the pollution of water environments is a challenging issue especially in developing countries. contamination of drinking water with heavy metals has been reported in many parts of the world. arsenic, chromium and lead are dangerous heavy metals and also common contaminants of drinking water. in this study, the capacity and performance of the surfactant-modified sabzevar natural nanozeolite (sms...

Topological characterization of 3D molecular structures is an emerging study area in theoretical and computational chemistry. These structural descriptors are used a variety domains, including chemical graph theory, drug delivery, nanomaterial characterization. Quantitative can be to characterize the physical properties given compound. indices graphs numerical quantities that allow us collect i...

Natural zeolites are commonly described as macromolecular sieves. Zeolite networks very trendy chemical due to their low-cost implementation. Sodalite network is one of the most studied types zeolite networks. It helps in removal greenhouse gases. To study this rich network, we use an authentic mathematical tool known M-polynomials topological index and show some physical properties numerical f...
