The spatially distributed microstructures needed to implement many functionally graded material (FGM) designs are difficult to realize affordably with today's materials synthesis/processing technologies. To address this need, a new directed vapor deposition (DVD) technique has been developed and explored as a potential FGM synthesis tool. The technique exploits supersonic helium jets in combina...

Abstract Adsorption phenomena are encountered in several engineering applications. One of its uses is the storage and transport gas form adsorption tanks. The exothermic nature process decreases capacity presenting an impetus to understand thermal characteristics process. Studies using mixtures phase change materials adsorbents tanks demonstrate potential improvements They also show that distri...
