The title of the talk was: “Diffusioosmotic and Thermoosmotic Transport in Nanochannels Grafted with End-Charged Polyelectrolyte Brushes – Continuum Calculations and Molecular Dynamics Simulations”

In this paper, we study the effect of excludedvolume interactions and modified form of the mass action law in the Strong Stretching Theory description of the Polyelectrolyte Brushes. This is Harnoor’s 9th paper and Vishal’s 1st paper from the group. Congrats both !!!!

Neil Dalal (co-advised by Prof. Abhijit Dasgupta and Prof. Siddhartha Das) successfully defends his MS thesis titled “INFLUENCE OF GAS FLOW RATES ON TRACE QUALITY AND RELIABILITY IN A SELECTED CONDUCTOR INK PRINTED WITH AN AEROSOL JET PRINTER”. Many congratulations, Neil !!!!!

In this collaborative work with the group of Prof. Liangbing Hu, we study the ionic conduction in Cellulose nanofluidic channels. My group’s contribution in this paper has been simulating the transport and quantifying the ionic conductivity. This is Guang’s 22nd paper from the group. Congrats Guang !!!!

In this paper, we study the generation of highly enhanced water-graphene wetting states in holey graphene….this is Yanbin’s 8th paper, Shayandev’s 24rd paper, and Parth’s 6th paper…congrats all.

In this paper, we study the streaming current and energy conversion in nanochannels grafted with poly-zwitterionic brushes…this is Guang’s 20th paper, Jahin’s 2nd paper, and Harnoor’s 8th paper from the group. Congratulations to all!!!

In this paper, we discover the real energetics of ions adsorption at the air-water interfaces by accounting for the effect of interactions between ions and capillary waves…this is Yanbin’s 7th paper, Shayandev’s 23rd paper, Parth’s 5th paper, and Hoyuan’s 10th paper from the group…..congrats all….

In this paper, we propose a new fabrication method for 3D printing inductors with commercially-relevant inductances. This is Yuan’s 4th paper from the group….many congratulations !!!!!

In this paper, we develop a theory to show how functionalizing nanochannels with end-charged polyelectrolyte brushes can enhance the thermoosmotic water transport in nanochannels…this is Raja’s 2nd paper, Haoyuan’s 9th paper, and Harnoor’s 7th paper from the group….congratulations to all!!!!!

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 !!!!
