Dipole alignment of water molecules flowing through a carbon nanotube
Hemant Kumar, Saheb Bera, Subhadeep Dasgupta +3
The fast flow rate of water through nanochannels has promising applications in desalination, energy conversion, and nanomedicine. We have used molecular dynamics simulations to sho…
Tunable strain soliton networks confine electrons in Van der Waals materials
Drew Edelberg, Hemant Kumar, Vivek Shenoy +2
Sliding and twisting van der Waals layers with respect to each other gives rise to moiré structures with emergent electronic properties. Electrons in these moiré structures feel we…
Effect of Cobalt Content on the Electrochemical Properties and Structural Stability of NCA Type Cathode Materials
Kamalika Ghatak, Swastik Basu, Tridip Das +2
At present, the most common type of cathode materials, NCA [Li_(1-x)Ni_(0.80)Co_(0.15)Al_(0.05)O_(2), x = 0 to 1], have a very high concentration of cobalt. Since cobalt is toxic a…
Effect of Decreasing Cobalt Content on the Electrochemical Properties and Structural Stability of Li_(1-x)Ni_(y)Co_(z)Al_(0.05)O_(2) Type Cathode Materials
Kamalika Ghatak, Hemant Kumar, Siva Nadimpalli +1
In Lithium ion batteries (LIBs), proper design of cathode materials influences its intercalation behavior, overall cost, structural stability, and its impact on environment. At pre…
Driving force of water entry into hydrophobic channels of carbon nanotubes: entropy or energy?
Hemant Kumar, Chandan Dasgupta, Prabal K. Maiti
Spontaneous entry of water molecules inside single-wall carbon nanotubes (SWCNTs) has been confirmed by both simulations and experiments. Using molecular dynamics simulations, we h…
Thermodynamics of Water Entry in Hydrophobic Channels of Carbon Nanotubes
Hemant Kumar, Biswaroop Mukherjee, Shiang-Tai Lin Chandan Dasgupta +2
Experiments and computer simulations demonstrate that water spontaneously fills the hydrophobic cavity of a carbon nanotube. To gain a quantitative thermody- namic understanding of…
