Hydrogen adsorption on rhodium (311) leads to a sequence of ordered superstructures: (1 × 3)-H, (1 × 2)-H, (1 × 3)-2H and (1 × 2)-2H rec . A complete phase diagram of this adsorption system was derived from the development of LEED beam profiles and integral intensities as ...
An explanation for the phase diagram of the H/Ni(111) system is proposed, where the existence of the p(2×2) phase is assumed in addition to the (2×2) phase. Using the position-space renormalization-group theory with prefacing transformation, a lattice gas on a honeycom lattice, includ...

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature, and also provide the pressure ...
(beyond 340 K) as calculated by the Fourier transform of the velocity autocorrelation function. The flat-rhombic phase is characterized by two distinct vibrational bands for hydrogen bonded and dangling O–H bonds, and clear features for the librational modes. On the other hand, the rotations...

Hydrogen adsorption leads to a number of five commensurate phases, namely 1 × 3-H (θ = 0.33), 1 × 2-H (θ = 0.5), 1 × 3−2H (θ = 0.66), 1 × 2−2H (θ = 1) and 1 × 1−2H (θ = 2). Low-energy electron diffraction (LEED) combined with thermal desorption sp...
Typical isothermal phase diagram for an aqueous polymer two-phase system formed by compounds C1 and C2 (see text). Many phase system properties, such as phase interfacial tension, vary with system XY tie-line length (TLL). Examples of this are shown in Fig. 12.7A and B in regard to PEG...
The possible existence of a combined LCST and UCST phase diagram in hydrogen bonding polymer blends has been predicted by Painter and co-workers,41, 46 who modified the FH theory by adding a free energy contribution term arising from strong hydrogen bonding between electron donor and acceptor ...
