The three-dimensional (3D) fabric in natural sensitive clay is quantified from a combination of high resolution nano and microtomographies, scanning electron microscopy, dynamic light scattering. Although the speckle arising particles pores they enclose discerned nanotomography data compare well with microscopy (SEM) images on same clay, individual platelet-shaped cannot be segmented for subseq...

Precise structural studies of nano-crystalline minerals using diffraction techniques have been hindered by the broad diffraction peaks found in their diffraction patterns. In this thesis, I have applied molecular scale techniques such as High-Energy X-ray Diffraction and Molecular Dynamics simulations to study the structure and reactivity of two nano-minerals of important environmental signific...

This study investigates the nano to core-scale geomechanical properties of a maturity series organic-rich, calcareous shales buried 100°C–180°C, with focus on: (a) mechanical organic matter; (b) elastic response and anisotropy shale composite at micro core scale; (c) creep response. Atomic force microscopy was used target kerogen nanoscale resolution, it found that stiffness increased thermal f...

Abstract Polytetrafluoroethylene (PTFE) polymer is used extensively in industry as a solid lubricant because of its lack reactivity with most industrial materials. However, PTFE has low abrasive resistance, limiting application. In this study, the mechanical and tribological characteristics PTFE-based composites addition clay nano-sheets (CNSs) were investigated. Clay nano-sheet-PTFE (CNSTCs) c...
