On a class of approximate formulas for total ח-electron energy of benzenoid hydrocarbons [PDF]
Journal of the Serbian Chemical Society, 2001 The method for obtaining approximate formulas of the (n, m)-type for the total -electron energy of benzenoid hydrocarbons (communicated in J. Serb. Chem. Soc. 54 (1989) 189) is simplified and extended so as to include arbitrary spectral moments.

Atmospheric emissions from the deepwater Horizon spill constrain air-water partitioning, hydrocarbon fate, and leak rate [PDF]
, 2011 The fate of deepwater releases of gas and oil mixtures is initially determined by solubility and volatility of individual hydrocarbon species; these attributes determine partitioning between air and water.
