Analysis of edge and screw dislocation in complex layered oxide materials. While the mechanism of defect, dislocations and dislocation cores are well studies for simple crystalline materials such as BCC or FCC crystals, there is very limited knowledge on such mechanisms in complex layered oxides and their influence on the mechanical properties. Here, we are interested to study the mechanisms of screw and edge dislocation in tobermorite, as a complex, layered oxide material that is a crystalline analog of Calcium-Silicate-Hydrate (C-S-H).

Atomistic mechanisms govern nanoscale friction and instability in cement hydrate image. Calcium-Silicate hydrate (C-S-H) gel is the primary binding phase in cement paste and the main source of mechanical properties in concrete.

From electrons to concrete infrastructures: A paradigm shift in turning a traditional material to an advanced composite.

Hexagonal Boron Nitride and Graphene Oxide Reinforced Multifunctional Porous Cement Composites. We are interested in fundamental undemanding and characterization of multifunctional cement composites filled with hexagonal boron nitride (h-BN) and graphite oxide (GO).

Hydrogen bond mediated load transfer in hybrid organic-inorganic materials. By combining platelet-like ceramic building blocks and organic matrices, nature creates hybrid materials such as bone, teeth and mollusk shells that have outstanding balance of stiffness, strength and flaw-tolerance.

Investigating the behavior of fractional viscoelastic materials. Fractional calculus is an old mathematical topic; yet, its application in physics and engineering is more recent.

Mechano and thermo-mutable anisotropy of a multifunctional, porous 3D nanostructure: simulation and 3D printing. One-dimensional (1D) Boron Nitride nanotube (BNNT) and 2D hexagonal BN (h-BN) are attractive for demonstrating fundamental physics and promising applications in nano/microscale devices.
