Strength of polycrystalline coarse-grained platinum to 330 GPa and of nanocrystalline platinum to 70 GPa from high-pressure x-ray diffraction data
(AMER INST PHYSICS, 2008-03-15)
X-ray diffraction patterns from platinum foil 300 nm grain size have been recorded up to
330 GPa using a beveled-anvil diamond cell. The compressive strength has been determined from
the analysis of the diffraction ...
Modelling grain boundary migration during geometric dynamic recrystallization
(TAYLOR & FRANCIS LTD, 2008)
High-angle grain boundary migration is predicted during geometric dynamic recrystallization (GDRX) by two types of mathematical models. Both models consider the driving pressure due to curvature and a sinusoidal driving ...
Soybean compressibility and bulk density
(Amer Soc Agricultural Engineers, 2000-11-01)
The objective of this project was to study the influence of surcharge pressure and moisture content on the compressive behavior and bulk density of soybeans. Three varieties were selected with varying dimensions and shapes. ...

Vapor pressure of aqueous solutions of electrolytes reproduced with coarse-grained models without electrostatics
(American Chemical Society, 2016-05)
The vapor pressure of water is a key property in a large class of applications from the design of membranes for fuel cells and separations to the prediction of the mixing state of atmospheric aerosols. Molecular simulations ...
Contact forces distribution for a granular material from a Monte Carlo study on a single grain
(Granular Matter, 2018-02)
The force network ensemble is one of the most promising statistical descriptions of granular media, with an entropy accounting for all force configurations at mechanical equilibrium consistent with some external stress. ...
Fracture toughness evaluation of WC–10 wt% Co hardmetal sintered under high pressure and high temperature

Creation of heterogeneous microstructures in copper using high-pressure torsion to enhance mechanical properties
(Elsevier Science SA, 2019-05)
This paper studies the effects of high-pressure torsion (HPT) at ambient temperature on microstructural evolution and mechanical properties enhancement in pure copper. The aim is to introduce gradient microstructure, with ...
Grain boundary and grain interior conduction in γ′-Bi2MoO6
(Elsevier Science, 2005-07)
Impedance spectroscopy of fine grained (<10 μm) γ′- Bi2MoO6 samples, in the frequency range of 0.1 Hz-250 kHz, relevant to sensor applications, up to 800°C, has been used to characterize grain boundary and grain interior ...
Role of oxygen on the phase stability and microstructure evolution of CaCu3Ti4O12 ceramics
(2017-01-01)
Phase stability and microstructure evolution of polycrystalline CaCu3Ti4O12 (CCTO) ceramics were studied by controlling the partial pressure of oxygen (from a poor to an oxygen rich atmosphere) during the sintering process ...
