Mechanics of a granular skin
Somnath Karmakar, Anit Sane, S. Bhattacharya +1
Magic Sand, a hydrophobic toy granular material, is widely used in popular science instructions because of its non-intuitive mechanical properties. A detailed study of the failure…
Rheology of hydrating cement paste: crossover between two aging processes
Atul Varshney, Smita Gohil, B. A. Chalke +4
The roles of applied strain and temperature on the hydration dynamics of cement paste are uncovered in the present study. We find that the system hardens over time through two diff…
Electric-field-induced turbulent energy cascade in an oil-in-oil emulsion
Atul Varshney, Mayur Sathe, Shankar Ghosh +3
We observe electro-hydrodynamically driven turbulent flows at low Reynolds numbers in a two-fluid emulsion consisting of micron-scale droplets. In the presence of electric fields,…
Spreading of triboelectrically charged granular matter
Deepak Kumar, A. Sane, Smita Gohil +3
We report on the spreading of triboelectrically charged glass particles on an oppositely charged surface of a plastic cylindrical container in the presence of a constant mechanical…
Transition of a particle between adjacent optical traps: A study using catastrophe theory
Deepak Kumar, Shankar Ghosh, S. Bhattacharya
In spite of the widespread use of optical tweezers as a quantitative tool to measure small forces, there exists no unambiguous and simple experimental method for either validating…
Dynamical instabilities of two-fluid interfaces in a porous medium: A three-dimensional video imaging study
Prerna Sharma, P. Aswathi, Anit Sane +2
Two-fluid interfaces in porous media, an example of driven disordered systems, were studied by a real time three-dimensional imaging technique with pore scale resolution for a less…
