Laser shock processing of polycrystalline diamond: experimental and numerical studies
Published 2024“…A correlation between the surface modification, microhardness and phase shifts in PCD was evident, thereby establishing a connection between phase transition, hardness and laser fluence.This thesis brings forth a multi-scale approach that is integrated with dry surface analyses for the characterisation of PCD composites before and after laser shock processing, combining atomic force microscopy (AFM) at nano scale. …”

Evaporation-driven self-assembly of binary and ternary colloidal polymer nanocomposites for abrasion resistant applications
Published 2020“…Through atomic force microscopy (AFM) and energy-dispersive X-ray spectroscopy (EDX), we show that the vertical distribution of filler particles and the surface morphologies of the films can be controlled by altering the evaporation rate and silica volume fraction. …”
