Emissions compounds such as formaldehyde (HCHO), acetaldehyde (CH3CHO), and acrolein (H2CHCHO) are of interest to the scientific and regulatory communities due to their suspected or likely impacts on human health. The frequent exhaust products of the two engine operation modes were, acetaldehyde ...
suggesting a potentially important role for formaldehyde as a cause of cancer induced by cigarette smoking. Chloroacetaldehyde, a metabolite of vinyl chloride, reacts with nucleic acid bases to form four exocyclic DNA adducts: 1,N6-dA; 1,N2-dG;N2,3-dG; 3,N4-dC. Both 1,N6-dA andN2,3...
to estimate the impact of aldehyde emissions at an airport on the air quality, formaldehyde and acetaldehyde concentrations were measured in the idle and t... CS Guimarães,LS Varandas,G Arbilla - 《Journal of the Brazilian Chemical Society》 被引量: 5发表: 2010年 Simulation of Aldehyde Emis...

The addition of FA or AA induces the conversion of [Ag(NH3)2] +complex to silver nanoparticles (AgNPs) because of aldehyde-induced silver reduction reaction. The AgNPs possess strong SERS activity. The average interparticle gaps between the AgNPs can be fine-tuned by controlling the experimental...

The addition of FA or AA induces the conversion of [Ag(NH3)2]+ complex to silver nanoparticles (AgNPs) because of aldehyde-induced silver reduction reaction. The AgNPs possess strong SERS activity. The average interparticle gaps between the AgNPs can be fine-tuned by controlling the experimental...
Evidence of C C bond dissociation is given by formaldehyde desorption during UV-acetaldehyde-TPD over TiO/CMSF under UHV conditions. Moreover, UV-acetaldehyde-TPD indicated a twofold increase of the reductive coupling product (butadiene). The latter requiring Ti(<4) to be formed translates an...
FORMALDEHYDESILICA GELZEOLITESThe synthesis of acrolein by means of the catalytic vapor phase condensation of formaldehyde and acetaldehyde was studied. Oxides such as ZnO, MgO, MoO 3 , B 2 O 3 and P 2 O 5 , deposited over ZSM-5, Y-faujasite, Al 2 O 3 and SiO 2 , were tested as...
