Air-processed kesterite solar cells show excellent prospects for commercial application because they are suitable for large-scale production. This study shows how the power conversion efficiency (PCE) of (Cu, Ag) 2 ZnSn(S, Se) 4 solar cells can be improved by adjusting the annealing time during the selenization process at a low temperature of 70 °C. Enhancement of PCE is achieved when the annealing time is 240 s. The primary determinant of enhanced PCE is a reduction in reverse saturation current density (J 0 ) and ideality factor (A). Examination of depth characterization indicated that the decrease in J 0 and A can be ascribed to the inhibition of [2Cu Zn + Sn Zn ] defects cluster, which is mainly accountable for the band tail states, and the suppression of interface recombination .

The self-stacking of MXenes-Ti 3 CN limits the accessibility of nanochannels , reduces the ion diffusion kinetics, and hinders its application in alkali metal ion storage field. This study proposes a point-to-point mortise and tenon joining strategy to fabricate a composite structure of 1,4-phenylenediacetic acid-Ti 3 CN (1,4-PDEA-Ti 3 CN) by grafting rigid and flexible 1,4-phenylenediacetic acid (1,4-PDEA) into the amino-functionalized Ti 3 CN interlayers. The rigid and flexible 1,4-PDEA contributes to a pillar effect in the layered structure of Ti 3 CN, which is benefit to prevent the self-stacking and maintain a stable 2D layered structure. As a result, the interlayer spacing of Ti 3 CN is expanded from 1.20 to 1.46 nm and the Na + diffusion coefficient is improved from 1.16 × 10 −6 to 1.99 × 10 −6 cm 2 s −1 after point-to-point 1,4-PDEA grafting. The 1,4-PDEA-Ti 3 CN achieves a reversible discharge specific capacity of 202.3 mAh g −1 at a current density of 0.1 A g −1 after 770 cycles. Even at a high current density of 5 A g −1 , the 1,4-PDEA-Ti 3 CN still possesses a reversible discharge specific capacity of 137 mAh g −1 and it still maintains the high specific capacity of 256.1 mAh g −1 when the current density comes back to 0.1 A g −1 . This point-to-point mortise and tenon joining strategy provides a novel approach for designing other 2D energy storage materials with long cycle stability and high-rate capability.

The corrosion inhibition behavior and mechanism of disodium 4-dodecyl-2,4′-oxydibenzenesulfonate (DDPBDS) on copper in ammonia water were examined through both experimental methodologies and theoretical computations. The findings indicated that DDPBDS exhibited the capability to concurrently suppress the electrochemical corrosion reactions of copper and was an efficient, durable corrosion inhibitor . At the concentration of 0.1 g/L, DDPBDS demonstrated an impressive corrosion inhibition efficiency of 99.92 % on copper during the initial soaking period, and after soaking for 15 days, its corrosion inhibition efficiency still reached 99.89 %. DDPBDS formed a uniform, dense and hydrophobic protective layer on the copper surface through physicochemical mixed adsorption, which exhibited an adsorption arrangement resembling a skateboard configuration, hindering the copper corrosion .

The synthesis of novel two-dimensional (2D) triangular frustrated compounds are important for providing various platforms to investigate exotic quantum magnetism. Here, we successfully synthesised a series of RE-based magnetic compounds Ba3BiPbREO(BO3)4 (RE = Pr, Nd, Gd, Dy) with a geometrically-perfect 2D triangular lattice directed by triangular BO3 unit. These compounds stabilise 2D layered structures in the hexagonal (P63/mmc) crystal system, where magnetic ions are linked by BO3 to form a perfect triangular frustrated lattice. The magnetisation susceptibility results show that all synthesised compounds Ba3BiPbREO(BO3)4 exhibit dominant antiferromagnetic (AFM) interactions, with no long-range order (LRO) down to 2 K, which is further confirmed by specific heat measurements. Additionally, their thermal stability, attenuated total reflectance Fourier-transform infrared (ATR-FTIR) and Ultraviolet−visible-near-infrared (UV−Vis−NIR) diffuse reflectance spectra are also reported. This work provides a series of RE-based magnetic compounds with a two-dimensional triangular frustrated lattice, offering novel model materials for further investigation on rare-earth-based frustrated magnetism.

Macrocycle-based porous organic polymers (M-POPs) are promising adsorbents for uptake of iodine vapor and adsorption of organic micropollutants (OMPs) from water. Herein, two conjugated triaryl triazine-incorporated, calix[4]pyrrole-based porous organic polymers were prepared by diazocoupling reaction between 4,4′,4′'-(1,3,5-triazine-2,4,6-triyl)trianiline (TTTA) and two configurational isomers of resorcinol-modified calix[4]pyrroles (2α,2β-C4P and 4α-C4P), referred as CP-POP-1 and CP-POP-2, respectively. The obtained CP-POPs were gifted with good porosity, high nitrogen contents and conjugated triaryl triazines, while CP-POP-1 and CP-POP-2 exhibited high iodine vapor uptake at 4.27 g/g and 4.25 g/g, respectively. Charge transfer interaction was the main mechanism for iodine vapor uptake on the CP-POPs. Besides, the CP-POPs displayed preferred adsorption feature to cationic dyes, such as methylene blue (MB), crystal violet (CV) and rhodamine B (RB), while CP-POP-2 showed superior adsorption performance towards cationic dyes. The q m values of MB, CV and RB by CP-POP-2 were as high as 317.46, 373.13 and 471.69 mg/g, respectively. Thermodynamic studies discovered that the adsorption of cationic dyes upon CP-POP-2 was a spontaneous process, while mechanism researches confirmed that electrostatic, hydrophobic and host-guest interactions were involved for adsorption of cationic dyes upon CP-POP-2. In addition, CP-POP-2 could adsorb cationic dyes efficiently from water samples containing complex matrix and exhibited good reusability. The obtained results suggested the bright prospect of the CP-POPs in removal of environmental pollutants. Download: Download high-res image (222KB) Download: Download full-size image

Circulating histones are critical inflammatory mediators that drive hyperinflammation and organ failure in critical illnesses such as sepsis, acute kidney injury, and acute respiratory distress syndrome. Their plasma levels are significantly correlated with disease severity and mortality in such patients. Although both DNA and sulfonic acid-containing macromolecules bind histones via electrostatic interactions, the primary challenge in integrating these antagonists into a unified anti-histone system lies in their mutual water solubility and similar negative charges. Herein, we fabricate novel chitosan/DNA-poly(sodium-4-styrenesulfonate) porous microspheres (C3D1-PSS) by employing a stepwise strategy involving phase inversion and subsequent in situ crosslinking polymerization. With a high-density, negatively charged histone capture network, the C3D1-PSS microspheres exhibit excellent hemocompatibility and achieve a notable histone adsorption ratio of 86.47% within 2 h and 95.52% within 4 h through synergistic electrostatic interactions mediated by phosphate and sulfonate groups in vitro. Furthermore, the C3D1-PSS microspheres significantly mitigate histone-induced thrombocytopenia, platelet activation, hemolysis, cytokine release, and endothelial cell death. In a histone-induced rabbit sepsis model, the C3D1-PSS microspheres efficiently alleviate histone-induced thrombocytopenia, tissue damage, hyperinflammation, and cell apoptosis. Collectively, this work presents a promising adsorbent for extracorporeal removal of histones and holds potential for managing histone-associated critical illnesses.

Silane coupling agent (KH570) was grafted onto Li 2 TiO 3 @GO via its -OH group. • The 12-crown-4 functional group serves as a side arm for the Li + imprinting agent. • H 2 TiO 3 @GO-CR was engineered and exhibited a bifunction Li + capture effect. To enhance lithium-ion adsorption performance, we designed a novel ion-sieve (denoted as H 2 TiO 3 @GO-CR) that synergistically combines the ion-imprinting effect with the intrinsic lithium capture capability of H 2 TiO 3 . This ion-imprinted monomer containing 12-crown-4-ether groups was fabricated through a two-step reaction involving ring-opening and self-condensation. The abundant -OH functional groups on graphene oxide (GO) served as a bridge to graft this monomer onto H 2 TiO 3 . The successful incorporation of the crown ether into the composite was proved by the FT-IR band at 553 cm −1 , and the Raman shift at 154.2 cm −1 . Owing to its unique dual-adsorption structure and functional groups, H 2 TiO 3 @GO-CR exhibited an excellent adsorption capacity of 39.87 mg·g −1 , with XPS analysis verifying an elevated surface hydroxyl (OH) content of 65.68%. In selectivity tests using simulated salt lake brine, the separation factors ( α Li Me) of H 2 TiO 3 @GO-CR for Li + against competing ions (Na + , K + , Ca 2+ , Mg 2+ ) all exceeded 80, demonstrating exceptional selectivity toward Li + . The α Li Mg = 295.0 shows high selectivity in salt lake brine, which is further substantiated by density functional theory (DFT) calculations of adsorption energies. This work brings a novel strategy for developing bifunctional lithium ion-sieves. Download: Download high-res image (265KB) Download: Download full-size image

Validated LC-MS/MS for 4-MEC, M1 and M2 in whole blood • Applied to IV and intragastric pharmacokinetic study • First in vivo PK characterization of 4-MEC and major metabolites • M2 shows prolonged exposure and extended detection window 4-Methyl- N -ethylcathinone (4-MEC) is a novel psychoactive substance and its in vivo exposure characterization remains unknown. In this study, a sensitive and robust liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and fully validated for the simultaneous quantification of 4-MEC and its two major metabolites in rat whole blood. Then it was applied to pharmacokinetic studies of 4-MEC in rats by intravenous and intragastric administration, characterizing the concentration-time profiles of the parent compound and its metabolites. The results revealed distinct exposure patterns between 4-MEC and its metabolites. Notably, M2 ( N -deethylated metabolite) exhibited a prolonged detection window compared with 4-MEC, supporting metabolite-based monitoring strategies and thereby extending its application in forensic toxicology and drug abuse identification.

A mild and efficient method for the solvent-free catalytic nitration of o-xylene (OX) employing silicon sulfonic acid (SSA) as a catalyst and NO 2 as a clean nitrating agent, leads to high selectivity for 4-nitro-o-xylene (4-NOX). Under optimal conditions, a 64.6% selectivity for 4-NOX and a 46.7% conversion of OX were achieved. The results showed that the enhanced OX conversion and target product selectivity were attributed to the synergistic catalysis of the combination of the SSA catalyst and the NO 2 –O 2 system. The characterization results showed that the immobilized SSA, which is not only simple and economical to prepare but also exhibits excellent nitration activity, was effectively synthesized via the chemical bonding method. The highly dispersed sulfonic acid groups were covalently anchored to the surface of the silicon acid (SA), thereby enriching acid sites and stabilizing the catalytic performance. Additionally, a possible reaction mechanism for nitrating OX with NO 2 –O 2 over the SSA catalyst was proposed. Compared with the traditional method, this study promotes the selectivity of the target product while reducing acidic wastewater streams, indicating potential application prospects.

The widespread use of 4-nitrophenol (4-NP) and curcumin, although beneficial across numerous industries, poses potential risks to human health and the environment. Thus, creating a sensitive and straightforward detection strategy is crucial for the rapid monitoring of these pollutants. Herein, a nitrogen-doped carbon dots (N-CDs)-based dual-excitation ratiometric fluorescent probe is developed, capable of detecting 4-NP and curcumin. The N-CDs are prepared from tris (hydroxymethyl) aminomethane (Tris) and phloroglucinol via a facile hydrothermal method, exhibiting a strong cyan fluorescence centered at 497 nm under excitation at 399 nm and 469 nm. In the presence of 4-NP, the fluorescence excited at 399 nm is significantly quenched compared to that excited at 469 nm due to the inner filter effect (IFE) and static quenching, achieving a limit of detection (LOD) of 76 nM within a linear range of 0.076–110 μM. In contrast, curcumin induces nearly complete fluorescence quenching at both excitation wavelengths, resulting from the quenching mechanism of dominant IFE and partial fluorescence resonance energy transfer. This response allows for curcumin detection over a concentration range of 0.081–90 μM with a low LOD of 81 nM. Furthermore, a smartphone-assisted sensing platform is constructed for the visual detection of 4-NP and curcumin in actual samples, achieving LODs as low as 117 nM and 123 nM, respectively. Therefore, this work enhances the capability for multi-analyte monitoring in complex systems and provides a practical and instructive strategy for detecting 4-NP and curcumin.

To achieve efficient separation of emodin and rhein, a double-template Fe₃O₄-imprinted polymer (DT-MIP@Fe₃O₄) was successfully synthesized. The characterization (FT-IR, XRD, TGA, SEM, TEM, VSM) demonstrated that the synthesized DT-MIP@Fe₃O₄ exhibited a core-shell architecture, exhibiting thermal stability up to 270 °C and superparamagnetic characteristics, facilitating separation in 8 s. This material exhibited significant adsorption capacities (31.7823 mg/g and 15.8942 mg/g) and quick adsorption kinetics (equilibrium achieved within 35 min), coupled with the benefits of facile separation, high selectivity, and exceptional reusability. DT-MIP@Fe₃O₄ was utilized as an adsorbent for magnetic solid-phase extraction (MSPE) in conjunction with high-performance liquid chromatography (HPLC) for the simultaneous separation and detection of emodin and rhein in the Chinese herbal medicine SXD. The optimization of parameters influencing MSPE-HPLC was conducted, such as adsorbent dosage, type and volume of desorbent, desorption time, and salt effect. The established method demonstrated exceptional linearity (R² > 0.9999) across the 0.1–100 mg/L, exhibiting high sensitivity and stability. The limits of detection (LOD) and the limits of quantification (LOQ) were established at 0.0092–0.02 mg/L and 0.0307–0.0668 mg/L, respectively. Moreover, the separated fractions demonstrated remarkable hypoglycemic efficacy by DPP-4 inhibition. These findings confirmed the effectiveness of the strategy and indicated that it has considerable prospects in the rapid separation of rhein and emodin from complex Chinese herbal compound, providing a method for the search of natural DPP-4 inhibitors.

In this paper, a SERS/electrochemical dual-channel aptamer biosensor was established for ultrasensitive detection of Pb 2+ . Firstly, the capture probe Fe 3 O 4 @Au@PAMAM@Aptamer and the signal probe AuNs@4-MBA@Au@ssDNA were chemically synthesized step by step. Secondly, the carboxyl graphene oxide (GO) was electrodeposited onto the electrode surface to gain the GO/SPCE. Meanwhile, PAMAM@Au nanomaterials were successfully synthesized and thus prepared the Aptamer/PAMAM@Au/GO/SPCE. During the process, SEM, TEM, FTIR and XPS were applied to characterize the synthesized nanomaterials which confirmed the successful synthesis of the nanomaterials. Finaly, the performance of this biosensor was evaluated in a series of Pb 2+ aqueous solutions by surface enhanced Raman (SERS) and differential pulse voltammetry (DPV). The results showed that the lowest limit of detection (LOD) was 3.16 × 10 −5 nM, and the sample recovery was 99.50–103.67 %. Furthermore, the biosensor demonstrated good specificity, repeatability, and stability. Reliable results were also obtained in actual sample testing. Therefore, it can provide a viable method for trace detection of heavy metal ions.
