Abstract ：
Lignin, a natural adhesive, provides sufficient mechanical properties for cell walls, inspiring its application in the field of wood adhesives. However, the majority of industrial lignin-derived adhesives necessitate the incorporation of copious quantities of crosslinking agents to guarantee their optimal mechanical properties. Nevertheless, this approach often gives rise to inherent limitations, including a deficiency in lignin content, environmental issues, and a complex reaction process that significantly impedes their green and large-scale applications. Here, a simple hot-pressing-assisted method was devised for the fabrication of a lignin-based adhesive (LGD). The LGD with an ultra-high lignin content of up to 86 wt% was synthesized from industrial alkali lignin by adding only a small amount of glycol diglycidyl ether (14%) and a simple hot-pressing process. The LGD exhibited an exceptional bonding effect, with an adhesive strength of up to 8.98 MPa (three-layer plywood) and a modulus of rupture of 64.6 MPa (seven-layer plywood). This work not only provides a green raw material and application strategy for the adhesive industry, but also paves the way towards the high-value utilization and large-scale applications of lignin polymeric materials. © 2025, The Authors.

Abstract ：
Cellulosic paper is an appealing substrate for flexible electronics, yet its modest strength, limited heat tolerance, and intrinsic hydrophilicity constrain performance. We report a polyimide (PI) sizing that permeates the fiber network to create an interpenetrating PI–cellulose framework. The treated paper reaches a tensile strength of 47.1 MPa, reported as an ~700% gain over the control. It also shows strong chemical tolerance, with 77% cellulose recovery and facile reshaping. This practical sizing route recasts paper as a strong, heat-resistant, and recyclable platform for flexible electronics. © 2025, The Authors. All rights reserved.

Abstract ：
This study experimentally investigates the integration of Fe-Co-Al @ BTC Metal-Organic Framework (MOF) into a double slope solar still (DSSS) to enhance the evaporation rate. Three configurations were tested: MOF as a nanofluid in the basin water (Case I), MOF as a nanofluid with an atomizer (Case II), and MOF for thin film evaporation (Case III). A comprehensive 4E analysis-Energy, Exergy, Economic, and Environmental-evaluated the performance of the DSSS relative to conventional solar still (CSS). The MOF improved DSSS performance through its superior thermal properties and large surface area. Performance results showed notable improvements. Energy efficiency increased significantly, with Case III improving by 103 %, Case II by 82.3 %, and Case I by 53.3 %. Exergy efficiency witnessed more dramatic enhancements, with Case III rising by 162 %, Case II by 137 %, and Case I by 70.6 %. Accumulated distillate followed a similar pattern, with Case III rising by 92.12 %, Case II by 68.54 %, and Case I by 34.66 %. Case III demonstrated the most promising outcomes, achieving the lowest freshwater cost at 0.0122 $/L-a 26.22 % reduction from CSS. Additionally, the MOF integration resulted in CO2 mitigation ranging from 1.49 to 2.2 tons annually, generating carbon credits between 37.13 and 54.94 $/year.

Abstract ：
In an era of frequent fire accidents and overburdened passive fire-safety systems, this study proposes an innovative solution strategy for active warning through the development of multifunctional fire-resistant composites. This strategy facilitates the transformation of active fire resistance technology through the synergistic integration of the design of advanced materials and intelligent systems. A three-dimensional hierarchical structure (PMG) combining mechanical robustness with multifunctional capabilities is produced through layer-by-layer self-assembly of graphene oxide with microcrystalline cellulose and polyvinyl alcohol. PMG12.5 has excellent tensile and compressive strength. The chemical synergy between phosphorus and nitrogen, combined with the physical barrier effect of graphene oxid, provides a dual flame retardant mechanism. Notably, the thermal reduction of graphene oxid triggers the formation of an in-situ conductive network for ultra-fast fire detection ( © 2025, The Authors. All rights reserved.

Abstract ：
Solar interface evaporators for desalination have gained a growing research interest due to its potential for sustainable water production. However, an efficient balance in performance for heat management, water transport, and salt tolerance and rejection is rather difficult to achieve in actual applications. Inspired by the vascular bundles arranged in order in parenchyma cells of seagrass, this study reports the vertical arrangement of 3D aerogel formed by the hybridization of sodium alginate and reduced graphene oxide (denoted as SrGAE) to demonstrate a highly efficient solar interfacial evaporation for desalination. Due to the biomimetic 3D architecture with vertically arranged channels, SrGAE successfully achieves a shortened distance for water transmission and expanded channel for salt discharge in comparison to a traditional evaporator. Furthermore, SrGAE can absorb external energy through evaporative cooling and reduce the water-evaporation enthalpy, achieving an excellent solar-steam conversion efficiency. Such properties of SrGAE enable a continuous evaporation of 20 wt% brine for 8 h under one sun illumination, thus achieving an evaporation rate of 3.7 kg.m(-2.)h(-1) and an outstanding solar-vapor conversion efficiency of 106 %.

Abstract ：
The research on bio-sourced adhesives has emerged as an essential topic for advancing the wood industry. Starch, typically used as a filler to modify synthetic resins, often requires complex pre-treatment when employed as a starting material for bio-sourced adhesives. In this work, a fully bio-sourced starch-phytic acid wood adhesive with superior water resistance and ultra-high flame-retardant properties was developed using the concept of "depolymerization and reconstruction" through a straightforward one-pot strategy. The co-reaction between corn starch (CS) and phytic acid (PA) established an effective cross-linking network within the adhesive, ensuring robust adhesion to the wood substrate and delivering excellent bonding performance and water resistance. The wet shear strength of plywood bonded with the CS-P0.75 adhesive reached 1.09 MPa, surpassing the requirement of China National Standard (GB/T 9846-2015, >= 0.7 MPa). The particleboard bonded using CS-P0.75 adhesive achieved an internal bond (IB) strength and modulus of rupture (MOR) of 1.09 MPa and 11.89 MPa, respectively, meeting the requirements of the China National Standard GB/T 4897-2015 for P3 type particleboard. Moreover, the CS-P adhesive demonstrated exceptional flame-retardant performance, with a limiting oxygen index (LOI) value of approximately 70 %. This study offers a convenient and sustainable approach to developing a promising starch-based wood adhesive with a reliable combination of properties, presenting a viable alternative to conventional synthetic resins (urea-formaldehyde, melamine-urea-formaldehyde, and phenolic resins).

Abstract ：
This paper presents a pyramid solar still with modifications to enhance energy, exergy, economic, and environmental performance, comparing a conventional distiller to a modified version with advanced features for improved efficiency. The system incorporates several innovative features to enhance performance. First, it includes a pyramid-shaped distillation unit integrated with evacuated tube technology with 200 L capacity storage, utilizing thin-film evaporation through a black jute structure for improved heat transfer. Second, four flat reflectors are strategically positioned around the pyramid distiller, aligning with the water heater to focus additional solar energy onto the system, further boosting the thin-film evaporation process. Lastly, a water cover cooling system, operating at a rate of 4 L per hour, was incorporated to regulate the increased evaporation rate resulting from these enhancements. The three modified distillers attained a daily yield of 5.78, 7.31, and 9.36 L/ m2 while the reference distiller did not exceed 3.32 L/m2. In other words, the modified distillers achieved productivity improvement ratios of 83.49, 120.18, and 193.42 %. The last case (best case) achieved daily exergy and energy efficiencies of 5.16 and 48.82 %, respectively, which was higher than those of the reference distiller by 125.60 and 43.42 %, respectively. Considering the heat transfer coefficients, the last case exhibited a daily average value of 59.89 W/m2 & sdot;K which was 146.36 % higher than the reference distiller. From an economic and environmental perspective, the last case reduced the cost of water to 0.0124 $/L along with carbon dioxide mitigation of 5.64 tons CO2.

Abstract ：
Shape memory polyimide (SMPI) has excellent thermal stability and chemical inertness, and was used in high-end applications, such as aerospace, microelectronics, etc. However, the unsatisfied strength and toughness is currently the key challenges of SMPI. Herein, lignin, a natural polymer, with abundant rigid benzene ring structures and reactive functional groups is used to enhance SMPI's mechanical properties and shape memory performance. The formation of hydrogen bonds and pi-pi interactions between lignin and SMPI matrix resulted in the simultaneously enhancement of strength and toughness through in-situ polymerization. As a result, the tensile strength and strain of composite films is increased from 73.45 MPa and 5.2 % to 114.5 MPa and 90.2 % at lignin content of 4 wt%, which are remarkably increased by 156 % and 1734 %, respectively. The shape recovery triggering temperature decreases similar to 7 degrees C with the increase of lignin content. What's more, the shape fixation rate (R-f: 99.8 %) and recovery rate (R-r: 100 %) of L/SMPI composite films was also improved, and various complex shapes can be molded. The good thermal stability was well maintained, in which the decomposition temperature (T-d) is similar to 507 degrees C and the glass transition temperature (T-g) is similar to 181 degrees C. The excellent performance of lignin-modified shape memory polyimide (L/SMPI) opened a new ear for high value application of natural polymer, particularly in shape memory material.

Abstract ：
This study explored the potential of two thermal energy storage materials - sand before demineralization (SBMR) and minerals after sand removal (MASR) - to boost the daily output of a hemispherical solar still (HSS). Both materials were prepared and characterized before being integrated into the HSS system for sensible heat storage. Additionally, the study focused on evaluating the effect of varying material depths, spanning from 0.25 cm to 2 cm, to identify the optimal depth for maximizing the HSS's performance. Two experimental setups were conducted: with and without an external condenser. A thermoenviroeconomic analysis was carried out to compare the performance of the modified HSS (MHSS) with SBMR, and MHSS with MASR to the conventional HSS (CHSS), both with and without the external condenser. Our findings demonstrate that a material depth of 0.75 cm optimizes productivity for MHSS configurations. Furthermore, incorporating an external condenser significantly enhances both thermal performance and productivity. Energy efficiency considerably increased, MHSS with SBMR showing a 57.13 % improvement and MHSS with MASR exhibiting an 88.35 % improvement over CHSS. Exergy efficiency also saw substantial gains, with the most significant improvement (85.26 %) observed in MHSS with MASR utilizing an external condenser. Daily yield was highest for MHSS with MASR, reaching 6.08 kg/m2 (an 88.24 % increase), followed by MHSS with SBMR at 5.06 kg/m2 (a 56.66 % increase). Regarding production costs, MASR-equipped MHSS without an external condenser achieved the most significant cost reduction (36.47 %) compared to CHSS.
