In this paper, we conduct Molecular Dynamics Simulations and provide a scaling theory for probing the shearing and lubrication action in weakly interpenetrated polymer brush bilayers. This is Parth’s 4th paper from the group. Congrats Parth !!!!

The title of the thesis was “ENERGY CONVERSION IN NANOCHANNELS GRAFTED WITH POLYELECTROLYTE AND POLYZWITTERION BRUSHES”….Congrats Jahin !!!!!

SMIEL PhD student has been awarded the prestigious STLE (Society of Tribologists and Lubrication Engineers) Scholarship. Congrats Parth !!!!!  

Prof. Siddhartha Das has been awarded the IIT Kharagpur inaugural Young Alumni Achievers Award (YAAA) for successful IITKGP alumni under 40 years. The announcement can be found in this link

In this paper, we describe theoretically a most remarkable situation where end-charged polyelectrolyte brushes significantly enhance the diffusioosmotic transport in nanochannels by localizing the electric double layer charge density away from the channel walls…this is Raja’s first paper, Harnoor’s 6th, and Haoyuan 8th paper from the group. A BIG congratulations to all of them !!!!!

Prof. Das delivers an invited talk titled “Modeling Transport in Microfluidic Systems: Towards Better Equipping Ourselves for Solving Biomedical Engineering Problems” at US Food and Drug Administration

In our 2015 Nature Communication paper, we have provided a force-based argument  to explain the drop motion. A recent paper in PNAS claimed our theory to be flawed on the basis of an energy-dissipation-based argument. In this paper, which is a Letter to the Editor, we showed that the claim of this PNAS paper was

In this paper, we propose a new design where biomimetic nanoparticles (NPs) use electrostatic interactions to simultaneously promote specific adhesion and prevent non-specific adhesion to plasma membranes.

In this paper, we study the force-driven translocation of a water nanodrop through a holey graphene matrix demonstrating a capillarity-mediated breakdown of Darcy’s Law.

In this paper, we show that in nanochannels functionalized with end-charged polyelectrolyte brushes one can significantly augment the efficiency of the electrokinetic energy conversion.
