Improper management of wood impregnation chemicals and treated wood has led to soil contamination at many wood treatment sites, particularly with toxic substances like creosote oil and chromated copper arsenate (CCA). The simultaneous presence of these pollutants complicates the choice of soil remediation technologies, especially if they are to be applied in situ. In this laboratory study, we attempted to immobilise arsenic (As) and simultaneously degrade polycyclic aromatic hydrocarbons (PAHs) (constituents of creosote oil) by applying a modified electrochemical oxidation method.

Detection of viruses, including coronavirus (SARS-CoV-2), via facile, fast, and optical methods is highly important to control pandemics. In this regard, optically-active nanomaterials and nanoparticles (NPs) are a wise choice due to their long-term stability, ease of functionalization, and modifications. In this work, a nanocomposite based on NiFe layered double hydroxide (LDH) and ZIF-67 metal-organic framework (MOF) was designed and synthesized, and decorated on the surface of the melt-blown mask.

Postharvest fruit decay caused by pathogens is an important factor leading to product waste and economic losses, and fruit coating is considered an effective strategy to solve this problem due to its simple operation and effectiveness. In this study, nano modified chitosan film (CSC) was created by mixing chitosan (CS) and copper oxide nanoparticles (CuO NPs) synthesized using abandoned Ficus carica fruit. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectra indicated the formation of intermolecular interactions between CS and CuO NPs in the composite film.
