Characterization and Application of Urea-Formaldehyde-Furfural Co-condensed Resins as Wood Adhesives

BioResources, 2014
Furfural, as an organic compound derived from biomass materials, was used to partially substitute for formaldehyde in the synthesis of UF resin. Urea-formaldehyde-furfural co-condensed (UFFR) resins with different substitute ratios of furfural to ...

Mapping isoprene emissions over North America using formaldehyde column observations from space [PDF]

, 2003
We present a methodology for deriving emissions of volatile organic compounds (VOC) using space-based column observations of formaldehyde (HCHO) and apply it to data from the Global Ozone Monitoring Experiment (GOME) satellite instrument over North ...
