There has been an increasing interest in synthesizing the novel composite polymer electrolyte (CPE) for use in lithium batteries in recent years. This paper describes the preparation and characterization of CPE containing lithium perchlorate based on polyindole-NiO nanocomposite. NiO nanoparticles were added to the monomer solution before the polymer formation in the presence of a surfactant to get the PInNiO nanocomposite. The thermal properties, surface morphology, and structural studies of the electrolyte were investigated by TGA, SEM, TEM, and XRD. An enhanced conductivity of 2.62 Â 10 À4 S cm À1 at 45 C for the composite polymer electrolyte was determined from impedance studies.

Nature is God's gift to human beings. Natural products are a source of new chemical diversity and are the choice of today's world. Nature itself gives remedy to all our health problems. The sources of natural product are plants, animals and microorganisms. Among them plant and its products are more reliable for its renewability and therefore, considered as fortunate thing for human welfare. Our traditional system of medicine which has been followed by our ancestors has its own impact on human life. Due to the inadequate knowledge many plant derived products (drugs) has not yet been explored to the society. We are having many side effects and long term complications in synthetic drugs. Our aim is to mine the precious data about the plant Argemone mexicana. Now-a-days people prefer a drug which has no side effects. For that, the plant Argemone mexicana is a boon to the human being as it has a number of miraculous compounds to cure a various types of diseases. Single plant has a lot of uncountable benefits in drug discovery and which gives a base for new drug discovery. This plant is a weed, easily available and it does not require any special care which forms the base to develop a drug in socio economic form so that it could be made available to all people. This chapter provides an insight into various interesting pharmacological properties viz., Antidiabetic activity , Anti-Cancer activity, Anti-HIV activity, CNS related activities, Wound recovering action, Anti microbial activity, Antioxidant activity, Anti-inflammatory, analgesic, antipyretic activity, Hepatoprotective activity, Anti-fertility activity, Antiallergic activity, Nematicidal activity, Allelopathic effect, Antihelmintic activity, Larvicidal activity, Antifeedant action etc., which has been reviewed from different literatures in scientific journals. This present review would kindle many of the young minds to turn towards the nature i.e., plant based novel drug discovery with in-depth and extensive studies in all relevant aspects. Hence the paramount importance of this review about Argemone mexicana will be very much useful to the society.

The current investigation dealt with pharmacological study of Coccinia indica (wild). For past several years, various medicinal plants were increasingly studied for the treatment of different ailments. The normal variety of C. indica was extensively used for home remedies and household purposes. But the wild variety of C. indica tastes bitter and showed good pharmacological activity. The current study revealed that ABTS assay was shown more scavenging activity than DPPH assay. The methanol extract of C. indica showed effective antioxidant activity than aqueous extract, but the property of anti inflammatory, aqueous extract of showed C. indica showed better anti inflammatory activity.
