In addition to product isomers, the crossed beam technique also provides information on the highly unstable reaction intermediates. The identified intermediates have been characterized by resorting to ah initio electronic structure calculations all the reaction intermediates are doublet radicals, internally excited, and hence highly reactive in planetary atmospheres. Although under the experimental single collision conditions the gas is too rarefied to allow three-body collisions, the collision induced stabilization of the intermediates is possible in Titan s dense atmosphere. Notably, these free radicals have unknown spectroscopic properties which could make them responsible for the orange color of the upper atmospheric layers. 

Green, iron-rich structures called rusticles growing from the sunken hull of RMS Titanic are gradually destro5ung what remains of the ship. Rusticles contain colonies of metallophilic bacteria the structures are composed externally of lepidocrocite, y-Fe(0)0H, and internally of goethite, a-Fe(0)0H. The rate at which the bacteria are converting the ship s hull into rusticles is alarming and the phenomenon is a topic of current research.

One of the first ships capable of crossing the Atlantic, the Great Eastern, had many safety features designed into her structure. Built in 1859, she was by far the largest ship ever built at that time. On one of her voyages she hit a rock that made a hole in the hull thought to be 60 times the area of the one in the Titanic. Yet her internal bulkheads were so extensive and strong that she hardly even listed.
