Self-propelling active particles are an exciting and interdisciplinary emerging area of research with projected biomedical and environmental applications. Due to their autonomous m…
Electrokinetic Power Harvesting from Wet Textile
Sankha Shuvra Das, Vinay Manaswi Pedireddi, Aditya Bandopadhyay +2
Developing low-weight, frugal and sustainable power sources for resource-limited settings appears to be a challenging proposition for the advancement of next-generation sensing dev…
Energy-Efficient Micromixing in Paper Based Devices Mediated by the Interplay of Electrical and Thermal Fields
Golak Kunti, Sankha Shuvra Das, Vinay Manaswi Pedireddi +2
Biomedical and biochemical processes in paper-based microfluidic devices often deal with mixing of two analytes to perform important functions. Uniform mixing of analytes in paper…
Anomalous diffusion in an electrolyte saturated paper matrix
Sankha Shuvra Das, Sumeet Kumar, Sambuddha Ghosal +2
Diffusion of colored dye on water saturated paper substrates has been traditionally exploited with great skill by renowned water color artists. The same physics finds more recent p…
Controlled Electrokinetic Particle Manipulation using Paper-and-Pencil Microfluidics
Sankha Shuvra Das, Shantimoy Kar, Sayantan Dawn +2
Dielectrophoresis is a very promising technique for particle manipulation on a chip. In this study, we demonstrate a controlled mannuvering of polystryrene particles on a simple pa…
Pitcher Plant Inspired Biomimetic Liquid Infused Slippery Surface Using Taro Leaf
Rahul Sharma, Sankha Shuvra Das, Udita Uday Ghosh +2
Bio-inspired anti-wetting surfaces, such as lotus leaf or pitcher plant, have led to the development of stable liquid infused slippery surfaces for various scientific applications.…
Excimer laser cleaning of black sulphur encrustation from silver surface
Mohammad Shahid Raza, Sankha Shuvra Das, Parimal Tudu +1
The process of localized cleaning of silver sulphide from the silver surface has been investigated in this work. An artificial black encrustation was generated on the silver surfac…
Surfactant-induced-retardation in lateral migration of droplets in a microfluidic confinement
Somnath Santra, Sayan Das, Sankha Shuvra Das +1
In the present study, the role of surfactants on the cross-stream migration of droplets is investigated both experimentally and theoretically. For experimental analysis, sunflower…
Electrokinetic Energy Harvesting using Paper and Pencil
Sankha Shuvra Das, Shantimoy Kar, Tarique Anwar +2
We exploit the combinatorial advantage of electrokinetics and tortutosity of cellulose-based paper network on a laboratory grade filter paper for the development of a simple, inexp…
