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…
Curvilinear polyhedra as dynamical arenas, illustrated by an example of self-organized locomotion
Shankar Ghosh, A. P. Merin, S. Bhattacharya +1
Experiment shows that dumbbells, placed inside a tilted hollow cylindrical drum that rotates slowly around its axis, climb uphill by forming dynamically stable pairs, seemingly aga…
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…
