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.

The thesis topic was “BILAYER MEMBRANE ELECTROSTATICS AND CHARGE-REGULATED MEMBRANE NANOPARTICLE INTERACTIONS”. Shayandev is 2nd PhD to graduate from SMIEL…many congratulations Shayandev

The topic of the thesis was “ENHANCED DIFFUSIOOSMOSIS AND THERMOOSMOSIS IN POLYELECTROLYTE-BRUSH-FUNCTIONALIZED NANOCHANNELS”. This is the second MS from SMIEL…Many congratulations Raja….

Prof. Siddhartha Das delivered an invited talk titled “Water and Ions at Nanoscopic Interfaces: From 2-D materials to plasma membranes” at the Waterloo Institute of Nanotechnology (WIN) of the University of Waterloo.

News story on the PRE article on the simulation and scaling theory of weakly interpenetrated polyelectrolyte brushes has been published on the UMD Mechanical Engineering website (link) and the A. James Clark School of Engineering Website (link).

In this paper, we propose how surface charges on plasma membranes can favor non-specific adhesion of Nanoparticles to stiffer plasma membranes….This is Shayandev’s 19th paper, Haoyuan’s 7th paper, and Harnoor’s 2nd paper from the group. Congrats to all three of them !!!!

In this paper, we develop a new theory to probe the overspray effect in Aerosol Jet 3D Printing. This is Guang’s 18th paper and Yuan’s 3rd paper form the group. Congratulations to both !!!!!!
