Phyllanthus muellerianus is a large genus of the Euphobiaceae, is popularly known as ‘nvo nkwo’in Oghe traditional medicine. This species is used in the folk medicine for the treatment of sexually transmitted desieases. The aim of this study was to isolate and identify and spectroscopic characterize of sample GH3 from leaves of P. muellerianus. Sample GH3 from leaves of P. muellerianus was analyzed for their absorption, functional groups (CH, H, OH and NH) and 1H NMR resonance peaks (7.2 ppm and 6.7 ppm), resulting in the identification of benzopyran’s groups, suggesting 2H-1-benzopyran (chromene). The identification of benzopyran’s groups is here reported for the first time in P. muellerianus.

In this short communication, an integrated process concept for detoxification of chromium (VI) contaminated water with Polyaniline/MCC composite is proposed. The preparation of composite involved in-situ oxidative polymerization of aniline in the presence of MCC (a bio-based material); the industrially favorable and cost effective oxidant ammonium persulphate (APS) was used. Under the conditions studied, the preliminary results reflected that the proposed concept was quite effective in the detoxification of the model solution. It is worth expecting that the use of PANI-engineered cellulose fibers prepared using low cost oxidant may serve as an interesting alternative for industrial water treatment.

Graphene, a carbon, displays unique 2-D structures with preternatural physical, chemical and electronics properties that necessitated its applications in different fields of engineering systems. Among these applications, bioelectronics application of graphene has attracted an increasing interest over the last years. The advantages conferred by the physical, optical and electrochemical properties of graphene-based nanomaterial have contributed to the current variety of ultra-sensitive and selective biosensor and sensors devices, Nano electronics, super-capacitors, solar cells, batteries, flexible displays, hydrogen storage in electronics. This paper provides a review on graphene variant properties and their applications especially in bioelectronics
