of thermodynamics, the difference of the Gibbs free energy (ΔG) between the liquid and the crystalline phases can be expressed as: ΔG=ΔH-TΔS ... in the matrix using scanning transmission electron microscopy-electron energy loss spectroscopy (STEM-EELS). Based on these findings, it has been obtained that the accurate chemical compositions......
Heidelberg 2011 Abstract: To further test whether polynitriprismanes are capable of being potential high energy density materials (HEDMs), extensive theoretical calculations were carried out to investigate on a series of polynitrotriprismanes (PNNPs): C6H6-n(NO2)n (n=1-6). Heats of formation (HOFs), strain energies (SE), and disproportionation energy (DE) were obtained using B3LYP/6-311+G(2df, 2p......
in the increase of grain boundary area and enhancement of system free energy. The spacing be tween deformed domains in 96 h milled samples is somewhat smaller than those in 48 h milled samples, indicating...-milling pro cess were characterized. The results showed that there was a clear correlation between the change in TiC powders and that in the PAT parameters. In the high energy ball-milling process, TiC......

The results indicate that specimens show different... to stable status. Expansive deformation of specimen is mainly influenced by the solid phase type and free water content before steam curing (or initial water content). Through choosing a water-binder ratio......
