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 ...

Photolysis of Diborane at 1849 Å [PDF]

open access: yes, 1962
The photolysis of diborane at 1849 Å has been studied in a specially constructed, internal‐type mercury‐vapor lamp. The products have been found to be H_2, B_(4)H_(10), B_(5)H_(11), and, at low pressures, a —BH— polymer.

Ultraviolet B (UVB) Photosensitivities of Tea Catechins and the Relevant Chemical Conversions

open access: yesMolecules, 2016
Ultraviolet B (UVB) photosensitivities of eight catechins were screened. In both water and ethanol, epicatechin (EC, 575 μM) and catechin (C, 575 μM) exhibited low photostabilities under 6 h UVB radiation with the generation of yellow photoproducts ...
