abstract = {FTIR-ATR and XRF techniques have been employed to carry out a preliminary characterization of the cellulose of four postcards issued during the Third Reich war in the East. Two postcards were printed in Berlin while the other two corresponded to communist Russian postcards with German overprints. The XRF results show that only the paper of the German postcards contains potassium. The four postcards present Fe and Cu that could oxidize cellulose. The possible presence of cotton is suggested but not proved.},

abstract = {An infrared, scanning electron microscopy and X-ray fluorescence study was performed on the Spanish book entitled Treated of the True and False Prophecy printed in Segovia during 1588. Three small samples were taken from the margins of three pages. Two of them belong to the original book while the third one is from a page added later during the binding of the book. The first result is that the paper is contaminated with numerous metallic elements. The distribution of these contaminants in the three samples suggests that this process began after the binding of the book. The carbonate moiety of the calcium carbonate seems to have disappeared with the passing of time transformed in carbon dioxide. Al, K and S, components of potassium alum are detected by SEM and XRF analyses. Gelatin seems to be present because some IR bands of proline suggest that. There is an unsolved problem with some IR bands because of the fact that they can be ascribed to two different entities.},

abstract = {Fourteen heavily damaged postage stamps were chosen for an infrared and scanning electron microscopy (SEM) characterization of their non-printed margins. The results show the presence of kaolinite used as filler in all but two samples. These last two contain aluminum (with an Al-OH moiety). One stamp seems to contain barium in the form of sulfate. One stamp contains lead in an unknown chemical compound. All these results were incorporated into a database for future analysis. Quantum chemical calculations of diverse large models of cellulose seem absolutely necessary for the IR band assignments.},
