Summary: Passivated manganese oxide-coated sand can efficiently oxidize bisphenol A after treatment with oxidants, acid, or methanol, with hypochlorous acid and hypobromous acid being the most effective regenerants. Regeneration with potassium permanganate resulted in lower Mn(III) abundance and a structure less reactive towards bisphenol A.

Summary: The study characterized the bacterial communities associated with different cultivation systems of the microalga Tetradesmus obliquus. Metagenomic analysis was performed on biomass samples collected from sequential cultivation in three different systems. The results identified 72 OTUs, with Brevundimonas and Porphyrobacter being the most abundant taxa. Different cultivation systems showed an increase in taxa richness and diversity in the super-intensive and intensive systems.

Summary: The study investigated the sorption enhanced steam reforming (SESR) of toluene using a Ni/perovskite catalyst and CaO sorbent, achieving high hydrogen purity at an appropriate temperature. Regeneration and characterization of the catalyst showed stable performance and compatibility in the SESR process for high-purity hydrogen production.

Summary: This study investigated the sorption of aqueous Mn(II) and Co(II) onto hexagonal birnessite under anoxic conditions. The results showed that the co-sorption of Mn(II) and Co(II) led to reduced sorption rates and extent. The presence of Mn(II) affected the transformation of birnessite and the speciation of Co(II). These findings indicate the significant impact of aqueous Mn(II) on the reactivity and solubility of Co(II) in geochemical environments.

Summary: The presence of phosphate or silicate significantly decreases the rate and extent of reductive transformation of layered manganese oxides, likely due to the interference of oxyanions with electron transfer and structural rearrangements. Oxyanions also reduce the crystallinity and particle sizes of the transformation products, preventing further particle growth. This study enhances our understanding of how solution chemistry controls the redox-driven transformation of Mn oxides.

Summary: There is a growing interest in using plant waste for environmental protection materials. This study focused on preparing silica powders from various biomass materials, such as horsetail, common reed, wheat, and rye straws. The powders were obtained through a simple and low-cost procedure, which involved leaching the biomass materials in a boiling HCl solution, incinerating the samples, and removing the organic components. The resulting biosilica powders showed high purity and mainly consisted of SiO2. The horsetail-derived biosilica exhibited good adsorption capacity for removing Cr(VI) ions from water, particularly after surface modification with a surfactant. The biosilica also demonstrated low cytotoxicity to human endothelial cells, indicating its potential for safe use in environmental remediation.

Summary: This study investigates the crucial roles of interlayer of montmorillonite, vermiculite, and illite in Ni(II) sorption through batch experiments, X-ray diffraction (XRD), and surface complexation model. The Ni(II) sorption followed the order of montmorillonite ≈ vermiculite > illite in NaCl solution, but decreased significantly in CsCl solution. XRD patterns and release experiments confirmed the partial collapse of montmorillonite and vermiculite interlayers after equilibration with Cs+ and Na+. The ion exchange and surface complexes were identified as the primary sorption mechanisms on clay minerals.

Summary: The presence of gallic acid (GA) was found to significantly promote the transformation of SMX by birnessite, especially at pH 6.0 compared to pH 4.0. The promotive effect was attributed to the addition reactions between SMX and GA quinones, as well as condensation reactions between -COOH of quinones and -NH2 of SMX or its transformation products.

Summary: This study investigated the differences in skin bacterial assemblages of salamanders belonging to three genera in the Plethodontidae family. The results showed that both host-specific factors and the environment influence the structure of skin bacterial assemblages. The study also found that the influence of host genus and species was more significant than sampling site. Furthermore, the relationship between skin bacterial assemblages and climatic variables varied among the different host genera.

Summary: The plant microbiota in paddy soil can influence plant health and fitness by promoting methylmercury (MeHg) production. However, the effect of rice rhizosphere assemblages on MeHg production remains unclear. This study used network analyses of microbial diversity to investigate the bacterial networks in bulk soil, rhizosphere, and roots during rice development at different Hg gradients. The results showed that Hg gradients significantly affected the niche-sharing of taxa related to MeHg/THg, while plant development had minimal effect. The complexity and connectivity of root microbial networks increased with an Hg concentration of 30 mg kg-1 in the soil.

Summary: Biomass-based humic acid (BHA), rich in functional groups, was obtained from waste rice straw using a one-step hydrothermal process. BHA was then co-precipitated with magnetic nanoparticles (MNP) to produce a magnetic composite (BHA@MNP) for efficient adsorption of heavy metal ions (Cd2+, Pb2+, and Ni2+) from water bodies. BHA@MNP exhibited a maximum adsorption capacity (Q(m)) of 290.81, 374.99, and 296.85 mg g(-1) for Cd2+, Pb2+, and Ni2+, respectively. The addition of BHA improved the dispersion and oxidation resistance of MNPs, providing more adsorption sites and increasing the specific surface area. The adsorption mechanism of Cd2+, Pb2+, and Ni2+ onto BHA@MNP was primarily chemosorption and was a spontaneous endothermic process. The prepared BHA@MNP can be easily separated, recycled, and regenerated, making it a promising green adsorbent for water pollutant removal.

Summary: The extraction of uranium from seawater using various biomaterials was studied. It was found that certain fruit and vegetable materials showed good uranium sorption ability, with citrus peel and potato skin exhibiting the highest sorption. The presence of polyphenols was found to enhance sorption, and a positive correlation was observed between polyphenol concentration and sorption efficiency.

Summary: Periphytic algal assemblages in the regulated River Sindh of Kashmir Himalaya were studied to understand their ecology in a regulated river ecosystem. Seasonal sampling from 2017 to 2019 revealed distinct groups based on sites and seasons. Geo-physical factors accounted for most variations, while the scraper community played a minor role. This study provides scientific insights related to the ecology of a regulated Himalayan river.
