Phase engineering is a significant means of effectively enhancing catalytic performance. However, achieving continuous and precise phase control in intermetallic compounds remains a challenge, which has hindered the development of phase-dependent catalysis. In this work, we demonstrate continuous phase regulation and unveil the crucial role of phase rearrangement in the selective construction of nanocrystals. Through a mechanistic investigation, we uncovered a phase-dependent behavior governing the selective phase transformation during phase rearrangement. When a Pd-rich (Pd20Te7, the ratios of Pd/Te > 1) template was used, Pd20Te7 rearranged into PdTe. The Te vacancies generated in this process were occupied by Pb atoms, leading to the formation of a Pd–Pb alloy. Conversely, Te-rich template (PdTe2, the ratios of Pd/Te < 1) rearranged to PdTe, with the resulting Pd vacancies being occupied by Pb atoms to form a Pb–Te alloy. The customized interface in PdTe–PbTe significantly enhanced its formic acid oxidation reaction (FAOR) activity. The catalyst achieved a mass activity of 4.17 A mgPd–1 and a specific activity of 9.12 mA cm–2, surpassing commercial Pd/C by factors of 16.68 and 12.67, respectively. This work establishes a selective phase-regulation strategy to create customized nanostructures for diverse applications.

The molecular basis of deep eutectic solvent (DES)-mediated extraction of arbutin was investigated using a computational chemistry method for the first time to uncover the impressionable chemical functionality of DESs. The hydrogen-bonding interactions among hydrogen bond acceptors, hydrogen bond donors, and arbutin were investigated based on density functional theory, through electrostatic potential (ESP) distribution, molecular polarity index (MPI), independent gradient model based on Hirshfeld partition (IGMH), and atoms-in-molecules (AIM) analyses. ChCl/LA (1:3) exhibited superior extraction efficiency for arbutin among the examined DESs. The ESP distribution matching study revealed that CA, LA, Gly, and PG displayed a higher overall charge distribution compatibility with ChCl than UR. In the DES–arbutin systems, ChCl/LA (1:3) showed its strongest and most stable binding characteristic with arbutin, as evidenced by the optimal electrostatic matching and the highest MPI value with arbutin. IGMH analysis indicated that both the hydroxyl and carboxyl groups in LA endowed a stronger hydrogen-bonding interaction between arbutin and ChCl/LA compared to that between arbutin and ChCl/Gly and ChCl/UR. This was further supported by the fact that the absolute value of the interaction energy of ChCl/LA (1:3) (−30.33 kcal/mol) was higher than those of other DESs (−15.86 to −26.26 kcal/mol). Moreover, AIM analysis revealed that the highest bond critical point (BCP) electron density of ChCl/LA (1:3)–arbutin was at BCP 236 (O 1 ···H 34 O) = 0.0488 a.u., corresponding to a hydrogen bond energy of −10.1534 kcal/mol, indicating the strongest hydrogen bond interaction. These findings provide a novel molecular-scale rationale for designing effective DESs for natural-product extraction.

Nickel-ethylenediamine complexes ubiquitously present in electroplating effluents are highly toxic and recalcitrant contaminants hindering conventional wastewater treatment. To mitigate these severe environmental risks and bypass energy-intensive ligand-destruction processes, this study advances a closed-loop strategy directly repurposing these hazardous complexes into functional forward osmosis (FO) draw solutes for simultaneous wastewater purification and nickel recovery. Through rational coordination engineering, structurally well-defined nickel-monoethylenediamine (Ni-en) and nickel-triethylenediamine (Ni-3en) complexes were synthesized to systematically regulate their hydration capacity and molecular geometry. The resulting robust three-dimensional hydration network enables a unique size-exclusion mechanism within specialized sub-nanometer polyamide membranes, mitigates the persistent trade-off between osmotic driving force and reverse solute diffusion. Consequently, utilizing the optimized Ni-en draw solute achieved an outstanding pure water flux of 44.9 LMH (120% higher than NaCl) alongside a minimal specific reverse solute flux of 0.09 g L –1 . Furthermore, the system maintained a stable water flux of 26.7 LMH over 36 h of continuous operation when treating a 1000 ppm nickel feed solution. These complexes were efficiently regenerated via a solvent-polarity-controlled phase transition, offering a low-energy recovery alternative. Ultimately, this study provides a proof-of-concept for establishing coordination-regulated complexes as a high-performance draw-solute platform, paving a pathway for hazardous electroplating wastewater valorization.

The construction of an environmentally responsive bactericidal platform enables intelligent and synergistic regulation of bacterial diseases. A pH-responsive pesticide nano delivery system (ZnO@PDA-KAS) was prepared by self-polymerizing a polydopamine (PDA) coating on the surface of ZnO nanospheres synthesized via a hydrothermal method, followed by conjugation with kasugamycin (KAS) in this work. The results showed that ZnO@PDA-KAS exhibited excellent cumulative release under acidic conditions, with a pesticide loading content of 9.4%. The presence of PDA significantly enhanced the adhesion and retention of nanoparticles on rice leaves, whereas fluorescein isothiocyanate-labeled ZnO@PDA exhibited good translocation capacity in rice plants. Moreover, the PDA coating effectively improved the photostability of KAS. In vivo and in vitro antibacterial tests demonstrated that ZnO@PDA-KAS displayed superior antibacterial activity against Xanthomonas oryzae pv. Oryzicola ( Xoc ) due to the synergistic antibacterial effects of Zn 2+ and KAS. This enhanced activity was attributed to the nanoparticles' ability to severely damage bacterial microstructures, enhance rice enzyme activity, and more effectively inhibition of bacterial biofilm formation and induced more severe DNA damage in Xoc cells. Finally, the ZnO@PDA-KAS nanoparticles showed excellent biocompatibility with rice plants and L02 cells. Therefore, the environmentally responsive bactericide ZnO@PDA-KAS provides effective agricultural guidance for efficient and precise release for the management of bacterial plant diseases.

Astragali complanati Semen (ACS) is frequently used as Chinese medicines and functional foods. Complanatoside A (CA), a key bioactive phytochemical isolated from ACS, exhibits broad-spectrum pharmacological properties. This investigation systematically formulated sixteen natural deep eutectic solvent (NADES) systems by combining three hydrogen-bond acceptors with eleven hydrogen-bond donors at varying molar ratios. These NADES formulations were subsequently employed in tandem with ultrasonic-assisted extraction to isolate CA. Optimization studies identified the following parameters as most effective for extraction using the L -proline/levulinic acid-based NADES (molar ratio 1:2): 60℃, 30 min, 40 % water content, liquid-solid ratio 25 mL/g, achieving an extraction yield of 1.57 %. The adsorption and desorption conditions were optimized employing a macroporous resin for the recovery of CA, while the reusability of the NADES solvent was thoroughly evaluated throughout the extraction process. The CA extract exhibited significant tyrosinase and α-glucosidase inhibitory activity. These findings establish ultrasound-assisted NADES extraction as a sustainable methodology for efficient extraction of CA from ACS, providing valuable insights for eco-friendly extraction and pharmacological exploitation of plant-derived bioactives.

Circularly polarized luminescence (CPL) materials are highly sought after for their unique chiroptical properties, but their rational design remains challenging. To address this, a machine learning (ML) platform that intelligently screens deep eutectic solvents (DES) for crafting G-quartet-based gels with tailored CPL is established. An ML classifier trained on experimental data predicts CPL activity with 0.916 accuracy. SHapley Additive exPlanations (SHAP) analysis identifies key DES molecular descriptors, guiding the discovery of novel materials that exhibit a record-high luminescence dissymmetry factor (g lum ) of 0.222 for nucleotide-based systems and achieve chirality inversion via DES modulation. The Sure Independence Screening and Sparsifying Operator (SISSO) algorithm further yields interpretable design formulas. Leveraging the distinct polarization of these gels, we demonstrate a fourth-level anti-counterfeiting strategy, decrypting concealed information via Morse and ASCII codes to enhance information security. This ML-driven methodology accelerates the discovery of high-performance CPL materials and opens new design avenues.

The advancement of Fe-based oxygen evolution reaction (OER) catalysts lags behind their Ni-based counterparts, albeit their good theoretically predicted performance and low cost. Deeply understanding the catalytic mechanism would be necessary to advance the Fe-based catalysts. Currently, Fe-based non-metallic compounds, such as sulfides, phosphides, and selenides, have been widely explored as highly active OER precatalysts because of their tunable electronic structures and relatively high electrical conductivity. Nevertheless, these precatalysts usually undergo surface reconstruction into oxyhydroxides under OER conditions, making the real active phase different from the pristine compound and complicating the structure-performance relationship. Herein, taking the Ni-doped FeS 2 nanosphere catalyst as a platform, we discover a nuanced bidirectional electronic effect within the surface-reconstructed active phase, showcasing the vital roles of both residual FeS 2 and Ni dopants in optimizing catalytic performance. Structural characterizations confirm the successful incorporation of Ni dopants into the pyrite FeS 2 lattice. An amorphous carbon layer is coated on the sulphide nanospheres, which contributes to improving charge transfer efficiency and maintaining structural integrity during electrocatalysis. As a result, the obtained catalyst, typically denoted as Ni 0.2 -FeS 2 @C, achieves markedly enhanced OER activity in the alkaline electrolyte, requiring an overpotential of only 270 mV to reach 10 mA cm −2 , much lower than those of the undoped and uncoated counterparts (FeS 2 @C and FeS 2 ). Moreover, Ni 0.2 -FeS 2 @C exhibits negligible activity decay after 5000 cyclic voltammetry cycles and remains stable during 100 h of constant-potential operation, with Faradaic efficiency for oxygen production close to 100%, demonstrating good catalytic durability and selectivity. Spectroscopic analyses and density functional theory calculations reveal that surface reconstruction during OER leads to the formation of oxyhydroxide as reported elsewhere, but unique electronic interactions, which have not been observed earlier. On the one hand, the residual FeS 2 substrate upshifts the d -band center of the surface oxyhydroxide, strengthening the adsorption behavior of the crucial oxygenated intermediate. On the other hand, Ni dopants induce a downshift of the d -band center, which weakens over-binding inversely. The resulting bidirectional modulation optimizes the electronic structure of active sites and effectively balances the adsorption strength of OER intermediates, thereby reducing the OER energy barrier. Consequently, this work not only provides a viable strategy for the rational design of Fe-based OER catalysts but also deepens the mechanistic understanding of the real active phase of balanced electronic modulation in enhancing electrocatalytic activity. Surface reconstruction generates an oxyhydroxide active layer on Ni-doped FeS 2 for OER, where the FeS 2 substrate and Ni dopants oppositely regulate the d -band center to optimize oxygen-intermediate binding.

The exceptional hardness of diamond dies renders them indispensable in metal wire drawing; however, they remain prone to severe wear and high friction, leading to wire breakage and surface irregularities. Here, we report the achievement of sustained superlubricity on diamond surfaces, characterized by an ultralow friction coefficient of 0.008 and an extremely short running-in period, achieved within 1.6 × 10 6 cycles (equivalent to a sliding distance of 16 km). This remarkable behavior arises from the in situ formation of a graphene oxide-based tribolayer, synergistically driven by metal-catalyzed tribochemical reactions and oligoethylene glycols. Our experiments with several types of friction pair (Ni, Cu and GCr15 steel) and condition (dry friction, drawing oil, diethylene-, triethylene- and tetraethylene-glycol), together with atomistic simulation reveal the mechanism. We further demonstrate the practical viability of this approach using industrial drawing equipment, achieving a 10-91% reduction in drawing force compared to conventional drawing oils.

Background Time-resolved fluorescence immunoassays (TRFIA) have been extensively applied across various fields owing to their low background noise characteristics, particularly in disease diagnosis and prevention. Survival and prognosis of patients with acute myocardial infarction (AMI) are highly dependent on the rapid and accurate detection of myocardial damage. Troponin T (cTnT) is a primary diagnostic biomarker of AMI and is widely used in clinical practice. However, the current bioassays for cTnT detection are complex and time-consuming. Therefore, there is an urgent need for a sensitivity, and rapid diagnostic approach for acute myocardial infarction. Results Herein, we report a novel, sensitive, and specific cTnT detection approach using a unique nanoprobe dissolution-enhanced fluorescence amplification strategy. Eu2O3 nanocrystals, easily dissolvable in an acidic enhancer solution and transformed into many highly luminescent Eu3+ micelles, were utilized as nanoprobes. The released Eu3+ further activates the time-resolved fluorescence system, which prevents autofluorescence interference and blood scattering, allowing for the accurate determination of cTnT levels in clinical serum samples. The demonstrated sensitivity of serum cTnT was high with a sensitivity of 3.86 ng·L−1. In addition, we developed a Eu2O3-based lateral flow immunochromatographic test strip for facile cTnT detection, with the sensitivity of 14.14 ng·L−1 and 6.31 ng·L−1 using smartphone-integrated app and commercial analyzer respectively. Significance This Eu 2 O 3 -nanocrystal-based dissolution-enhanced luminescent bioassay has tremendous potential for ultrasensitive biomarker detection, enabling ultra-trace detection through lanthanide-specific dissolution. Moreover, the surface-functionalized nanocrystals could selectively recognize a variety of analytes, and have excellent photostability with minimal matrix interference, expanding the direction of lanthanide nanoprobes in multifunctional diagnostic and therapeutic areas.

To overcome high regeneration energy in conventional H 2 S capture processes, a novel non-aqueous solvent comprising sterically hindered tertiary-butylaminoethoxyethanol (TBEE) and triethylene glycol (TEG) was developed. At 30 wt% TBEE loading, exceptional H 2 S absorption capacity of 0.982 mol/mol was achieved under 0.6 bar and 293 K. Experimental characterizations combined with theoretical calculations analyses revealed that strong hydrogen-bonding networks between TBEE and TEG significantly enhanced thermal stability. Kinetic studies showed that the rate constants exhibited temperature- and pressure-dependent variations. Thermodynamic analysis using the Reaction Equilibrium Thermodynamic Model with physical absorption (RETM1-P) and van't Hoff equation obtained enthalpy (Δ H ) and entropy (Δ S ) values of −66.76 kJ/mol and −211.85 J/mol·K, respectively. Furthermore, the optimal absorption / desorption temperatures and theoretical desulfurization rate were determined. Moreover, the TBEE/TEG system show excellent recyclability with almost no significant decline in absorption capacity over ten consecutive absorption-desorption cycles, demonstrating its potential for long-term industrial application.

Novel curcumin (Cur) cellular delivery system based on assembly of clover shaped trityl polyethylene glycol (TrPEG) with heat denatured ovalbumin (OVA) through hydrophobic interactions was developed in this study. TrPEGs of different degree polymerization (n = 3, 6, 9) were prepared by the coupling of trityl chloride and PEGs under the optimized condition, and the structures were verified by NMR and MS measurements. The excellent amphiphilic and biocompatible TrPEG-9 demonstrated marvelous selective binding capability with the denatured OVA and stabilization of the assembled particles through the clover shaped head. Introduction of TrPEG-9 (EG) with OVA significantly enhanced encapsulation efficiency (83 %) of Cur and afforded uniform compact nanoparticles (63 nm). Evaluation by Saccharomyces cerevisiae model revealed effectively promoted Cur cellular delivery and significantly reactive oxygen species (ROS) reduction capacity of EG-OVA-Cur, and clathrin-mediated endocytosis and macropinocytosis cellular uptake followed by intracellular vacuolar trafficking. This assembled system has great potential for cellular delivery of nutraceutical and biomedical bioactives.

A novel high-flux polyethersulfone- block -polyethylene glycol (PES- b -PEG) microfiltration (MF) membrane was developed via the vapor-assisted non-solvent-induced phase separation (V-NIPS) method using a 10-s humid air bath. Compared to control PES membranes, the PES- b -PEG membranes exhibit a looser, hourglass-like structure with higher porosity, larger pore diameters, and enhanced water flux and filtration capacity. The onset position of the hourglass-like pores can be finely tuned by adjusting the humid air bath time, enabling significant control over pore diameter and water permeance. Incorporation of PEG into the block copolymer, along with the low viscosity of the casting solution, accelerates water uptake and improves compatibility with water during V-NIPS, promoting efficient vapor-induced phase separation (VIPS) and the formation of a looser, highly permeable structure. With a 10-s air bath, the PES- b -PEG membrane achieves water flux of 45,712 L m −2 h −1 bar −1 , a pore diameter of 0.8 μm, 99.5 % rejection of 1.0 μm polystyrene microspheres, and a filtration capacity of 1,233 L m −2 (at 10 % flux decline). This study highlights the advantages of PES- b -PEG block copolymers for producing high-performance MF membranes with a tailorable hourglass-like architecture via ultrashort humid air exposure.
