The existence of surface nanobubbles has already been confirmed by variable detection methods, but the mechanism their extraordinary stability remains unclear and aroused widespread research interest in past 2 decades. Experiments theoretical analyses have tried to account for these stabilities such as very long lifetime, high pressure small contact angle. Attractive hydrophobic potential was a...
Nanobubbles have attracted wide scientific attention due to their large number of potential applications in nanotechnology, and they are ubiquitous during natural gas hydrates (NGHs) mining which is one the strategic energy resources. Molecular dynamic simulations were performed investigate CH4 nanobubble characteristics NGHs dissociation. The nucleation mechanism evolution nanobubbles vary wit...
We investigate the impact of strained nanobubbles on the conductance characteristics of graphene nanoribbons using a combined molecular dynamics - tight-binding simulation scheme. We describe in detail how the conductance, density of states, and current density of zigzag or armchair graphene nanoribbons are modified by the presence of a nanobubble. In particular, we establish that low-energy el...
Recent theoretical proposals suggest that strain can be used to engineer graphene electronic states through the creation of a pseudo-magnetic field. This effect is unique to graphene because of its massless Dirac fermion-like band structure and particular lattice symmetry (C3v). Here, we present experimental spectroscopic measurements by scanning tunneling microscopy of highly strained nanobubb...
