An attempt was made to study the kinetics of this reaction by measuring the concentration of silver nanoparticles instead of the silver ions as a function of time. The initial concentration of the reducing agent (trisodium citrate) was taken to be nearly 20 times that of the initial ...
Empirical models, such as Freundlich and Langmuir equations, are extensively used to describe sorption reaction of reaction solutes. The Freundlich equation is one of the simplest nonlinear sorption model (Freundlich, 1909), which can be expressed as (2)S=KfCN where S represents the (total) amou...
The H–W method has also been implemented for measuring the partial conductivities of triple ionic-electronic conducting oxides [51,95,96]. Until now, the H–W method is mainly used for determining the electronic conductivity of triple ionic-electronic conducting oxides. For determining electronic ...

1.4 The Dupré equations What one might call the original Dupré equation for the free energy of interaction between condensed-phase materials, 1 and 2 (ΔG12), in vacuo or in air, reads as follows: (2.8)ΔG12=γ12−γ1−γ2. Most authors cite Anastase Dupré (1869) as the or...
It is basically the classical mass-balance law of continuum mechanics, which expresses that the net mass-flux across the boundaries of a control volume must be equal to the accumulated mass. The first term of Eq. (A.15) accounts for the rate of change of mass at the point, the second ...
Brand identity communicates to consumers what a brand provides or stands for, focuses on meeting consumers’ symbolic needs more than their functional needs, and communicates uniqueness and the status and prestige offered by the brand compared to competitors through brand distinctiveness and brand prestig...
