Reliable characterization of the pore structure is essentially important for transport-related durability studies cementitious materials. Mercury intrusion porosimetry has been commonly used measurement while ink-bottle effect significantly affects trustworthiness size features Pressurization-depressurization cycling mercury (PDC-MIP) an alternative approach previously reported with purpose to ...

Herein it was found that CO(2) could trigger an O/W to W/O emulsion inversion via a W/O/W nanoemulsion. In comparison with the conventionally used liquid or solid additives, the unusual advantage of this method is that the emulsion morphologies can be switched reversibly by the control of CO(2) pressure. Besides, CO(2) can be easily removed by depressurization and thus no extra separation proce...

Despite being a widespread and common process, the impact of passive volcanic degassing on pressurization state magma reservoir is not well understood. If mass loss due to gas emissions results in depressurization surface subsidence, pressure difference between shallow deep source may result recharge eventually trigger an eruption. It therefore important determine how simplified reservoir-condu...

Karaha-Telaga Bodas is a recently discovered geothermal system located adjacent to Galunggung Volcano in western Java. Drilling to depths of 3 km has documented an extensive vapor-dominated zone and a deeper liquid reservoir with measured temperatures up to 350C and salinities of 1-2 weight percent. The vein parageneses record the evolution of a high temperature liquid-dominated system that dev...

Expansion energy is the main factor of coal and gas outbursts, desorption around outburst hole developed in variable pressure conditions. While studying impact moisture on characteristics, atmospheric usually used, but its characteristics under conditions have not been thoroughly investigated. In this study, typical samples with different water contents from Jincheng mining area China were sele...

BACKGROUND There is considerable interest in the conversion of lignocellulosic biomass to liquid fuels to provide substitutes for fossil fuels. Pretreatments, conducted to reduce biomass recalcitrance, usually remove at least some of the hemicellulose and/or lignin in cell walls. The hypothesis that led to this research was that reactor type could have a profound effect on the properties of pre...

A major technological barrier to achieving superior properties of nano-structured composite materials is the difficulty of dispersing fillers uniformly in a host matrix. The existing nanocomposite manufacturing processes achieve property improvements through chemical modifications of filler structures and utilization of chemical interactions between the chemically modified fillers and matrix po...

During 1997 and 1998, members of the Oak Ridge National Laboratory (ORNL) Radon Team installed 47 single-suction-point active soil depressurization (ASD) systems in 47 multiplex housing units located in 24 buildings in Guam. Subslab vacuum measurements performed within adjacent housing units found sufficient field extension to provide potential radon reduction within 39 additional units. Follow...
