In this study, we aimed to gain insight into the potential of catalytic reduction using copper oxide nanoparticles decorated cellulose acetate as a biosupport (CuO@CA) for the removal of specific pollutants. The prepared catalyst was submitted to a series of spectroscopy techniques for characterization purposes. The results of the catalytic tests on methylene orange (MO) and methylene blue (MB) solutions suggest that the elimination efficiency may be influenced by several factors, including the catalyst dose and the concentration of the pollutant.

Article Synopsis
  • Rodent pests are a big problem for farmers in Morocco, especially those growing crops, and they hurt food security and farmers' incomes.
  • A study surveyed 100 farmers and found that most recognized rodents as a serious threat, with the common types being house mice and roof rats.
  • The study showed that younger and more educated farmers are better at managing rodent issues using eco-friendly methods, while older farmers often rely on chemical poisons.

Dental zirconia ceramics, widely employed in dentistry for their biocompatibility and mechanical properties, face challenges in long-term viability within the oral cavity. This study focuses on analyzing the electrochemical behavior of a commercial dental zirconia ceramic type in acidic environments. Through extensive electrochemical investigations, including Electrochemical Impedance Spectroscopy (EIS) and cyclic polarization resistance (Cpol), corrosion resistance was assessed.

Many plants have been known to be contaminated and accumulate plasticizers from the environment, including water sources, soil, and atmosphere. Plasticizers are used to confer elasticity and flexibility to various fiber and plastic products. Consumption of plasticizers can lead to many adverse effects on human health, including reproductive and developmental toxicity, endocrine disruption, and cancer.

In order to highlight the activities of bioactive compounds present in the stem of sweet cherries, four different cultivars (, , , and ) were collected in Sefrou city in Morocco and were studied. Several assays were performed for this purpose, such as the quantification of phenolic compounds (TPC, TFC, and CTC) and the evaluation of the antioxidant activity using DPPH, ABTS, and FRAP assays. The phenolic profile of each extract was characterized by UHPLC-DAD/MS analysis.
