An appropriate artificial intelligence technique for plastic materials recycling using bipolar dual hesitant fuzzy set.

Plastic recycling has become more important than ever as the globe struggles with growing environmental issues. This research explores the significant environmental impact of recycling plastic and its growing relevance. The pervasive material known as plastic presents a complex risk to both human health and ecosystems in contemporary life.

Synthesis, growth, structure and spectroscopic characterization of a new organic nonlinear optical hydrogen bonding complex crystal: 3-carboxyl anilinium p-toluene sulfonate.

A new organic nonlinear optical hydrogen bonding complex salt of 3-carboxyl anilinium p-toluene sulfonate has been synthesized and highly transparent good quality single crystals of it were successfully grown employing slow solvent evaporation solution growth technique at ambient temperature. The (1)H and (13)C NMR spectra were recorded to establish the molecular structure. The single crystal XRD analysis carried out reveals that the title salt crystallizes in monoclinic crystal system with non-centrosymmetric P2₁ space group.
