The application of a temperature difference (∆T) across a solid conductor causes mobile charge carriers to diffuse from hot to cold regions, giving rise to a thermoelectric voltage ∆V=-Se. ∆T. The prefactor Se is called the thermopower or Seebeck coefficient which describes how electrical energy can be generated from the thermal energy. The great majority of today’s thermoelectric (TE) research...

Abstract Efficient storage of hydrogen is one the biggest challenges towards a potential economy. Hydrogen in liquid carriers an attractive alternative to compression or liquefaction at low temperatures. Liquid can be stored cost-effectively and transportation distribution integrated into existing infrastructures. The development efficient part work International Energy Agency Task 40: Hydrogen...

Energy supply is one of the main challenges of the present century. Population growth, rising energy demand, fossil fuel scarcity, and environmental concerns have made energy security as major issue for all countries in the world. Traditional power system, including low-efficiency generation, long-distance transmission and then a complex distribution system, face various challenges that make it...

the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...

Seawater reverse osmosis desalination (SWRO) requires less energy compared with the distillation method and thus is an important technology except Middle Eastern countries whereenergy costs are higher. Recently, even Middle Eastern countries where the distillation method is still a major technology, have begun adopting the RO method in new desalinationplants in line with government ...
