Abstract: Background: The Seshachalam hill ranges of Eastern Ghats are known for their endemic flora. There were seven endemic species situated here in which present plant species Terminalia pallida (T. pallida) is one, this Endemic semi-tree species has a great medicinal value; at the same time, due to the presence of different types of secondary metabolites, they easily form nanoparticles and exhibit certain high-quality characteristics after being combined with noble metals like silver. Objective: These Silver Nanoparticles (SNPs) display peculiar characteristics in their nano level which shows more effectiveness compared to their raw extracts, with negligible side effects. The present work shows in vitro antioxidant (DPPH radical scavenging assay) and anti-inflammatory (inhibition of albumin denaturation) applications of SNPs synthesized from leaf, bark, and fruit extracts. Method: Antioxidant activity was carried out by Burits and Bucar method with slight changes and about anti-inflammatory (inhibition of albumin denaturation) assay was carried out by Dunnet method. Result: In these experiments, the results obtained were positive. The result, when compared among the three parts, showed more positive results in antioxidant assay SNPs synthesized from fruit, and dominated results in the anti-inflammatory test SNPs synthesized from the bark. Conclusion: By studying the applications of SNPs it is confirmed that the biosynthesized silver nanoparticles (SNPs) are helpful in the production of various medicines hence SNPs can be recommended ingredients for biomedicine.

Abstract: Novel properties are observed to arise at 2d level, which is typically absent in their bulk counterparts. Graphene, the most widely studied 2D material. Recently, the other 2D group-IV materials, silicene, germanene and stanene, have been realized by epitaxial growth on substrates and attracted tremendous interest due to their extraordinary properties. The discovery of stanene, a buckled monolayer of tin atoms arranged in a 2D honeycomb lattice, has explored enormous research interest in the materials in the two-dimensional (2D) realm. Stanene exhibit ductile nature and hence could be easily incorporated with existing technology in semiconductor industry on substrates in comparison to Graphene. the systematic investigation of phonon properties for stanene is needed. The general three dimensional continuum model of phonons in two dimensional materials is developed. At present, our research group find the lattice dynamical matrix and secular equations with solutions, phonon dispersion curve and Phonon density of states using Adiabatic Bond Charge Model with the help of MATLAB. We hope that phonon properties of Stanene will be good fitted with experimental data.
