This paper explores the possibility of localizing water-free anion at negative electrode using Boron Nitride Nanotube in presence large concentration of Water-in-Salt Systems. This is Bhargav’s 2nd paper, Yanbin’s 17th paper, and Vishal’s 10th paper from the group. Congrats All !!!!

In this paper, we employ coarse-grained Molecular Dynamics Simulations to study the effect of base-pair mismatches on DNA plectoneme pinning. This work is a result of collaboration with Dr. Keir Neumann at NIH. Parth is the first author of the paper. This is Parth’s 12th paper from the group. Many congratulations !!!!

Vishal Sankar Sivasankar siccessfully defends his M.S. thesis on the topic “Electrokinetic transport in nanochannels grafted with backbone charged Polyelectrolyte brushes”. Vishal is the 5th M.S. student graduating from the group. His M.S. thesis work resulted in two high quality publications (one in Physical Review E and one in Physics of Fluids)….that apart, he has

In this paper, we study the effect of charge Density on the properties of polyelectrolyte chains, brush-supported counterions, and water molecules by employing all-atom MD simulations. This is Harnoor’s 20th paper, Turash’s 3rd paper, and Bhargav’s 1st paper from the group. Congrats All!!!!

The paper employs molecular dynamics simulations for studying friction in graphene channels of height less than 1 nanometer as a function of graphene misalignment. The work is a collaborative work with University of Waterloo, and Dr. Enrique Wagemann (my former postdoc advisee and currently a faculty member in University of Concepcion, Chile) is the lead

SMIEL Ph.D. student Harnoor Singh Sachar wins the STLE (Society of Tribology and Lubrication Engineering) Philadelphia section Scholarship.  Previously, two more Ph.D. students from SMIEL, Shayandev Sinha and Parth Desai had also won this Fellowship. 

Prof. Siddhartha Das delivered an invited talk on “Structure, Energetics, and Protein Sensing of Curved Lipid Bilayer Systems” in Biomaterials for Tissue Engineering (a Virtual Conference).

In this paper, we report the theoretical model on the massive increase in electroosmotic transport in nanochannels grafted with Polyelectrolyte Brushes modled using augmented Strong Stretching Theory (SST). This is Vishal’s 9th paper, Ankit’s 6th paper, and Harnoor’s 19th paper from the group. Congrats All !!!!!

In this paper, we develop a new theory to study the behavior, configuration, and electrostatics of polyelectrolyte (PE) brushes in large salt concentration. The findings match nicely with those predicted by our recent all-atom MD simulations of densely grafted PE brushes. This is Ankit’s 5th paper, Vishal’s 8th paper, and Harnoor’s 18th paper from the
