A nanoparticle (or nanopowder or nanocluster or nanocrystal) is a microscopic particle with at least one dimension less than 100 nm. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields. Nanoparticles are of great scientific interest as they are effectively a bridge between bulk materials and atomic or molecular structures. A bulk material should have constant physical properties regardless of its size, but at the nano-scale this is often not the case. Size-dependent properties are observed such as quantum confinement in semiconductor particles, surface plasmon resonance in some metal particles and superparamagnetism in magnetic materials. The properties of materials change as their size approaches the nanoscale and as the percentage of atoms at the surface of a material becomes significant. For bulk materials larger than one micrometre the percentage of atoms at the surface is minuscule relative to the total number of atoms of the material. Journals are the major source of knowledge for young and aspiring generations who are keen in pursuing their careers in science. This system provides easy access to networks of scientific journals. Authors who contribute their scholarly works to Open Access journals gain remarkable reputation as the research scholars explore these works extensively. This process assures considerable impact factor for the journal and good reputation to the authors that add value to their Academic Performance Index (API) Score. Because of the free access open access journals impact factors are improving.
