C. High pressureD. Equations-of-stateThe equation V(P)=Vo−B ln[(1+C(P−1)], where V is volume at any pressure (P), Vo the volume at 1 bar and B and C fitted parameters, is shown to be useful as an equation of state for many solids over a large pressure range. The...
say 25 °C. If we slowly push in the plunger while keeping temperature constant, the gas in the syringe is compressed into a smaller volume and its pressure increases; if we pull out the plunger, the volume increases and the pressure decreases. This example...
2), the “belt” is perhaps the most important apparatus used for large-volume, high-pressure work (see Fig. 3). This stems from its development, which provided the increased pressure and temperature conditions necessary for the original synthesis of diamonds. Although few research laboratories ...
Full size image Our results demonstrated that the 2D (CH3–(CH2)9)2NH2Cl undergoes interlayer expansion as large as 13% along the length direction of carbon chains (caxis) whileabplane remains nearly unchanged, consequently volume expansion as much as 12% occurs during phase transition. Such a...

Scientific Reports volume 12, Article number: 3691 (2022) Cite this article 2285 Accesses Metrics details Abstract The first-principles calculations based on density functional theory with projector-augmented wave are used to study the anisotropy of elastic modulus, mechanical hardness, minimum thermal ...
The block assumes the volume and mass of fluid inside the valve is very small and ignores these values. As a result, no amount of fluid can accumulate in the valve. By the principle of conservation of mass, the mass flow rate into the valve through one port equals that out of the valv...
Using the third-order Birch-Murnaghan equation of state (EoS), we fitted the pressure-volume-temperature (P-V-T) data and obtained the zero-pressure bulk modulus K0=138(2) GPa, its pressure derivative K0'=3.0(3), the temperature derivative of the bulk modulus ((∂K/∂T)P=-0.004(...
As a final result, we obtain the chemical potential gradients for all components of the mixtures that can be easily translated in term of compositions through Equation of State modelling. The most important features of the final expressions are: i) the species relative separation in a thermal ...
The equations that describe the dependence of reaction rates on pressure or volume are analogous to the Arrhenius equation, which links reaction rates to temperature. Furthermore, pressure effects are governed by Le Chatelier's principle, which states that a system at equilibrium subjected to a ...
