Abstract

Ten half-sib progenies of Albi ia lebbeck belonging to different places of Allahabad regions were sown in glasshouse and field condition with a view to assess the impact of two different environments on the expression of genetic diversity using non-hierarchical Euclidean cluster analysis. Superior tree progenies were grouped into four clusters under glasshouse as well as in field atmosphere. Families of plus tree S₉ and S₁₀ formed one cluster both under glasshouse and field back ground. Inter cluster distance was found to be highest between cluster IV and II (59.06) under green house whereas, under field condition cluster III and I showed maximum (51.80) inter cluster distance. Within a cluster showed low intra-cluster distance <1.681), under both the environments, revealing their genetic closeness. Leaf area followed by seedling height contributed maximum to the total divergence and played a predominant role in creating the genetic diversity.

Abstract

Materials research group at the Department of Physics, Tezpur University is involved in research on electroactive polymers viz., polymer electrolytes, conducting polymers and their nanocomposites and investigation of Swift Heavy Ion irradiation on them. Different polymer electrolyte systems including PVdF-HFP undoped PAni nanofibers dispersed, PEO-MMT, PMMA-MMT, PVdF-MMT based nanocomposite gel polymer electrolytes have been synthesized and characterized by ionic conductivity, electron microscopy, XRD, FTIR, DSC and electrochemical measurements with a view to gain an insight as to how ionic conductivity in polymers can be understood in terms of the dynamic aspects of local structure, including changes in coordination number and in the distribution of electronic charge. In conducting polymers, research has been taken up to develop conducting polymer based nanostructures and nanocomposites using soft template, rapid mixing and interfacial polymerization techniques for their applications as actuators, chemical and biosensors, and antioxidant materials. Understanding the structure property relationships in these technologically important materials using various diffraction, microscopic and spectroscopic techniques is of major interest. The group is also working on the study of swift heavy ion induced modifications in electroactive polymers in collaboration with Inter University Acceleration Centre (IUAC) New Delhi.
