Precious metals are critical to electronics and catalysis because of exceptional conductivity, corrosion resistance, and unique physicochemical properties. However, the surge in demand driven by the expansion of the electronics and automotive industries has intensified the environmental and economic pressures associated with the accumulation of precious metal waste. Photocatalysis has emerged as a promising strategy for resource recovery; however, its dependence on toxic acetonitrile solvents limits industrial applicability. Here, we present a photocatalytic-assisted solvometallurgical approach employing ethylene glycol-a benign, low-volatility solvent-to achieve complete leaching of precious metals from various industrial waste catalysts within 10 min. Field-scale experiments conducted under solar irradiation processed 125 g of spent catalyst in a single batch, yielding 0.45 g of high-purity palladium (>99%). This approach expands the solvent scope for photocatalysis, eliminates the need for hazardous reagents, and facilitates solar-powered operation, thereby offering a practical and scalable pathway for sustainable precious metal recycling.

Objective This study aimed to develop polyethylene glycol (PEG)-modified liposomes (PG-1-Ls) to overcome the poor oral bioavailability and burst release of phenolic glycoside 1 (PG-1), an anti-aging compound isolated from Moringa oleifera seeds. Methods PG-1-Ls were preparedby thin-film dispersion and optimized via a Box-Behnken design. The formulation wascharacterized for particle size, encapsulation efficiency (EE%), drug loading (DL%), andmorphology. Stability, in vitro release in four media, and safety in zebrafish were evaluated. Pharmacokinetics were studied in rats, and anti-aging efficacy was assessed in a D-galactose-induced zebrafish model by measuring β-galactosidase activity. Results The optimized PG-1-Lswere spherical and uniform (154.6 ± 3.8 nm), with high EE% (88.29%) and good stability. They successfully eliminated the initial burst release of PG-1, demonstrating sustained release profiles. In rats, PG-1-Ls increased the oral bioavailability (AUC) by 6.25-fold and the peak concentration(C~max~) by 3.9-fold compared to free PG-1. The formulation also showed improved safety in zebrafish. In the aging model, both PG-1 and PG-1-Ls significantly reduced β-galactosidaseactivity, with PG-1-Ls exhibiting superior efficacy comparable to the positive control. Conclusion PEGylated liposomes significantly enhance the sustained release, oral bioavailability, safety, and in vivo anti-aging activity of PG-1, representing a promising delivery system for its application.

Lignin condensation and the recalcitrance of lignocellulose during conventional fractionation limit their valorization. Herein, we develop a tunable ternary deep eutectic solvent (TDES) composed of guanidine hydrochloride, lactic acid, and ethylene glycol for efficient fractionation of moso bamboo. By modulating the EG content, 74.3% delignification was achieved while preserving lignin structure, as confirmed by a β‑O‑4 content of 26.3/100 Ar (61.3% retention). Lignin nanoparticles self‑assembled into uniform lignin nanobottles (LNBs) with size controlled by lignin structure. Moreover, the preserved structural integrity enabled a high bio‑oil yield of 39.7 wt%. 4‑Vinylphenol was identified by Py‑GC/MS as the dominant product. Strong positive correlations were observed between β‑O‑4 content and both LNBs size and bio‑oil yield. Enzymatic saccharification of the treated residue achieved up to 94.4% glucose conversion. This work establishes a clear structure‑property relationship and presents a “structure‑first” strategy for dual‑pathway lignin valorization into nanomaterials and fuels.

The efficient and highly selective electrocatalytic oxidation of propylene to propylene glycol (PG) is a key challenge in green chemistry. Here, we synthesized uniform palladium‑silver alloy mesoporous nanospheres (PdAg MNs) via a micelle-directed approach. Compared to Pd MNs, the PdAg MNs showed enhanced performance, achieving a Faradaic efficiency (FE) for PG of 50.7% and 87.6% selectivity at 1.15 V. During reaction, surface Pd transforms into Pd 2+ /Pd 4+ species, boosting OH binding energy and optimizing surface OH coverage. This promotes the *OH-mediated consecutive hydroxylation pathway. Density functional theory (DFT) studies elucidated that Ag incorporation optimizes the adsorption/desorption energetics of propylene and PG, accelerates water activation kinetics and the *OH generation rate, and maintains a high *OH surface coverage on the PdAg MNs. This work achieves efficient PG synthesis by promoting the consecutive hydroxylation pathway through regulation of the *OH coverage during propylene oxidation, providing deeper mechanistic understanding into olefin oxidation.

Perovskite photodetectors have attracted considerable attention due to their excellent optoelectronic properties and low-cost solution processability. However, the practical application of formamidinium lead iodide (CH(NH 2 ) 2 PbI 3 , FAPbI 3 ) based devices is severely hindered by high defect densities, phase instability, and non-radiative recombination losses. Herein, we demonstrate a simple and effective strategy to simultaneously address these challenges by incorporating polyethylene glycol (PEG) as a multifunctional additive into the FAPbI 3 precursor solution. Systematic optimization reveals that an optimal PEG concentration (2 mg/mL) significantly improves film crystallinity, enlarges grain size and reduces trap density, as evidenced by XRD, SEM, and SCLC analyses. The synergistic interaction mechanism was investigated by combining XPS and FTIR spectroscopy. Consequently, the optimized PEG-2 photodetector exhibits a ∼30% reduction in dark current, a ∼750% enhancement in photocurrent, and a ∼13-fold increase in on/off ratio compared to the pristine device. Both responsivity and detectivity are substantially improved across the visible spectrum, achieving a responsivity of 3.8 mA/W and a specific detectivity of 9.76 × 10 10 Jones. This work establishes PEG as a low-cost, multifunctional additive for defect passivation and morphology control in FAPbI 3 perovskites, offering a simple strategy toward high-performance, stable photodetectors and molecular guidance for rational polymer design.

For engineering applications such as high-heat-flux thermal management, nanofluids must simultaneously exhibit excellent long-term stability and suitable rheological and interfacial properties to meet practical operating requirements. Accordingly, this study investigates TiO 2 /propylene glycol nanofluids and constructs organic grafting layers on TiO 2 surfaces using γ -methacryloxypropyltrimethoxysilane, denoted as KH-570 and n -octyltriethoxysilane, denoted as OTES, to systematically compare the modification effects of the two grafting systems. TGA, FTIR and TEM analyses confirm the formation of stable grafted layers on TiO 2 , and the grafting efficiency shows a rise–fall trend with increasing silane concentration, with the maximum values reaching 7.954% for KH-570 and 6.268% for OTES. Stability tests indicate that the KH-570-modified nanofluids exhibit superior dispersion stability: over a 50-day quiescent period, the minimum clear-supernatant thickness is 1.205 mm, which is markedly lower than 4.123 mm for the OTES-modified system. Rheological measurements show that at 40 ∘ C over a shear-rate range of 75–450 s − 1 , all samples display shear-thinning behavior, and increasing grafting efficiency leads to higher viscosity and more pronounced shear-thinning. In terms of interfacial properties, the introduction of surface functional groups causes the surface tension to decrease significantly with increasing grafting efficiency for both silanes. Based on the experimental data, empirical models were developed for the two modified nanofluids, yielding R 2 values no lower than 0.98 and mean relative errors controlled within 0.247%.

Paclitaxel (PTX), as a broad spectrum and highly efficient antitumor drug, occupies an irreplaceable position in clinical cancer therapy. However, despite its definite therapeutic efficacy, its clinical application is largely limited by its extremely poor water solubility. Here, we report a facile method for encapsulating PTX into silk fibroin nanoparticles (PTX-SFNPs) using low molecular weight polyethylene glycol (L-PEG) as a solubilizer and high molecular weight polyethylene glycol (H-PEG) as an emulsifier and dehydrating agent, without adding any toxic organic solvents, surfactants, or other toxic agents. The efficiency at the volume of the reactor and processing time was 23.63 g/L, significantly higher than the desolvation method in ethanol and acetone. The PTX-SFNPs with a diameter of 100−300 nm exhibited promising drug loading (5.99 ± 0.28%) and encapsulation efficiency (30.91 ± 2.64%), excellent biocompatibility, and sustained drug release. In vivo studies using a mouse model with glioblastoma showed significant tumor inhibition without the systemic toxicity typical of traditional PTX formulations. Histological analysis confirmed the effective tumor penetration and biocompatibility of the nanoparticles. These findings suggest that PTX-SFNPs provide a promising approach for targeted glioblastoma therapy with the potential for future clinical applications.

Tungsten–carbon catalysts were designed for pathway-controlled cellulose hydrogenolysis. • Complete cellulose conversion with tunable selectivity to ethanol or diols was achieved. • WO x -derived Lewis acidity promoted selective C–C bond cleavage of glucose. • Metal–oxide interfacial sites enabled deep hydrogenolysis toward ethanol formation. • SO 3 H-modified catalysts regulated acid–metal cooperation toward C3 diol production. Cellulose, as the most abundant renewable carbon resource, offers great potential for the sustainable production of low-carbon alcohols. However, its catalytic hydrogenolysis remains challenging due to the difficulty in controlling product distribution and reaction pathways. Herein, two tungsten–carbon–based catalytic systems were rationally designed to direct cellulose hydrogenolysis toward ethanol or 1,2-propylene glycol through site-dependent catalysis. A multifunctional Mo-Pt-WO x /WC catalyst was constructed for ethanol production, while a sulfonated Mo/WC-SO 3 H catalyst was developed for selective formation of 1,2-propylene glycol. Under optimized conditions (245 ℃, 2 h, 5 MPa H 2 ), complete cellulose conversion was achieved over Mo-Pt-WO x /WC, delivering a total low-carbon alcohol yield of 68.1C% with an ethanol yield of 57.8C%. In contrast, Mo/WC-SO 3 H enabled complete cellulose conversion with a high 1,2-propylene glycol yield of 62.9C%. Experimental characterization suggests that SO 3 H-derived acidity may promote cellulose hydrolysis, while Mo-containing surface species may facilitate glucose isomerization and retro -aldol C–C bond cleavage. Density functional theory (DFT) calculations further reveal that WO x -derived acid sites favor selective C–C bond scission of glucose, whereas deep hydrogenolysis of ethylene glycol to ethanol is kinetically favored at Pt-MoO x interfacial sites. This work provides a practical strategy for steering cellulose hydrogenolysis toward different low-carbon alcohols through rational active-site design, and offers guiding principles for the rational development of multifunctional catalysts for biomass valorization.

Superhydrophilic coatings are of broad interest for self-cleaning, oil–water separation, anti-fogging, and anti-biofouling applications. In this work, a transparent and mechanically robust PEG-grated superhydrophilic silica coating was fabricated on glass by combining sequential dip-coating with covalent surface functionalization. Polyethylene glycol trimethoxysilane (PEG-TMOS) was synthesized via a hydrosilylation reaction between trimethoxysilane (TMOS) and allyl polyethylene glycol (APEG). Acid-catalyzed silica (A-silica, ∼20 nm in diameter) and base-catalyzed silica (B-silica, ∼165 nm in diameter) nanoparticles were prepared through TEOS hydrolysis/condensation using HCl and NH 3 ·H 2 O, respectively. The coating was constructed by sequentially depositing A-silica and B-silica to build an adhesion-promoting interlayer and a roughness-enhancing top layer, respectively, followed by grafting PEG-TMOS on the surface of B-silica particles. Successful PEG grafting was confirmed by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS), and the coating achieved superhydrophilicity with a static water contact angle below 5° while maintaining high visible-light transmittance (∼95%). The coating also exhibited strong adhesion (Grade 0), pencil hardness of 3 H, and excellent abrasion durability, retaining hydrophilicity after 700 rubbing cycles. Functionally, the PEG-grafted surface remained clear under both steam (60 °C) and frost-to-ambient conditions and showed strong resistance to bovine serum albumin (BSA) adsorption. This scalable, chemistry-anchored strategy provides a practical route to high-clarity superhydrophilic coatings with durable anti-fogging and antifouling performance.

Nanofiltration (NF) for advanced drinking-water treatment has long been constrained by the need to remove contaminants while preserving beneficial mineral ions in health-oriented drinking water. Herein, an ethylene-glycol (EG)-regulated aqueous microenvironment was introduced to tailor the interfacial polymerization process. EG-mediated hydrogen bonding and modified interfacial thermodynamics jointly regulated piperazine diffusion, interfacial transport, and polymerization kinetics, producing polyamide NF membranes with enhanced negative charge surface density and a more uniform effective pore structure. Compared with the pristine membrane, the EG-20 membrane exhibited a thinner, more hydrophilic, and more negatively charged selective layer, together with a narrower pore-size distribution. The optimized EG-20 membrane achieved a permeance of 23.6 L m −2 h −1 bar −1 while maintaining Na 2 SO 4 rejection above 95.5%. In the treatment of natural surface water, dissolved organic matter removal reached approximately 92.1%, while partial passage of beneficial mineral ions was maintained, enabling effective organic contaminant removal with mineral preservation for health-oriented drinking water treatment. Moreover, high rejection of PFAS and antibiotics was maintained, mainly because steric exclusion and enhanced electrostatic repulsion compensated for the moderately enlarged effective pores. In addition, the membrane showed improved antifouling performance, as enhanced surface hydration and electrostatic repulsion reduced foulant adhesion and suppressed irreversible fouling. Overall, this microenvironment-regulation strategy provides a feasible route for developing NF membranes that integrate effective contaminant control, mineral preservation, and stable operation.

The catalytic hydrogenolysis of glucose to produce 1,2-propylene glycol (1,2-PG) has opened promising avenues for sustainable chemical production. However, traditional Ru-based catalysts suffer from issues such as high metal loading, poor dispersion, and a tendency to agglomerate under harsh conditions, leading to rapid deactivation. This work reports a highly dispersed, low-loading Ru catalyst supported on a magnesium–aluminum ferrite (MAFO) spinel to address these limitations. Strong covalent metal–support interactions (CMSI) between Ru species and the MAFO support not only achieve efficient stabilization of Ru nanoparticles but also promote their redispersion. Under optimized reaction conditions (518 K, 5 MPa H 2 , and 1 h), the Ru/MAFO catalyst achieves 100% glucose conversion and 59.3% selectivity to 1,2-PG. Notably, the catalyst maintains outstanding activity and stability after six consecutive reaction cycles. This study provides an efficient and robust catalytic strategy for 1,2-PG production from glucose, offering significant insights for designing high-performance and stable catalysts for biomass valorization.

The dissociation/reassociation kinetics and chain dynamics of telechelic ionomers synthesized from carboxylate-terminated poly(propylene glycol) with various alkali metal counterions (Na+, K+, Rb+, Cs+) are investigated to clarify their ion-size-dependent dissociation pathways. By combining broadband dielectric spectroscopy (BDS) and linear viscoelasticity (LVE), we find that the ionomers with Rb+ and Cs+ counterions exhibit clear Maxwellian-type terminal relaxation, indicating a uniform relaxation rate of all telechelic chains, likely through the dissociation of ion pairs as stickers. In comparison, ionomers with Na+ and K+ counterions exhibit sticky-Rouse-like relaxation behavior in the terminal region. This feature, given that each chain has two uniform stickers, is attributed to the continuous relaxation of a sequence of chains through dissociations of quadrupoles or even larger clusters that connect these chains.
