Graphene quantum dots embedded in hexagonal boron nitride sheets
Junwen Li, Vivek B. Shenoy
We have carried out first-principles calculations on electronic properties of graphene quantum dots embedded in hexagonal boron nitride monolayer sheets. The calculations with dens…
Strain Stiffening Induced by Molecular Motors in Active Crosslinked Biopolymer Networks
Peng Chen, Vivek B. Shenoy
We have studied the elastic response of actin networks with both compliant and rigid crosslinks by modeling molecular motors as force dipoles. Our finite element simulations show t…
Anomalous Strength Characteristics of Tilt Grain Boundaries in Graphene
Rassin Grantab, Vivek B. Shenoy, Rodney S. Ruoff
Using molecular dynamics simulations and first principles calculations, we have studied the structure and mechanical strength of tilt grain boundaries in graphene sheets that arise…
Low-Reynolds number swimming in gels
Henry C. Fu, Vivek B. Shenoy, Thomas R. Powers
Many microorganisms swim through gels, materials with nonzero zero-frequency elastic shear modulus, such as mucus. Biological gels are typically heterogeneous, containing both a st…
