1. Layered Zinc Hydroxide Salts Intercalated with Anionic Surfactants and Adsolubilized with UV Absorbing Organic Molecules
Two anionic surfactants, dodecylsulfate (DDS) and dodecylbenzenesulfonate (DBS), were intercalated into layered zinc hydroxide salts (LHS) using the direct alkaline co-precipitation method, and characterized by powder X-ray diffraction (PXRD), Fourier-transform infrared (FTIR) and thermogravimetric analysis/differential thermal analysis (TGA/DTA).

3. Redução eletroquímica de cinamatos de metila orto-substituídos / Electrochemical reduction of ortho-substituted methyl cinnamates
The synthesis and electrochemical reduction in DMF of some ring substituted cinnamic esters are described. The main objective if this work is to verify the influence of the substituents on the electrohydrodimerization (EHD). The substrates studied were the methyl esters of o-methyl- (1), o-chloro- (2), o-nitro- (3), m,p-dichloro- (4), m-chloro- (5), p-chloro

4. Amine-catalyzed hydrolyses of cyclodextrin cinnamates
Hydrolyses of β-cyclodextrin cinnamate (βCDC) and α-cyclodextrin cinnamate were catalyzed by amines such as 1,4-diazabicyclo(2.2.2)octane, triethylamine, quinuclidine, piperidine, diisobutylamine, and n-butylamine. The rate constant of hydrolyses of the βCDC-amine complexes follows the order: 1,4-diazabicyclo(2.2.2)octane > n-butylamine > quinuclidine >

5. Identification of a common chemical signal regulating the induction of enzymes that protect against chemical carcinogenesis.
Carcinogenesis is blocked by an extraordinary variety of agents belonging to many different classes--e.g., phenolic antioxidants, azo dyes, polycyclic aromatics, flavonoids, coumarins, cinnamates, indoles, isothiocyanates, 1,2-dithiol-3-thiones, and thiocarbamates. The only known common property of these anticarcinogens is their ability to elevate in animal
