Bacteria can thrive on almost anything and adapt themselves to very diverse environments. They can subsist on substances like cellulose which we humans cannot assimilate. They can breakdown poisonous gases like hydrogen sulfide and absorb nitrogen from atmosphere and fix them into the roots of many plants which plants use as fertilizer. Bacteria can even breakdown crude oil. Crude oil consists of millions of hydrocarbons which are composed from carbon and hydrogen. These compounds range from the simplest molecule called methane made from 1 carbon atom to giant molecules containing even more than 50 carbon atoms. Many of these bacteria… Read More »Bacteria in Oilfields
Everything is identical about these twins. Number of atoms, type of atoms are same. Only difference is the spatial arrangement of atoms or groups of atoms attached to the carbon atoms. There is one more trait of these twins-they are mirror images of one another. They are called stereoisomers. Stereo means spatial. There is a slight differences in the reactivity of these members. One very interesting property of these molecules is that they rotate the light passing through their solution in equal and opposite directions called Levo and Dextro. When such compounds are synthesized in the laboratory, we obtain both… Read More »Optical Isomerism
Many a times you must have experienced in your life that you cannot recall a certain incident, name of a person or a book or author although at other times you remembered it so well. In those circumstances, the harder you try to recall more it eludes you. It is not the case of poor memory or age as it happens with everyone at one time or another. You leave it frustrated and become busy in some other work and in a flash the things will come to your mind. The same has happened to many great scientists and authors.… Read More »Achievements of a wandering mind
The story of water cycle
Carbon is the atom on which the life on the earth is based. Though it is not a complicated element having only 6 atomic number, it ability to form compounds with hydrogen, oxygen, sulfur and host of other atoms and its ability for catenation makes it the most distinguished element for us. We owe our existence to it. Most of the macromolecules which are bodies are composed of contain carbon, hydrogen and oxygen. This simple element show another very surprising properties. One of them is the allotropy. Two allotrope are two different arrangements in which an element can exist. Till… Read More »Graphene: Size Zero Allotrope
Nature is a great chemist. It synthesizes millions of compounds every moment ranging from simple molecules like methane to very complex molecules like carbohydrates, cellulose and proteins. Most of these compounds are synthesized by plants. From the plants they are passed on to animals because the animals cannot synthesize their food by themselves. But there are many chemical reactions occurring inside the cells like breaking down the complex molecules and unlocking the energy which is stored in them. Where does all the energy locked inside the different molecules come from? Most of it is derived from the Sun light. In… Read More »Chemistry by Nature
What you will say, We will say also. Brine is mud, mud brine. Deep is shallow and Shallow deep. Pigeons crows and Crows pigeons. What you will say, We will say also. Sun comes in night, Moon in the day. Night is bright, Dark is the day. DNA is RNA, RNA DNA. Oil is heavy, Water lighter, Gas is heaviest. What you will say, We will say also. Our faith unshakable, in you is blind. No questions, No queries, No F&A Q s. Your word is final, O’ Nimrod!, bless us bless us!
