It is challenging to compute the partition function (Q) for systems with enormous configurational spaces, such as fluids. Recently, we developed a Monte Carlo technique (an energy partitioning method) for computing Q [ J. Chem. Phys. 2011 , 135 , 174105 ]. In this paper, we use this approach to compute the partition function of a binary fluid mixture (carbon dioxide + methane); this...

Diacylphosphatidylinositol (PI) is the starting reactant in the process of phosphatidylinositide-related signal transduction mediated through the lipid raft domain. We investigated intermolecular interactions of PI with major raft components, sphingomyelin (SM) and cholesterol (Chol), using surface pressure-molecular area (π-A) isotherm measurements. The classical mean molecular area versus com...

<p>This study aims to determine: the ability of corn cobs and eggshells as Zn metal adsorbents, functional groups adsorbent, what isotherm patterns occur in adsorbent adsorbing metal, optimum ratio mass composition adsorption, contact time for eggshell concentration adsorbate be adsorbed by adsorbents. This used an experimental method laboratory. characterization includes using FTIR, test...

The infiltration of pressurized aqueous solutions of sodium cholate hydrate (CSH) and ammonium 8-anilino-1-naphthalenesulfonate (1,8-ANS-NH4) in a hydrophobic silica gel is investigated experimentally. The CSH and 1,8-ANS-NH4 molecules act as promoters that lower the infiltration pressure in relatively large nanopores, resulting in the staged sorption isotherm curves. When the CSH concentration...

Behaviors of liquids in two-dimensional (2D), lyophobic nanoenvironment were investigated experimentally by using a surface-modified, graphene-based nanoslit composite (GBNC). Different from previous reports on one-dimensional (1D) nanofludic behaviors, the infiltration pressure of 2D nanofluid is not dependent on the infiltration volume, leading to a flat infiltration plateau in the sorption i...

The inverse method is a numerical method for fast estimation of adsorption isotherm parameters directly from a few overloaded elution profiles and it was recently extended to adsorption isotherm acquisition in gradient elution conditions. However, the inverse method in gradient elution is cumbersome due to the complex adsorption isotherm models found in gradient elution. In this case, physicoch...

background: obesity and diabetes are the most important problems of public health. evidence from molecular animal research and epidemiologic investigations indicate that calcium intake may have an influence on body composition, weight and insulin resistance. the objective of this study was to determine the effects of calcium supplementation on body composition, weight, insulin resistance and bl...

Although insulin sensitivity is correlated with high blood pressure in adults, it is unclear whether such a relationship exists in children across ethnic groups. Therefore, the aims of the study were to establish (1) if body composition and insulin sensitivity were related to blood pressure in children, and (2) if any differences in blood pressure between white and black children were explained...

High entropy alloys belong to a new and promising class of functional materials for solid-state hydrogen storage. In this context, novel single-phase body centered cubic (bcc) high alloy Ti0.30V0.25Zr0.10Nb0.25Mo0.10 was prepared. The physicochemical sorption properties have been determined by both laboratory large-scale facilities. This can quickly absorb up 2.0 H/M (2.8 wt.%) at room temperat...

Water pollution caused by the lead(II) from the spent liquor has caught much attention. The research from the theoretical model to application fundaments is of vital importance. In this study, lead(II) adsorption isotherms are investigated using a series of hybrid membranes containing mercapto groups (-SH groups) as the hybrid adsorbents. To determine the best fitting equation, the experimental...
