Removal of typical pollutant ciprofloxacin using iron-nitrogen co-doped modified corncob in the presence of hydrogen peroxide.

Iron-nitrogen co-doped modified corncob (Fe-N-BC) was synthesized using a hydrothermal and calcination method. The material shows excellent oxidation performance and environmental friendliness. When the dosage of Fe-N-BC was 0.

Metagenomic analysis insights into the influence of 3,4-dimethylpyrazole phosphate application on nitrous oxide mitigation efficiency across different climate zones in Eastern China.

Excessive nitrogen (N) fertilization in agroecological systems increases nitrous oxide (NO) emissions. 3,4-dimethylpyrazole phosphate (DMPP) is used to mitigate NO losses. The influence of DMPP efficiency on NO mitigation was clearly affected by spatiotemporal heterogeneity.

Organic amendments alter microbiota assembly to stimulate soil metabolism for improving soil quality in wheat-maize rotation system.

Straw retention (SR) and organic fertilizer (OF) application contribute to improve soil quality, but it is unclear how the soil microbial assemblage under organic amendments mediate soil biochemical metabolism pathways to perform it. This study collected soil samples from wheat field under different application of fertilizer (chemical fertilizer, as control; SR, and OF) in North China Plain, and systematically investigated the interlinkages among microbe assemblages, metabolites, and physicochemical properties. Results showed that the soil organic carbon (SOC) and permanganate oxidizable organic carbon (LOC) in soil samples followed the trend as OF > SR > control, and the activity of C-acquiring enzymes presented significantly positive correlation with SOC and LOC.

RSM, ANN-GA and ANN-PSO modeling of SDBS removal from greywater in rural areas FeO-coated volcanic rocks.

Decontamination and reuse of greywater in rural areas has attracted increasing attention. Typical contaminants in grey water are SDBS, which has a stubborn molecular structure. In this study, FeO-coated volcanic rocks (FeO-VR) prepared from FeCl solution by a heating evaporation method can reach 95% removal of SDBS, which is 80% higher than before.

Adsorption and Fenton-like Degradation of Ciprofloxacin Using Corncob Biochar-Based Magnetic Iron-Copper Bimetallic Nanomaterial in Aqueous Solutions.

An economical corncob biochar-based magnetic iron-copper bimetallic nanomaterial (marked as MBC) was successfully synthesized and optimized through a co-precipitation and pyrolysis method. It was successfully used to activate HO to remove ciprofloxacin (CIP) from aqueous solutions. This material had high catalytic activity and structural stability.

Fertilizer stabilizers reduce nitrous oxide emissions from agricultural soil by targeting microbial nitrogen transformations.

Nitrous oxide (NO) is a pollutant released from agriculture soils following N fertilizer application. N stabilizers, such as N-(n-butyl) thiophosphoric triamide (NBPT) and 3,4-dimethylpyrazole phosphate (DMPP) could mitigate these NO emissions when applied with fertilizer. Here, field experiments were conducted to investigate the microbial mechanisms by which NBPT and DMPP mitigate NO emissions following urea application.

Cysteine Dioxygenase Regulates the Epithelial Morphogenesis of Mammary Gland via Cysteine Sulfinic Acid.

Epithelial morphogenesis is a common feature in various organs and contributes to functional formation. However, the molecular mechanisms behind epithelial morphogenesis remain largely unknown. Mammary gland is an excellent model system to investigate the molecular mechanisms of epithelial morphogenesis.
