This article lists 75 Nanomaterials MCQs for Engineering Students. All the Nanomaterials Questions & Answers given below include solutions and links to the relevant topic. This is helpful for users who are preparing for their exams and interviews, or professionals who would like to brush up on the fundamentals of the Nanomaterials.
The word nano corresponds to 10^-9 of a unit that is one-billionth of a unit. The top-down approach and bottom-up approach are the two types of approaches that are used to reach the nanoscale. The nanostructure material may be quantum dots, nanoparticles, nanorods, nanofibers, nanotubes, and so on.
When one dimension of the material is at least between one to hundred nanometers then that material is called a nanomaterial. The nanomaterials are divided into four classes they are 1-D, 2-D, 3-D, and 0-D dimensional that including quantum dots, nanoparticles, etc.
The one-dimensional nanomaterials include nanotubes, nanorods, nanowires, etc. The two-dimensional nanomaterials include thin films, nanofilms, graphene nanosheets, etc. The three-dimensional nanomaterials include bundles of nanowires, bulk powders, nanoparticles, etc.
The nanomaterials are of two types they are naturally occurring nanomaterials and manmade materials. The virus, sea spray, volcanos, etc are the naturally occurring nanomaterials, the cooking smoke, industrial effluents, etc are the incidental nanomaterials. The main disadvantage of nanomaterials is they are unstable and recycling is hard.
