The growing attention regarding a more sustainable future, and thus into energy recovery waste reduction technologies, has intensified the interest towards processes which allow to exploit biomasses generate energy, such as anaerobic digestion. Improving efficiency of this industrial application is crucial increase methane production, essential from economic, environmental safety point view. Th...

The use of samarium-doped ceria (SDC) electrolytes in SOFCs (solid oxide fuel cells) lowers the open circuit voltage (OCV) below the Nernst voltage (Vth), which is obtained using yttria-stabilized zirconia (YSZ) electrolytes. The OCV is classically calculated with Wagner’s equation. However, using SDC electrolytes requires both qualitative and quantitative experimental verification of leakage c...

a mixing rule for the mixtures of hard-spheres is presented which can be reduced to the standard van der waals mixing rule at low densities. the effectiveness of the mixing rule for the size and energy parameters of lennard-jones fluid are examined by combining them with an equation of state to calculate thermodynamic properties. the results of calculation are compared with the molecular dynami...

A high-temperature equation of state (EoS) for the fcc phase solid lead and liquid was developed herein using experimental data on thermodynamic properties, volumetric thermal expansion, compressibility, temperature-dependent bulk modulus, sound velocity from ultrasonic measurements melting curve. The whole totality optimized Murnaghan EoS over a pressure range 0–130 kbar. temperature dependenc...

High-temperature equations of state for solid and liquid aluminum were constructed herein using experimental data on thermodynamic properties, thermal expansion, compressibility, bulk modulus sound velocity measurements, supplemented with phase diagram (melting curve). The entire set was optimized the temperature-dependent Tait equation over a pressure range up to 800 kbar temperature from 20 K...
