Journal ArticleDOI
Transformation of Methane Hydrate to Carbon Dioxide Hydrate: In Situ Raman Spectroscopic Observations
TL;DR: In this paper, an in situ Raman spectroscopy study on the guest replacement of methane hydrate with carbon dioxide at high pressures is presented, showing that the surface shielding of carbon dioxide hydrate formed in the outer layer plays a key function, retarding dissociation of methane in the core.
Journal ArticleDOI
Arsenic resistance and removal by marine and non-marine bacteria.
Mio Takeuchi,Hodaka Kawahata,Lallan P. Gupta,Noriko T. Kita,Yuichi Morishita,Yoshiro Ono,Takeshi Komai +6 more
TL;DR: Results showed that arsenic resistant and/or accumulating bacteria are widespread in the aquatic environment, and that arsenic-accumulating bacteria such as M. communis are potential candidates for bioremediation of arsenic contaminated water.
Journal ArticleDOI
Atmospheric polycyclic aromatic hydrocarbons: size distribution, estimation of their risk and their depositions to the human respiratory tract.
TL;DR: The results revealed that the same six PAHs identified using unit risk evaluation were large contributors in all five parts of the respiratory tracts in adult males in spite of deposition process.
Journal ArticleDOI
Characterization of sand sediment by pore size distribution and permeability using proton nuclear magnetic resonance measurement
Hideki Minagawa,Yasunori Nishikawa,Ikuko Ikeda,Kuniyuki Miyazaki,Naoya Takahara,Yasuhide Sakamoto,Takeshi Komai,Hideo Narita +7 more
TL;DR: In this paper, the pore size distribution and porosity of sediment with different grain size distributions were measured using proton nuclear magnetic resonance (NMR) and mercury porosimetry.
Journal ArticleDOI
Rigorous Approach to the Prediction of the Heat of Dissociation of Gas Hydrates
TL;DR: In this paper, the authors presented a theoretically correct method for predicting the heat of dissociation of gas hydrates using a fugacity-based model based on the Clausius−Clapeyron equation.
