In order to gain more information regarding photochemical processes in heterogeneous
environments (opaque or powdered samples) laser induced time resolved luminescence …

Using ionizing radiation to initiate polymerizations leads to random formation of active
centers that is difficult to characterize and predict. Secondary reactions further complicate …

Unfunctionalized graphene is positively or negatively charged when it is dispersed in
organic solvents. The charging is negative in solvents with high electron donor numbers and …

This paper introduces a facile approach to synthesize a nano-structured light stabilizer
composed of a typical ultra-violet absorber (UVA) and graphene oxide (GO) nano-sheets …

Diffuse reflectance and laser-induced techniques were used to access photochemical and
photophysical processes of benzil in solid supports, namely p-tert-butylcalix [n] arenes with …

Alkylperoxyl and alkoxyl radicals absorb only in the UV region, whereas vinylperoxyl,
phenylperoxyl, alkylthiylperoxyl and benzyloxyl radicals have strong absorptions in the …

Diffuse reflectance and laser-induced techniques were used to study photochemical and
photophysical processes of benzil adsorbed on two solid powdered supports …

A new procedure for the direct study of the chemical reactivity of acrylate radicals is
developed: the acrylate radicals are produced by the addition of an aminoalkyl radical to an …

Pyridine ketones have recently been found to be suitable α-cleavage photoinitiators for
radical polymerization with excellent water solubility. Nanosecond time-resolved laser flash …

Sensitized photoreduction of Ag+ ions and subsequent formation of colloidal Ag
nanoparticles occur when near-UV light is irradiated onto the ethanol solution of a mixture of …
