Polystyrene nanoplastic mass spectra suffered interference from silver cluster ions. Nonpolar matrices enhanced the polystyrene nanoplastic mass spectral quality.
Recent advances in graphene research have enabled the utilization of its nanocomposites for numerous energy-based and environmental applications. Recently, the advancement in graphene-based polymer nanocomposites has received much attention with special emphasis on synthesis and application. Graphene-based nanocomposites show astonishing electrical, mechanical, chemical, and thermal characteristics. Graphene nanocomposites (GNCs) are synthesized using a variety of methods, including covalent and non-covalent methods, a chemical-based deposition approach, hydrothermal growth, electrophoresis deposition, and physical deposition. Chemical methods are the most viable route for producing graphene in small quantities at low temperatures. The technique can also produce graphene films on a variety of substrate materials. The use of artificial intelligence (AI) for the synthesis of AI-created nanoparticles has recently received a lot of attention. These nanocomposite materials have excellent applications in the environmental, energy, and agricultural sectors. Due to high carrier mobility, graphene-based materials enhance the photocatalytic performance of semiconductor materials. Similarly, these materials have high potential for pollutant removal, especially heavy metals, due to their high surface area. This article highlights the synthesis of graphene-based nanocomposites with special reference to harnessing the power of modern AI tools to better understand GNC material properties and the way this knowledge can be used for its better applications in the development of a sustainable future.
Topological Insulators (TIs) have become new potential materials because of their super surface conduction and bulk insulation. Their technological importance motivated us to explore the topological nature of SrPtS and BaPtS Heusler alloys using full potential linearized augmented plane wave (FP-LAPW) method as implemented in Wien2k. Structural stability is checked using three different Wyckoff positions and further investigations were carried out to find the dynamic stability with phonon dispersion curves. The electronic band structure of both materials show metallic nature when generalized gradient approximation with Perdew-Burke-Ernzerhof (GGA+PBE) exchange and correlation functional is used but there appears a band gap when spin orbit coupling (SOC) was implemented. The band inversion strength has also been tested by applying the external pressure. Further, both alloys have been found mechanically stable and ductile in nature by determining the elastic parameters. Thermal and electrical conductances were also determined and discussed. The findings show that these materials being topological insulators are suitable for technological applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
