Probing the impact of grain interior and grain boundaries on the mechanical behavior of a high-Mn austenitic steel

Journal of Materials Research and Technology, 2022
We elucidate here the grain orientation/grain boundary dependence on the deformation behavior of high-Mn steel via tensile tests. The ultra-fine grained/fine grained (UFG/FG) specimen was characterized by superior strength-ductility combination as ...

Pressure dependence of diffusion in simple glasses and supercooled liquids [PDF]

, 2001
Using molecular dynamics simulation, we have calculated the pressure dependence of the diffusion constant in a binary Lennard-Jones Glass. We observe four temperature regimes.

A New Approach for Controlling Mesoporosity in Activated Carbon by the Consecutive Process of Air Oxidation, Thermal Destruction of Surface Functional Groups, and Carbon Activation (the OTA Method)

Molecules, 2021
A new and simple method, based entirely on a physical approach, was proposed to produce activated carbon from longan fruit seed with controlled mesoporosity.

Modelling selective activation of small myelinated nerve fibres using a monopolar point electrode [PDF]

, 1995
The aim of this study is to investigate theoretically the possibility for activation of small myelinated nerve fibres without activating larger ones when stimulating a nerve fibre bundle using a monopolar point electrode.

Pressure Dependence of Magnesite Creep

Geosciences, 2019
We determined the activation volumes (V*) for polycrystalline magnesite with grain sizes of 2 and 80 µm deforming by low temperature plasticity (LTP) mechanisms (kinking and dislocation glide), diffusion creep, and dislocation creep at temperatures ...

Cerebral Blood Volume Changes during Brain Activation [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2012
Cerebral blood volume (CBV) changes significantly with brain activation, whether measured using positron emission tomography, functional magnetic resonance imaging (fMRI), or optical microscopy. If cerebral vessels are considered to be impermeable, the contents of the skull incompressible, and the skull itself inextensible, task- and hypercapnia ...

Atomistic Characterization of Stochastic Cavitation of a Binary Metallic Liquid under Negative Pressure [PDF]

, 2011
We demonstrate the stochastic nature of cavitation in a binary metallic liquid Cu_(46)Zr_(54) during hydrostatic expansion by employing molecular dynamics (MD) simulations using a quantum mechanics (QM)-derived potential.

Activation Volume Measurements

Zeitschrift für Naturforschung A, 1971
Abstract The determination of the activation volume of diffusion is one of the best methods for the in­vestigation of the relaxation of atoms or ions around defects. This paper discusses two experimental techniques for the determination of the activation volume for diffusion, by studying the effect of hydrostatic pressure on tracer ...
