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 ：
A flow system featuring a circumferentially impinging jet distributor (CIJD) coupled with coiled tubes was designed for high-throughput excellent mixing. The study investigated the effects of channel Reynolds number (Re-c), pore Reynolds number (Re-p), and Dean number (Dn) on the single-phase flow and different-scale mixing characteristics. Five flow regimes in the CIJD were identified at the range of 3.16 <= Re-c <= 316.3, including separated flow, squeezed flow, symmetric four-vortex flow, transitional flow, and asymmetric four-vortex flow. High-energy impinging jets promoted vortex entrainment, expanding the fluid contact interface. The extension of leg vortices and the emergence of secondary vortex pairs effectively enhanced mixing. As Re-c further increased, the concentration distribution in the CIJD tended to be uniform and challenging to quantify. Therefore, micro-mixing time t(m) = 0.97-58.4 ms was determined using the Villermaux-Dushman reaction system at the ranges of 177.2 <= Re-c <= 1063.4 and 265.3 <= Re-p <= 1591.6, and its correlation was established. Tracer pulse-response technique was employed to measure residence time distribution and P & eacute;clet numbers (Pe = 9.1-191.1) in the flow system at the range of 3.0 <= Dn <= 1797.4. The axial dispersion was analyzed from the perspectives of diffusion-dominated and convection-dominated on radial mixing. This easily regulated flow system, in which single-phase flow and multi-scale mixing are comprehensively characterized, holds practical value for mass transfer and reaction process intensification.

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 ：
Flow chemistry is widely valued for its enhanced transport properties and safety, but scaling up while maintaining the advantages of the microenvironment in small-scale systems remains challenging. We addressed this by developing a novel tube-in-tube millireactor with a multi-hole jet inlet and deflectors, designed to maintain consistent flow regimes and optimize micromixing, residence time distribution (RTD), and heat transfer at various scales. The reactor increases flux by enlarging tube diameters and incorporating micro-holes and deflectors, all while maintaining a constant annular space. This design, validated through both CFD modeling and experimental results, maintains consistent fluid flow and excellent transfer properties, achieving micromixing time below 2 ms at Re-h > 2000, a plug-flow-like RTD profile, and a heat transfer capacity up to 12.4 times greater than conventional designs. This study presents a simple, scalable approach to millireactor design, combining "number-up" and "size-up" strategies, offering a cost-effective solution for industrial applications.

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.

Abstract ：
Liquid-liquid mass transfer is crucial in chemical processes like extraction and desulfurization. Traditional tube-in-tube millireactors often overlook internal flow dynamics, focusing instead on entry modifications. This study explores mass transfer enhancement through structured inserts (twisted tapes, multi-blades) and inlet designs (multi-hole injectors, T-mixers). Using high-speed imaging and water-succinic acid-butanol experiments, flow patterns and mass transfer rates were analyzed. Results show annular and dispersion flows dominate under tested conditions with structured inserts lowering the threshold for dispersion flow. Multi-hole injectors improved mass transfer by over 40% compared to T-mixers in plain tubes, while C-tape inserts achieved the highest volumetric mass transfer coefficient (2.43 s-1) due to increased interfacial area and droplet breakup from energy dissipation. This approach offers scalable solutions to enhance tube-in-tube millireactor performance for industrial applications.
