> Today's emerging nanotechnology approaches aid in making assorted dimensional reconfigurable materials for progressive development and advanced engineering functions in modern S&T. Reconfiguration augments new functionality in the resultant multiphase matrixes such as composite, blend, and hybrid. This introductory chapter is a preamble to interactive materials for the basic skeletal reconfiguration to derive specific applications. Rational designing and systematic reinforcements at various material scales are fundamental to manipulations native limiting characteristics and functionalities, which are unattainable through usual/ non-reinforced materials. Skeletal reconfiguration in materials can be decisive to fabricate the particle, thing, and device at the atomic and molecular dimensions being achieved through assorted multidisciplinary fields such as biotech, physics, chemistry, plastic, polymer, and nano-engineering. Reconfigured/reinforcement reduces innate spatial dimension or captivity within the crystallographic phase of

material by virtue of altering its physical, mechanical, thermal, optical, electrical, and electronic properties. In general, reinforced material matrixes contain three nanoporous skeletons, namely: 3-D/zero dimensional (e.g., particle, grain, shell, capsule, ring, and colloidal), 2-D/one dimension (e.g., quasi crystal, nanorod, filament, tubes and quantum wire), and 1-D/two dimensional (e.g., disc, platelet, ultrathin film, super lattice, and quantum well).

This chapter cited many smart matrixes yielded through rational designing of flexible materials skeletons for innovative findings in many domains including sensor, photo-detector, LED, laser, FET, physics, catalysis, biomedicine, environmental, aerospace, and construction. The introductory chapter overviews assorted 1D/2D/3D matrixes, which appeared to be best choice for soft and hard composites besides modernization of many fields including bio-electronic/optic, drug therapy, medical product, tissue engineering, smart battery, super-capacitor, electro-catalyst, bio-adsorbent, and manufacturing. While going through this chapter and the entire book, researchers will be aware of the superiority of reconfigured matrixes by virtue of designed features such as better load reassignments, tailored interfaces, increased strength, heat protection, and impactful solidity viable at low cost with end-use components. In a nutshell, reconfigured material matrixes are promising and notable due to novel advancements and a myriad of utility in futuristic S&T.
