Recent density-functional theory (DFT) calculations raised the possibility that diamond could be degenerate with graphite at very low temperatures. Through high-accuracy calorimetric experiments closing gaps in available data, we reinvestigate the relative thermodynamic stability of diamond and graphite. For T < 400 K, graphite is always more stable than diamond at ambient pressure. At low temperatures, the stability is enthalpically driven, and entropy terms add to the stability at higher…

TLDR
The flexibility of doped GYs’ electronic and magnetic features recommends them for new electronic and optoelectronic applications, and synthetic strategies that consider numerous chemically and dimensionally different structures are discussed.

TLDR
The relative stability of graphite and diamond is revisited with hybrid density functional theory calculations and graphite gains thermodynamic stability over diamond at 298 K only because of the differences in the zero-point energy, specific heat, and entropy terms for both polymorphs.
A revised diamond-graphite transition curve
Abstract The transition from diamond to graphite is a key equilibrium for interpreting ultrahigh-pressure metamorphic rocks. Despite widespread interest, there remain significant systematic
The Specific Heat of Graphite from 13° to 300°K
The specific heat of high‐purity Acheson graphite prepared by the National Carbon Company has been measured from 13° to 300°K. In the region 13° to 54°K the Cp data follows a T2 dependence quite
Specific Heat of Diamond at Low Temperatures
Specific heat data on diamond at temperatures between 20° and 300°K are reported. Comparisons of the data have been made with the predictions of the Debye theory. The deviation of the specific heat
Heat Capacity of Diamond at High Temperatures
The enthalpy of gem diamonds has been measured from 273° to 1073°K using a ``drop'' method and a Bunsen ice calorimeter. The derived heat‐capacity values, which are believed to be accurate to ±0.5%,
The heat capacity of diamond between 12·8° and 277°k
Abstract The heat capacity of 160 g of diamonds has been measured in the temperature range 12·8° to 277°k with estimated accuracies of ±20% at 13°k, ±6% at 20°k, ±0·8% at 100°k and ±0·2% for T200°k.
