1. ADSORÇÃO DE 5 FLUOROURACIL E 5 CLOROURACIL SOBRE HOPG: um estudo da importância do estado de protonação via microscopia de varredura por tunelamento. / ADSORPTION OF 5-FLUOROURACIL AND 5 CLOROURACIL ON HOPG: a study of the importance of the state of protonation via scanning tunneling microscopy.
Neste trabalho foi explorada a adsorção de moléculas orgânicas para realizar modificação em superfícies. Neste contexto foi proposta a adsorção das moléculas orgânicas de derivados halogenados do uracil, o 5 Fluorouracil e o 5 Clorouracil no, substrato monocristalino do HOPG (Grafite Pirolítico Altamente Orientado do inglês, Highly Oriented Pyro

2. Free radicals formed by exposure of pyrimidine solids to sodium atoms: an electron spin resonance study.
Sodium atoms have been deposited on various pyrimidine powders under high vacuum at 77 degrees K and the electron spin resonance spectra of the resulting free radicals have been observed. Generally, the spectra show that the electron of the Na goes into a molecular orbital of the pyrimidine ring and the Na+ ions become attached to a carbonyl oxygen of the re

3. Lethal and Mutagenic Effects of 5-Iodouracil on Bacteriophage T4td8rII
Evidence was obtained which indicates that the lethal effect of 5-iodouracil (IUra) on bacteriophage T4 is not due to a mutagenic process. T4td8rII (thymine requiring, rapid lysis) double mutants were constructed. Reversion of T4td8rII to r+ was measured. First, reversion by growth in the presence of the structural analogues chlorouracil (ClUra) and bromoura
