Substituted proline derivatives as organocatalysts in Michael reaction [PDF]
Journal of the Serbian Chemical Society, 2014 Chiral, polysubstituted proline esters, obtained via cycloaddition reactions of azomethine ylides, have been studied as organocatalysts in Michael reaction of aldehydes/ketones and vinylsulphones. Under optimised reaction conditions employing 10

Hydrodynamic Models for Heavy-Ion Collisions, and beyond [PDF]
, 2000 A generic property of a first-order phase transition in equilibrium, and in the limit of large entropy per unit of conserved charge, is the smallness of the isentropic speed of sound in the ``mixed phase''.
