Christmas Tree Model of Periodic Table of Chemical Elements
Gnanamani Simiyon G Mary Vergheese Nancy Sagunthala J Nivetha B
Periodic table consists of elements arranged based on theiratomic number to understand their properties. Many periodic table representations have been reported, but the position of hydrogen and f-block elements remains unclear. We report here a simple ‘Christmas tree model’ as an alternativeto the modern periodic table.

From Sink to Shelf: Organic Solvents
Gnanamani Simiyon G Mary Vergheese T B Nivetha B
One of the common physical chemistry experiments carried out in undergraduate programs is the determination of the partition coefficient (Ko) in which a solute is distributed between organic and aqueous layers. After the experiment, the used-up organic layer and stock organic layer are discarded without proper measure, which poses a serious threat to our environment. In this article, we propose a simple, cost-effective and environment-friendly method to recycle the organic solvent used during the experiment.
