Biodegradable polymers
These are the polymers that are degraded through micro-organisms in an appropriate period so that biodegradable polymers and their degraded products do not reason any serious influences on the environment.
In biological systems, biopolymers degrade majorly by enzymatic hydrolysis and to a few extent by oxidation. Hence, in show of the disposal causes of polymer waste and for developing polymers for another safe uses in human systems, tried have been build up to develop biodegradable synthetic polymers. These synthetic polymers generally have functional groups that are generally available in biopolymers and lipids.

How is harvest maturity identified? Before harvesting, the first thing to be looked into is the identification of harvest maturity. We have already seen what the term ac
What are laws of crystallography?How it helps us in the study of crystal structure
Each element has a unique number of protons. This unique number is known as the element's atomic number . All atoms of a given element have the same atomic number. For example:
An element L has 9 protons and valency 1. Another element M has valency 3 and 5. What is the difference in the number of electrons in L and M ?
