We consider an isotropic solid mixture of M A atoms of component A and M B of component B in volume \\(ilde V\\). This is modelled by a regular lattice of N sites, the volume 蠀0 per lattice site being as usual taken as constant and used as the standard volume in (1.54). ...
Liquids may be divided into two general categories:pure liquidsandliquid mixtures. On Earth,wateris the most abundant liquid, although much of the water with which organisms come into contact is not in pure form but is a mixture in which various substances are dissolved. Such mixtures include ...
An example at ambient pressure is shown in Figure 14.19a for mixtures of cyclohexane with methanol. A single liquid phase is present at point a. If the mixture is cooled along line aj, separation into two phases begins at point b. For example, when a temperature corresponding to point c ...
As a means to treat the waste gas, a solid phase adsorbent or their mixtures can be employed. Once the waste gas condenses at the surface of the adsorbent, adsorption of target components contained in the gas occurs either physically or chemically. Activated carbon is the most commonly used ...
The book includes examples of mixtures of two powders, the process of dissolution of a powder in a liquid, and the homogenization of a pasty product. The types of devices needed, the criterion for homogeneity, the expended mechanical power, the flow processed, and the time required for th...
Solid + liquid phase diagrams have been determined for 1-octanol, 1-nonanol, 1-decanol, or 1-undecanol + decylamine mixtures. Solid addition compounds form... U Domańska,M Marciniak - 《Industrial & Engineering Chemistry Research》 被引量: 30发表: 2004年 ...
Porous or solid multi-component mixtures are ubiquitous in nature and extensively used as industrial materials such as multifunctional energetic structural materials (MESMs), metallic and ceramic powder for shock consolidation, and porous armor materials. In order to analyze the dynamic behavior of a ...
Solid-phase extraction is a commonly employedsample preparation methodin complex matrices. Differences in affinity of various molecules to active sites located on the surface ofsorbentmaterials resulting in the separation of mixtures of different molecules are the basic principle ofSPE. SPE is used to...
The form II resonances appear upfield from the form I peaks, and the mixtures of the two forms can be easily observed at intermediate temperatures. Several models for the form II conformation have been proposed, including one in which the skew angle is decreased from +109° to ± 80° to ...
In this paper the theory of mixtures is used to develop a two-phase model of an avascular tumour, which comprises a solid, cellular, phase and a liquid phase. Mass and momentum balances which are used to derive the governing equations are supplemented by constitutive laws that distinguish the...
