Title: Fluorescence Enhancement Studies Of Eu+3 by Phenylalanine and Phenylacetic Acid Authors: Shekhar, Mrinal Abstract: Lanthanides have very poor luminescence intensity because of their poor molar absorption co-efficient and poor quantum yield. In order to have potential utility of lanthanide luminescence in the biological and electronic (optical light emitting diodes) fields the luminescence intensity of lanthanides must be enhanced and this is achieved via ligand sensitization. This process involves two steps: First the co-ordination of ligand to the lanthanides and finally energy transfer from the ligand to the lanthanides. Further enhancement is achieved by encapsulating the lanthanides in a protective sheath by some synergistic ligands thereby preventing quenching by water molecules. In recent years a new approach has been to make use of ionic liquids which provides the advantages of both sensitizers and synergistic ligands. The aim of this work is to enhance the luminescence of lanthanides using amino acids as sensitzers and to compare the level of sensitization achieved by phenylalanine, benzoic acid and phenylacetic acid. The study of Amino acid as sensitzer is required in order to investigate if amino acids can be used as a part of ionic liquid. Apart from this a kind of comparative study will give information on the effect of the spacer CH2 group. The lanthanides being used was Eu+3.In order to obtain further enhancement the experiments were performed in presence of synergistic ligands like TOPO in a micellar medium. The experimental work was supported by some theoretical calculations to determine the reason behind the differences in the level of sensitization

Title: Virtual Education: A potential alternative for improving Undergraduate Science Education in India Authors: Kohli, Bharat Abstract: In India, the condition of undergraduate science education is in a bad shape as teaching standards at University and college level are way below the global standards. In order to work towards a sustainable and equitably developed nation it is imperative that we seek alternatives to raise the higher education standards. I see virtual education as a very viable solution to address this problem as it has a potential to satisfy large needs using less resources. Here is an attempt to build an argument in favour of virtual education medium as feasible and beneficial alternative to conventional university teaching.. In addition to this, there is also an attempt to find out the characteristics of best mode of lecture delivery in virtual education. Since I have studied biology in my undergraduate courses, I have chosen “Evolution” as a topic of for this intervention. I have chosen “Evolution” because this topic in biology has been my topic of interest during my graduation. In addition to this, it’s also the central topic in the biology.
