DMPQ-CNTs have unique thermal and mechanical properties that make them intriguing for the development of new materials. Discuss

Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter of less than 1 nanometer (nm) or multi-walled (MWCNT), consisting of several concentrically interlinked nanotubes, with diameters reaching more than 100 nm. Their length can reach several micrometers or even millimeters. … Read more

DMPQ:Write short note on Genetic modified crops.

Genetically modified crops are plants used in agriculture, the DNA of which has beenmodified using genetic engineering techniques. The aim is to introduce a new trait to the plant which does not occur naturally in thespecies. In food crops include resistance to certain pests, diseases, or environmentalconditions, and improving the nutrient profile of the crop. … Read more

DMPQ- What do you understand by the term Super Earth?

In the strictest sense, a super earth is just a planet with more mass than Earth, but less than a larger planet like Uranus or Neptune. So, super earths made of rock and metal, or even ice and gas. These planets could have oceans and atmospheres, or made of nothing but hydrogen and helium. The … Read more
