Journées “Hydrates” Journées Hydrates, Brest, 09‐13 septembre 2019 Journées “Hydrates” 09‐13 septembre 2019 IFREMER Pôle Numérique 305 Avenue Alexis de Rochon 29280 PLOUZANE 1 Journées Hydrates, Brest, 09‐13 septembre 2019 2 Journées Hydrates, Brest, 09‐13 septembre 2019 WELCOME We are pleased to welcome you for the 2nd meeting of the French research consortium GdR2026 Hydrates at the University of Bordeaux. This event brings together leading experimental, theoretical, and computational scientists from among the unusually broad community of researchers interested in the various research areas of gas hydrates going from chemical and energy engineering to geosciences and astrophysics through physical‐ chemistry and thermodynamics. The issues addressed during this meeting concern major aspects of “hydrate sciences” such as hydrate/substrates interactions, thermodynamics, formation kinetics, cage occupancy and as well as formation at extreme conditions. The workshop is divided into two parts. The first part is dedicated to meetings of french research consortiums working on a common project (ANR, EU, etc.) in closed session. The second part is the general meeting, gathering about 60 participants. Its scientific program contains about 31 presentations, including invited talks, oral contributions and poster presentations.

  • Mechanical Characterization Via Full Atomistic Simulation: Applications to Nanocrystallized Ice
    Mechanical Characterization via Full Atomistic Simulation: Applications to Nanocrystallized Ice A thesis presented By Arvand M.H. Navabi to The Department of Civil and Environmental Engineering in partial fulfillment of the requirements for the degree of Master of Science in the field of Civil Engineering Northeastern University Boston, Massachusetts August, 2016 Submitted to Prof. Steven W. Cranford Acknowledgements I acknowledge generous support from my thesis advisor Dr. Steven W. Cranford whose encouragement and availability was crucial to this thesis and also my parents for allowing me to realize my own potential. The simulations were made possible by LAMMPS open source program. Visualization has been carried out using the VMD visualization package. 3 Abstract This work employs molecular dynamic (MD) approaches to characterize the mechanical properties of nanocrystalline materials via a full atomistic simulation using the ab initio derived ReaxFF potential. Herein, we demonstrate methods to efficiently simulate key mechanical properties (ultimate strength, stiffness, etc.) in a timely and computationally inexpensive manner. As an illustrative example, the work implements the described methodology to perform full atomistic simulation on ice as a material platform, which — due to its complex behavior and phase transitions upon pressure, heat exchange, energy transfer etc. — has long been avoided or it has been unsuccessful to ascertain its mechanical properties from a molecular perspective. This study will in detail explain full atomistic MD methods and the particulars required to correctly simulate crystalline material systems. Tools such as the ReaxFF potential and open-source software package LAMMPS will be described alongside their fundamental theories and suggested input methods to simulate further materials, encompassing both periodic and finite crystalline models.

  • The Origin of Titan's Atmosphere: Some Recent Advances
    The origin of Titan’s atmosphere: some recent advances By Tobias Owen1 & H. B. Niemann2 1University of Hawaii, Institute for Astronomy, 2680 Woodlawn Drive, Honolulu, HI 96822, USA 2Laboratory for Atmospheres, Goddard Space Fight Center, Greenbelt, MD 20771, USA It is possible to make a consistent story for the origin of Titan’s atmosphere starting with the birth of Titan in the Saturn subnebula. If we use comet nuclei as a model, Titan’s nitrogen and methane could easily have been delivered by the ice that makes up ∼50% of its mass. If Titan’s atmospheric hydrogen is derived from that ice, it is possible that Titan and comet nuclei are in fact made of the same protosolar ice. The noble gas abundances are consistent with relative abundances found in the atmospheres of Mars and Earth, the sun, and the meteorites. Keywords: Origin, atmosphere, composition, noble gases, deuterium 1. Introduction In this note, we will assume that Titan originated in Saturn’s subnebula as a result of the accretion of icy planetesimals: particles and larger lumps made of ice and rock. Alibert & Mousis (2007) reached this same point of view using an evolutionary, turbulent model of Saturn’s subnebula. They found that planetesimals made in the solar nebula according to their model led to a huge overabundance of CO on Titan. We obviously have no direct measurements of the composition of these planetes- imals. We can use comets as a guide, always remembering that comets formed in the solar nebula where conditions must have been different from those in Saturn’s subnebula, e.g., much colder.

  • Formation of Clathrate Hydrate from Amorphous Ice During Warming R
    Formation of clathrate hydrate from amorphous ice during warming R. Netsu, T. Ikeda-Fukazawa Department of Applied Chemistry, Meiji University, Japan Water molecules are condensed on dust grains in interstellar molecular clouds and protester nebulae. The water exists as amorphous ice in the cold clouds and is transformed into various structures depending on thermal conditions and compositions with various deposited molecules. Blake et al. [1] proposed the presence of CO2 clathrate hydrate in cometary ice. From the results using the transmission electron microscopy (TEM) and fourier transformed infrared spectroscopy (FT-IR), they showed the phase transition of vapor deposited amorphous ice including CO2 and CH3OH into type-II clathrate hydrate at around 120 K. Clathrate hydrates are inclusion compounds consisting of water molecules and a variety of guests molecules. Most clathrate hydrates form one of two distinct crystallographic structures, type-I and –II, depending on the sizes and shapes of the guest molecules. The cubic unit cell of type-I clathrate hydrate contains 46 water molecules in a framework of two dodecahedral and six tetrakaidecahedral cages, and that of type-II clathrate hydrate contains 136 water molecules in a framework of 16 dodecahedral and eight hexakaidecahedral cages. The structure of CO2 clathrate hydrate formed under a high pressure condition is type-I [2]. For the hydrate from the vapor deposited amorphous ice [1], the structure is type-II due to the help-gasses effect of CH3OH. For the CO2 clathrate hydrate grown epitaxially on a hydrate in low pressure conditions, the structure depends on the structure of the hydrate as the substrate [3].

  • Effects of Additives on the Formation of Methane and Carbon Dioxide Gas Hydrates
    Effects of Additives on the Formation of Methane and Carbon Dioxide Gas Hydrates Nguyen Ngoc Nguyen B.E. & M.Sc. of Chemical Engineering A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2017 School of Chemical Engineering Abstract Gas hydrates (GHs) are ice-like crystalline solids comprising water and suitable gases in which gas molecules are physically encaged in a cage-like hydrogen-bonded structure formed by water molecules. Under the presence of appropriate additives, the formation of GHs can be controlled in a desired manner thereby opening novel ways of using GHs for gas storage and transportation, carbon dioxide sequestration, gas separation, desalination, etc. Although significant works have been undertaken to investigate the effects of additives on gas hydrate formation, there still remains a substantial gap in the understanding of the fundamentals behind the experimental observations. This thesis aims to provide new molecular insights into the effects of surfactants, hydrophobic solid surfaces and sodium halides on the formation of GHs. These effects are studied at the molecular level using synergic combinations of experimental and computational techniques. Kinetics experiments using a high-pressure reactor are carried out to quantify the effect of additives on the kinetics of gas enclathration. A see-through reactor is used for in situ visual observations of the effects of the hydrophobicity of solid surfaces on the formability of GHs. Interface-susceptible sum frequency generation (SFG) vibrational spectroscopy is employed to analyse water structure at gas- solution interfaces. Attenuated total reflectance Fourier transform infrared (ATR-FTIR) is employed to analyse water structure in the bulk solution.

This ramp extended from the northwest margin of Laurentia into the open waters of the ancestral Pacific Ocean to the north. The mound developed in an outer ramp environment, in relatively deep and cold water. A steep northern margin with a slope that exceeds 55' characterizes the mound.
