Dilatancy is commonly defined as the ratio of the rates of plastic volumetric strain to plastic deviatoric strain, denoted as . Owing to the high modulus of elasticity, the elastic volumetric and deviatoric strain rates under shear stress in conventional cohesionless materials are negligible. Therefore, using the ratio of the rates of total volumetric to deviatoric strain () as an approximation is common in studying stress-dilatancy behavior and calibrating dilatancy model parameters.

The sluggish reaction kinetics of the anodic oxygen evolution reaction (OER) and the inadequate catalytic performance of non-noble metal-based electrocatalysts represent substantial barriers to the development of anion exchange membrane water electrolyzer (AEMWE). This study performed the synthesis of a three-dimensional (3D) nanoflower-like electrocatalyst (CFMO) via a simple one-step method. The substitution of Co with Fe in the structure induces a localized oxide path mechanism (LOPM), facilitating direct O-O radical coupling for enhanced O evolution.

Article Synopsis
- The anammox process is gaining attention for its low-carbon and energy-saving benefits, but it still produces greenhouse gases during application.
- Understanding the factors like temperature, salinity, and dissolved oxygen is essential for better managing the production of nitrogen oxides (NO) and methane (CH) in these processes.
- Research findings indicate that higher temperatures significantly boost NO production and nitrogen removal efficiency, while increased salinity reduces NO output and nitrogen removal, highlighting the role of specific microbes in greenhouse gas generation.

Department of Psychology, Northeast Normal University, Changchun, China.
Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children. Previous studies have shown that children with ADHD have impaired processing of emotional stimuli, but it is unclear whether their ability to integrate multimodal emotional stimuli is impaired and at which processing pathway this impairment exists. The present study investigated the ability of children with ADHD to integrate emotional audiovisual stimuli under different emotional conditions, and the effect of audiovisual integration on IOR to reveal the impaired processing pathway of their emotional audiovisual integration.

Investigating the impact of nitrogen doping on the selective adsorption of benzene on activated carbon under aqueous conditions holds significant importance in regulating nitrogen content on activated carbon precisely and enhancing benzene adsorption in the air. This study utilizes quantum chemical simulation to systematically compute the pairwise interactions of pyridine nitrogen, pyrrole nitrogen, graphite nitrogen, and their coexistence on carbon materials, including electrostatic potential, van der Waals potential, and polarity changes. We examine the adsorption of benzene and water on nitrogen-doped carbon materials and calculate the type and proportion of weak interactions in the adsorption process through energy decomposition analysis.

Both the sluggish kinetics of Fe(II) regeneration and usage restriction of HO have severely hindered the scientific progress of the Fenton reaction toward practical applications. Herein, a reduction strategy of activated hydrogen, which was used to simultaneously generate HO and accelerate the regeneration of ferrous in a Fenton-like reaction based on the reduction of activated hydrogen derived from H, was proposed. Two types of composite catalysts, namely, Pd/UiO-66(Zr)-2OH and Pd@UiO-66(Zr)-2OH, were successfully prepared by loading nano-Pd particles onto the outer and inner pores of UiO-66(Zr)-2OH in different loading modes, respectively.

Iron nitrides with the merits of high theoretical capacities, cost-effectiveness, and good electronic/ionic conductivity have been recognized as attractive anode candidates for lithium-ion batteries (LIBs). Carbon compositing, pore engineering, and nanostructure construction have proved to be effective strategies to prepare high-performance metal nitride anodes for LIBs. Herein, we synthesized a series of FeN-embedded and N-doped carbon nanorods (FeN@NCNR) with a hierarchical porous system and controllable topography by metal-catalyzed graphitization-nitridization of the Fe(III)-triazole framework (Fe-MOF) and thermal evaporation of the triblock copolymer F127 template assembled in Fe-MOF via hydrogen bonding interaction, followed by the air oxidation and urea-assisted ammonolysis processes.

Article Synopsis
- Triclosan (TCS) and triclocarban (TCC) are effective sterilizers but raise health concerns due to their environmental toxicity, especially in the context of immunotoxic effects.
- A study using zebrafish revealed that both chemicals resulted in low hatching rates and high mortality, with TCC causing more severe developmental issues than TCS.
- TCS increased the proliferation of innate immune cells but reduced mature T cells, while TCC inhibited both types of immune cell differentiation; both pollutants altered pro-inflammatory cytokine levels correlating with toxicity.

In a photocatalysis process, quick charge recombination induced by small electron polarons in a photocatalyst and sluggish kinetics of hole transfer at the solid-liquid interface have greatly limited photocatalytic efficiency. Herein, we demonstrate hydrated transition metal ions as mediators that can simultaneously accelerate small electron polaron dissociation (via metal ion reduction) and hole transfer (through high-valence metal production) at the solid-liquid interface for improved photocatalytic pollutant degradation. Fe, by virtue of its excellent redox ability as a homogeneous mediator, enables the BiVO photocatalyst to achieve drastically increased photocatalytic degradation performance, up to 684 times that without Fe.
