Clathrate hydrogen hydrate--a promising material for hydrogen storage.
Hydrogen is viewed as a promising clean fuel of the future. A low-cost hydrogen storage technology that provides a high storage capacity and fast kinetics is a critical factor in the development of a hydrogen economy for transportation. The technologies to store hydrogen can be classified into three types: compression, liquefaction, and storage in a solid material. 2] Compressing hydrogen requi...
متن کاملSpectroscopic identification, thermodynamic stability and molecular composition of hydrogen and 1,4-dioxane binary clathrate hydrate
We present the spectroscopic identification of the binary hydrogen and 1,4-dioxane clathrate hydrates in which H2 molecules are encapsulated in small cages of the structure II hydrate framework. X-ray diffraction, solid-state NMR and Raman spectroscopy were used to confirm the mixed hydrate structure and more importantly the occupancy pattern of hydrogen in clathrate cages. The corresponding pr...
متن کاملRattling ‘‘guest’’ impurities in Si and Ge clathrate semiconductors
In addition to their ground state, diamond structure, Si, Ge and Sn can form crystalline solids called clathrates. As in the diamond structure, in the clathrates, the Group IV atoms are tetrahedrally coordinated and sp covalently bonded to their neighbors. However, the clathrates contain pentagonal atomic rings and have open-framework lattices containing 20-, 24and 28-atom ‘‘cages’’. There are ...
متن کاملHydrate-phobic surfaces: fundamental studies in clathrate hydrate adhesion reduction.
Clathrate hydrate formation and subsequent plugging of deep-sea oil and gas pipelines represent a significant bottleneck for deep-sea oil and gas operations. Current methods for hydrate mitigation are expensive and energy intensive, comprising chemical, thermal, or flow management techniques. In this paper, we present an alternate approach of using functionalized coatings to reduce hydrate adhe...
متن کاملNMR/MRI study of clathrate hydrate mechanisms.
Clathrate hydrates are of great importance in many aspects. However, hydrate formation and dissociation mechanisms, essential to all hydrate applications, are still not well understood due to the limitations of experimental techniques capable of providing dynamic and structural information on a molecular level. NMR has been shown to be a powerful tool to noninvasively measure molecular level dy...
