“…For organic compounds such as plastic resins, fragmentation is shown to be one of the ways that facilitate subsequent reactions forming stable carbocations to the detriment of the ionization potential of the compounds. 24 These findings show us that the free energy is in inorganic compounds or high spin, somatized to their formation energetic defects, the electronic proximity and consequently attraction and repulsion of electrons, as well as in organic compounds the stability of the carbocation formed in the synthesis reaction of the compound facilitates the increase of energy in the free volume of plastic resins.…”

The advent of plastic to the social situation has suppressed a series of demands from both the industry and the population, due to cost, durability and disposal. Because they can be rigid, malleable, opaque, translucent, easy or difficult to melt by the action of fire, some make them capable of serving as raw material for various products on the market, including those widely used in the food industry. In view of the above, the present study aims at a bibliographical review on the topic of microplastics, where the search will be to verify the primary and secondary steps necessary for the formation of the compound, its direct and indirect influence on food production, the physical-chemical processes through which compounds are obtained and the presence or absence of regulation regarding this environmental liability. The present study aims to analyze as a basis the search for knowledge of the primary and secondary formation of microplastics. Subsequently, together with its main objective, this study aims to search for the physico-chemical and thermodynamic phenomena involved in the process of formation and obtaining of microplastics, the polluting potential and, like all waste, its implications for human health. A study horizon was established covering the years 2015 to 2023, where 3,750 articles were found and after applying open access filters, duplication of publication, words present only in the abstract and not in the text, 49 articles remained that are the object of this study. The direct implications of microplastic pollution are already a relevant reason for discussion and subsequent regulation by managers, researchers, international organizations and society in general. Public health problems that can transform into microplastics, containment and adsorption mechanisms of these compounds in living organisms, are points to be pursued by academia as a whole. Contamination by these compounds was found in bottled mineral water, human milk, processed foods, seafood, showing the extent of contamination of this material.

“…Kumar was successful in attaining huge rst-order hyperpolarizability of 923.93 × 10 − 30 esu [18]. Novel V-shaped donor-π-acceptor chromophores 4-(1-Piperidinyl)benzaldehyde and 4-ethoxybenzaldehyde were designed and synthesized by Y. C. Feng et.al [19]. Further, the synthesized solutions were employed for investigating the possible two-photon absorption and also used for imaging purposes in living cells [19].…”

The present study accounts for the quantum chemical and nonlinear optical properties of the combination of para-aminobenzoic acid and 7-diethylamino 4-methyl coumarin. Three different complexes were designed, surface interaction (adsorption) and two by connecting both molecules with πbridge benzene and biphenyl. The amino and carboxyl groups were observed to behave as strong donor and acceptor sites in all the complexes. The band gap of the adsorbed complex was found more suitable. The absorption wavelength and intensity both were seen to increase with the increase in the number of benzene rings in the π-bridge. The chemical reactivity was established by the global reactivity descriptors. The values of rst and second-order hyperpolarizability suggest the improved nonlinear optical responses of the introduced complexes. Additionally, the negative value of second-order hyperpolarizability suggests the possibility of the occurrence of reverse saturable absorption in these combinations. The reported work gives theoretical insights into the nonlinear optical properties of the combination of para-aminobenzoic acid and 7-diethylamino 4-methyl coumarin.
