In this work was investigated the surface modification of PP films treated by corona discharge through FTIR/ATR spectroscopy (chemical structure), contact angle goniometry

Zinc volume diffusion coefficients and zinc grain- boundary diffusion coefficients in ZnO were meas- ured by means of the residual activity method using the 65 Zn as zinc tracer.

• In our experimental conditions, oxygen volume dif- fusion in Li-doped ZnO is similar to the oxygen vol- ume diffusion in pure ZnO, but oxygen volume diffu- sion in Al-doped ZnO

On the other hand, the AISI 304 steel has the same oxidation behaviour in both atmos- pheres, at 850 °C, but, at higher temperatures, its oxi- dation rate dramatically increases

Therefore, to understand the behavior of fillers, such as carbon black, silica and mica added to castor oil-derived polyurethane resins, several thermal, mechanical and electrical

For the calculation of the moment of failure is used a theoretical model, which considers the plastic elastic behavior of wood, subjected to compression loads and the fragile

Este com- portamiento sería diferente al que se presentaría para pH < 6.5 donde la hidrólisis del Co(II) sería inducida por grupos superficiales más que por la acidez de la

The average voltametric roughness, R v , is apparently not dependent on zirconia and mullite phase concentrations in the case of fracture surfaces of the
