Excess properties have been worked out taking account for non-ideality of both liquid and vapor phases and compared to the prediction of the average potential theory developed by Prigogine and coworkers (see The Molecular Theory of Solutions , (Amsterdam 1957)) Table I gives the main results. ...
The gas-phase data are correlated with a virial equation of state. The compressed liquid data are fit with an abbreviated form of the modified Benedict-Webb-Rubin (mBWR) equation. A table of thermodynamic properties is presented for the saturated liquid and vapor states. 展开 ...
A molecular dynamics study on the effects of water on the structural and thermodynamic properties of methanesulfonic acid found that an increase in the number of water molecules led to a larger hydrogen bonding network and a higher heat capacity of the system confirming the results obtained in ...
As shown in Table 5, the increase of Co loading amount leads to the improvement of the stability of H2 yield. In addition, it is found that 15% Mo2C/γ-Al2O3 shows higher initial catalytic activity than 15% Mo2C/α-Al2O3. This might be due to the higher surface area of γ-Al2...
2 and Supplementary Table 3). During catalytic ignition, the overall intensity of the O 1s signals decreased with the reduction of nickel. These spectra show that the oxygen species at BE of 529.9 eV (NiOx, O–Ni(s)) was being consumed faster than the species at BE of 531.3 ...
The physical properties of our four studied samples are grain density, bulk density, total pore volume, and total porosity. The results obtained are listed in Table 1. Both the grain density and bulk density values are comparable for four samples. The value of the total pore volume is in ...

Atmospheric methane levels are growing rapidly, raising concerns that sustained methane growth could constitute a challenge for limiting global warming to 2 °C above pre-industrial levels, even under stringent CO2 mitigation. Here we use an Earth sys
