The resonant timesteps of order n m (where n and m axe integers), correspond to a sampling of n phase-space points in m revolutions. This condition implies that...

Depending on the R group, this reaction could lead to the formation of gold(I) isocyanide complexes that behave as liquid crystals. Thus, complexes [Au(C6F5) (C = N(QH4)OCioH2i-p)] and [Au(QF5)(C = N(QH4)OCnH2n + rP)] [64] where n = 4, 6, 8, 10 and 12 show this behavior. All of these complexes are mesomorphic and behave as liquid crystals showing a nematic (N) phase when the isocyanide has a... 

Derivatives of aliphatic alkynes (14 and 15) are more thermally unstable than 12, but they show SmA and N phases at low temperatures (below 130 °C). The type of phase and the mesophase stability depend on the length of both the terminal and the lateral chains. When both chains are elongated, the mesomorphism becomes metastable and compounds 14 display monotropic N and SmA transitions. Complexes IS, which contains an ester group with an opposite direction to that of complexes 14, display less stable nematic mesophases. 

More complex phenomena occur when current crosses interfaces between semiconductors. The most typical example is the rectification produced at interfaces between p- and n-type semiconductors. Electric current freely flows from the former into the latter semiconductor, but an electric field repelling the free carriers from the junction arises when the attempt is made to pass current in the opposite direction Holes are sent back into the p-phase, and electrons are sent back into the n-phase. As a result, the layers adjoining the interface are depleted of free charges, their conductivities drop drastically, and current flow ceases ( blocking the interface). 

Commercially available Apiezon greases are usually orange colored prior to cleanup and colorless afterwards. Exhaustive hydrogenation can be used to saturate aromatic and olefinic groups to produce a more stable product, Apiezon MB, having properties more typical of a saturated hydrocar]x>n phase [18].. ... 

Of crucial significance in deciding between various models have been estimates of the number of copper atoms required to transform the surface into a (2 x 3)N phase. This was the approach adopted by Takehiro et al 2 in their study of NO dissociation at Cu(110). They concluded that by determining the stoichiometry of the (2 x 3)N phase that there is good evidence for a pseudo-(100) model, where a Cu(ll0) row penetrates into the surface layer per three [ll0]Cu surface rows. It is the formation of the five-coordinated N atoms that drives the reconstruction. The authors are of the view that their observations are inconsistent with the added-row model. The structure of the (2 x 3)N phase produced by implantation of nitrogen atoms appears to be identical with that formed by the dissociative chemisorption of nitric oxide.

We consider a molten multi-mineral assemblage, referred to as the source, which is presumed to give rise to an erupting magma. X is the mass-fraction of each phase j relative to the molten source (and not to the residue). Subscript j= 1 refers to the melt, j = 2,..., n to the n — 1 residual mineral phases. The sum of the Xj over all the n phases is unity. If Cliq is the concentration of the ith among m elements in the liquid, the concentration of element i in phase j will be K/C,iq . Let C0 be the concentration of i in the source prior to melting. Hence, mass balance requires... 

Let us consider the behavior of the ith among m trace elements upon partitioning between a homogeneous liquid (labeled liq) and the n phases (labeled j) of the cumulate in a system of finite size. These phases are usually considered as mineral phases but liquid trapped in the cumulate can be handled as an additional phase with partition coefficients equal to unity (Greenland, 1970 Albarede, 1976). 

Consider, for example, a sensor composed of n phases each with a different nonradiative decay rate. The fraction of the excited sensor molecules Pi in phase ith may decay with an overall decay rate kr + k ri. In this case, the average probability of the sensor molecules of remaining in the excited state is given by... 

The phase diagram of an electrode material may be determined from the slope of the coulometric titration curve. An electrode of N components shows activities which are independent of the composition as long as the maximum number of N phases are in equilibrium with each other. Relative changes in the amounts of the different phases do not change the activities of the components and therefore keep the cell voltage constant. This causes voltage plateaux for any region of the equilibrium of the maximum number of phases.

These arguments may be extended to an -compositional space the straight paths will be replaced by planes in a three-component system, by hyperplanes in a four-component system, and so on. Moreover, in an -component system at fixed P and T, no more than n phases may be stable at the same P-T-Xcondition, and their compositions are uniquely determined at any combination of P, T, and X.
