The dispersion state and the efficiency of mixture different components in a composite film have an important impact on its mechanical optical properties. In present work, impacts treatments disaggregation fibrous clay particles water, properties related cellulose nanofiber (CNF)-based films, were evaluated. X-ray diffraction studies, performed samples sepiolite palygorskite, revealed only mino...

In this work, scanning electron microscopy (SEM), X-ray diffraction (XRD), and infrared spectroscopy (FTIR) techniques were used to study blue, red, ochre pigments from wall paintings of the 16th century colonial convent San Nicolás de Tolentino in Actopan, Hidalgo, Mexico. blue pigments, nanometric fibers with a chemical composition mostly O, Si, Al, Mg identified. XRD FTIR analysis indicated ...
