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 ...
From the calculated energetics we make a model calculation of the phase diagram of hydrogen in palladium in qualitative agreement with experiment. On this ... OB Christensen,P Stoltze,KW Jacobsen,... - 《Physical Review B Condensed Matter》 被引量: 40发表: 1990年 Solubility of hydrogen in Pd...
Phase diagram of hydrogen adsorbed on Ni(111) 来自 Elsevier 喜欢 0 阅读量: 5 作者: K.,Nagai 摘要: 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-...

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 ...
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 in the hexatic-like phase merge the two stretching bands into a doublet, and smear out the fine structure of the lib...
A (T-P) phase diagram of hydrogen storage on (N4C3H)6Li6. Temperature-pressure phase diagrams are generated through the study of hydrogen adsorption on the (N(4)C(3)H)(6)Li(6) cluster at the B3LYP/6-31+G(d) level ... R Das,PK Chattaraj - 《Journal of Physical Chemistry A》...
Low-energy electron diffraction (LEED) combined with thermal desorption spectroscopy (TDS) were used to investigate the phase diagram of hydrogen on Rh(110) in the temperature range of 35–220 K. To study the growth and disordering of the different commensurate phases we analyzed beam profiles ...
材料导论15_相相图(PhasesPhaseDiagrams).ppt,2.3.1 Phases 1) Phase: a homogeneous part or aggregation of material that differs from another part due to difference in structure, composition, or both. Example: Water: made up of hydrogen and oxygen (same co
In addition, we estimate the melting temperature of the hydrogen sublattice. As we will discuss later, the solid to FCC-SI phase transition has a sharp change in the conductivity at the melting temperature and thus we can use the conductivity to locate the transition temperature. However, the...
