Conventional water treatment processes often fail to effectively remove antibacterial drugs, necessitating advanced strategies. This study presents the synthesis of novel floating, visible light-active α-NiMoO4/mpg-C3N4/EP composites for the removal of ciprofloxacin (CFX), a widely used quinolone antibiotic, from water. These composites are easily recoverable, highly stable, and demonstrate excellent reusability. The optimal photocatalyst, NC-101/EP (α-NiMoO4/mpg-C3N4 = 10:1), achieved 96.2 ± 1.1% degradation of CFX at 1.6 g L−1 within 80 min under visible light, significantly outperforming previous benchmarks. This high efficiency is attributed to the formation of interfacial junctions and a built-in electric field, which enhanced charge transfer and hydroxyl radical generation through an S-scheme mechanism. Fluorescence spectroscopy provided precise monitoring of CFX degradation without interference from coexisting intermediates. Density functional theory (DFT) calculations revealed that hydroxyl radicals initiated highly favorable and spontaneous oxidation of CFX, with a reaction rate constant of 6.04 × 109 M−1 s−1. The preferred oxidation pathway followed the sequence: HO-addition > H-abstraction > single electron transfer. Four degradation pathways were identified, with key intermediates confirmed by high-resolution mass spectrometry. The process also significantly reduced CFX toxicity, ensuring minimal environmental impact. These findings position NC-101/EP as a promising photocatalyst for large-scale water treatment applications targeting antibiotic contamination. © 2024 Elsevier Ltd

Multiferroic materials, characterized by the occurrence of two or more ferroic properties, hold potential in future technological applications and also exhibit intriguing phenomena caused by the interplay of multiple orders. One such example is the formation of spin cycloid structures within multiferroic materials, which we investigate in this work by focusing on their magnon excitations and transport based on a general multiferroic Hamiltonian with an antiferromagnetic order. More specifically, we identify the ground state and explore the dynamics of magnon modes, revealing distinct in-plane and out-of-plane modes with anisotropic dispersion relations. The magnon modes include a massless excitation, known as the Goldstone boson, originating from the spontaneous breaking of the translational symmetry by the formation of the cycloid structures. By employing the Boltzmann transport formalism, the magnonic thermal conductivity with spin cycloids and low-temperature anisotropic behaviors is discussed. This work provides pathways to envision the spin-textured multiferroics, which may serve as a fertile ground to look for novel thermal and spin transport with the rich interplay of quasiparticles such as magnons and phonons.

Two-dimensional side-chain plays a crucial role in the construction of efficient non-fused ring electron acceptors (NFREAs). Herein, we introduce an NFREA, PCT-4Cl, featuring a tert-butyl carbazole side-chain, and investigate its optoelectronic properties. Notably, PCT-4Cl exhibits a small singlet-triplet energy gap (ΔEST) of 0.25 eV. Blending PCT-4Cl with the host eC9 or C8C8-4Cl acceptor extends the lifetime of singlet excitons and exciton diffusion length in the blend films. Moreover, the high energy level of the triplet state (ET1) in PCT-4Cl facilitates efficient transfer of triplet excitons to eC9 or C8C8-4Cl. The addition of PCT-4Cl to PM6:eC9 also leads to a longer crystallization time, restraining eC9 aggregation and enhancing crystallinity in the ternary blend films. Consequently, power conversion efficiencies (PCEs) of 18.84% and 15.17% are achieved based on the optimized ternary devices of PM6:eC9:PCT-4Cl and PM6:C8C8-4Cl:PCT-4Cl, respectively, surpassing the performance of PM6:eC9 (17.34%) and PM6:C8C8-4Cl (14.05%). Furthermore, leveraging 2PACz as a hole transporting layer elevates the PCEs of the ternary organic solar cells (OSCs) to 19.25% and 15.53%. These findings underscore the significant role of the tert-butyl carbazole side-chain in enhancing the ET1 of NFREA for efficient charge transfer, as well as its role in modulating the crystallinity, presenting a promising pathway for achieving higher-performance in both binary and ternary OSCs. © 2023, The Authors.

An adaptive response surface methodology based on active subspaces for mixed random and interval uncertainties

Journal of Verification, Validation and Uncertainty Quantification 2019年第2期4卷 021006页

作者： Hu, Xingzhi Duan, Yanhui Wang, Ruili Liang, Xiao Chen, Jiangtao China Aerodynamics Research and Development Center Mianyang621000 China Institute of Applied Physics and Computational Mathematics Beijing100094 China School of Math Shandong University of Science and Technology Qingdao266590 China

The popular use of response surface methodology (RSM) accelerates the solutions of parameter identification and response analysis issues. However, accurate RSM models subject to aleatory and epistemic uncertainties are still challenging to construct, especially for multidimensional inputs, which is widely existed in real-world problems. In this study, an adaptive interval response surface methodology (AIRSM) based on extended active subspaces is proposed for mixed random and interval uncertainties. Based on the idea of subspace dimension reduction, extended active subspaces are given for mixed uncertainties, and interval active variable representation is derived for the construction of AIRSM. A weighted response surface strategy is introduced and tested for predicting the accurate boundary. Moreover, an interval dynamic correlation index is defined, and significance check and cross validation are reformulated in active subspaces to evaluate the AIRSM. The effectiveness of AIRSM is demonstrated on two test examples: three-dimensional nonlinear function and speed reducer design. They both possess a dominant one-dimensional active subspace with small estimation error, and the accuracy of AIRSM is verified by comparing with full-dimensional Monte Carlo simulates, thus providing a potential template for tackling high-dimensional problems involving mixed aleatory and interval uncertainties.

Anthracnose caused by Colletotrichum truncatum (C. truncatum) fungus, a seriously damaged in many soybean growing areas, has almost no effective control strategy. Recently, biostimulants for disease prevention of plants have been considered a feasible solution. In this study, the chitinase-induced effect on soybean plants of various oligochitosan-Zn²⁺ (OC–Zn²⁺) complexes prepared from gamma radiation-degraded oligochitosans with the different molecular weights (Mw) of 2.5, 5.1, and 7.8 kDa was investigated in the first time. The potted soybean plants in a greenhouse were treated with a foliar spray of OC-Zn²⁺ solutions at 50 ppm and inoculated with a disease by a fungal spore suspension spray of C. truncatum to assess the chitinase-elicited effect. The chitinase activity (CA) which described in milliunits per gram (mU/g) of fresh leaves in soybean was determined by the optical density measurement method based on the reducing sugar reaction. The obtained results indicated that the OC-Zn²⁺ complex exhibited a synergistic effect of OC and Zn²⁺. The OC5.1-Zn²⁺ complex prepared from the OC with Mw of 5.1 kDa showed a high chitinase-induced effect with the CA ∼12 mU/g. The OC-Zn²⁺ complexes with effective chitinase inductivity could be feasibly produced on a large scale. Thus, the complexes have been promising to be potentially applied in sustainable agriculture production. © 2022 The Authors

Biosensors are crucial for detecting various analytes relevant to bioanalytical applications. To enhance the specificity and sensitivity of biosensors, bimetallic nanoparticles (BNPs) have been utilized, which demonstrate significant potential for sensing applications owing to their constituent materials’ inherent properties, small size, unique architectural features, and biomimetic behavior. Among BNPs, Au–Ag BNPs are promising for sensing applications owing to their small size, high sensitivity, and distinctive characteristics. Herein, we first briefly present the development of Au–Ag BNPs and discuss the fundamentals. Subsequently, we present the relationship between the synthesis method and structure of Au–Ag BNPs. Furthermore, recent advancements in Au–Ag BNPs are highlighted for their role in enhancing biosensors, particularly for electrode modifiers, signal amplifiers, and recognition materials. Finally, we propose several existing challenges and summarize insights pertaining to the potential development of Au–Ag BNPs for biosensing applications. © 2025 The Authors
