Advanced Engineering Materials, EarlyView.In this manuscript, the processability of X2CrNiMo17‐12‐2 powder coated with silicon carbide, silicon, and silicon nitride nanoparticles is investigated. The amount of nanoparticles varies from 0.25 to 1 vol%. By coating the powder feedstock material with nanoparticles, an enlargement of the process window and an increase in the build rate are achieved.

Elasticity $\mathscr{M}$-tensors and the Strong Ellipticity Condition [PDF]
arXiv, 2017 In this paper, we establish two sufficient conditions for the strong ellipticity of any fourth-order elasticity tensor and investigate a class of tensors satisfying the strong ellipticity condition, the elasticity $\mathscr{M}$-tensor. The first sufficient condition is that the strong ellipticity holds if the unfolding matrix of this fourth-order ...

Microscale Interrogation of 3D Tissue Mechanics
Frontiers in Bioengineering and Biotechnology, 2019 Cells in vivo live in a complex microenvironment composed of the extracellular matrix (ECM) and other cells. Growing evidence suggests that the mechanical interaction between the cells and their microenvironment is of critical importance to their ...

Wealth Heterogeneity and the Income Elasticity of Migration
, 2017 How do income shocks affect international migration flows from poor countries? Income growth not only increases the opportunity cost of migration but also eases liquidity constraints. I develop a method to separate these countervailing individual effects

Advanced Engineering Materials, EarlyView.The fabrication and post‐treatment via solvent annealing of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate‐based electrodes using spray deposition in a roll‐to‐roll setup are presented. The decrease in sheet resistance and its correlation with nanostructure and molecular structure in the electrodes as a function of the processing parameters is ...

Is the Armington Elasticity Really Constant across Importers? [PDF]
This paper shows that the Armington elasticity, which refers to both the elasticity of substitution across goods and the price elasticity of demand under the assumption of a large number of varieties, systematically changes from one importer country to ...

Nomenclature in Elasticity [PDF]
Nature, 1885 THE word stress is used, sometimes in the sense of load, sometimes in that of load per unit area. Clearness, however, requires these two ideas to be kept perfectly distinct, and therefore to be denoted by separate terms. Load is surely expressive enough, or, if not, there is the more comprehensive word force: why then use stress synonymously?

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing
Advanced Engineering Materials, EarlyView.By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...

Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, and substantially larger in disaggregated studies. This may be an artifact of heterogeneity.
