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 ：
Due to the features and wide range of potential applications, cellulose ionogels are the subject of extensive research. Green celluloses have been employed as a three-dimensional skeleton network to restrict the ionic liquids (ILs) toward advanced ion-conductive ionogels. Diversiform cellulose ionogels with desirable performances, via physical/chemical reactions between cellulose and ILs, have been harvested, which have the potential to emerge as a bright star in the field of flexible electronics, such as sensors, electrolyte materials as power sources, and thermoelectric devices. Herein, a review regarding cellulose ionogels in terms of fundamental types of cellulose, formation strategies and mechanism, and principal properties is presented. Next, the diverse application prospects of cellulose ionogels in flexible electronics have been summarized. More importantly, the future challenges and advancing directions to be explored for cellulose ionogels are discussed. © 2024

Abstract ：
Selective oxidation of polyol-containing cellulose is significant for the development of cellulose-derived functional materials. While conventional oxidation methods readily introduce aldehyde groups at the C2/C3 positions (accompanied by ring-opening of anhydroglucose units) or carboxyl groups at the C6 positions in cellulose, selective oxidation to generate aldehyde functionalities specifically at the C6 position remains challenging. Herein, we demonstrate that 2-Iodoxybenzoic acid (IBX) acts as an efficient and selective oxidant for converting the primary alcohol at the C6 position of anhydroglucose units to aldehyde groups under mild conditions. Monosaccharide model studies confirmed C6-specific oxidation. This method was successfully applied for the surface modification of microcrystalline cellulose (MCC, predominantly I beta allomorph) and bacterial cellulose (BC, mainly I alpha allomorph), achieving aldehyde contents of 0.96 and 0.93 mmol g-1, respectively, with 0.6 and 0.5 equiv of IBX per anhydroglucose unit. Crystallinity analysis showed that oxidation with IBX leads to a significant decrease of crystallinity but has a negligible effect on the cellulose allomorph. This study presents a novel approach for the preparation of C6-aldehyde cellulose, enabling precise, selective modification and advancing functional material development.

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.
