In this paper, we report the photodegradation of three different chlorine photosensitizers (Photoditazine (R), Radachlorin (R), and Foscan (R)). The photosensitizer degradation was analyzed by changes in the fluorescence ...

Commercial TiO2 nanoparticles were superficially modified through polymeric resins obtained from polymerization of citrate complexes of Y3+ and Al3+ with ethylenglycol. The materials were treated at 450 A degrees C for 4 ...

Nitrendipine produces a well-defined polarographic peak due to the four-electron reduction of the nitro group. This peak is used for tracking the photodecomposition of nitrendipine in both UV light and daylight conditions. ...

Poly(p-phenylene vinylene) (PPV) derivatives are an important class of conjugated polymers, known for their applications as electroluminescent materials for light-emitting devices and sensors. These derivatives are highly ...

The application of nanostructured titanium dioxide (TiO 2 ) as catalyst for the photodegradation of drugs and dyes is well established. We aimed to evaluate the importance of the reactivity of aromatic compounds submitted ...
