1. Propriedades fotoquímicas e fotofísicas de novos materiais derivados quinolinas e di naftalimidas / Photochemistry and photophysical properties of new materials derivatives of quinolines and Di-naphtalimides
Excited state proto transfer reactions in aqueous media is among current themes in photochemistry research. Shortly, organic molecules having acid or basic groups and presenting excited state lifetimes long enough, competitive prototropic reactions can occur. This phenomenon is attributed to an isoelectronic state of the ground state molecule and up to seven

2. Aplicação de modelos simples em fenômenos envolvendo monocamadas e micelas / Application of simple models in monolayers and micelles
O presente estudo versa sobre a proposição ou extensão de modelos simples para descrever os seguintes fenômenos envolvendo agregados anfifílicos: i-) Influência de sal na concentração micelar crítica (CMC) e número médio de agregação () de micelas zwitteriônicas. ii-) Influência da interação eletrostática (neste caso, repulsiva) e tamanho d

3. Sintese fotoquimica de polipirrol em membranas microporosas de PVDF : um novo metodo para obter compositos condutores eletricos
This work outlines a new method to obtain conducting composites of Polypyrrole (PPy)/Poly(vinilydene Fluoride) (PVDF), via UV-ligth induced Polymerization in presence of suitable a Photoacid Generator (PAG) compound such as Iron-arene and Triphenyl Sulfonium salts or organic PAG compound such as chlorinated triazines. Gravimetric and Thermal Gravimetric Anal

4. Effects of stray light on the fidelity of photodirected oligonucleotide array synthesis
Fabrication of high density oligonucleotide arrays using metal on glass photolithographic masks is inflexible and expensive. Maskless methods using computer-controlled projection have been proposed and implemented, but associated stray light effects on photodirected oligonucleotide synthesis and their analysis have not been reported. We have developed a theo
