Microplastics (MPs) are emerging contaminants that act as vectors for organic pollutants such as polyaromatic hydrocarbons (PAHs), altering their fate, bioavailability and toxicity in ecosystems. The present review emphasizes on the incidence of these complexes across marine, freshwater and terrestrial ecosystems. Their adsorption-desorption behavior is governed by MP properties (eg size, shape, polymer types), PAH properties (eg hydrophobicity, molecular weight) and environmental factors (eg pH, temperature). The reported toxicological effects of PAH-MP interactions on living systems based on both enhanced and mitigated PAH bioavailability are presented, backed by recent literature reports. A thorough bibliometric analysis of 300 + studies reveals growth in this field but also highlights critical gaps in chronic exposure studies, multiple pollutant toxicity and standardization of test protocols. Hence, this review provides valuable insights into interactions between PAHs and MPs shedding light on various aspects facilitating further research in this area.

Mechanochemical reduction of β-diketiminate (BDI) barium iodide precursors with K/KI resulted in the first barium inverse sandwich complexes containing the benzene dianion in yields of up to 54%. This most challenging isolation of highly reactive (BDI)Ba-(CH)-Ba(BDI) complexes, completes the family of heavier benzene inverse sandwich complexes and allows for a comparison of trends in the series from Mg, Ca, Sr to Ba. Syntheses, stabilities, structures, electronic states and reactivities of the full range are compared.

Human activity has led to the increment of diverse pollutants. Plastics have great practical value since they are present in everyday products. However, not only plastics have gained importance, but their plasticizers such as bisphenol A (BPA), phthalates and other chemicals such as the polyaromatic hydrocarbon compounds (PAHs) have described to impact in human and animal health because of its chronic exposure and that they are endocrine disruptors (EDs).

Electricity is an essential and critical component for contemporary life. An energy crisis is emerging worldwide because electricity demand and consumption exceeds production capacity. Lebanon a country that has suffered from consecutive wars in addition to a crippling financial crisis lacks the capacity to provide 24-h electricity supply.

FeNiMn invar alloy was produced via the polyol process, employing a polyvinyl alcohol (PVA) solution in varying weight ratios (50% and 66% PVA), and carbonized at different temperatures in argon (Ar) atmosphere to create a magnetic core-shell structure of FeNiMn@C. The structural, morphological, and magnetic characteristics of the prepared material were analyzed using X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Brunauer-Emmett-Teller (BET) method, Fourier-transform infrared spectroscopy (FTIR), and vibrating sample magnetometry (VSM). The carbonization process applied to these samples enhances their suitability for the adsorption of weakly polar or nonpolar organic molecules.

Multiple epidemiological studies link cardiac dysfunction with increased levels of air pollution. While cellular mechanisms underlying such dysfunction are yet to be fully elucidated, a proposed mediator of this effect is phenanthrene, a 3-ringed polycyclic aromatic hydrocarbon (PAH). Here, we used ventricular myocytes freshly isolated from healthy female sheep (Ovis aries) to study the impact of acute phenanthrene exposure on cardiac electrophysiology and intracellular Ca cycling in a large mammalian model.
