Q.8 In context with the Graphene which among the following statements are correct ?

1) It is an allotrope of carbon with single-layer transparent sheet

2) It has a low weight which makes it strong 100 times more than the steel

3) It has a two dimensional properties

Codes:

A) 1 & 3

B) 2 & 3

C) 1 & 2

D) 1,2,3

Ans. D

Graphene is pure carbon in the form of a very thin, nearly transparent sheet, one atom thick. It is remarkably strong for its very low weight (100 times stronger than steel and it conducts heat and electricity with great efficiency. While scientists had theorized about graphene for decades, it was first produced in the lab in 2004.  Because it is virtually two-dimensional, it interacts oddly with light and with other materials. Researchers have identified the bipolar transistor effect, ballistic transport of charges and large quantum oscillations.

4) Bio-fertilizers do not contain any chemicals which are harmful to the living soil

5) They fulfil plant nutrient requirements by supplying the organic nutrients through microorganism and their byproducts
