Bio-degradable Polymers
Biodegradable polymers are a specific type of polymer that breaks down after its intended purpose to result in natural byproducts such as gases (CO₂, N₂), water, biomass, and inorganic salts. These polymers are found both naturally and synthetically made, and largely consist of ester, amide, and ether functional groups. Their properties and breakdown mechanism are determined by their exact structure. These polymers are often synthesized by condensation reactions, ring opening polymerization, Read more about Bio-degradable Polymers[…]

Integral as Anti Derivative
Primitive or anti-derivative of a function: A function ø is called a primitive or an ant derivative of a function f(x) if ø’(x) = f(x). Let ø (x) be a primitive of a function f(x) and let C be any constant then, d/dx [ø (x) + C] = ø’ (x) = f (x) [∵ø’ (x) Read more about Integral as Anti Derivative[…]
