Internal combustion

, : Internal combustion. Nature 426: 8-9

In a recent article, Anala et al. (J. Am. Chem. Soc. 2003;125:13298-302) demonstrate the potential of NMR to study combustion reactions and transport in opaque media. In situ experimental observations of combustion are difficult in opaque environments. By preparing xenon gas so that individual atoms had angular momenta characteristic of extremely low temperatures and then delivering the gas to the NMR experiment at ambient temperatures, Anala et al. were able to detect NMR signals from xenon atoms in a methane flame burning inside a porous material. The researchers' measurements revealed varying zones of temperature and pressure within the flame. Although further research is required to extend the strategies presented by Anala et al., NMR techniques have huge potential in the characterization of catalytic combustion.

Encouraging results have been obtained with transit time models in ruminants but problems arise if these models are applied to horses. One reason for such discrepancies might be underestimating the role of feedback mechanisms occurring between the...
