursors. After mixing and curing with epoxy resin, the SiO 2 /CoNi-DH-PA/EP was obtained. With only 5% SiO 2 /CoNi-DH-PA added, the peak heat release, total smoke production, and total CO production of epoxy resin composites are reduced by 63.72%, 31.88%, and 63.74%, respectively, and the residue yield increased from 15.05% to 24.40%. It has been verified that SiO 2 , Co-Ni bimetallic ions and phytic acid have synergistic effects, which can induce and catalyze the formation of a complete and dense carbon layer. This significantly reduces the heat release, smoke, and toxic gas production, thereby reducing the fire hazard of epoxy resin. Additionally, the SiO 2 /CoNi-DH-PA/EP ensures good mechanical properties.

As a bio-based wood product, plywood is widely used in furniture, flooring, packaging, architectural decoration, etc. However, the flammability of plywood limits its application. Using flame-retardant adhesives to prepare plywood is the simplest way to improve its flame-retardant properties. However, a challenge in flame-retardant adhesives arose from the negative effect of flame retardants on the curing and bonding properties of adhesives. Herein, we developed a method to prepare a flame-retardant adhesive modified by using Z-3A molecular sieves as carriers to load flame retardants such as phytic acid and ammonium polyphosphate. The flame-retardant performance of obtained plywood bonded by this flame-retardant adhesive was significantly improved with robust bonding strength under extraordinarily low loading of flame retardants. Even if the loading rate of ZPA flame retardant for 2-ZPA-5 plywood was as low as 2.2 %, the total smoke production and the maximal peak value of the heat release rate were reduced by 79 % and 14 %, respectively, with the limiting oxygen index being 33.6 %, the time to ignition delaying by 14 s, robust wet bonding strength being 1.79 MPa, anti-loss rate as 1.06 ± 0.18 %, and moisture absorption rate as 4.45 ± 0.14 %. The whole process needs neither tedious work or equipment nor high loading of flame retardants. This judicious design strategy offers a versatile and scalable approach to preparing flame retardant plywood.

Recent research has focused on developing environmentally friendly flame-retardant coatings to improve the fire resistance of wood. In this study, phytic acid–guanazole (PG), a dual-functional compound synthesized through an ionic reaction between phytic acid and guanazole, was added to KH550-modified urea–formaldehyde resin (KUF) as both a curing agent and flame retardant. The−PO43−groups from phytic acid act as an acid source to accelerate char formation during combustion, while the −NH2groups introduced by guanazole release non-combustible gases to dilute oxygen in the air, synergistically enhancing flame retardancy. Additionally, the hygroscopic−PO43−groups absorb free water in the resin, reducing the curing temperature and accelerating coating solidification. The KH550 coupling agent improves compatibility between KUF and PG while introducing silicon, which forms SiO2during combustion to strengthen the char layer and further enhance flame resistance. Evaluations showed that PG outperforms conventional tannic acid (TA) in curing efficiency and fire resistance. Comprehensive analyses, including Differential Scanning Calorimetry (DSC), Limiting Oxygen Index (LOI), vertical flame tests, and cone calorimetry, confirmed PG’s dual functionality. Scanning Electron Microscope (SEM) and Raman spectroscopy revealed that PG-modified coatings form denser post-combustion char layers, directly linked to improved fire resistance. As a multifunctional additive, PG eliminates the need for separate curing agents and utilizes bio-based phytic acid, offering cost-effective and sustainable advantages for industrial applications.

The development of biomass-derived aerogel fibers for thermal insulation via wet spinning requires precise structural control to optimize performance. This study aims to regulate the molecular assembly of cellulose nanounits to engineer regenerated cellulose aerogel fibers (RCAFs) with enhanced insulating properties while reducing energy consumption. By leveraging acid-coagulation baths with varying H + concentrations during wet spinning, we manipulated cellulose chain aggregation to tailor pore size distribution within RCAFs. The resulting fibers achieved ultra-low thermal conductivity (0.0242 W m −1 K −1 ) through pore structure optimization and suppression of heat transfer pathways. This work establishes a scalable strategy for structurally tuning biomass-based aerogel fibers, demonstrating their potential for energy-efficient textiles. Future research should focus on scaling production and expanding applications in multifunctional, sustainable materials.

Developing highly active and robust bifunctional electrocatalysts for overall water splitting is of great significance for the production of green hydrogen energy. Herein, heterostructured CoP/NiCoP nanoparticles that are encapsulated one-to-one in nano caves of soda-biscuit-like ultrathin carbon nanosheets (CoP/NiCoP/CMS) are prepared, using melamine-formaldehyde sponge (MS) that grew Co/NiCo hydroxides as precursor and phytic acid (PA) as phosphorus source. Especially, the PA-induced blowing behavior during pyrolysis not only transforms the 3D networks of MS into 2D ultrathin carbon nanosheets of CMS, but also achieves the uniform one-to-one superconfinement of hetero-nanoparticles within both the intralayer nanocaves and interlayer spaces of the carbon nanosheets. Benefit from the superconfinement and interface engineering, CoP/NiCoP/CMS shows low overpotentials of 247 and 124 mV at 10 mA cm −2 , as well as good stabilities toward both oxygen and hydrogen evolution reactions, respectively. Moreover, CoP/NiCoP/CMS//CoP/NiCoP/CMS electrolyzer only requires 1.56 V to achieve 10 mA cm −2 . Experimental and theoretical results demonstrate that heterojunction interfaces can well regulate the electronic structure and enhance the intrinsic activity of CoP/NiCoP/CMS, meanwhile, soda-biscuit-like architecture guarantees the compatibility of high activity and good stability. This work proposes a novel and universal strategy for designing advanced electrocatalysts for efficient overall water splitting.

Moisture-electric generators (MEGs) are an emerging clean and accessible next generation of green power generation equipment. However, most hygroscopic materials used for MEGs still face challenges of low moisture absorption capacity and lack of anti-bacterial properties, resulting in low output voltage and poor long-term stability. In this work, a liquid-free antibacterial ionic conductive elastomer-based MEG was designed using L-carnitine/glycerol deep eutectic solvent with outstanding mechanical properties and great self-healing ability. Benefiting from the superb hygroscopic ability and ion transport capability, the assembled MEGs can spontaneously generate electricity over a wide relative humidity (RH) range from 30 % to 90 %, which can continuously output 0.83 V of voltage and 57.82 µA of current under 90 % RH for 6 h without obvious electrical performance degradation. Moreover, the MEGs can be directly used for breath monitoring and touch sensing. In addition, the ionic conductive elastomers exhibit long-term antibacterial ability, which ensures that the MEGs work stably for a long time. This work provides a feasible and efficient strategy to construct a green and high-performance energy source for sustainable and long-term applications.

Sustainable hydrogel-based supercapacitors are emerging as promising options for safe and green energy storage solutions, but suffer from low energy density and non-recyclability. Herein, a G-quadruplex-driven hydrogel electrolyte with recyclability and ion channels is successfully designed and applied to construct interface-compatible sustainable supercapacitors. The G-quadruplex-driven supramolecular network with ion channels not only enables hydrogel electrolytes to achieve high ionic conductivity, but also imparts thermally activated reversible regulation of network structure for the construction of interface-compatible supercapacitors. The G-quadruplex-driven hydrogel supercapacitors possess a high specific capacitance of 207.1 mF cm −2 and an energy density of 156.5 μW cm −2 at 0.386 mW cm −2 . More importantly, the G-quadruplex-driven hydrogel electrolyte demonstrates excellent recyclability. The reconstructed hydrogel electrolytes and supercapacitors maintain comprehensive properties similar to those of the original materials. This strategy for the G-quadruplex-driven recyclable hydrogel electrolyte offers valuable insights into sustainable energy materials and energy storage devices.

Thermal energy storage wood (TESW) is a passive energy-efficient building material that effectively regulates indoor temperature and homogenizes the heat distribution. However, the energy storage performance of TESW is diminished by leakage. In addition, the flammable phase change materials incorporated within the wood are potential fire hazards. In this study, TESW with flame-retardant and anti-leakage (P 9 A 1 –UP–wood C ) was prepared by impregnating wood cell lumen with polyethylene glycol (PEG), phytic acid, urea and acrylic acid, and thermally initiating cross-linking. Accordingly, the enthalpy and phase change temperature of P 9 A 1 –UP–wood C were 47.98 J g −1 and 25.07 °C, respectively. Meanwhile, 98.95 % of the enthalpy remained after 100 cycles. In addition, the total smoke release of P 9 A 1 –UP–wood C was reduced by 28.61 % from that of raw wood (wood C ), and the production rates of CO 2 and CO during the combustion process were also significantly decreased, indicating good smoke-suppressing and toxicity-reducing effects of the flame retardants. The building-energy efficiency of the TESW was simulated in Designbuilder software. This flame-retardant, leakage-resistant TESW prepared via a toxic solvent-free method can improve the safety and long-term stability of passive energy-saving materials and promotes the storage and reuse of low-grade thermal energy.

The development of cost-effective and high-efficiency catalysts for hydrogen generation through ammonia borane (AB) hydrolysis remains a significant challenge in the field of clean energy production. Controlled introduction of dopants into catalysts offers a promising strategy to enhance the intrinsic activity of noble metals, such as ruthenium (Ru), by tuning their electronic energy levels. Herein, we explored the interactions between cobalt oxide and Ru nanoparticles (NPs) supported on N and P co-doped carbon-based nanostructures. Notably, the N, P co-doping uniquely modulates the electronic structures, simultaneously tuning the electronic properties of carbon support and cobalt oxide. Therefore, this composite catalyst demonstrates the distinctly enhanced metal–support interactions, achieving a 3.5-fold increase in turnover frequency (TOF) to 1429 molH2·molRu–1·min–1 at 25 °C, compared to the undoped counterparts. Moreover, the catalyst retains over 90% of its initial activity after five cycles of reuse. Experimental and theoretical analyses attribute the superior catalytic activity of Ru@CoOx/NPC to the optimized electronic configuration of CoOx and the downward shift in its d-band center induced by N and P doping. This microstructural alteration further modifies the electronic state of Ru, enhancing H2O adsorption and dissociation. These findings offer a pragmatic tactic for electronic structure modulation to design highly active and selective noble-metal-based catalysts for AB hydrolysis.

Porous carbon coated manganese compounds nanoparticles (MnX, X = P, O or S) is a kind of potential catalysts for oxygen electrocatalysis due to the controllable d-band center, while the complex mechanism and performance difference is yet to reveal due to the lack of catalyst platform. Herein, the ORR catalytic activity and difference reason between manganese phosphide, oxide, and sulfide are tested and discussed via manganese compounds contained carbon-based catalyst platforms synthesis and Density functional theory (DFT). Manganese compounds nanoparticles active sites are uniformly distributed in porous carbon fibers/graphene composite, which guarantees the high mass transfer ability and conductive ability. Experiment results show that catalyst with Mn 2 P active sites exhibits best bifunctional catalytic activity for ORR/OER, which only need 0.89 V (vs. RHE) to achieve a half-wave potential (E 1/2 ) in ORR and 1.58 V (vs. RHE) to reach the overpotential at 10 mA cm −2 (E 10 ) in OER. Theoretical analysis shows that the d-band center of Mn in Mn 2 P is much closer to the Fermi level than MnS and MnO. The rate-determining process of Mn 2 P has the smallest energy barrier of 0.56 eV, indicating the best ORR activity. This work provides paves a solid way for the synthesis of carbon-based catalysts with manganese compounds active sites.
