TL;DR: The synthesis of a three-dimensional macroassembly of graphene sheets with electrical conductivity and Young's modulus orders of magnitude higher than those previously reported, super-compressive deformation behavior, and surface areas approaching theoretically maximum values is reported.

TL;DR: The results show that distinct reaction zones form in response to reactions with the brine over the 8-day experiment, and detailed characterization of the crystalline and amorphous phases, and the solution chemistry show that the zones can be modeled as preferential portlandite dissolution in the depleted layer, concurrent calcium silicate hydrate alteration to anAmorphous zeolite and Ca-carbonate precipitation in the carbonate layer, and carbonate dissolve in the amorphou layer.

TL;DR: In this article, the authors describe how these geochemical and geomechanical processes affect fracture permeability in wellbore cement and compare these competing influences in light of data from a core-flood experiment conducted under carbon sequestration conditions.

TL;DR: In this article, the substitutions in a natural well-crystallized carbonate-containing apatite (CaF) were studied using infrared and solid-state nuclear magnetic resonance (NMR) spectroscopic techniques.

TL;DR: In this article, carbonated brine was introduced into artificial fractures separating wellbore-cement and tight-sandstone half-cores, and the propagation of the resulting reaction zones affected the hydraulic aperture of the core flood samples, and these changes are related to the fracture geometry.
