We studied experimentally the dissolution of a porous limestone core during CO 2 ‐enriched water injection. measured changes in porosity and permeability arising from modifications pore network geometry fluid‐rock interface. A methodology based on periodic X‐ray microtomography imaging was implemented to record evolution time‐ scale‐dependent microstructures with spatial resolution 4.91 μm. Two processes were successively involved rapid increase sample, as documented microscale core‐scale...
Indenter experiments have been performed on quartz crystals in order to establish a pressure solution creep law relevant at upper middle crustal conditions. This deformation mechanism contributes Earth's crust geodynamics, controlling processes as different fault permeability, strength, and stress evolution during interseismic periods or mechanochemical differentiation diagenesis metamorphism. 350°C 20–120 MPa months with differential varying from 25 350 MPa. Several experimental parameters...
Additive manufacturing of oxide glass enables on-demand, low-cost complex optical components for numerous applications, opening new opportunities to explore functionalities inaccessible otherwise. Here, we report a straightforward extrusion-based 3D-printing approach, deploying the fused deposition modeling (FDM) process, produce optically transparent phosphate glasses with geometries and preserved structural photoluminescence properties. Using customized entry-level FDM desktop printer...
A reactive flow-through experiment by carbon dioxide-saturated water at the partial pressure of 0.1 MPa and room temperature was conducted on a porous limestone in order to identify relationships between fluid chemistry, hydrodynamics structural properties. Periodic imaging non destructive X-ray microtomography allowed following evolution core micro-geometry fluid-rock interface detail while its porosity permeability increased due dissolution. Several mechanisms were successively involved...
In order to investigate on the pore scale mechanisms involved during CO<sub>2</sub> injection in a water saturated network, series of displacement experiments is reported using high pressure micromodels (geological labs chip – GloCs) working under real geological conditions (25 < <italic>T</italic> (°C) 75 and 4.5 <italic>p</italic> (MPa) 8).
Pressure solution creep is one of the possible processes mechano‐chemical deformation that controls porosity and permeability variations in upper crust. The three‐dimensional geometry porous network halite aggregates was imaged during compaction driven by pressure using X‐ray synchrotron computed microtomography. This technique can be used to monitor individual grain contacts whole aggregate textural changes deformation. By reconstructing subvolumes, 3D extracted. time‐resolved decrease...
Abstract Several compounds with the pyrochlore structure have been investigated. Dielectric and structural studies of compound Cd2NB2O6S show existence three phase transitions at 106°C, 184°C 282°C. The ferroelectric properties studied by several methods (x-Ray, DTA, dielectric dilatometric methods, second harmonic generation). We also discuss some hypotheses. Bi2MIIIMvO7, oxides (MIII=Cr, Fe, In, Sc; Mv=Nb, Ta, Sb) cubic prepared. Some exhibit broad maxima in temperature dependence constant...

The Messinian microbialites of the Terminal Carbonate Complex (TCC) from Neogene basins southeastern Spain show both diversified morphologies and an excellent preservation primary microbial microstructures. Their stratigraphic architecture, fabric (micro-, meso-, macro-fabric), mineralogical composition were investigated in eight localities three sedimentary Spain: Sorbas Bajo Segura Agua Amarga depression. Two recurrent microbialite associations distinguished. Laterally linked low relief...
