A Critical Review of Deep Oxidation of Gaseous Volatile Organic Compounds via Aqueous Advanced Oxidation Processes.

Volatile organic compounds (VOCs) are considered to be the most recalcitrant gaseous pollutants due to their high toxicity, diversity, complexity, and stability. Gas-solid catalytic oxidation methods have been intensively studied for VOC treatment while being greatly hampered by energy consumption, catalyst deactivation, and byproduct formation. Recently, aqueous advanced oxidation processes (AOPs) have attracted increasing interest for the deep oxidation of VOCs at room temperature, owing to the generation of abundant reactive oxygen species (ROS).

Metal-organic framework-based membranes for ion separation/selection from salt lake brines and seawater.

Nanofiltration (NF) technologies have evolved into a stage ready for industrial commercialization. NF membranes with unique separation characteristics are widely used for ion selection in water environments. Although many materials have been synthesized and functionalized for specific ion separation, the permeability-selectivity trade-off is still a major challenge.

Enhancing YOLO for occluded vehicle detection with grouped orthogonal attention and dense object repulsion.

In real-life complex traffic environments, vehicles are often occluded by extraneous background objects and other vehicles, leading to severe degradation of object detector performance. To address this issue, we propose a method named YOLO-OVD (YOLO for occluded vehicle detection) and a dataset for effectively handling vehicle occlusion in various scenarios. To highlight the model attention in unobstructed region of vehicles, we design a novel grouped orthogonal attention (GOA) module to achieve maximum information extraction between channels.

Efficient Ozone Elimination Over MnO via Double Moisture-Resistance Protection of Active Carbon and CeO.

The widespread ozone (O) pollution is extremely hazardous to human health and ecosystems. Catalytic decomposition into O is the most promising method to eliminate ambient O, while the fast deactivation of catalysts under humid conditions remains the primary challenge for their application. Herein, we elaborately developed a splendidly active and stable Mn-based catalyst with double hydrophobic protection of active carbon (AC) and CeO (CeMn@AC), which possessed abundant interfacial oxygen vacancies and excellent desorption of peroxide intermediates (O).

Construction of hollow sphere MnO with abundant oxygen vacancy for accelerating VOCs degradation: Investigation through operando spectroscopycombined with on-line mass spectrometry.

To clarify the key role of oxygen vacancy defects on enhancing the oxidative activity of the catalysts, metal-organic frameworks (MOFs) derived MnO catalysts with different morphologies and oxygen vacancy defects were successfully prepared using a facile in-situ self-assembly strategy with different alkali moderators. The obtained morphologies included three-dimensional (3D) triangular cone stacked MnO hollow sphere (MnO-H) and 3D nanoparticle stacked MnO nanosphere (MnO-N). Compared to MnO-N, MnO-H exhibited higher activity for the oxidation of toluene (T = 226 °C).

Efficient Catalytic Elimination of Toxic Volatile Organic Compounds via Advanced Oxidation Process Wet Scrubbing with Bifunctional Cobalt Sulfide/Activated Carbon Catalysts.

Advanced oxidation process (AOP) wet scrubber is a powerful and clean technology for organic pollutant treatment but still presents great challenges in removing the highly toxic and hydrophobic volatile organic compounds (VOCs). Herein, we elaborately designed a bifunctional cobalt sulfide (CoS)/activated carbon (AC) catalyst to activate peroxymonosulfate (PMS) for efficient toxic VOC removal in an AOP wet scrubber. By combining the excellent VOC adsorption capacity of AC with the highly efficient PMS activation activity of CoS, CoS/AC can rapidly capture VOCs from the gas phase to proceed with the SO and HO radical-induced oxidation reaction.

Key role of •O in promoting deep degradation of VOCs in VUV-based process.

VUV photolysis presents a simple process for VOCs degradation, while the poor mineralization rate and extensive by-products greatly limit its application. In this study, the contribution and synergy between •OH and •O to toluene degradation in the VUV-based process were comprehensively investigated by controlling water and oxygen in the gas flow. It was found that •OH promoted the initial degradation of toluene and macromolecular intermediates, while •O dominated toluene mineralization by boosting the formation of small molecules and CO.

Tunable Interfacial Electronic Pd-Si Interaction Boosts Catalysis via Accelerating O and HO Activation.

Engineering the interfacial structure between noble metals and oxides, particularly on the surface of non-reducible oxides, is a challenging yet promising approach to enhancing the performance of heterogeneous catalysts. The interface site can alter the electronic and -band structure of the metal sites, facilitating the transition of energy levels between the reacting molecules and promoting the reaction to proceed in a favorable direction. Herein, we created an active Pd-Si interface with tunable electronic metal-support interaction (EMSI) by growing a thin permeable silica layer on a non-reducible oxide ZSM-5 surface (termed Pd@SiO/ZSM-5).

Changes in gonadal function at different stages of chronic restraint stress-induced depression animals.

The aim of this study was to determine the time-dependent changes in adolescent male gonadal function due to chronic restraint stress (CRS)-induced depression in a rat model and to elucidate the underlying mechanism. CRS was established in adolescence male Wistar rats by placing the animals in a cylinder for 3 h every day for 28 days, during which time the general behavior and serum hormonal levels were routinely monitored. The CRS model rats showed anxiety-like behavior in the open field test (OFT) and sucrose consumption test, and their body weights also decreased significantly on the 14th, 21st and 28th days.
