Thermodynamic properties of tungsten

Physical Review B, 1987
Tungsten has several unusual thermodynamic properties, e.g., very high values of the melting point, the entropy of fusion, the expansion on melting and the lattice anharmonicity. These features are given a semiquantitative explanation, based on the electron density of states N(E).

Thermodynamic Properties of Montecellite

Geochemistry International, 2019
A thermochemical study of natural calcium and magnesium orthosilicate ─ monticellite (Ca1.00Mg0.95)[SiO4] (Khabarovsk Territory, Russia) was carried out on the Tian-Calvet microcalorimeter. The enthalpy of formation from the elements fHоel(298.15 K) = -2238.4 4.5 kJ / mol was determined by the method of high-temperature melt solution calorimetry.

Thermodynamic Properties of Na0.65CoO2

Czechoslovak Journal of Physics, 2004
Specific heat of the layered Na0.65CoO2 powder sample over the temperature region of 3-360 K has been studied. Features hinting at charge ordering below room-temperature were observed. Magnetic phase transition at 28 K as well as signs of short-range ordering confirm the 2D character of magnetism with weak inter-planar coupling in the system ...

Thermodynamic properties of superhelical DNAs

Biochemistry, 1975
Binding isotherms of ethidium to the superhelical DNA from phage PM2, and to PM2 DNA containing -1 single-chain scission per molecule, have been determined at six temperatures from 2.5 to 50 degrees, in 3M CsCl-0.01 M Na3EDTA. Spectrophotometric measurements in both the visible and ultraviolet (uv) regions were used to obtain the binding isotherms. The

Thermodynamic Properties of Small Systems

Physical Review, 1961
We investigate the dependence of the pressure of a homogeneous system, at a given density $\ensuremath{\rho}$ and temperature $T$, on the number of particles $N$. The particles of the system are assumed to interact via forces of finite range $a$ and are confined to a periodic cube of volume ${L}^{3}$, $\ensuremath{\rho}\ensuremath{\equiv}\frac{N}{{L ...

Thermodynamic properties of alkali metals

Journal of Physics F: Metal Physics, 1972
The authors have calculated the equations of state at 0 K for the various alkali metals starting from a theoretical description of the volume dependence of their dynamical matrix. They also obtain a detailed knowledge of the individual Gruneisen parameters which allow them to calculate temperature effects like the thermal pressure and the thermal ...
