A well-testing model for partially perforated wells in natural gas hydrate reservoirs
Frontiers in Energy ResearchNatural gas hydrates (NGH) are considered a very promising source of clean energy due to their widespread distribution, high energy density, and pure combustion products.

Stability, Adsorption and Diffusion of CH4, CO2 and H2 in Clathrate Hydrates
, 2010 We present a study of the adsorption and diffusion of CH4, CO2 and H2 molecules in clathrate hydrates using ab initio van der Waals density functional formalism [Dion et al. Phys. Rev. Lett. 92, 246401 (2004)].

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Influence of Well Layout on Submarine Slope Stability during Natural Gas Hydrate Development
Journal of Marine Science and EngineeringThe exploitation of natural gas hydrates (NGHs) reduces the reservoir strength and increases the effective stress, which may trigger stratum settlement and submarine landslides. In particular, commercial-scale production requires the exploitation of NGHs

Procedia Engineering, 2016 AbstractThis paper presents new gas hydrate equilibrium data's for C2H6 (structure I) and CH4 + C3H8 (structure II) with and without the presence of sodium chloride. Macroscopic observation of gas hydrate dissociation under the presence of kinetic hydrate inhibitor (KHI) is also presented and compared with cells that have no inhibitor.

Magnetic Resonance Imaging of Gas Hydrate Formation and Conversion at Sub-Seafloor Conditions [PDF]
, 2013 The production of natural gas from sub-seafloor gas hydrates is one possible strategy to meet the world’s growing demand for energy. On the other hand, climate warming scenarios call for the substitution of fossil energy resources by sustainable energy

On the volatile enrichments and composition of Jupiter [PDF]
, 2005 Using the clathrate hydrates trapping theory, we discuss the enrichments in volatiles in the atmosphere of Jupiter measured by the \textit{Galileo} probe in the framework of new extended core-accretion planet formation models including migration and disk

Advanced Functional Materials, EarlyView.Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic
