Influences of continuous and pulse atrazine exposure on intestinal flora and metabolites of Pelophylax nigromaculatus tadpoles.

Atrazine, a widely used herbicide, has adverse effects on the growth and metabolism of amphibians. Due to the cyclical application use of the pesticide atrazine in agricultural production, atrazine concentrations in water occur in the form of pulses. However, knowledge of the effects of atrazine pulse exposure on the gut microbiota and metabolism of amphibians is limited.

Ferroelectric Nanorods as a Polymer Interface Additive for High-Performance Garnet-Based Solid-State Batteries.

Sandwiching polymer interlayers between the electrode and solid electrolyte is considered promising in solving the interfacial issues arising from solid-solid contact in garnet-based solid-state batteries, but drawbacks including low ionic conductivity, inferior Li transference number, and unsatisfying mechanical property of the polymer hindered the practical application of such strategy. To solve the mentioned shortcomings of the polymer interlayer simultaneously, we introduce the ferroelectric material, BaTiO (BT) nanorods, into the polymer matrix in this work. By taking full advantage of the plasticization effect and intrinsic spontaneous polarization of the introduced ferroelectric, the polymer's ionic conductivity and Li transference number have been significantly enhanced.

nirS and nosZII bacterial denitrifiers as well as fungal denitrifiers are coupled with NO emissions in long-term fertilized soils.

Fertilizer application plays a critical role in soil fertility and crop yield and has been reported to significantly affect soil denitrification. However, the mechanisms by which denitrifying bacteria (nirK, nirS, nosZI, and nosZII) and fungi (nirK and p450nor) affect soil denitrification are poorly understood. Therefore, in this study, we investigated the effect of different fertilization treatments on the abundance, community structure, and function of soil denitrifying microorganisms in an agricultural ecosystem with long-term fertilization using mineral fertilizer or manure and their combination.

Public environmental attention, media coverage, and corporate green innovation: evidence from heavily polluting industries in China.

Against the background of building a multi-environmental co-governance system, it is of great importance to systematically explore how public environmental attention (PEA) affects corporate green innovation (GI). Based on the panel data of Chinese A-share listed enterprises of heavily polluting industries from 2013 to 2020, this paper empirically explores the role of PEA in GI and examines the moderating impacts of media visibility and media favorability. The results indicate that the higher degree of public environmental attention, the more corporate green innovation.

Effects of polysaccharide peptide ameliorating cyclophosphamide-induced immune dysfunctions based on metabolomics analysis.

polysaccharide peptide (GLPP) is one of the most abundant constituents of (), with a wide range of functional activities. The present study investigated the immunomodulatory effects of GLPP in cyclophosphamide (CTX)-induced immunosuppressive mice. The results showed that 100 mg/kg/day of GLPP administration significantly alleviated CTX-induced immune damage by improving immune organ indexes, earlap swelling rate, the index of carbon phagocytosis and clearance value, secretion of cytokines (TNF-α, IFN-γ, and IL-2), and immunoglobulin A(IgA) in the mice.

Simultaneously enhancing the photovoltaic parameters of ternary organic solar cells by incorporating a fused ring electron acceptor.

The ternary strategy has been recognized as an effective method to improve the photovoltaic performance of organic solar cells (OSCs). In ternary OSCs, the complementary or broadened absorption spectrum, optimized morphology, and enhanced photovoltaic performance could be obtained by selecting a third rational component for the host system. In this work, a fused ring electron acceptor named BTMe-C8-2F, which possesses a high-lying lowest unoccupied molecular orbital (LUMO) energy level and a complementary absorption spectrum to PM6:Y6, was introduced to a PM6:Y6 binary system.

Ecotoxicological Differences of Antimony (III) and Antimony (V) on Earthworms (Savingy).

In this study, we assessed the acute and chronic toxic effects of Sb (III) and Sb (V) on (Savingy) () by applying the filter paper contact method, aged soil treatment, and avoidance test experiment. In the acute filter paper contact test, the LC50 values for Sb (III) were 2581 mg/L (24 h), 1427 mg/L (48 h), and 666 mg/L (72 h), which were lower than Sb (V). In the chronic aged soil exposure experiment, when the Sb (III)-contaminated soil was aged 10 d, 30 d, and 60 d after exposure for 7 d, the LC50 value of was 370, 613, and >4800 mg/kg, respectively.

Highly efficient LaMO (M = Co, Fe) perovskites catalyzed Fenton's reaction for degradation of direct blue 86.

Perovskite-structured catalysts LaMO (M = Co, Fe) were successfully synthesized and attempted to catalyze hydrogen peroxide (HO) for the degradation of Direct Blue 86 (DB86), a carcinogenic phthalocyanine dye. The heterogeneous Fenton-like reaction revealed that the oxidative power of the LaCoO-catalyzed HO (LaCoO/HO) process was higher than that of LaFeO/HO. When LaCoO was calcined at 750 °C for 5 h, 100 mg/L of DB86 could be completely degraded within 5 min via LaCoO/HO system under HO 0.

TiO Nanorod-Coated Polyethylene Separator with Well-Balanced Performance for Lithium-Ion Batteries.

The thermal stability of the polyethylene (PE) separator is of utmost importance for the safety of lithium-ion batteries. Although the surface coating of PE separator with oxide nanoparticles can improve thermal stability, some serious problems still exist, such as micropore blockage, easy detaching, and introduction of excessive inert substances, which negatively affects the power density, energy density, and safety performance of the battery. In this paper, TiO nanorods are used to modify the surface of the PE separator, and multiple analytical techniques (e.

A separator modified by barium titanate with macroscopic polarization electric field for high-performance lithium-sulfur batteries.

The detrimental "shuttling effect" of lithium polysulfides and the sluggish kinetics of the sulfur redox reaction in lithium-sulfur batteries (LSBs) impede the practical application. Considering the high polar chemistry facilitates the anchoring of polysulfides, ferroelectric materials have gradually been employed as functionalized separators to suppress the "shuttling effect". Herein, a functional separator coated with BaTiO with a macroscopic polarization electric field (poled-BaTiO) is designed for retarding the problematic shuttle effect and accelerating redox kinetics.

Rice kinesin-related protein STD1 and microtubule-associated protein MAP65-5 cooperatively control microtubule bundling.

STD1 specifically interacts with MAP65-5 in rice and they cooperatively control microtubule bundles in phragmoplast expansion during cell division. Microtubules play critical roles during the cell cycle progression in the plant cell. We previously reported that STEMLESS DWARF 1 (STD1), a kinesin-related protein, was localized specifically to the phragmoplast midzone during telophase to regulate the lateral expansion of phragmoplast in rice (Oryza sativa).
