Summary: This study investigated the effect of TiO2 nanoparticle impregnation on the density and dimensional stability of mangium wood. The results showed that TiO2 nanoparticles increased the density, weight percent gain, and bulking effect of the wood. XRD and FTIR analysis confirmed the successful impregnation of TiO2 nanoparticles into the wood, while SEM-EDX analysis revealed that the nanoparticles covered the surface of the wood cells. TiO2-impregnated mangium wood exhibited higher photocatalytic activity, indicating better protection against UV radiation and pollutants.

Summary: Organic air pollutants, including persistent toxic organics and volatile organic compounds (VOC), pose a significant threat to human health. Effective removal of VOC is crucial for environmental protection. Photocatalytic oxidation (PCO) has emerged as a promising technology for VOC removal. In this study, the photocatalytic oxidation method was used to remove benzene and toluene pollutants commonly found in flue gases under UVC irradiation. By adjusting the system parameters, the optimal conditions for simultaneous removal of benzene and toluene were determined to be a temperature of 120 degrees C, humidity of 25%, and 0.5% doping photocatalyst.

Summary: Electrophoretic deposition is an efficient process for manufacturing films or coatings from colloidal suspensions. The deposition of carbon nanotubes on jute fiber surfaces was analyzed using intermittent high voltage electrophoretic deposition. The addition of sodium dodecyl sulfate to the deposition medium resulted in effective and uniform deposition of carbon nanotubes on the jute fiber surface. This deposition enhanced the electrical conductivity and increased the oxygen functional groups on the jute fiber, making it hydrophobic.

Summary: Composite materials based on nanocrystalline anatase TiO2 doped with nitrogen and bismuth tungstate were synthesized using a hydrothermal method. The samples showed different photocatalytic activity in the oxidation of volatile organic compounds under visible light due to the physicochemical characteristics. The Fe/Bi2WO6/TiO2-N composite improved the selectivity of oxidation compared to pristine TiO2-N in the degradation of ethanol vapor, but had an adverse effect in the degradation of benzene vapor.

Summary: The use of low-rank coal as a catalyst support for CO2 methanation can enhance diffusion and adsorption behavior, leading to improved process efficiency. Nickel showed to be the most active metal when supported on low-rank coal, and doping with promoters like Cerium and Magnesium further increased CO2 conversion percentage. The modified LRC-based catalysts exhibited similar or higher activity than commercial metal oxide-supported catalysts, with stable performance over extended periods.

Summary: The basal plane of MoS2 was activated to enhance its hydrogenation activity. The prepared MoS2 catalysts showed a curved shape, and the catalysts pyrolyzed under a N-2 atmosphere had a larger number of S-vacancies. The increase in S-vacancies decreased the Mo-S bond energy and enhanced the catalytic activity.

Summary: Eriocheir sinensis larvae undergo 11 stages, with the most notable change being the folding of the reduced abdomen under the thorax during the transformation from megalopa to juvenile crab. The molecular mechanisms behind this brachyurization process are still unknown. To shed light on this, researchers constructed transcriptome, digital gene expression (DGE), and proteome libraries for Chinese mitten crab larvae in two developmental stages (megalopa and first stage of juvenile crab) and performed RNA sequencing and iTRAQ analysis. They found that 1106 genes and 871 proteins showed differential expression between the two stages. Several important pathways, including biosynthesis of secondary metabolites, metabolic pathways, focal adhesion, and disease pathways, were identified. Muscle contraction, oxidative phosphorylation, calcium signaling, PI3K-Akt, DNA replication pathway, and integrin signaling pathway were also found to play important roles in brachyurization. Additionally, certain components, such as actin, actin-related protein, collagens, filamin-A/B, laminin, integrins, paxillin, and fibronectin, were upregulated in the megalopa stage compared to the first stage of juvenile crab.

Summary: Aquaculture requires effective antibiotic alternatives to control intestinal inflammation, liver inflammation, and metabolic disorder caused by enteritis. Specific metabolites, such as itaconate and fumarate, have shown immunomodulatory effects and are gaining interest as anti-inflammatory medications. In an 8-week feeding experiment on gibel carp, oral administration of 4-octyl itaconate (OI) and dimethyl fumarate (DMF) was found to improve growth performance and increase abundance of beneficial intestinal microbiota. Both OI and DMF alleviated intestinal and hepatopancreas damage caused by enteritis through various mechanisms. Dietary supplementation with 0.1% OI and DMF might be a promising strategy to prevent enteritis and intestinal inflammation-induced hepatopancreas damage in gibel carp.

Summary: The effects of different dietary protein sources were investigated on the reproductive performance of female yellow catfish. It was found that the use of soybean meal as the main protein source improved the reproductive performance by increasing gonadosomatic index, relative fecundity, total egg production, egg diameter, and hatching rate. Soybean meal also promoted the synthesis of sex steroid hormones and vitellogenin, while reducing cholesterol and cortisol levels.

Summary: This study aimed to determine whether and how resveratrol (RES) can alleviate liver injury in lipopolysaccharide (LPS)-induced gibel carp. The results suggested that RES attenuated oxidative stress and inflammation by activating the Nrf2/Keap1 pathway and inhibiting the NF-kappa B pathway. Furthermore, RES cleared damaged mitochondria and enhanced mitochondrial biogenesis to mitigate reactive oxygen species (ROS) accumulation. Overall, RES alleviated LPS-induced oxidative stress and inflammation in gibel carp through mitochondria-related mechanisms.
