Abstract:
By using the thermodynamic equations, the ESTPHAD (Estimation of Phase Diagrams) method developed by us has been made suitable for calculating the immiscibility gap of monotectic systems. 2 special parameters were introduced in the basic equation of ESTPHAD which ensure the description of the characteristics of monotectic curve on the basis of the boundary conditions created by us. By means of the monotectic ESTPHAD equation, the equations of separation temperatures of monotectic parts in the Zn-Bi and Al-Bi systems were calculated (with an accuracy of +/- 10K) on the basis of the reference da

Abstract:
Metastable liquid-liquid immiscibility region in the Al2O3–SiO2 system was calculated by a regular solution model using three sets of liquidus data from the stable phase diagrams reported. These calculations indicated that the immiscibility region was richer in Al2O3 composition than those reported before. A miscibility gap calculated using the liquidus data reported by Klug et al. [F.

Abstract:
Abstract The miscibility gap of the Ga–Pb system has been investigated by different experimental methods and techniques. Viscosity, acoustic and electrical conductivity measurements were carried out through the entire immiscibility region. Possible reasons of revealed discrepancies in the absolute values of the phase separation temperatures are discussed in relation with peculiarities of the experimental methods employed. The shape of the miscibility gap has been analysed.

Abstract:
Liquid immiscibility plays an important role in the formation of carbonatites and associated alkaline Si-undersaturated magmas. Experiments in the sodium carbonate-aluminosilicate systems suggest that the carbonate-silicate miscibility gap is limited by crustal and shallow mantle pressures (up to 2.5 GPa). Unlike in the potassium-rich carbonate-aluminosilicate systems, the carbonate-silicate miscibility gap was established at pressures of 3.5–6 GPa. It is therefore interesting to elucidate the immiscibility range under intermediate pressures, corresponding to 100–200 km depths. Here we conduct

Abstract:
The processing of microporous glassy carbon derived from furfuryl alcohol and ethylene glycol mixtures has been studied, with emphasis on understanding and controlling microstructure development. It is shown that this system exhibits a polymerization-dependent miscibility gap, and that the carbon microstructure is determined by phase separation in the liquid state. Variations in carbon microstructure with composition and thermal history can be understood in terms of the time-dependent immiscibility and resulting phase separation.

Abstract:
The metastable immiscibility region in the Al2O3–SiO2 system was calculated by conventional thermodynamic equations using thermodynamic parameters obtained from molecular dynamics simulation. The calculated miscibility gap has a consolute temperature of around 1500 °C at the critical composition of about 20 mol% Al2O3 and spreads more widely towards the Al2O3-rich composition side than the SiO2-rich side. The calculated miscibility gap in this study showed a fair agreement with that reported by Ban et al. [T. Ban, S. Hayashi, A. Yasumori, and K. Okada, J. Mater. Res. 11, 1421 (1996)] calculate

The Cu-Zr-Ag system is characterized by a miscibility gap. The liquid separates into Ag-rich and Cu-Zr rich liquids. Yttrium was added to the Cu-Zr-Ag and Cu-Zr-Ag-Al systems and its influence on liquid immiscibility was studied. This alloying element has been chosen to check the effect of the heat of mixing between silver and the given element. In the case of Ag-Y system it is highly negative (-29 kJ/mol). The liquid becomes immiscible in the Cu-Zr-Ag-Y system. To the effect of Y addition the quaternary liquid decomposed into Ag-Y rich and Cu-Zr rich liquids. The Y addition increased the fiel

A metastable miscibility gap has been shown to exist oyer much of the SiO2(s) -mullite(s) phase field by various indirect methods. The various proposed boundaries of this liquid-liquid immiscibility region, however, significantly disagree in their widths and critical point positions. The overall aim of our research is to directly determine the miscibility gap boundaries by using TEM/EDS on suitably equilibrated phases of rapidly solidified SiO2-Al2O3 glass. Rapid solidification by roller quenching (∼106°C/sec) and by ice- water quenching (~1035°C/sec) was used so that a wide range of compositi

Abstract The Nansatsu district of southern Kyushu has been the site of calc-alkaline volcanism for the last 10 m.y., shifting eastward with time. Associated hydrothermal activity followed deposition of the volcanic host rocks by about 0.5 m.y. and was characterized by interaction of magmatic fluids with meteoric water under epithermal conditions, resulting in the formation of high sulfidation Cu-Au deposits at Kasuga, Iwato, and Akeshi.

Abstract:
In-Vessel Retention (IVR), which arrests relocated molten core materials in the vessel during severe accident, has been singled out as an appealing accident management approach to many reactors. The heat transfer imposed by in-vessel corium is a vital part for IVR success considering the difficulty of significantly altering ex-vessel CHF. For a given decay power, corium pool configuration determines the heat flux profile along the vessel wall, which may produce uncertainties associated with IVR strategy.

Abstract Leaks through the production packer, which serves as a primary barrier can compromise well integrity. Traditional methods to restore packer integrity typically entail costly workover operations, necessitating the deployment of a rig to replace the upper completion. This paper presents a cost-effective solution utilizing thermosetting resin, offering an economically viable alternative for remediating packer leaks without the need for heavy workover rigs. The method employs gravity-feeding of thermosetting resin through the annular fluids to seal leaks located often thousands of meters

Abstract:
Abstract Injection pressure is a key parameter in the design of a Huff-and-Puff EOR process in organic-rich shales. Reservoir engineering studies have shown that injection pressure and miscibility play a role during Huff-and-Puff EOR. However, during field implementation, the injection pressure is often limited by the number of compressors and in several cases, the gas injected might not reach sufficient pressure to achieve a state of complete miscibility with the oil. These scenarios lead to a condition of partial miscibility or immiscibility which impacts the efficiency of the recovery mecha
