By forcing paraxylene into single wall carbon nanotubes, a large amount of external work can be converted to excess solid-liquid interfacial energy. Due to the hysteresis of sorption isotherm curves, as the external pressure is decreased, only a small fraction of the interfacial energy can be released, making this system attractive for design of advanced energy absorption devices. As the infilt...

Transport of a sorbing solute in a two-dimensional steady and uniform flow field is modeled using a particle tracking random walk method. The solute is initially introduced from an instantaneous point source. Cases of linear and nonlinear sorption isotherms are considered. Local pore velocity and mechanical dispersion are used to describe the solute transport mechanisms at the local scale. The ...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

A biosorbent prepared from Ascophyllum nodosum seaweed biomass, FCAN2, was examined for its sorption capacity. Equilibrium batch sorption studies were performed using two-matal systems containing either (Cu + Zn), (Cu + Cd), or (Zn + Cd). In the evaluation of the two-metal sorption system performance, simple isotherm curves had to be replaced by three-dimensional sorption isotherm surfaces. In ...

The functional shape of a sorption isotherm is determined by underlying molecular interactions. However, doubts have been raised on whether the mechanism can be understood in principle from analyzing curves via range competing models. We shown recently that it possible to translate interactions rigorous statistical thermodynamics. aim this paper fill gap between thermodynamic theory and experim...

Corn distillers dried grains with solubles (DDGS) has high feed value due to its nutritive contents. The ratio of wet distillers grains (WDG) and condensed distillers solubles (CDS) added during the production ...

This paper defines the maximum possible vertical extent of hydrothermal circulation in granitic crust, and thus the maximum depth within which geothermal reservoirs can be encountered. To evaluate prospective geothermal fields we constructed a geothermal database in northern Honshu, Japan that includes 571 points of thermal data of existing wells and hot springs. Depth-temperature curves were n...

the modeling of kinetic and isotherm curves acquired in adsorption of polycyclic aromatic hydrocarbons (pahs) as a model compound (phenanthrene) on activated carbons in the organic solvent. all the runs were carried out in a batch system at atmospheric pressure, process temperature of 24±2°c, and using the 100 ml phenanthrene in cyclohexan. this experimental work was mainly focused on the study...

A method for estimating thermal desorption curves and desorption efficiencies of organic solvents from activated carbon was developed for the determination of adsorbed solvent by thermal desorption method, and the estimated values were compared with the experimental values. The Freundlich or the Langmuir isotherm was assumed in obtaining the solution. Thermal desorption experiments were conduct...
