Abstract
Many high-Tc superconductors, Iron-based superconductors, and other recently discovered superconducting materials show the signature of the existence of a strange Pseudo Gap above the superconducting transition temperature. Various experimental techniques such as NMR, Tunneling, and ARPES suggest that the pseudo gap does not change with temperature. As evidenced by these experimental results, the Pseudo gap possesses a d-wave pairing symmetry similar to the superconducting energy gap. The physical properties show unusual behavior in the non-superconducting state where a pseudo gap exists. Based on experimental evidence we argue about the origin of the pseudo gap in these superconductors. Although a complete understanding of the mechanism is lacking, the existence of preformed cooper indicated by various experimental probe pairs seems to be responsible for the origin of the Pseudo gap.
Keywords: Pseudo Gap, Unconventional Superconductors,

Abstract
Context: there is an urgent need to prove the authenticity of ayurvedic medicines in the light of modern scientific knowledge. Aims: The GC MS analysis of one herbal oil, Kunthalakanti thailam to understand the molecules present there in. Materials and Methods: Kunthalakanti thailam was bought from standard Ayurvedic vendor from Chennai. It was processed and GC MS analysis was done by standard procedures.. Statistical Analysis used: No statistical data is used. Results: The GC MS report indicated the presence of mostly fatty acids and their esters which have potent antioxidant, anti-allergic properties such as N Hexadacoinc acid, 2-Methyl-3-93- methyl-but-2-enyl)-enyl)-oxetane, 3, 7-Decadien-2-one, 10-(3,3-dimethoxyloxiran dimethyl-, (E,E)-,+/-. Etc. have medicinal activities which help in keeping the homeostasis of the scalp and maintain good health to hair follicles and hair. Some important biomolecules which have medicinal properties supporting the validity of skin treatment with this oil. Conclusions: The presence of these biomolecules having medicinal properties supports the validity of Kunthalakanti thailam as skin and hair health treatment.

Abstract
Marine algae are multi cellular plants commonly known as seaweeds having potential applications in biofuel production, drug and nutritional analysis. The current study, predicts the production of biodiesel from trances terification of algae lipid or oils. Seaweeds are collected from different coastal regions of Tamil Nadu and are subjected to lipid extraction by using various solvents. The yield of biodiesel is depending on the amount of lipid extracted from algae. In the present work, the macro algae species such as Gracilariacorticata, Chaetomorphaattenina, Chladophoravagabundaare taken to compare the yields of biodiesel. The result suggests that the marine algae Chladophoravagabunda yieldsmore biodiesel in comparison to the other algal species and is a potential source for biodiesel.
Keywords:Biofuel,Seaweed, Transesterification, Gracilariacorticata, Chaetomorphaattenina, Chladophoravagabunda.
