In-situ-SANS Investigations of C5F12 Condensation in Mesoporous Silicas with a Hierarchical Pore Structure
1. Introduction The condensation of liquids from the gas phase and the pore emptying mechanism in mesoporous frameworks (pore size 2 – 50 nm) represents an important scientific issue owing both to the significant industrial relevance (catalysis, separation process, etc.), but also to its importance for the fundamental understanding of the behavior of fluids in confined space. In general, the fi...
متن کاملCharacterization of Rock Pore Features in Geothermal Systems Using Small Angle Neutron Scattering (sans)
Enhanced Geothermal Systems (EGS) are engineered reservoirs created to economically extract heat from low permeability and/or porosity geothermal resources. Existing geochemical reactive transport models for such systems lack essential data on the structure of the pore systems in geothermal reservoirs, and how they evolve in the relevant ranges of temperature, pressure, composition, and length ...
متن کاملGeotextile Pore Structure Characterization Using Image Analysis
Filtration performance of geotextiles strongly depends on their pore structure parameters, i.e. percent open area (POA), pore opening size distribution (PSD) and constriction size distribution (CSD). Current methods of determination of pore structure parameters contain inherent disadvantages whereas image analysis can be used effectively for this purpose. Two new image-based PSD and CSD determi...
متن کاملSynthesis of gold nanoparticles: a new approach in using a nanoporous membrane in conjunction with ultrasonication
Gold nanoparticles were synthesized by chemical reduction of HAuCl4 inside the pores of a polycarbonate-based membrane followed by dissolving the membrane in dichloromethane and further sonication. Sonication time as the main affecting factor on the nanoparticle size was investigated. The characterization by transmission electron microscopy showed the formation of gold nanoparticles with diamet...
