Simulating atmospheric composition over a South-East Asian tropical rainforest: performance of a chemistry box model [PDF]

, 2010
Atmospheric composition and chemistry above tropical rainforests is currently not well established, particularly for south-east Asia. In order to examine our understanding of chemical processes in this region, the performance of a box model of ...

Estimating European volatile organic compound emissions using satellite observations of formaldehyde from the Ozone Monitoring Instrument [PDF]

, 2010
Emission of non-methane Volatile Organic Compounds (VOCs) to the atmosphere stems from biogenic and human activities, and their estimation is difficult because of the many and not fully understood processes involved.

Formaldehyde production from isoprene oxidation across NO_x regimes [PDF]

Atmospheric Chemistry and Physics, 2016
The chemical link between isoprene and formaldehyde (HCHO) is a strong, nonlinear function of NOx (i.e., NO + NO2). This relationship is a linchpin for top-down isoprene emission inventory verification from orbital HCHO column observations. It is also a

Global and regional impacts of land cover changes on isoprene emissions derived from spaceborne data and the MEGAN model [PDF]

Atmospheric Chemistry and Physics, 2021
Among the biogenic volatile organic compounds (BVOCs) emitted by plant foliage, isoprene is by far the most important in terms of both global emission and atmospheric impact. It is highly reactive in the air, and its degradation favours the generation of

Bacterial degradation of poly(trans-1,4-isoprene) (gutta percha) [PDF]

Microbiology, 2007
Gutta percha, the trans-isomer of polyisoprene, is being used for several technical applications due to its resistance to biological degradation. In the past, several attempts to isolate micro-organisms capable of degrading chemically pure poly(trans-1,4-isoprene) have failed. This is the first report on axenic cultures of bacteria capable of degrading

The microbiology of isoprene cycling in aquatic ecosystems [PDF]

, 2021
Isoprene (2-methyl-1,3-butadiene) is emitted in vast quantities (>500 Tg C yr-1). Most isoprene is emitted by trees, but there is still incomplete understanding of the diversity of isoprene sources.
