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…
Memory of rheological stress in polymers using Fractional Calculus
Archishna Bhattacharyya, Pratyusha Nandi, Somasri Hazra +1
The rheological properties of viscoelastic materials like polymer melts are greatly affected by factors like salinity, temperature, concentration and pH of the solution. In this st…
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…
