Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Recently, we established a theoretical model for calculating the surface tension: γ= φ^(-1 ) (Vs/V)kT ((0.0481 Es)/RT) where V or Vs= M/ρ and φ= √3/2 〖((√2 Vs)/N)〗^(2/3)
where M is the molar mass, ρ is the density, N is the Avogadro's number (6.02 · 1023 atoms/mol), γ is the surface tension (mJ m− 2), k is the Boltzmann constant (1.38 · 10− 23 J K− 1),R is the universal gas con- stant (8.31 J K− 1 mol− 1), T is the absolute temperature (K), V and Vs are the molar volumes at any temperature and at the melting point (cm3 mol− 1), respectively, φ is the area occupied (cm2 atom− 1) and Es is the heat of sublimation. - GLP compliance:
- not specified
- Type of method:
- other: calculation based on theoretical model and check with reported data
