Size dependence of mechanical properties of gold at the micron scale in the absence of strain gradients
Classical laws of mechanics hold that mechanical properties are independent of sample size; however, results of experiments and molecular dynamics simulations indicate that crystals exhibit strongExpand

Plasticity in small-sized metallic systems: Intrinsic versus extrinsic size effect
A material strength depends on its microstructure, which in turn, is controlled by an engineering process. Strengthening mechanisms like work hardening, precipitate, and grain boundary strengtheningExpand

Nanoscale gold pillars strengthened through dislocation starvation
It has been known for more than half a century that crystals can be made stronger by introducing defects into them, i.e., by strain-hardening. As the number of defects increases, their movement andExpand

Ultralight Metallic Microlattices
A route is developed for fabricating extremely low-density, hollow-strut metallic lattices. Ultralight (<10 milligrams per cubic centimeter) cellular materials are desirable for thermal insulation;Expand

Tensile and compressive behavior of tungsten, molybdenum, tantalum and niobium at the nanoscale
In situ nanomechanical tests are carried out to investigate the tensile and compressive behavior of -oriented body-centered cubic (bcc) metals W, Mo, Ta and Nb with nanometer dimensions. We find thatExpand

In situ Mechanical Testing Reveals Periodic Buckle Nucleation and Propagation in Carbon Nanotube Bundles
Uniaxial compression studies are performed on 50-µm-diameter bundles of nominally vertical, intertwined carbon nanotubes grown via chemical vapor deposition from a photolithographically definedExpand

Size dependence of mechanical properties of gold at the sub-micron scale
The results of both experimental studies and molecular dynamics simulations indicate that crystals exhibit strong size effects at the sub-micron scale. In experimental studies, the size effects areExpand

Deformation mechanisms in nanotwinned metal nanopillars.
Nanotwinned metals are attractive in many applications because they simultaneously demonstrate high strength and high ductility, characteristics that are usually thought to be mutually exclusive.Expand

Transition from a strong-yet-brittle to a stronger-and-ductile state by size reduction of metallic glasses.
Amorphous metallic alloys, or metallic glasses, are lucrative engineering materials owing to their superior mechanical properties such as high strength and large elastic strain. However, their mainExpand

Thermal cure effects on electrical performance of nanoparticle silver inks
Physical, electrical, and morphological properties of thermally annealed silver nanoparticle thin films are described. These solution-deposited nanoparticle thin films form highly conducting films atExpand
