All the Nanoscience 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 Nanoscience. Nanoscience is a study of nanoscale materials that include experiments and theories to explain different properties and phenomena associated with nanomaterials. Nanoscience involves understanding the fundamental interactions of systems confined to nanoscale dimensions and their properties. Nanoscience is the theoretical modeling of nanoparticles, where we study the information of nanoparticles at nanoscales and analyze the properties and behavior of nanoparticles. The nanometre is defined as one-billionth of a meter and it is denoted by nm. In greek nano’s means little old man or dwarf. The samples that are at the molecular or atomic scale where a chemical reaction occurs are known as nanoscale. The majority of the atoms at the nanoscale split between the inside and surface of an object and the melting point is lower for smaller particles on the nanoscale. Nanoscience is the science of objects with typical sizes of one to hundred nanometers, whereas nanotechnology is the science and engineering of modeling and manipulation of matter on molecular, atomic, and supermolecular scales. 1).
