Thermoacoustic engines convert thermal energy, conceivably at relatively low temperatures, to mechanical energy in the form of high-amplitude acoustic oscillations. The thermoacoustic engine, a potential green technology ...

Energy storage via the combination of hydrogen production and fuel cell has been a very active field of research for the last few decades. Nanostructured semiconductor materials are now being utilized for hydrogen production ...

Fire incidents in densely populated urban areas can rapidly results in a catastrophicmulti-death scenario, in absence of adequate fire-fighting equipment. As smoke generatedduring fire hazards is predominantly responsible ...
