In Situ Study of Resistive Switching in a Nitride‐Based Memristive Device

open access: yesAdvanced Functional Materials, EarlyView.
In situ TEM biasing experiment demonstrates the volatile I‐V characteristic of MIM lamella device. In situ STEM‐EELS Ti L2/L3 ratio maps provide direct evidence of the oxygen vacancies migrations under positive/negative electrical bias, which is critical for revealing the RS mechanism for the MIM lamella device.

CONTACT PROBLEM ON TORSION OF TRANSVERSELY ISOTROPIC ELASTIC HALF-SPACE WITH INHOMOGENEOUS TRANSVERSELY ISOTROPIC COATING BY ROUND DIE

open access: yesВестник Донского государственного технического университета, 2018
An axisymmetric contact problem of the elasticity theory on the torsion of the transversely isotropic half-space with the inhomogeneous coating by the round die is considered.

Nonlinear elasticity of monolayer graphene

open access: yes, 2009
By combining continuum elasticity theory and tight-binding atomistic simulations, we work out the constitutive nonlinear stress-strain relation for graphene stretching elasticity and we calculate all the corresponding nonlinear elastic moduli.

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

Existence and Convergence of Solutions of the Boundary Value Problem in Atomistic and Continuum Nonlinear Elasticity Theory

open access: yes, 2016
We show existence of solutions for the equations of static atomistic nonlinear elasticity theory on a bounded domain with prescribed boundary values. We also show their convergence to the solutions of continuum nonlinear elasticity theory, with energy ...

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites

open access: yesAdvanced Functional Materials, EarlyView.
Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

THE PROBLEMS SOLUTION OF ELASTICITY THEORY WITH SEPARATE DETERMINATION OF THE PURE STRAIN AND VOLUMETRIC DEFORMATION

open access: yesNauka ta progres transportu, 2009
In the article it is proposed to divide the overall deformation of elastic medium on two independent components – pure and voluminous ones, which are subjected to different physical relationships and determined separately.

Calculating the scale elasticity in DEA models. [PDF]

open access: yes
In economics scale properties of a production function is charcterised by the value of the scale elasticity. In the field of efficiency studies this is also a valid approach for the frontier production function. It has no good meaning to talk about scale

Elasticity Theory and Shape Transitions of Viral Shells

open access: yes, 2005
Recently, continuum elasticity theory has been applied to explain the shape transition of icosahedral viral capsids - single-protein-thick crystalline shells - from spherical to buckled/faceted as their radius increases through a critical value ...
