Superconductivity is a transpiring technology for high performance electronics. It offers unique and beneficial attributes for signal processing, communication systems and industry. Yet, industry faces technical hurdles and market obstacles for making profit. The paper presents his vision of the future of superconductor electronics, and perspective of the past, and approach toward achieving success. Overcoming the technical and market barriers will determine the growth of superconductivity in the electronics industry, and coincidentally of applied research in this technology.
Lots of significant improvements in the properties of superconducting materials have occurred recently. Considering these improvements the latest generation of wires, cables, and tapes are done. Promising new materials such as MgB2 have been discovered and are being studied in order to find out their potential for new applications. In some cases, the understanding and development of materials with significantly improved properties are done.
In this paper we will review the key advances take place in materials used for superconductors. Initially processible conjugate polymers from organic semiconductors to organic metals and superconductors are described. Later coated conductor development (in which high performance YBCO coated superconductors), Fabrication of superconducting composites by newly developed liquid quenching technique, Development of Nb tube processed Nb3Al multifilamentary superconductor are given.
At the end short information about an approach to next generation high temp superconducting wire, latest achievements in the use of semiconductor for large scale application is given.
Recent progress was on second generation of biaxially aligned coated conductors victimization the less aeolotropic YBa2Cu3O7 structure has been speedy, suggesting that it too would possibly enter service within the close to future. The invention of electrical conduction in MgB2 below thirty-nine K in 2001 has brought yet one more candidate material to the large-scale applications combine.

Polymer Electrolyte Membrane Fuel cells are the key to sustainable energy production in the near future. The authors combine the specifications of the variety of polymers used for manufacture of high as well as low temperature polymer electrolyte membranes, the various combinations of catalyst layers and gas diffusion layers that are available and its applications in terrestrial transport systems. Polymer electrolyte membrane fuel cells function depending on the arrangement of the membrane electrode assembly, which directly or indirectly relates it to the type of polymer membrane used in the fuel cell. As the temperature of operation increases, the power density increases which basically happens due to greater allowable driving force difference. The authors attempt to classify these fuel cells for into high temperature and low temperature. The following article is a review of the detailed analysis of each component of the Polymer Electrolyte membrane fuel cell particularly highlighting latest modifications in the materials used for the various components .Multiple elementary reaction pathways are possible at each electrode during the operation of the Polymer fuel cell and many interrelated and complex phenomena occur. The following article is a review of the detailed analysis of each component of the Polymer Electrolyte membrane fuel cell particularly highlighting latest modifications in the materials used for the various components.Keywords

A major challenge for us in the 21st century is the transition from fossil-fuel-based energy to renewable energy. The growing world energy demand has urged people to search for new alternatives to conventional fossil resources. The earth's surface is encountered with approximately 40,000 exajoules (EJ) of solar energy annually. As the available resources are being exhausted and are harmful for the environment, there is a need for resources that are green, inexpensive, efficient and environment-friendly is increasing day by day. Today's solar cells are not efficient and are currently too expensive to manufacture for electricity generation. Cost is an important factor in solar technology. However, recent advancements in nanotechnology may open the door for the production of cheaper and slightly more efficient solar cells.. Nanotechnology has already shown some huge breakthroughs in the solar field. Nanotechnology might be able to increase the efficiency of solar cells by broadening the absorption spectrum and reduce the cost of production. Utilizing nanotechnology in an inexpensive solar cell would help to overcome cost and efficiency problems. This paper provides an overview of the absorption of solar power in the infrared spectrum by using nanomaterials in organic photovoltaics. Application of nanotechnology in these organic photovoltaics will help us to make solar energy more economical and efficient making energy production environmental-friendly.Keywords

Renewable energy is the need of the day to address energy crisis in the world. Renewable energy share in India is nearly 14% of the total installed capacity. Ocean energy does not contribute to this share at all. With a long coast line ocean energy has enormous potential of electricity generation in India especially for remote coastal areas which are still deprived of electricity. Although India is blessed with large amount of solar power, but during south west monsoon months, western coast of India experiences rainy season for around three to four months i.e. from June to September. Wave energy potential increases during monsoon months, which is evident from considerable increase in significant wave height and mean wave period. A hybrid arrangement with wave energy and solar energy generation using stand alone micro-grids can solve the problem of energy deficit and can also supply households of remote coastal areas of India that have no electricity.
This paper describes potential of wave energy along western coast of India. With significant wave height and mean wave period data obtained from wave rider buoys and moored buoys installed along various locations of western coast of India, an assessment of wave energy has been obtained. With solar irradiation data along the coast it is established that solar and wave energy hybrid system can be an answer to the problem of remote coastal areas deprived of grid connection.
