Although significant effort has been made on using graphene as a reinforcement in metal
matrix nanocomposites due to its extraordinary high strength and high modulus, metal …

Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

Understanding the fundamental of contact-induced behavior in metals is critical for the
studies of associated mechanical properties. Although nanocontact plasticity in the …

Most metallic elements have a crystal structure that is either body-centered cubic (bcc), face-
centered close packed, or hexagonal close packed. If the bcc lattice is the …

Amorphous solids lack long-range order. Therefore identifying structural defects—akin to
dislocations in crystalline solids—that carry plastic flow in these systems remains a daunting …

The biconcave shape and corresponding deformability of the human red blood cell (RBC) is
an essential feature of its biological function. This feature of RBCs can be critically affected …

Nanocrystalline metals and alloys, with average and range of grain sizes typically smaller
than 100 nm, have been the subject of considerable research in recent years. Such interest …

Nanoindentation has become a commonplace tool for the measurement of mechanical
properties at small scales, but may have even greater importance as a technique for …

Different approaches to the preparation of superhard coatings such as intrinsically
superhard materials, coatings whose hardness is enhanced by energetic ion bombardment …

We present a three-dimensional computational study of whole-cell equilibrium shape and
deformation of human red blood cell (RBC) using spectrin-level energetics. Random …
