High Pressure Equation of State for Nanomaterials

Shanker Equation of State is used to study the volume compression of nanocrystalline materials under different pressure. On comparing with the experimental data it gives good results at low pressure, but for higher compression it deviates from the experimental points. Therefore, the Equation of State is modified empirically to study the pressure-volume relation for nanomaterials, namely, n-Rb3C60, n-CdSe (rocksalt phase), n-TiO2 (anatase and rutile phase), Fe-filled nanotube, and γ-Fe2O3, at high pressure. The results obtained from the empirical Equation of State are found to be in better agreement with the available experimental data.

Polyphenols: An excellent source of antioxidants for human health

Polyphenols are secondary metabolites of plants and are generally involved in defense against biotic & abiotic stresses. Polyphenols are well-known health actives, which mainly acts as antioxidant. Recent studies strongly suggest that long term consumption of diets rich in plant polyphenols offer protection against development of various diseases e.g. cancers, diabetes, osteoporosis and neurodegenerative diseases etc. This article focuses on the present understanding of the biological effects of dietary polyphenols and their importance in human health and disease.
