Specific Heat Capacity of Confined Water in Extremely Narrow Graphene Nanochannels

Specific heat capacity of extremely confined water determines its performance in the transfer as sizes devices decrease to nanoscales. Here, we report basic data specific narrow graphene nanochannels below 5 nm height using molecular dynamics simulations. The results show that is size-dependent, and commensurability effect presents confinement decreases 1.7 nm. deviation with bulk attributed variation configuration features, including density distribution hydrogen bonds, vibration velocity auto-correlation function vibrational states. This work unveils effects their physical mechanisms nanoconfined water, provided here have wide prospects for energy applications at
