  2010 SEP 3 - (VerticalNews.com) -- "A general approach is proposed to elucidate the topological characteristics of molecules with the shape of polyhedral links," scientists in Lanzhou, People's Republic of China report.

  "For an arbitrary polyhedral graph, four classes of polyhedral links can be obtained by applying the operation of 'X-tangle covering' to the related reduced sets. The relationships between the W-polynomial of a polyhedral graph and the HOMFLY polynomial of each kind of polyhedral links are established," wrote S.Y. Liu and colleagues, Lanzhou University ...read more

  2010 APR 13 - (VerticalNews.com) -- "Although the Morse potential function is widely used in molecular modeling software, newer potential functions that possess more parameters provide greater accuracy. Against this backdrop, the Four-Parameter-Diatomic-Potential (FPDP) was selected for converting its parameter into those of the Morse potential due to the former's resemblance to the latter," investigators in Singapore, Singapore report ...read more

  2010 APR 13 - (VerticalNews.com) -- According to recent research published in the Journal of Mathematical Chemistry, "In this paper, a sequence of approximate solution converging uniformly to the exact solution for a class of integro-differential equation with an integral boundary condition arising in chemical engineering, underground water flow and population dynamics and other field of physics and mathematical chemistry is obtained by using an iterative method. ...read more
