As the world's leading producer of pigs, China is now experiencing large-scale pollution derived from agricultural usage of untreated pig manure, where passivation of metal toxicity in pig manure is a major challenge. Here, the effect of green synthesized iron nanoparticle (G-nFe) addition on copper (Cu) transformations during thermophilic aerobic composting of pig manure was investigated. The results revealed that following addition of G-nFe passivation of active Cu forms, including exchangeable (EXC-Cu), carbonate-bound (CARCu), and iron and manganese oxide-bound (IMOCu) Cu increased by 66.

Article Synopsis
  • The study investigates how genetic inversions contribute to parallel evolution in different dune ecotypes of the sunflower species Helianthus petiolaris.
  • Researchers found that inversions help preserve beneficial alleles and enhance adaptive responses, leading to similar traits in separate populations exposed to similar environmental pressures.
  • Their analyses revealed that inversions not only contained more shared genetic traits than expected, but also supported the idea that these genetic structures play a key role in driving parallel adaptation among the dune ecotypes.

Article Synopsis
  • Measurement-based care (MBC) enhances evidence-based practices (EBPs) by providing personalized feedback reports to clients and clinicians, particularly for young people with early psychosis.
  • A study evaluated these feedback reports at five specialty care programs, comparing outcomes for clients who received reports versus those who did not over their first six months of treatment.
  • Results indicated improvements in decision-making and treatment engagement among clients receiving feedback, with they participating more in supportive services, although overall statistical significance was not achieved.

Interfacial solar evaporation-based seawater desalination is regarded as one of the most promising strategies to alleviate freshwater scarcity. However, the solar evaporation rate of real seawater is significantly constricted by the ubiquitous salts present in seawater. In addition to the common issue of salt accumulation on the evaporation surface during solar evaporation, strong hydration between salt ions and water molecules leads to a lower evaporation rate for real seawater compared to pure water.

Iron nanoparticles synthesized using Euphorbia cochinchinensis leaf extracts (Ec-FeNPs) showed high selectivity for rare earth elements (REEs) recovery from mining wastewater. REEs recovery efficiencies were > 90 %, with distribution coefficients ranging from 2483.9 to 37500 mL/g, which were consistently much higher than non-REEs (15.
