Electrorheological (ER) effects of alginic acid and alginate salts (Na(+) alginate, NH(4)(+) alginate, and Ca(2+) alginate) dispersed suspensions were investigated under DC electric fields. A noteworthy result is that the Ca(2+) alginate dispersed su

CdS quantum dots (QDs) were uniformly deposited on mesoporous TiO 2 films by high-pressure coating with liquid carbon dioxide (l-CO 2 ) as a coating solvent. The size and coverage of CdS QDs over the TiO 2 surface were controlled by the number of l-C

A semi-empirical molecular clustering based lattice fluid model is presented to improve the classical lattice model for volumetric properties in the critical region. This model is based on the two assumptions: (1) the Helmholtz energy is individually

Molecular dynamic simulations have been evaluated for systems containing supercritical carbon dioxide to predict high-pressure diffusion coefficients of binary mixtures. Diffusion coefficients of high boiling compounds in supercritical fluids are imp

Continuous transesterification of palm olein oil using supercritical methanol was investigated in the absence of a catalyst. The variables studied were reaction temperature (270–350 °C), pressure (20–40 MPa), and residence time (5–25 min), wit

The synthesis of ionic polymer, its solvent-induced switching behavior, the fabrication of membranes with the thermal-induced phase separation method (TIPS), and Li+ adsorption isotherm on the membranes are described. The polymer membranes prepared w

We present an analytic equation of state (EOS) that describes the three phases of real substances and their transition in a single isotherm. To develop the repulsive contribution of the EOS for the...

In this work, the solubility curves for the CO 2 + neopentyl glycol diacrylate (NPGDA) and CO 2 + neopentyl glycol dimethacrylate (NPGDMA) systems are measured in static method at five temperatures of (313.2, 333.2, 353.2, 373.2 and 393.2) K and pres

Among the thermodynamic models applicable to solid–liquid–vapor phases, Yokozeki’s model is considered as the first repulsion-based analytic equation of state (EOS) in which a discontinuity is introduced in the isotherm. However, it was found t

In spite of its simplicity and a well-defined theoretical basis, the Flory–Guggenheim approach is conventionally regarded as inapplicable to off-lattice system since the insertion probability of the approach does not account for the excluded region
