As early as 1905, the German physicist Pawlow [16] predicted that the melting point of solid would depend on the size of its particles, and derived a quantitative formula to describe the requisite melting point variation. Hanszen, another German physicist, modified Pawlow’s formula in 1960 [...
A simple formula for the calculation of the melting point is derived. It can be formally split into melting enthalpy and entropy. Thus, a description of the lattice's long-range order is gained. This formula can also be integrated into a computational tool and used as an automated batch ...
The starting point is that On the one hand On the other hand we have the standard fluctuation formula Combining these equations at the reference state point leads to (where subscript 0 denotes an equilibrium average at the reference state point) Consider next an arbitrary temperature T on the ...
When a substance melts from solid to liquid, it does so at a precise and constant temperature, called it melting point. All the heat it absorbs does not change its temperature at all, but is instead being used to break its bonds. Solids are v...
Approximately 3.6 billion years ago, most of Mars' water was likely frozen in large southern ice sheets and Mars' atmosphere had thinned to the point that it began to collapse, periodically forming a massive south polar CO2ice cap. I model the thermal blanketing effect of the CO2ice cap over...
12-b) are characterized by the end of the process, for the middle point, around the end of the analysis period. This can be considered the optimal conditions, even if the bottom layer of the PCM does not reach the liquid phase, as the middle layer is representative of the overall layer...
The estimated pressure and temperature of formation of the YAMM basalts allow us to place further constraints on the mantle potential temperature for the Moon and its plausible evolution following the approach of Filberto and Dasgupta67,68. The calculation was performed first by evaluating the percent...
The calculation results are saved every 10 minutes in the early stage of ice-snow melt water and every 30 minutes in the middle and later stages, with the pore water pressure at the monitoring point recorded in real time simultaneously. This paper analyzes the stability of the slope. The ...
. . . In absence of interactions, we review the exact lattice calculation of several conserved quantities, including e.g. the magnetization and the spin current profiles. At large distances x and times t, we show how these quantities allow for a ballistic scaling behavior in terms of the ...
Tm values obtained by this calculation correlate very well with the values determined empirically at room temperature using conventional UV hypochromism and a conventional Hewlett-Packard diode array spectrophotometer (scanning rate of about +1° C./min.) for a solution of oligonucleotide (primer or...
