[Display omitted] • RuSe 2 nanoparticles could catalyze polysulfide conversion and suppress shuttling. • RuSe 2 absorbs polysulfides weakly but weakens the S-S bonds of polysulfides. • TiO 2 binds polysulfides strongly to be an ideal absorbent. • We electrospun RuSe 2 and TiO 2 as the core/shell nanofibers for Li-S batteries. Lithium‐sulfur (Li‐S) batteries are plagued by shuttling effects and slow kinetics of polysulfides conversion. Although various additives have been widely developed to adsorb polysulfides or catalyze their conversion, molecular-level insights into the correlation between catalytic activity and adsorption strength are still lacking. Therefore, a rational design of Li‐S battery cathodes is limited by the deficiency of a fundamental understanding of the interacting mechanism. Here, we report a RuSe 2 nanocatalyst that has excellent catalytic activity for polysulfide conversion and unfortunately low adsorbing capability as compared to TiO 2. Theoretic and experimental analyses reveal that covalent interaction and electron transfer between RuSe 2 and Li 2 S 4 weakens S–S bonds whereas strong ionic interaction of TiO 2 strengthens only the adsorption of polysulfides. To reconcile their individual drawbacks and make full use of their advantages, we electrospun coaxial nanofibers with RuSe 2 catalytic core and TiO 2 adsorbing shell as the S cathode. The resultant RuSe 2 /TiO 2 nanofibers can rationally maximize their individual functions of RuSe 2 and TiO 2 and realize an ultrahigh capacity of 1402.8 mAh g−1 at 0.1 C and an areal capacity of 7.45 mAh cm−2 under a sulfur loading of 5 mg cm−2. This work demonstrates an integrated approach to improving Li–S battery performance by strengthening catalysis via an increased covalency between active sites and polysulfides and by electrospinning catalysts and adsorbents into coaxial nano-reactors.

• An acoustic metasurface containing coplanar arch-like channels (ALC) is proposed. • The channel with nonuniform cross section can effectively lower the absorption peak frequency. • A unit with multiple different branches is introduced to achieve a wide absorption band. • Varying channel width enables to tailor the absorption band. In this study, a novel compact design for an acoustic metasurface containing coplanar arch-like channels (ALC) is proposed. The ALC is squeezed within a compact disk-shaped volume with a small thickness of 1/94th wavelength for absorbing undesired sound energy at low frequencies in limited-volume circumstances. An impedance-based analytical model is proposed and used for determining the absorption characteristics of arch-like channels with high accuracy. Compared with a uniform cross-section, varied channel widths can effectively lower the operating frequency. Furthermore, using multiple branches with different width arrangements can create a multi-peak absorption profile and effectively broaden the absorption bandwidth. The 3D printing technique is employed to fabricate test samples. The analytical and finite element predictions are verified by comparing those results with experimental measurements. The proposed structure has great potential for applications in noise abatement. [ABSTRACT FROM AUTHOR]

• Novel deep learning architecture for PIH susceptibility prediction. • First introduction of Multi-head self-attention into prediction of PIH susceptibility. • Novel architecture of input data. • Incorporation of all indicators reflecting comprehensive skin conditions. : To construct a neural network model (ATBP) for predicting susceptibility to Post-inflammatory hyperpigmentation (PIH), which is a rapid, objective, and reliable decision-support method before physical and chemical interventions in dermatology clinics for pigment disorders. : A dataset was established based on the VISIA Skin Analysis System detection results of 1953 patients with pigment disorders including 93,477 labeled data under 8 indicators. A novel Post-inflammatory hyperpigmentation susceptibility prediction model incorporating Multi-head self-attention mechanism and Back-propagation neural network is proposed to capture the patterns of skin detection data to predict PIH susceptibility. : The results of comparison experiments indicate that Attentive BP (Back Propagation Neural Network) has a significant superiority in prediction accuracy (0.8604) compared with other machine learning models. The ablation experiments prove that the Multi-head self-attention mechanism substantially improves the accuracy and the stability of prediction. The results of the 10-fold cross-validation experiment prove that ATBP is robust and avoids turbulence in predicting. : Leveraging Multi-head self-attention mechanism and the architecture advantage of BPNN, the proposed model ATBP obtains the robust and efficient prediction performance in predicting PIH susceptibility via processing large-scale and hi-dimension data, i.e., considering comprehensive skin conditions of individual patient. It can be proved from the experimental results that the proposed model is reliable for decision-support work of PIH susceptibility. [ABSTRACT FROM AUTHOR]

A large mode field fiber with bend-resistance is proposed to work at 1550-nm wavelength. After modulation by high refractive index rings introduced in the core and cladding, this fiber can ensure the single-mode operation under a tight bend radius of 10 cm. The finite element method with perfect matching layers (PML) is used to simulate the proposed fiber. Numerical results show that the effective mode area can reach up to 1518.814 μm2 with a 0.004073 dB / m low bending loss of the fundamental mode. The designed all-solid-state fiber has a symmetrical structure and takes no consideration of the bending direction. This fiber has potential applications in high-power lasers. [ABSTRACT FROM AUTHOR]

Triazole fungicides are used to control the disease of cereal crops but may also cause adverse effects on non-target organisms. There is a lack of toxicity data for some triazoles such as fenbuconazole in aquatic organisms. This research was conducted to evaluate the toxicity of fenbuconazole at environmentally relevant concentrations with attention on the mitochondria, antioxidant system, and locomotor activity in zebrafish. Zebrafish were exposed to one concentration of 5, 50, 200 or 500 ng/L fenbuconazole for 96 h. There was no effect on survival nor percentage of fish hatched, but exposure to 200 and 500 ng/L fenbuconazole resulted in malformation and hypoactivity in zebrafish. Oxygen consumption rates (OCR) of embryos were measured to determine if the fungicide impaired mitochondrial respiration. Exposure to 500 ng/L fenbuconazole reduced basal OCR and oligomycin-induced ATP linked respiration in exposed fish. Fenbuconazole reduced mitochondrial membrane potential and reduced the activities of mitochondrial Complex II and III. Transcript levels of both sdhc and cyc1 , each related to Complex II and III, were also altered in expression by fenbuconazole exposure, consistent with mitochondrial dysfunction in embryos. Fenbuconazole activated the antioxidant system, based upon both transcriptional and enzymatic data in zebrafish. Consistent with mitochondrial impairment, molecular docking confirmed a strong binding capacity of the fungicide at the Q i site of Complex III, revealing this complex is susceptible to fenbuconazole. This study reveals potential toxicity pathways related to fenbuconazole exposure in aquatic organisms; such data can improve risk assessments for triazole fungicides. [Display omitted] • Zebrafish exposed to 200 ng/L fenbuconazole induced malformations in larvae. • Oxygen consumption rate of embryos was inhibited in 500 ng/L fenbuconazole. • Locomotor activity of 6 dpf zebrafish was reduced in the visual motor response test with exposure to 500 ng/L fenbuconazole.

Strobilurin fungicides are widely used pesticides in the world. They can have toxic effects not only to target organisms, but also to nontarget organisms. To assess their ecological risk, species sensitivity distributions (SSDs) are required for the development of water quality criteria (WQC). In this paper, the acute toxicity of four methoxyacrylate fungicides were experimentally determined and evaluated at 24, 48, 72 and 96 h for the species of Rana chensinensis and Limnodrilus hoffmeisteri , respectively. Acute and chronic HC 5 (5% hazard concentration) values and WQC values were calculated from SSDs based on the toxicity values determined in this paper and compiled from literature. SSDs revealed that aquatic animals were relatively sensitive species and aquatic plants are insensitive species for the four fungicides. However, different orders of species sensitivity in the acute and chronic toxicity indicated that these four fungicides had different toxic mechanisms or mode of action (MOA) to different species. According to toxicity correlation and principal component analysis (PCA), the kresoxim-methyl toxicity was very close to trifloxystrobin as compared with others due to that they are neutral compounds with very similar physicochemical properties. Quantitative structure-activity relationship (QSAR) revealed that toxicity of strobilurin fungicides were dependent both on chemical hydrophobicity and hydrogen bond basicity. These two molecular descriptors reflect the bio-uptake process and interaction of compounds with target receptors in an organism. WQC values and interspecies correlation are valuable for assessing water quality and understanding toxic mechanisms to different species. [Display omitted] • Acute toxicity of four fungicides have been determined and evaluated at 24, 48, 72 and 96 h. • Water quality criteria of acute and chronic toxicity have been developed for four strobilurin fungicides. • Toxicity of strobilurin fungicides is related with chemical hydrophobicity and hydrogen bonding potential. • The toxicity of four fungicides is not only dependent on the species, but also on the chemical structure. • Kresoxim-methyl toxicity is significantly related to trifloxystrobin toxicity because of their similar structure.

[Display omitted] • Binomial model and structure alert have been developed to identify active cytotoxicity compounds. • Bio-uptake and the interaction through n and π electron pair play important roles in the cytotoxicity. • Bioavailability, ionization and hydrophobicity can affect the chemical cytotoxicity. • Many specifically-acting compounds such as medications and pesticides are active cytotoxicity substances. • Many inactive cytotoxicity substances are inert or less inert compounds. In vitro cytotoxicity assay is an ideal alternative method for the in vivo toxicity in the risk assessment of pollutants in environment. However, modes of action (MOAs) of cytotoxicity have not been investigated for a wide range of compounds. In this paper, binomial and recursive partitioning analysis were carried out between the cytotoxicity and molecular descriptors for 8981 compounds. The results showed that cytotoxicity is strongly related to the chemical hydrophobicity and excess molar refraction, indicating the bio-uptake and chemical-receptor interaction through π and n electron pair play important roles in the cytotoxicity. The decision tree derived from recursive partitioning analysis revealed that the studied compounds could be divided into 25 groups and their structural characteristics could be used as structure alert to identify active and inactive compounds in cytotoxicity. The descriptors used in the decision tree revealed that chemical ionization and bioavailability could affect the cytotoxicity for ionizable and highly hydrophobic compounds. Comparison of MOAs based on Verhaar's classification scheme showed that many inert or less inert compounds were inactive substance, and many reactive or specifically-acting compounds were active substances in the cytotoxicity. In vitro toxicity assay instead of in vivo toxicity assay can be used in the environmental hazard and risk assessment of organic pollutants. The descriptors used in the binomial equation and decision tree reveal that chemical hydrophobicity, ionization and solubility play very important roles for identification of active and inactive compounds. The results obtained in this paper are valuable for understanding the modes of action in cytotoxicity and in vivo - in vitro toxicity relationship. [ABSTRACT FROM AUTHOR]

Imidacloprid is a neonicotinoid that targets sucking pests, such as aphids and the green leaf bug and has been widely applied in wheat fields to control wheat aphids in China. To investigate the involvement of miRNAs in imidacloprid resistance, we sequenced small RNA libraries of Sitobion miscanthi Fabricius, across two different treatments using Illumina short-read sequencing technology. As a result, 265 microRNAs (miRNAs), of which 242 were known and 23 were novel, were identified. Quantitative analysis of miRNA levels showed that 23 miRNAs were significantly up-regulated, and 54 miRNAs were significantly down-regulated in the nymphs of S. miscanthi treated with imidacloprid in comparison with those of the control. Modulation of the abundances of differentially expressed miRNAs, smi-miR-316, smi-miR-1000, and smi-miR-iab-4 by the addition of the corresponding antagomir/inhibitor to the artificial diet significantly changed the susceptibility of S. miscanthi to imidacloprid. Subsequently, the post-transcriptional regulatory mechanism was conducted, smi-miR-278 and smi-miR-316 were confirmed to be participated in the post-transcriptional regulation of nAChRα1A and CYP4CJ6, respectively. The results suggested that miRNAs differentially expressed in response to imidacloprid could play a critical regulatory role in the metabolism of S. miscanthi to imidacloprid. [Display omitted] • 77 differentially expressed miRNAs identified under imidacloprid exposure using Illumina short-read sequencing technology. • Modulation abundances of smi-miR-316, smi-miR-1000 and smi-miR-iab-4 significantly changed the susceptibility to imidacloprid. • CYP4CJ6 and nAChRα1A could be regulated by smi-miR-316 and smi-miR-278, respectively.
