Abstract ：
Ultrathin membranes with fast solvent transport are promising in organic solvent nanofiltration. However, achieving high permeance for both polar and non-polar solvents remain challenging. Here we report ultrathin amphiphilic membranes (UAPMs) polymerized from hydrophobic terpenoid molecules and hydrophilic polyamines that enable fast and versatile solvent transport. The terpenoid carboxylic acid (TCA) in the organic phase react with polyethyleneimine (PEI) in the aqueous phase at the liquid-liquid interface, during which the glutaraldehyde is added into the aqueous phase to enhance the crosslinking of polymeric network and thus forming UAPMs. Regulating the ratio of hydrophilic to hydrophobic components allow for the precise manipulation of the surface polarity of UAPMs, rendering affinity to both polar and non-polar organic solvents. The increased PEI/TCA ratio also provides more amine sites to bind with the carboxylic monomers and thus generating denser and thicker membranes. The optimized UAPM demonstrates high permeance values of 175.9 L m- 2 h- 1 bar- 1 for polar ethanol and 116.5 L m- 2 h- 1 bar- 1 for non-polar n-hexane, with a molecular weight cutoff of 591 Da, which achieves 96.4 % rejection of Reactive Red in ethanol and 94.8 % rejection of Chlorophyll in n-hexane. Our structural design of UAPMs may pave a new avenue for engineering high-performance molecularseparation membranes.

Abstract ：
The development of efficient catalysts for rosin esterification is essential for advancing the high-value utilization of natural rosin, owing to the improvements in its processability. This study focused on the preparation of the magnesium oxide/N-doped biochar (B-MgO-N-C) from wood waste using a mechanochemistry-assisted strategy. Comprehensive characterizations revealed that ball milling together with nitrogen doping facilitated the incorporation of MgO into the carbon matrix, both of which contributed to the improved catalytic activity. The catalytic performance of B-MgO-N-C was then evaluated using the esterification of rosin with glycerol as a model reaction. After optimization, a 94.6 % rosin conversion was achieved at 230 degrees C over 4 h, outperforming the performance of both MgO-loaded biochar and N-doped biochar catalysts. The enhanced catalytic activity of BMgO-N-C can be attributed to the synergistic effect of in-situ embedded MgO and N-doping, which increases the number of active sites. CO2-TPD and NH3-TPD studies confirmed the importance of basic sites in promoting the esterification of rosin, whereas acidic sites might also contribute to this process. Moreover, recycling tests demonstrated that N-doping improved the stability of B-MgO-N-C. The catalyst also showed high rosin conversion when other alcohols were used. Accordingly, this work presents a straightforward strategy for designing metal oxides/N-doped biochar as advantageous catalysts for the esterification of rosin.

Abstract ：
The rising need for sustainable energy storage devices has prompted the advancement of eco-friendly electrode materials derived from renewable resources. The utilization of industrial byproducts for high-performance energy materials represents a promising approach toward cleaner production and a circular economy. This article introduces a sustainable synthesis route to produce a chitosan/wood-pitch-derived porous carbon material using wood pitch as the precursor, with systematic optimization of key parameters, including the chitosan content, activating agent amount, and temperature. Electrochemical characterization revealed that the optimized woodpitch-derived carbon material (CM-800 T) exhibited a high specific surface area (3457.2 m2/g) with an abundant microporous structure. The material demonstrated outstanding electrochemical performance with a specific capacitance of 303 F/g at a current density of 1 A/g, exhibiting minimal resistance to charge transfer and solution. After 5000 cycles at a current density of 10 A/g, it retained 91.5 % of its capacitance, indicating excellent cycling stability. To assess its practical application in supercapacitors, a direct ink writing (DIW) conductive composite ink was developed. Using 3D printing technology, an all-gel-state DIW-based micro interdigitated electrode supercapacitor with a 3D-interconnected layered porous structure was fabricated at room temperature, which exhibited outstanding electrochemical energy storage performance, excellent printability, superior rate capability, and good cycling stability. This article provides a cost-effective and eco-friendly method for preparing high-performance porous carbon materials and establishes a promising framework for the integration of woodpitch-derived carbon electrodes into advanced supercapacitor technologies.

Abstract ：
Loose nanofiltration (LNF) membranes based on interfacial polymerization (IP), such as polyester (PE) and polyamide (PA), are widely used in textile wastewater treatment. However, membrane fouling is unavoidable due to dye accumulation and salt scaling, resulting in a reduced membrane performance and reduced service life. Herein, we investigate the fouling behavior of two representative PE and PA LNF membranes, synthesized using quercetin and arginine as aqueous monomers via the IP technique, respectively. When the concentration factor (the ratio of the initial feed volume to the final concentrated volume) of the feed solution reaches 10 through the continuous process, comparing the fouling behavior of the PE and PA membrane, the water flux and Congo red/ NaCl selectivity of the PE membrane decreased by 62.8 % and 26.9 % respectively, and that of the PA membrane decreased by 55.5 % and 13.9 %. The severe fouling of the PE membrane was mainly because of the large pore size and rough surface. Then, four cleaning agents were employed (NaOH, HCl, NaClO, and acetone solution) to clean the PE and PA membranes. A NaClO solution (300 ppm) was most effective for cleaning the PE membrane, while a pH 11 NaOH solution worked best for the PA membrane. Finally, cleaning strategies for the fouled PE and PA LNF membranes after textile wastewater treatment are proposed. Through the batch process involving both fouling and cleaning, when the concentration factor of the feed solution reaches 10, the cleaning efficiency of the PE membrane and the PA membrane are respectively 12.3 % and 5.9 % higher than that of the continuous process. This study highlights the importance of selecting appropriate cleaning agents and optimizing the cleaning strategy in maintaining the long-term stability and performance of LNF membranes, providing theoretical guidance for the cleaning of loose PE and PA membranes.

Abstract ：
In this study, a novel proton-conducting film was strategically engineered by interfacial manipulation of green and sustainable biomass resources guanine and phosphorylated cellulose nanocrystals (PCNCs) within vermiculite layers. The interfacial engineering approach involved regulation of molecular interactions at the vermiculite-organic interface, whereby PCNCs were incorporated into the interlayers of guanine/vermiculite composites. This interfacial assembly process guided guanine to form tubular structures or ultrathin nanosheets architectures, enabling the fabrication of guanine/vermiculite-PCNCs (G/VMT-PCNCs) composite films with an active-site-rich and tightly interconnected network via a vacuum-assisted process. The rationally designed composite films exhibited excellent proton conductivity, which showed positive correlation with relative humidity (RH) and temperature, reaching 0.50 mS/cm at 25 degrees C and 97 %. Notably, the optimal composite film achieved a maximum proton conductivity of 1.15 mS/cm at 97 % RH and 80 degrees C. The interface-engineered structure endowed the humidity sensors based on this composite film with superior performance, including high sensitivity (31.82 Hz/%RH), small hysteresis (0.60 % RH), and rapid response/recovery times (36 s/5 s). The findings provide valuable insights into the design and fabrication of high-performance proton exchange films and humidity sensors, contributing to the advancement of sustainable clean energy technologies.

Abstract ：
Cellulose acetate (CA), a biomass-derived material for desalination membranes, faces challenges in nanofiltration-based desalination due to its weakly charged hydroxyl groups. Here we report gradient-charged CA membranes (GC-CAMs) engineered through the surface segregation of ionic covalent organic framework nanosheets (iCOFNs). Pre-evaporation drives sulfonated iCOFNs to migrate from the bulk to the surface due to the density difference between the nanosheets and CA solution, which creates a gradient distribution of iCOFNs and forms GC-CAMs via phase inversion. The charged nanosheets enriched on the front surface increase the membrane charge density from -0.89 to -1.13 mC m(-2) while decreasing membrane pore size from 0.74 to 0.68 nm, synergistically enhancing ion exclusion via electrostatic repulsion and size sieving. By positioning the front membrane surface downstream, salt rejection is further improved by mitigating the charge shielding effect. By regulating the pre-evaporation time and iCOFN content, the optimized GC-CAM achieves a Na2SO4 rejection of similar to 95 %, which is maintained at similar to 90 % over two months. When applied to natural water purification, it reduces total dissolved solids by similar to 83 % while moderately removing heavy metal ions. The proposed gradient structure offers a novel approach for the charge engineering of nanofiltration membranes.
