Abstract ：
As a natural polymer, cellulose has emerged as a promising candidate for constructing versatile materials and products due to its intrinsic biocompatibility, environmental degradability, and structural stability. As a state-ofthe-art output, cellulose ionogel has demonstrated advanced applications in various scenarios in the Internet-of-Things era, while the weak mechanical strength is significantly challenging. To address this limitation, we developed a simple self-crosslinked stagey of cellulose molecules by triggering the chemical reactions of the hydroxyl and dialdehyde groups. Such chemical bonds between cellulose molecules create the tough selfcrosslinked cellulose-ionogel (SCCell-ionogel), which demonstrates super high strength of 4.23 MPa with 540 % improvement, toughness of 1.36 MJ/m3 with a 900 % increase. In addition, the resultant SCCell-ionogel also features high transmittance (93 %) and desirable biodegradation. The self-crosslinked strategy paves the way for constructing high-performance, advanced ionogel of natural polymer for next-generation smart materials.

Abstract ：
Nanofluidic membranes composed of polymers and metal-organic frameworks (MOFs) are considered ideal for efficiently harvesting salinity gradient energy from global estuaries due to their well-defined nanochannels and surface charge. However, developing a polymer/MOF membrane that simultaneously combines excellent mechanical strength, scalability, high surface charge density, and porous structure remains a significant challenge. Here, we demonstrated a hybrid nanofluidic membrane by deconstructing charged cellulosic fibers (CCF) into charged cellulose molecules (CCM) and then tandemly connecting imidazolate molecular sieve framework-8 (ZIF-8). In this regard, the CCM/ZIF-8 nanofluidic membrane inherits a high surface charge density of CCF (-44 mV for zeta potential), abundant-angstrom/nanopore distinction of ZIF-8 (1540.5 m(2)/g for specific surface area and sub-nanometer pore size), and thus demonstrates excellent chemical and structural uniqueness, and superior robustness (similar to 25 MPa), high stability (stable for over 30 days in acidic, alkaline, and seawater environments) and scalability. As a result, our CCM/ZIF-8 membrane enables an excellent cation selectivity (t(+) of 0.82) and correspondingly high power density of up to 8.7 W/m(2) in KCl system (0.01/0.5 M salinity gradient, testing area of 0.075 mm(2)) and stably output over 60 days. This study provides a promising strategy for constructing high-performance polymer/MOF nanofluidic membranes for advanced selective ion transport, beyond salinity gradient energy conversion.

Abstract ：
Transparent flexible heaters attract great attention due to their potential applications in smart windows, wearable electronics, hand warmers, etc. Here, we present a highly flexible cellulose/zinc oxide/indium tin oxide (CZI) film heater, which was prepared by spinning coating of zinc oxide (ZnO) solution on cellulose film followed by magnetron sputtering of indium tin oxide (ITO). The CZI film exhibits a high visible light transmittance (80.3%), low resistance (7.3 Omegasq-1), and good thermostability. As connected to the circuit, the CZI film showed an excellent Joule heating performance even after multiple repeated bending tests. The temperature of the CZI film could increase from room temperature to 89 degrees C within 2 min under the working voltage of 6 V. Prompted by these versatile properties, and we demoed the application scenarios of this CZI film heater in thermochromism, deicing, and defogging to enlighten for the application of this film material in sensors or smart windows.

Abstract ：
Flexible hybrid nanogenerators (HNGs) have received significant attention for their potential in harvesting mechanical energy to power portable and miniaturized portable devices. This work presents a method to fabricate flexible, durable and biodegradable electrospun polydopamine@barium titanate/cellulose acetate (PDA@BTO/CA) nanofiber films. This design integrates polydopamine (PDA) and piezoelectric barium titanate (BTO) nanoparticles within a flexible cellulose acetate (CA) matrix to enable self-powered wearable biomonitoring. The inclusion of PDA enhances the physical adhesion between BTO and CA, resulting in a significant 40% increase in voltage output. Notably, the PDA-modified composite PDA@BTO/CA demonstrates remarkable durability over 15,000 cycles and effectively detects a range of human motions (such as fist clenching, wrist bending, elbow movement, walking, running and jumping), transducing them into stable, precise electrical signals. Intriguingly, the hybrid nanogenerator device exhibits robust performance in extreme conditions, including underwater and high or low temperatures, while maintaining its good biodegradability. This work paves the way for advanced self-powered wearable biosensor devices capable of precise and reliable human motion monitoring.

Abstract ：
Solar-driven evaporators have emerged as a sustainable strategy for water purification and energy harvesting. Designing advanced systems that achieve high evaporation performance, long-term operational stability, and resistance to salt crystallization remains a significant challenge. In this study, an innovative Janus membrane is proposed that addresses these challenges, featuring a super hydrophilic cellulose nanofiber (CNF)@Hexadecyl Trimethyl Ammonium Bromide (CTAB)-MXene layer and a superhydrophobic polytetrafluoroethylene (PTFE) layer. CTAB modification of MXene enhances its interlayer spacing and specific surface area, enabling rapid water transport and efficient solar energy absorption of the CNF@CTAB-MXene layer. A PTFE layer is sputter-deposited onto CNF@CTAB-MXene layer, effectively preventing salt accumulation and membrane fouling, with plasma pre-treatment ensuring excellent interfacial bonding between these two layers. Under 1 sun illumination, the CNF@CTAB-MXene/PTFE Janus evaporator achieves a remarkable evaporation rate of 1.51 kg m(-2) h(-1) with outstanding salt resistance. The synergy between superhydrophilic and superhydrophobic layers facilitates efficient water transport while maintaining long-term stability without performance degradation. Additionally, the evaporator generates a voltage of 343.8 mV during thermoelectric power generation, and its unique design allows electricity generation from wind energy at night. This integrated system provides an advanced and durable solution for water-power co-generation, offering practical benefits for off-grid or remote regions.

Abstract ：
以毛竹为原料，采用预水解-硫酸盐法制备竹溶解浆，探究了预水解时间、蒸煮保温时间以及用碱量对竹材半纤维素和木质素降解溶出效果的影响。结果表明，预水解处理可以有效溶出竹材中的半纤维素，延长预水解时间可以大幅度降低竹材中半纤维素含量、增加水解液中单糖和总糖质量浓度，实现半纤维素的有效脱除；同时，溶出半纤维素使竹材的孔洞数量增加，结构松散，有利于后续蒸煮阶段药液渗透和木质素降解溶出。经预水解时间160 min的条件处理，竹材的纤维素含量为57.4%、半纤维素含量为7.2%、得率为66.8%，其水解液中木糖单糖和木糖总糖质量浓度达到最大值，分别为12.9和23.1 g/L。在硫酸盐法蒸煮过程中，提高用碱量和延长蒸煮保温时间，均可以实现竹溶解浆中木质素和半纤维素的脱除，从而降低竹溶解浆的卡伯值和聚戊糖含量、提高其α-纤维素含量。在用碱量（以NaOH计） 20%、硫化度27%、液比1∶4、蒸煮温度170℃、蒸煮保温时间90 min的条件下，所得竹溶解浆的卡伯值为7.5、聚戊糖含量为2.1%、α-纤维素含量为90.8%、黏度为740 mL/g。
