1. Estudo e projeto de reatores fotoquimicos para tratamento de efluentes liquidos / Study and design of photochemical reactors to treat liquid effluents
Wasterwater treatment has become a fundamental stage of industrial processes. Most wastewater treatment are currently based on biological processes. However, some types of wastewater cannot be treated by such processes due to the fact of possessing toxic. Therefore, the Advanced Oxidation Process (AOP) can be used with success in such wastewater remediation.

3. Electron transfer in DNA duplexes containing 2-methyl-1,4-naphthoquinone
2-Methyl-1,4-naphthoquinone (menadione, MQ) was linked to synthetic oligonucleotides and exposed to near-UV light to generate base radical cations in DNA. This model system of electron transfer induced alkali-labile breaks at GG doublets, similar to anthraquinone and metallointercalators systems. In sharp contrast to other systems, the photolysis of MQ–DNA

4. Photochemically induced cataracts in rat lenses can be prevented by AL-3823A, a glutathione peroxidase mimic.
Oxidative stress is known to cause cataracts in lens culture systems and is believed to be an important factor contributing to human cataracts. In this communication, it is demonstrated that cataract development of cultured rat lenses produced as a result of photochemically induced oxidation in a 4% oxygen atmosphere similar to the native environment of the
