Abstract: The world population is increasing and burst of portable electronic devices, automobile and other industries, the consumption of energy in many forms has been intensively escalated. The world energy sources are being consumed fast and this has put the world in a ditch of energy crisis. On the other side, the availability of sustainable energy is crucial for the economic growth and industrialization, at the end of day sufficient and inexpensive energy is the most important demand of today. So this is the time to conserve the nonrenewable energy sources as well as to find the alternative sources of energy production and storage. It needs to response of modern society and emerging ecological concerns, the new, minimum-cost, and environmentally friendly energy conversion and storage systems should be investigated, and research and development of this field should be rapidly accelerated. Tailored characteristics of nano materials and compound at the nanometer scale, offer unique properties and will play a vital role in the development of new energy technologies for energy production and storage. The objectives of the research have to introduce the nanomaterial for energy production & storage. At the last there have a great potentiality to produce energy & storage by nanomaterials.

Abstract: Contamination of fresh and marine sediments and water environments by oil spills, urban runoffs, industrial and domestic effluents is demonstrating to be of critical concern as the presence of contaminants affects aquatic organisms and can quickly disperse to large as highlighted by the recent Gulf oil spill disaster. Polycyclic aromatic hydrocarbons (PAHs), Poly chlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and heavy metals like mercury, lead and manganese are among the ubiquitous trace contaminants of marine and freshwater systems. Presence of these contaminants raise concerns as small quantities of the organic chemicals have been displayed to be carcinogenic to mammals and can pose a prohibition to both human health and the aquatic biota. Innovative operations for treating wastewater containing heavy metals often include technologies for reduction of toxicity. Nanotechnology has rampaged plethora of scientific and technological fields; environmental safety is no exception. One of the most promising and well developed environmental applications of nanotechnology has been in water remediation and treatment where different nanomaterials can help purify water meanwhile different mechanisms including adsorption of heavy metals and other pollutants, removal and inactivation of pathogens and diversion of toxic materials into less toxic compounds. Today nanoparticles, nanomembrane and nanopowder used for revelation and removal of chemical and biological substances include metals (e.g. Cadmium, copper, lead, mercury, nickel, zinc), nutrients (e.g. Phosphate, ammonia, nitrate and nitrite), cyanide, organics, algae (e.g. cyanobacterial toxins) viruses, bacteria, parasites and antibiotics. By tracing these technological advances to the physicochemical properties of nanomaterials, the present review outlines recent development in nanotechnology for wastewater treatment. The discussion covers candidate synthesis of magnetic nanomaterials (MNPs), properties and their mechanisms in water purification.
