Enhancement of the Rate of Surface Reactions by Elasto-capillary Effect
Nitish Singh, Animangsu Ghatak
Rate of a reaction is enhanced by increase in temperature, partial pressure or the concentration of reactants, and/or via use of a catalyst or an enzyme. Whereas the former increas…
Hierarchically Rough Surface used as Rewritable and Reprintable paper
Nitish Singh, Animangsu Ghatak
We describe here the design and fabrication of a rewritable and reprintable paper as an alternative to conventional papers which are generally used for writing and printing purpose…
Rolling of an elastomeric cylinder: a Marangoni like effect in solid
Subrata Mondal, Animangsu Ghatak
A soft, thin, elastomeric micro-cylinder is induced to roll on a solid substrate by releasing small quantity of a solvent. The solvent swells the cylinder asymmetrically at one sid…
How to make a cylinder roll uphill
Dipabali Hore, Abhijit Majumder, Subrata Mondal +2
Slithering, crawling, slipping, gliding are various modes of limbless locomotion that have been mimicked for micro-manipulation of soft, slender and sessile objects. A lesser known…
Disordered nano-wrinkle substrates for inducing crystallization over a wide range of concentration of protein and precipitant
Anindita Sengupta Ghatak, Animangsu Ghatak
There are large number of proteins, the existence of which are known but not their crystal structure, because of difficulty in finding the exact condition for their crystallization…
Adhesion Induced Instabilities and Pattern Formation in Thin Films of Elastomers and Gels
Manoj K. Chaudhury, Aditi Chakrabarti, Animangsu Ghatak
A hydrostatically stressed soft elastic film circumvents the imposed constraint by undergoing a morphological instability, the wavelength of which is dictated by the minimization o…
