A novel profluorescent dinitroxide for imaging polypropylene degradation [PDF]
, 2008 Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades.

Survival of Organic Materials in Hypervelocity Impacts of Ice on Sand, Ice, and Water in the Laboratory [PDF]
, 2014 The survival of organic molecules in shock impact events has been investigated in the laboratory. A frozen mixture of anthracene and stearic acid, solvated in dimethylsulfoxide (DMSO), was fired in a two-stage light gas gun at speeds of ?2 and ?4?km s?1 ...

Ethyl anthracene-9-carboxylate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the title compound, C(17)H(14)O(2), the COO group and the anthracene fragment form a dihedral angle of 76.00 (19)°. The torsion angle around the O-Csp(3) bond of the ester group is 108.52 (18)°. The crystal structure is stabilized by C-H⋯O inter-actions and edge-to-face arene inter-actions with C-H⋯(ring centroid) distances in the range 2.75-2.84 Å.
