While nanoparticles have taken a large share in nanotechnology articles, graphene and quantum dots are recently drawing a great deal of interest.
The strength of a building or a structure is directly dependent on the strength of its subunits. Similarly, nanomaterials dictate the overall characteristics of nanotechnology products. Therefore, a number of research strives to answer which nanomaterial is better suited for any given product.
A quick review of the StatNano’s nanomaterial database from 2016 shows that “Nanoparticles” with 62,208 followed by “Graphene” with 23,333 articles are the first and second most published subjects in nanotechnology. The third and the fourth places belong to “nanotubes” and “nanocomposites” with 19337 and 18631 papers, respectively.
Interestingly, from the number of publications’ standpoint, “nanoparticles” has higher rank than all other subjects combined. Nevertheless, attention to graphene by the scientific community has been rising in the recent years. A review on the cited scientific publications from StatNano database shows that while the number of publications on “nanoparticles” is exceedingly higher than that on “graphene”, their citations per article (or h-index) are low. In fact, the publications associated with “graphene” have the largest share in citation which has driven many researchers to invest on this material.
Research on quantum dots have been growing over the last few years, through which the position of this nanostructure from the citation and h-index standpoint has greatly improved. The potential capabilities of these nanomaterials in the development of displays and their importance in improving image quality have attracted the attention of many companies. In the forthcoming years, the share of non-metallic quantum dots will expectedly surpass their metallic counterparts.
