Evolution of polygonal crack patterns in mud when subjected to repeated wetting-drying cycles
Ruhul A I Haque, Atish J. Mitra, Sujata Tarafdar +1
The present paper demonstrates how a natural crack mosaic resembling a random tessellation evolves with repeated 'wetting followed by drying' cycles. The natural system here is a c…
Pattern formation in desiccated sessile colloidal droplets with salt admixture: Short review
Yuri Yu. Tarasevich, Sujata Tarafdar, Tapati Dutta
This short review is devoted to the simple process of drying a multi-component droplet consisting of a complex fluid containing a salt. These processes provide a fascinating subjec…
Relation between Lacunarity, Correlation dimension and Euclidean dimension of Systems
Abhra Giri, Sujata Tarafdar, Tapati Dutta
Lacunarity is a measure often used to quantify the lack of translational invariance present in fractals and multifractal systems. The generalised dimensions, specially the first th…
Growth kinetics of NaCl crystals in a drying drop of gelatin: transition from faceted to dendritic growth
Moutushi Dutta Choudhury, Tapati Dutta, Sujata Tarafdar
We report a study on the kinetics of drying of a droplet of aqueous gelatin containing sodium chloride. The process of drying recorded on video, clearly shows different regimes of…
Multi-scale Patterns formed by Sodium Sulphate in a Drying Droplet of Gelatin
Biswajit Roy, Moutushi Dutta Choudhuri, Tapati Dutta +1
We present a study of patterns, formed in drying drops of aqueous gelatin solution containing sodium sulphate. The patterns are highly complex, consisting of a hierarchical sequenc…
Squeeze flow of potato starch gel: effect of loading history on visco-elastic properties
Moutushi Dutta Choudhury, Shantanu Das, Sujata Tarafdar
In this work gelatinized potato starch is shown to retain the memory of past loading history. It exhibits a visco-elastic response which does not depend solely on instantaneous con…
