Abstract The building blocks of Titan and Enceladus are believed to have formed in a late-stage circumplanetary disk (CPD) around Saturn. Evaluating the evolution abundances volatile species this as function migration, growth, evaporation icy grains is then primary importance assess origin material that eventually these two moons. Here we use simple prescription Saturn’s CPD which location cent...

The Belt Purcell Supergroup rocks extend from the Western United States into Southern British Columbia and Alberta. Soft sediment carbonate vein networks occur within various formations of the Belt Purcell rocks. These vein networks outcrop in various localities, however, this paper is limited to a description of the outcrops of the Kitchener Formation, west of Moyie Lake (Figure 1) in Southeas...

We use the clathrate hydrate trapping theory (Lunine & Stevenson 1985) and the gas drag formalism of Weidenschilling (1977) to calculate the composition of ices incorporated in the interior of Ceres. In the spirit of the work of Cyr et al. (1998), and using a time dependent solar nebula model, we show that icy solids can drift from beyond 5 AU to the present location of the asteroid and be pres...

Introduction: The composition of the martian polar caps has long been debated with a consensus opinion that the north is composed predominately of water ice and the south a combination of solid CO2 and water ice [1]. Smythe and Miller [2] suggested that the polar caps may be composed of at least some CO2 hydrate, aka. clathrate, or compound gas hydrates [3, 4, 5, 6, 7]. Durham [8] predicted tha...

Clathrate hydrates are emerging as a novel storage medium for safe and compact methane storage. However, their industrial-scale applicability is hindered by relatively lower gas uptake sluggish formation kinetics. In this study, we have employed zeolites with acidic (H–Y, FAU-type) basic (Na–X, surface properties kinetic hydrate promoters (KHPs). The impact of physical parameters pressure the g...

We have studied the diffusive mobility of hydrogen molecules confined in different size cages in clathrate hydrates. In clathrate hydrate H2 molecules are effectively stored by confinement in two different size cages of the nano-porous host structure with accessible volumes of about 0.50 and 0.67 nm diameters, respectively. For the processes of sorption and desorption of the stored hydrogen the...
