Metals, 2018 A solution-hardening of AISI 316L stainless-steel powder was conducted. The expansion of the crystal lattice and a strong increase in the nanoindentation hardness confirm the successful diffusion of carbon and nitrogen in the interstices.

Influence of cross-section geometry and wire orientation on the phonon shifts in ultra-scaled Si nanowires [PDF]
, 2011 Engineering of the cross-section shape and size of ultra-scaled Si nanowires (SiNWs) provides an attractive way for tuning their structural properties. The acoustic and optical phonon shifts of the free-standing circular, hexagonal, square and triangular

Channel Hardening and Favorable Propagation in Cell-Free Massive MIMO With Stochastic Geometry [PDF]
IEEE Transactions on Communications, 2017 Cell-free (CF) massive multiple-input multiple-output (MIMO) is an alternative topology for future wireless networks, where a large number of single-antenna access points (APs) are distributed over the coverage area.

Dynamics of Dislocations in Smectic A Liquid Crystals Doped with Nanoparticles
Crystals, 2019 Edge dislocations are linear defects that locally break the positional order of the layers in smectic A liquid crystals. As in usual solids, these defects play a central role for explaining the plastic properties of the smectic A phase. This work focuses

Strain Hardening of Polymer Glasses: Entanglements, Energetics, and Plasticity [PDF]
, 2008 Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While stress-strain curves for a wide range of temperature can be fit to the functional form predicted by entropic network models, many other results are ...

Back stress strengthening and strain hardening in gradient structure
, 2016 We report significant back stress strengthening and strain hardening in gradient structured (GS) interstitial-free (IF) steel. Back stress is long-range stress caused by the pileup of geometrically necessary dislocations (GNDs).
