In this paper, we study the electrokinetic energy generation in nanochannels grafted with pH-responsive polyelectrolyte brushes modeled using our recently developed Strong Stretching Theory. This is the most advanced continuum modelling of electrokinetic transport in brush-grafted nanochannel till date. This is Harnoor’s 13th paper from the group and Vishal’s 3rd paper from the group. Congrats to both !!!!
