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 ：
Silicon (Si) is a promising anode for high-energy-density batteries, but its similar to 300 % volume expansion causes particle fracture and electrode instability. Effective binders are essential for maintaining electrode integrity. Inspired by the adhesion mechanism of natural ivy, we developed a small-molecule-enhanced polymer binder derived from phosphorylated cellulose nanocrystals (PCNCs) and acrylic acid rosin to enhance the electrochemical and mechanical performance of Si anodes. PCNCs, with their high aspect ratio and surface activity, construct an interconnected three-dimensional (3D) network within the polymer matrix, reinforcing structural stability. Additionally, phosphate groups promote water-based polymer compatibility and ion transport, facilitating efficient lithium-ion conduction. Acrylic acid rosin mimics the adhesion mechanism of Parthenocissus tricuspidata, establishing strong hydrogen bonds, ion-dipole interactions, and covalent crosslinking with Si particles. This incorporation also forms a unique "soft outside, rigid inside" topology, buffering stress, protecting the solid electrolyte interface (SEI), and synergizing with polyacrylic acid (PAA) to form a robust network. The binder provides an excellent electrochemical performance, achieving a high initial coulombic efficiency (86.85 %), superior ionic conductivity (18.825 mS/cm(2)), and remarkable cycling stability at high silicon loading (maintaining 1272 mAh/g after 100 cycles at 0.2C). Its green synthesis and scalability offer a sustainable path for next-generation Si anodes.

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 ：
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 ：
Dissipative smart binders hold great potential for flexible electronics and energy storage, but achieving synergistic regulation between energy dissipation and structural reinforcement remains challenging, particularly in balancing high strength, tunable toughness, and multifunctional integration. Here, a dissipative smart binder with a dual-channel responsive mechanism is developed to enable dynamic regulation of energy dissipation and rigidity enhancement through the synergistic effects of slip relaxation and conformational locking. Centered on Fe2(+)/Fe3(+) dynamic coordination, the binder incorporates control via the intricate and rigid rosin architecture and a hierarchy of distinct bonding mechanisms, thereby enhancing its capacity for both rapid energy dissipation and strain-triggered reinforcement. Sodium alginate serves as a continuous phase framework, reinforced by phosphorylated cellulose nanocrystals, conformation-locking segments of acrylic acid rosin, and a multivalent coordination network that enables this strain-triggered state transformation. The binder exhibits a soft-to-rigid transition with a strain-rate-sensitive hardening effect, increasing modulus up to 98 000 times and fracture energy from 104.51 to 272.34 MJ m-3. Applied in silicon anodes, it maintains 2476.5 mA h g-1 after 100 cycles at 0.2C, with ionic conductivity reaching 25.240 mS cm-1, an eightfold increase over the unmodified system. The composite network effectively mitigates structural degradation, binder fatigue, and interfacial instability caused by silicon volume expansion.

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.
