Sticking dynamics of deformable colloids
Prerna Sharma, Shankar Ghosh, S. Bhattacharya
The sticking of a soft polystyrene colloidal particle to a planar glass plate was studied by a microrheological technique using an optical tweezer to trap the particle and a piezoe…
Low temperature Raman study of Ca3Co2O6
Vinod panchal, Smita Gohil, Shankar Ghosh
We present low temperature Raman measurements on Ca3Co2O6. Shell model lattice dynamics calculations were done to determine the vibrational pattern of the expected Raman modes. In…
Non-monotonic size dependence of the elastic modulus of nanocrystalline ZnO embedded in a nanocrystalline silver matrix
Vinod Panchal, Shankar Ghosh, Smita Gohil +2
We present the first high pressure Raman study on nanocrystalline ZnO films with different average crystallite sizes. The problem of low Raman signals from nano sized particles was…
Motion of a sphere in an oscillatory boundary layer: an optical tweezer based study
Prerna Sharma, Shankar Ghosh, S. Bhattacharya
The drag forces acting on a single polystyrene sphere in the vicinity of an oscillating glass plate have been measured using an optical tweezer. The phase of the sphere is found to…
