All of us are familiar with the proverb ‘Sone pe Sohaaga’- aren’t we? What exactly this means? In English, the closest to this is ‘Icing on the cake’ or ‘Cherry on top’. Broadly, this proverb means additional benefit to something that is already considered positive or beneficial. For food, this indicates addition of taste or aroma enhancer; insertion of an appropriate stone to a pendant could do the same to the beauty of an attractive necklace. But you wonder what this has to do with science? Yes, it has a lot to do with science!The action hermitically expressed in this canindeed generate a huge interest among chemical engineers who look for accessing, through liquid solvent engineering, new environment friendly reaction media for large scale industrial applications as well as basic science researchers who searches for non-uniformity inside seemingly uniform distributions. Let us elaborate a bit with some examples.
