Article Abstract
Efficient elimination and recovery of phosphorus from agricultural return flows are crucial for effective eutrophication management and phosphorus reuse. In this study, a neutral Fe/Ca oxide co-embedded biochar (FCBC) was synthesized using calcium peroxide and ferrous chloride as precursors for phosphate recovery from agricultural return flows. FCBC possesses a highly intricate pore structure and an abundance of surface-active groups. Fe/Ca oxides were loaded onto the biochar in the form of CaFeO, FeO, and CaCO. FCBC demonstrated a broad pH tolerance range (pH = 6-12) in the aquatic environment. The maximum saturation adsorption capacity was 53.31 mg g. Phosphorus removal is influenced by Ca(PO) generation, intra-particle diffusion, and electrostatic attraction. The produced FCBC showed exceptional phosphorus removal efficiency in the presence of various anions, except for wastewater with high concentrations of SO , CO , HCO , and F (>500 mg L). FCBC can effectively remove phosphorus from agricultural return flows and reduce the risk of the water environment. Returning it to the field can also mitigate the depletion of phosphorus resources, effectively reduce carbon emissions from farmland, improve soil fertility, and realize multiple benefits.

Addressing the issues of slow decomposition and low nutrient release efficiency associated with traditional straw returning, this study innovatively applied ultrasound-assisted centrifugal separation technology to prepare submicron/nano-straw particles and systematically conducted a multi-scale investigation from microscopic to macroscopic levels. The core finding reveals that when the particle size reaches the 1 μm threshold, ultrasonic cavitation vigorously disrupts the straw structure, leading to efficient lignin removal (77.45 %) and a significant reduction in cellulose crystallinity, thereby fundamentally enhancing the degradation rate.

Wastewater surveillance is increasingly an effective public health tool for responding to epidemics and preparing for annual cycles of respiratory illnesses. We measured genetic markers from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), influenza A virus (IAV) and influenza B virus (IBV) in untreated wastewater of a university campus and its local residential community over a four-year period using digital Polymerase Chain Reaction (PCR) methods. These data were then analyzed and compared to clinical case data reported to the state by zip code.

Mango (Mangifera indica), a leading tropical fruit crop, is a prime candidate for intensification through modern orchard-management techniques, including canopy manipulation to improve light interception. This study investigated how leaf-level acclimation to light gradients within the canopy of a high-yield, dwarfing mango cultivar (Calypso™) could be used to examine integrated canopy-scale responses. We quantified foliar morphological, biochemical, and physiological traits across a range of canopy positions using this information to model canopy-scale productivity within digital-twin representations of mango under both conventional (i.

Wheat is the most cultivated crop worldwide, and Australia consistently ranks among the top wheat-exporting countries. Although modern technology has expanded the speed and accuracy of conventional breeding, progress is constrained by limited genetic diversity and linkage drag, with new wheat varieties often taking 8-12 years to reach the market. Biotech methods involving the transformation of foreign DNA into genomes [genetic modification (GM)], or editing of native DNA [genome editing (GEd)], provide novel opportunities to efficiently improve traits alongside conventional breeding.
