in present study, molecular dynamics simulation of cadmium (ii), lead (ii) and copper (ii) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. the results showed that, most of the particles had the highest affinity of ion exchanging with lead (ii) and the lowest affinity with copper (ii). the calculated mean ion-exchange ratios showed t...

The mathematical modeling and numerical simulation of semiconductor-electrolyte systems play important roles in the design of high-performance semiconductor-liquid junction solar cells. We propose in this work a macroscopic mathematical model, a system of nonlinear partial differential equations, for the complete description of charges transfer dynamics in such systems. The model consists of a ...

In this paper we consider buoyancy-driven flow and directional solidification of a ternary alloy in two dimensions. A steady flow can be established by forcing liquid downward at an average rate V through a temperature gradient that is fixed in the laboratory frame of reference and spans both the eutectic and liquidus temperature of the material being solidified. Our results include both a line...

Physicochemical studies of the human serum albuminCu(II)-L-histidine (HSA-Cu(II)-L-His) ternary complex at pH 7.5 indicate several interesting features. 1. The dissociation constants of the HSA-Cu(II)-L-His ternary complex and the HSA-Cu(I1) binary complex are 1.38 X 1O-22 and 6.61 x lOen, respectively. 2. The absorption spectrum of the ternary complex system has characteristics similar to thos...

The use of multi-valued logic in VLSI circuits can reduce the chip area significantly. Moreover, there are several additional advantages of using multi-valued logic in VLSI over the conventional Binary logic, such as energy efficiency, cost-effectiveness and so on. It has been shown that Base-3 number system is nearly optimal for computation. This paper is composed of two parts. In the first pa...

This paper presents a new approach to an on-chip asynchronous transmission system suitable for next generation asynchronous on-chip networks. It implements multivalued logic to reduce the number of wires and a low-voltage swing for lower dynamic power dissipation. Furthermore, the transmission system described here enjoys fully static design and has zero static power consumption. Two versions o...

Liquid-liquid equilibria for the (water + lactic acid + benzyl alcohol or p-xylene) ternary systems were investigated at atmospheric pressure and in the temperature range from 298.15-318.15 K. The studied systems exhibit two types of liquid-liquid equilibrium (LLE) behavior. The system consisting of benzyl alcohol displays type-1 LLE behavior, while a type-2 behavior is exhibited by th...
