During the past 32years, more than 103000 research articles with term graphene in the title or in manuscript have been recorded in the Scopus database. This exceptional reputation of graphene is due to numerous reasons; the most significant one appears to be its incomparable physical properties, resulting in real-time application in many fields of science and technology. That's why it seems to be absolutely justified that "graphene possesses everything's what you want". This article is a tribute to the researchers who contributed to the background of the current face of graphene. In this short paper we are presenting the contributions of initial research articles on graphite that are responsible for the present status of graphene and led the research interests of materials scientists toward the potential applications of graphene and its derivatives. The current progress in graphene research output of renowned scientists around the globe is also evaluated based on the Scopus and Web of Science databases. However, a particular emphasis is focused on the current technological innovations (2010-2017) based on graphene, as well as mostly prototype devices fabricated using graphene as a key material along with discussing the recent challenges in graphene nanotechnology, and a recommendation of the ways to advance the commercial readiness of the products based on graphene and their derivatives. In addition, we have also briefly discussed the limitations of graphene, future prospects and present global market trends of graphene-based products.

The present work portray the Aspidopterys Cordata (AC) leaf extract-assisted fabrication of zinc oxide nanospheres (ZnO NSs) using an eco-friendly approach for antibacterial and antioxidant activity. As fabricated ZnO NSs were characterized by X-ray diffraction (XRD), fouriertransform infrared (FT-IR), energy dispersive X-ray diffraction (EDX), UV-Visible diffuse reflectance spectroscopy (UV-DRS), Raman, X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), and transmission electron microscope (TEM) for authenticate the structure, shape, size, chemical state, and morphological facet. XRD pattern showed the strong and intense diffraction peaks indicating the formation of crystalline ZnO NSs with hexagonal phase. Further, EDX revealed the formation of highly pure ZnO with signals of Zn and O elements. UV-DRS reveals absorption band at 370 nm, assigned to the intrinsic band-gap absorption of ZnO, owing to the electron transitions from valence band to conduction band. TEM images inveterate the formations of ZnO NSs with mean particle size of 11.6 nm. The antibacterial activity of ZnO NSs was examined against grampositive (Staphylococcus aureus) and gram-negative (Proteus vulgaris, Escherichia coli, and Klebsiella pneumonia) human pathogenic bacteria using ZnO NSs by agar-well diffusion method. Furthermore, ZnO NSs exhibited significant antioxidant activity against scavenging 1, 1-Diphenyl-2-picrylhydrazyl (DPPH) free radicals.
