We aimed to investigate the effect of morin hydrate on neural stem cells (NSCs) isolated from mouse inner ear and its potential in protecting neuronal hearing loss. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and bromodeoxyuridine incorporation assays were employed to assess the effect of morin hydrate on the viability and proliferation of in vitro NSC culture. The N...

Large quantities of methane hydrate are present in marine sediment. When methane hydrate is exposed or released to seawater, it dissolves in seawater or dissociates into methane gas and water. There was some confusion in the literature about the kinetics of these processes. It is critical to realize that dissolution and dissociation are two different processes. Dissolution is due to instability...

As the foundation of energy industry moves towards gas, flow assurance technology preventing pipelines from hydrate blockages becomes increasingly significant. However, the principle of hydrate inhibition is still poorly understood. Here, we examined natural hydrophobic amino acids as novel kinetic hydrate inhibitors (KHIs), and investigated hydrate inhibition phenomena by using them as a model...

Direct measurements of the dissociation behaviors of pure methane and ethane hydrates trapped in sintered tetrahydrofuran hydrate through a temperature ramping method showed that the tetrahydrofuran hydrate controls dissociation of the gas hydrates under thermodynamic instability at temperatures above the melting point of ice.

We are focusing on the practical use of methane hydrate. For recovery and it as an energy resource, is necessary to consider possibility clogging in pipe due rehydration bubbles. The purpose this research was observe experimentally evaluate theoretically decomposition behavior hydrate sedimentary layer rising bubbles generated by decomposition. Chlorodifluoromethane used a low pressure model ga...

Predicting the Hydrate Stability Zones of Natural Gases Using Artificial Neural Networks — A feed-forward artificial neural network with 19 input variables (temperature, gas hydrate structure, gas composition and inhibitor concentration in aqueous phase) and 35 neurons in single hidden layer has been developed for estimating hydrate dissociation pressures of natural gases in the presence/absenc...

In this work, constant pressure Gibbs ensemble Monte Carlo (GEMC) simulations were applied as an alternative to grand canonical Monte Carlo (GCMC) simulations to calculate gas hydrate occupancy as function of temperature and pressure. Both rigid and flexible hydrate lattice models were investigated. GEMC structure I methane hydrate occupancy results using the flexible lattice model agree with e...

Natural gas hydrate reservoir has been identified as a new alternative energy resource which characteristics of weak cementation, low strength and shallow overburden depth. Thus, the stability subsea equipment formation can be affected during drilling process. To quantitatively assess vertical displacement induced by decomposition clearly identify influence laws various factors on wellhead stab...

Methane hydrate applications in gas storage and desalination have attracted increasing attention recent years. In the present work, effect of isopentane (IP), sodium dodecyl sulfate (SDS), IP/SDS blends as promoters on methane formation kinetics, terms pressure–temperature (P-T) profile, uptake, induction time (HIT), water-to-hydrate conversion ratio (WHCR), were studied for distilled water sea...

The effective thermal conductivity of the powder samples of xenon hydrate was measured in the interval 2–170 K using the steady-state method. The thermal conductivity of the homogeneous Xe clathrate hydrate was estimated from the effective thermal conductivity using an empirical expression. The applicability of the formula was checked by comparing two powder samples with different grain size an...
