Potential space

A phase diagram displays the regions of the potential space where the various phases of the system are stable. The potential space is given by the variables of the... 

We have now derived the phase boundary between the two liquids. By analogy with our earlier examples, the two phases may exist as metastable states in a certain part of the p,T potential space. However, at some specific conditions the phases become mechanically unstable. These conditions correspond to the spinodal lines for the system. An analytical expression for the spinodals of the regular solution-type two-state model can be obtained by using the fact that the second derivative of the Gibbs energy with regards to xsi)B is zero at spinodal points. Hence,... 

Normally, the space between the visceral and parietal pleura is only a potential space. More accurately, it is a surface covered with a thin film of fluid, to lubricate movement of the lung. Both pleura are relatively flexible and passive, and do not limit the inflation or deflation of the lungs during the breathing cycle. 

Pleural cavity The potential space between the linings or coverings of the lung and thorax. 

The potential space required for such a solution is large, though this problem is disappearing. 

The scaffold functions to (a) provide structural integrity and to define a potential space for the engineered tissue (b) guide the restructuring that occurs through the proliferation of the donor cells and the in-growth of the host tissue (c) maintain distances between the parenchymal cells that permit diffusion of the gas and nutrients and, possibly, the in-growth of vasculature from the host bed and (d) transmit the tissue-specific mechanical forces to cue the behavior of the cells within it (Marler etal. 1998).

The sub-Tenon s space is located between the eyeball and the anterior surface of Tenons capsule, which separates the intra-orbital fat tissue from the posterior aspect of the eyeball. It is a potential space that can be enlarged by inflammatory fluid (as in posterior scleritis) or infiltrated by extraocular extension of intraocular tumors (as in uveal melanoma) (hintschich and rose 2005). 

Recent studies on mitochondrial structure have demonstrated the localization of mitochondrial enzymes in two membranes and two potential spaces (Fig. 4). For a substrate to react with an enzyme located in the mitochondrial matrix, it must first penetrate both outer and inner membranes. The outer membrane does not appear to hinder the passage of small molecules and substrates. The inner mitochondrial membrane, more analogous to the lysosomal membrane, is relatively impermeable to small molecules and ions (Chappell and Crofts, 1966). For anionic substrates to reach the matrix dehydrogenases, specific transporting systems are present in the inner mitochondrial membrane. Even for diose enzymes located in the inner membrane, penetration of that structure must occur as the active center of such enzymes is only available from the matrix side of the membrane (Chappell, 1968). Such data demonstrate that the presence of a membrane does not in itself induce enzyme latency as creatinine kinase and adenylate kinase localized in the intermembrane space, do not show latency. Moreover, monoamine oxidase and NADH cytochrome c reductase, present in the outer mitochondrial membrane, do not show latency.
