To identify suitable extractants for extractive enhanced glycerol-CO2 carbonylation, liquid–liquid equilibrium data were determined for glycerol–glycerol carbonate systems with 2-pentanone, cyclohexanone, and 4-methyl-2-pentanone at 423.2, 433.2, and 443.2 K under a pressure of 1.5 MPa. The efficacy of the three extractants in the extraction of glycerol carbonate from glycerol was evaluated using distribution coefficients and extractive selectivity. Among the extractants, cyclohexanone possessed the highest distribution coefficient (>1) and superior extraction capability, while 4-methyl-2-pentanone exhibited the best selectivity for glycerol carbonate over glycerol. The liquid–liquid equilibrium data were then correlated using the Non-Random Two-Liquid (NRTL) model, and the corresponding binary interaction parameters were determined. The regressed parameters effectively reproduced the phase equilibrium trends observed for all studied systems. This work provides fundamental data and parameters for the selection of extractant to enhance the glycerol-CO2 carbonylation through extractive reactions as well as for subsequent process development and optimization for the carbonylation.

Chiral separation of D- and L-Serine is of great value in the fields of biopharmaceuticals. For this purpose, a D-Serine imprinted polymer was prepared by precipitation polymerization with the aid of deep eutectic solvent (DES) and crowding agent (polymethyl methacrylate, PMMA). The preparation conditions were optimized by a L 9 (3 4 ) orthogonal design. Structure characterization was performed by the FTIR, SEM, AFM and XPS techniques and adsorption selectivity and separation efficiency for this imprinted material investigated. The results showed that under the conditions of pH 5.0 and 303 K, the polymer exhibited maximum adsorption capacity, reaching 121.4 mg g -1 , with a selectivity factor as high as 11.87. When this D-serine-imprinted material was used as a chromatographic stationary phase to separate a mixture of D- and L-serine, the resolution achieved was 1.765, demonstrating high chiral separation efficiency. The high adsorption selectivity for the novel imprinted material might result from the synergistic effect of deep eutectic solvent with macromolecular crowding reagent during the preparation of the imprinted materials. One hand, deep eutectic solvent can stabilize the zwitterionic form of D-Serine ( + H 3 N-CH(CH 2 OH)-COO - ) and hence enhance the ionic interactions between the template and functional monomers and the stability of template-functional monomer complexes; on the other hand, crowding agents significantly improved the binding efficiency between the functional monomer and the template molecules during the pre-assembly stage through the "excluded volume effect". This synergy promotes to form higher density and more precise specific recognition sites during the synthesis of the imprinted polymer and to improve the adsorption selectivity of the material obtained.

This study fabricated a thermally self-cleaning nanofiltration membrane through molecular design and multi-scale assembly. PNIPAM-PEI microgels, synthesized by grafting PNIPAM and PEI, were deposited on a PPTA ultrafiltration substrate via layer-by-layer self-assembly. The deposition cycles were systematically optimized, followed by interfacial polymerization to form a polyamide separation layer. Characterization confirmed that five deposition cycles yielded a compact thermo-responsive intermediate layer and resulted in an interpenetrating [PEMs-PNIPAM]-PA structure. The resultant composite NF membrane exhibited excellent separation performance, with rejections of CaCl 2 and MgSO 4 reaching 97.3 % and 98.7 %, respectively, at 25 ℃, along with intelligent thermo-responsive behavior. When heated above the LCST, dehydration and contraction of the PNIPAM core drove the expansion of PA layer pores, activating a “pore expansion” self-cleaning mechanism, with full structural regeneration upon cooling. A 180-hour long-term test verified that high-temperature backwashing at 60 ℃ effectively restored the flux and retention of the fouled membrane. This work offers a new strategy for developing smart nanofiltration membranes with self-cleaning capability.

Renewable and short-season bamboo is a potential feedstock to produce pyrolytic sugars (e.g., levoglucosan) that can be upgraded into liquid fuels and chemicals. However, cellulose in bamboo is tightly intertwined with lignin and hemicellulose, forming a high recalcitrance and complex composition, resulting in hindering the effective release of levoglucosan during fast pyrolysis. The novel route of bamboo pretreated by deep eutectic solvents (DESs) coupled with fast pyrolysis was proposed for producing pyrolytic sugars. The results showed that the bamboo pretreated by choline chloride (ChCl)/formic acid (FA) produced the levoglucosan yield of 198.6 mg/g via fast pyrolysis, increased by about 43 times as compared to raw bamboo, while the relative contents of phenols and acids were significantly reduced. The characteristic analysis showed that the activation energy of the pretreated sample is in a direct proportional relationship with the crystallinity index. The change of crystallinity index and removal of lignin and AAEMs promoted the levoglucosan formation. This work provides an effective route to convert highly resistant lignocellulose into pyrolytic sugars via fast pyrolysis.

Photochemical organic synthesis has emerged as a prominent and important synthetic methodology in recent years. However, conventional photosensitizers are often expensive and require multi-step synthesis for their preparation. This study utilizes natural flavonoids extracted from citrus peel (Tangeretin, Nobiletin, and Sinensetin) as photocatalysts to achieve the photooxidation of alkenes. Conversion rates of 53.7% for styrene and 66.1% for cyclohexene were attained. Reaction Mechanism Generator (RMG) simulations revealed that alkenes undergo reaction pathways mediated by singlet oxygen or oxygen-free radicals to form the corresponding products, a finding corroborated by a series of control experiments and EPR. These flavonoid compounds exhibit Aggregation-Induced Emission (AIE) characteristics. Upon encapsulation with saponins to form nanoparticles, the conversion rate for cyclohexene was further enhanced to 86.0%. Furthermore, this system successfully achieved the efficient oxidation of benzyl alcohol in an aqueous solvent (52.4% conversion, >99% selectivity). This work establishes a comprehensive green chemistry system encompassing the light source, catalyst, and solvent. The proposed strategy offers a novel approach to the development of natural photocatalysts and sustainable organic synthesis.

Heterointerface engineering based on the built-in electric field (BIEF) for guiding the construction of nanohybrids has emerged as a feasible strategy to enhance interfacial polarization and amplify the electromagnetic energy attenuation capability. Herein, we have designed a MoS 2 hollow nanospheres (HNS)/reduced graphene oxide (rGO)/Ti 3 C 2 T x /TiO 2 composite aerogel with multiple heterointerfaces. Comprehensive experimental characterization and density functional theory calculations, reveal that the 1T/2H-MoS 2 HNS and TiO 2 derived from the self-oxidation of Ti 3 C 2 T x serve as semiconductor phases to establish effective Mott-Schottky contacts with the conductive rGO phase, thereby constructing a double BIEFs system. Under alternating electromagnetic fields, the triggered BIEFs rationally tunes the electron transport behavior at the heterointerfaces, enhancing the polarization relaxation phenomenon. The 3D network structure of the aerogel can significantly enlarge the contact area of BIEF and enhance the Mott-Schottky effect. As anticipated, the prepared MSGM-10% composite aerogel demonstrates a maximum effective absorption bandwidth (EAB max ) value of 6.56 GHz and a minimum reflection loss (RL min ) value of −67.50 dB at an extremely low filling ratio of 1.50%. Additionally, aerogel features light weight, good hydrophobicity, and stable thermal insulation performance, showcasing remarkable environmental adaptability and promising broad application prospects in electromagnetic protection and military stealth technologies.

The detection of acetone holds significant importance for both non-invasive diabetes screening and industrial safety monitoring. In this work, novel ZnFe 2 O 4 /ZnO hollow core-shell nanospheres were synthesized via a two–step hydrothermal method for acetone detecting. The sensor performance was optimized by precise control the film thickness. Compared with pure ZnO and other samples, ZnFe 2 O 4 /ZnO with the optimal shell thickness exhibited superior acetone sensing performance, showing a response of 38.1 toward 100 ppm acetone at a lower operating temperature of 200 °C, which is more than three times higher than that of pure ZnFe 2 O 4 . The sensor also demonstrated excellent selectivity, rapid response and extremely low detection limit (0.08 ppm). The improved acetone sensing performance is attributed to the synergistic effect of heterojunction and the highly active Zn-terminated surfaces. Optimizing the ZnO shell thickness balances gas diffusion with maximized active surface exposure, thereby fully utilizing both mechanisms for superior sensitivity.

As an important and free amino acid, taurine (Tau) shows extensive application in pharmaceuticals. The coexistence of inorganic salts during the production process affects the purity and quality of Tau. Present study firstly described a novel method to separate Tau and Na2SO4 by forming deep eutectic solvents (DESs) in situ. Ethanolamine (MEA) was chosen as the optimal hydrogen bond donor to pair with Tau. After removal of Na2SO4, taurine was stripped out from in situ DES using n-propanol as reverse solvent with the yield of 98% and trace impurities (Na2SO4 and NaCl contents less than 13.70 mg•g -1 and 12.93 mg•g -1 , respectively). On the optimized parameters, the Tau purification and separation process were further elucidated using quantum chemical calculations and molecular dynamics simulations together. Results showed the interaction energy of 116.1 kJ/mol between MEA and Tau, confirming the superiority of Tau purification using DES in situ.

Skin-like soft electronics exploiting gels containing biomass-derived components raise increasing research attention, in which multifunctional lignin has been extensively explored. Nevertheless, elevating the lignin loading usually sacrifices the performance, limiting their application potentials. Herein, we develop a unique polymerizable deep eutectic solvent (PDES) consisting of a quaternary ammonium monomer and lactic acid to incorporate with high-density lignosulfonate (LS) of > 20 wt.% and address the performance trade-offs. The lignin-induced self-catalytic polymerization associated with electrostatic assembly enables room temperature gelation within < 5 min and ambient-air micropatterning. Remarkably, the anionic LS and polycationic matrix affording multiple non-covalent interactions drastically enhance the mechanical strength to > 1 MPa and versatile adhesion up to > 500 kPa, meanwhile allowing self-healing, photothermal, and antibacterial capabilities. Such LS-PDES eutectogels also permit ion conduction (> 3 mS cm −1 ) and superior environmental adaptivity over −80°C to 100°C. Thus, employing the in situ polymerization between electrodes, rapid prototyping of bend-/impact-resistant flexible supercapacitors is demonstrated to power wearable sensors. More importantly, it facilitates the production of miniaturized soft organic electrochemical transistor (OECT) arrays, whose performance can be well maintained under deformed and extreme temperature conditions. This high-lignin-density eutectogel platform paves a straightforward route towards printed soft ionotronics, bioelectronic interfaces, and brain-inspired computing.

Compared to organic nanofiltration (NF) membranes, ceramic NF membranes exhibit higher stability under harsh conditions such as extreme pH and elevated temperatures. γ-Al 2 O 3 is commonly employed as an interlayer in multilayer ceramic NF membranes, but it is restricted to relatively mild conditions. In this study, on a macroporous alumina hollow fiber support, a boehmite sol coating is transformed from γ-Al 2 O 3 to α-Al 2 O 3 at a reduced phase-transformation temperature under the induction of TiO 2 , forming a uniform ultrafiltration interlayer for the fabrication of SiO 2 -ZrO 2 separation layer in a single step. By dual regulating the TiO 2 doping content in boehmite sol and sintering temperatures, the resulting SiO 2 -ZrO 2 /α-Al 2 O 3 NF membrane with a pore size of 1.4 nm demonstrates extended stability across a wide pH range of 1–13 under elevated temperatures. During the long-term dynamic textile wastewater treatment test, it maintains stable permeance and selectivity for over 24 h at pH 2/12 under 60 °C, significantly outperforming γ-Al 2 O 3 -supported SiO 2 -ZrO 2 membranes. Meanwhile, it displays a permeance of up to 18 LMH/bar and superior dye desalination performance (CR: 99.23%, NaCl <12%). This optimization strategy not only enhances the stability of SiO 2 -ZrO 2 NF membranes with the aid of an α-Al 2 O 3 interlayer but also provides a simplified route for their fabrication.

This work presents a molecular-to-structural strategy for fabricating high-performance CL-20-based composite energetic materials using direct ink writing (DIW). A poly(vinyl alcohol)/poly(acrylic acid)/modified potassium titanate whisker (PVA/PAA/ M-PTW) interpenetrating polymer network (IPN) was designed to simultaneously enhance mechanical strength and reduce mechanical sensitivity. The hydrogen bonding–covalent crosslinking–filler reinforcement mechanism ensured uniform dispersion of CL-20 crystals and strong interfacial adhesion within the polymer matrix. Surface modification of PTW with 5 wt% KH-550 improved compatibility with the IPN, yielding printed structures with excellent form accuracy and adhesion to aluminum substrates (0.961 MPa). The optimized composite exhibited high compressive strength (16.77 MPa) and reduced impact and friction sensitivities compared with ε-CL-20 and submicron CL-20 samples. It achieved stable detonation wave transmission within a 90°-160° corner range in a 1.2 × 1.2mm charge slot, with the critical detonation size reaching 0.3m × 0.3mm. The measured detonation velocity of 7267.9m/s (83.2% of theoretical). These results demonstrate that the DIW-based PVA/PAA/M-PTW system enables the precise construction of high-strength, low-sensitivity energetic composites with reliable detonation performance, providing a promising pathway for advanced micro-scale energetic devices.

This study investigated the interaction between trans-cinnamaldehyde (TC) and ovalbumin (OVA) at the molecular level and its impact on the gel properties of OVA. Multispectral analysis, molecular docking, and molecular dynamics simulations were employed to elucidate the underlying mechanisms. At room temperature, TC bound to OVA mainly through non-covalent interactions, characterized by static quenching, which consequently altered the secondary structure of OVA. Moderate TC incorporation significantly enhanced the textural properties of thermally induced OVA gels, with hardness, chewiness, and gumminess increased by 39.4%, 28.0%, and 34.9%, respectively (P < 0.05 ). In addition, TC treatment improved the gel's water-holding capacity (by 4.38%), optimized water distribution, and promoted a more uniform microstructure. These improvements were primarily attributed to TC-induced Schiff base formation and non-covalent interactions, which collectively modulated intermolecular forces within OVA. Overall, this study provides novel insights into the use of spice-derived compounds to enhance the structure and functional quality of protein-based foods.
