Nanoparticles such as metals, semiconductors and metal oxides are of great interest for a wide variety of applications in the field of information, energy, environmental and medical technologies due to their unique or improved properties determined primarily by size, composition and structure along with their selforganized film structures. In this presentation, Japan’s national project on nanop...

Large amounts of global sources of remote natural reserves gas are identified along with the main objective to allow energy contained in to be moved economically to the market. The current options that are adopted to export natural gas are basically two:1. To liquefy the gas and ship it as LNG (Liquefied Natural Gas). 2. To convert it to bulk petrochemicals in particular methanol or ammonia and...

two facile and low cost routes were used for the synthesis of if-ws2 nanoparticles. in this paper, preparation of if-ws2 nanoparticles with two different methods was investigated. in the first method, wo3 nanoparticles were reacted with h2s gas in n2/h2 reducing atmosphere at 900 oc. the as-synthesized if-ws2 nanoparticles are spherical shape with an average size of about 70 nm.  in the second ...
