Brief of confined growth nanomaterials and influence of nanoscale on fundamental aspects primarily band gap, surface area, surface atom density, surface energy, dangling bonds, Gibbs free energy, nucleation, cohesive energy, lattice parameters, strains, frequency, and particle velocity are discussed. One can correlate the physical properties of nanomaterials with help of these phenomenologies. A classic illustration and future scope in both traditional and advanced ceramics by nanoscale modulation are highlighted. Nanomaterials handling and ethical issues are enlightening to make aware of nanoresearch. Eventually, the bird-eye view has been illustrated in the perspective of case studies like energy, environment, and health issues.
