Changes in Periodic Table of Chemicals….

We know that everything in the universe is made from the atoms. They are the basic building entities. Atoms are not solid entities but are made of dense nuclei surrounded by fuzzy cloud of electrons whizzing in the outer. Nucleus is made of protons and neutrons. Things don’t not end here. Nature is very complex. Even the atoms of same elements can have different number of neutrons making them have different weights. Such atoms are called isotopes. Atoms of same element or different elements can combine in umpteen ways resulting in diverse molecules and different substances from very simple molecules… Read More »Changes in Periodic Table of Chemicals….

Is there life on Mars? Again Microbes hold the key

Earliest life of single cell evolved into 3 branches having distinct traits. The branches further subdivide into more branches on the evolutionary tree of life called Phylogenetic tree of life. The first three branches are called Bacteria, archaea and Eucaryota. As we can see in this tree, there is a member of archaea family with the name Methanogen. This microbe holds the answer for presence of vast quantities of methane which is trapped inside the ice cages called methane hydrates. These hydrates are found in Earth’s in permafrost regions having very low temperatures or under the deep sea floor. Water… Read More »Is there life on Mars? Again Microbes hold the key

In Search of Chemist’s pure water

Chemist’s pure water which is formulated as H2O exists only in the theory. In the laboratory too, it has to be prepared from the water from the tap. The reason is its high polarity and very high dielectric constant which makes it a potent solvent. It can dissolve inorganic salts, polar organic compounds, acidic, basic and polar gases. It also carries suspended matter like clay particles in the form of colloids. Some of these are loosely suspended and separate out with time by sedimentation and other are stable and has to be destabilized by using defloucculants to settle them out. … Read More »In Search of Chemist’s pure water

Microbes Rule Our World

There are trillions of microbes which inhabit an adult body. Looking at the sheer numbers, one may think that all these microbes are responsible for the ailments only. But this is not true. On the contrary, microbes are much more our friends than our enemies. Microbes run this world despite their infinitely small size. Their success lies in the sheer numbers and ability to adapt to the changing conditions. Following is the list of some species of the microbes that make our lives better: Bacillus thuringiensis A common soil bacterium that is a natural pest-killer in gardens and on crops.… Read More »Microbes Rule Our World

Mighty Microbes !!

Microbes may be very small in size but their sheer numbers and remarkable adaptability to the existing climates is astounding. The word microbe is derived from micro-organisms meaning they are so small that they cannot be seen with naked eyes. A microscope is required to see them. But these tiny organisms are so active that they can bring about mammoth changes into the environment in which they live. Most of the chemical changes on the earth are brought about by these microorganisms. When the earth first formed, the atmosphere consisted only of carbon dioxide and water. Due to this iron… Read More »Mighty Microbes !!
