Photolysis of fumonisin B1 under simulated solar irradiation in aquatic environment [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2023
Given that the presence of fumonisin as a potentially carcinogenic com­pound in the aqueous medium was confirmed, it is very important to find a method for its effective removal. In this study, the degradation efficiency of fumonisins in aqueous

Modeling of photolysis rates over Europe: impact on chemical gaseous species and aerosols [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
This paper evaluates the impact of photolysis rate calculation on simulated European air composition and air quality. In particular, the impact of the cloud parametrisation and the impact of aerosols on photolysis rates are analysed. Photolysis rates are

Comparison of the RADM2 and RACM chemical mechanisms in O3 simulations: effect of the photolysis rate constant

open access: yesScientific Reports, 2021
Since the photolysis rate plays an important role in any photoreaction leading to compound sink and radical formation/destruction and eventually O3 formation, its impact on the simulated O3 concentration was evaluated in the present study. Both RADM2 and

Photolysis of the Insensitive Explosive 1,3,5-Triamino-2,4,6-trinitrobenzene (TATB)

open access: yesMolecules, 2021
The explosive 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) is of particular interest due to its extreme insensitivity to impact, shock and heat, while providing a good detonation velocity.

Laser Photolysis of Bilirubin [PDF]

open access: yesPediatric Research, 1981
Photodegradation of bilirubin in vitro has been investigated by using monochromatic light supplied by an argon ion laser selecting the 457.9, 488.0 and 514.5 nm wavelengths. Bilirubin was examined in chloroform, in aqueous solutions and in human serum under different experimental conditions of concentration, laser power and time of irradiance ...
