Effects of UV Radiation on Paper: A Chromatic Study
Melania Jiménez-Reyes, Dolores Tenorio, Genoveva García-Rosales, Jaime Jiménez-Becerril, Gabriel Edgar Luna-Castro
A study on Whatman#1, bond, rice, kraft, and amate papers in their original condition and exposed to 2.25, 4.5, 6.75, and 9 W of Ultraviolet-C radiation is presented. No changes were found in these papers, length and width of fibers, chemical composition, pH, pyrolysis characteristics, or FTIR and XRD patterns after irradiation.
Synthesis, Isolation and Characterization of three acid and alkaline hydrolytic products of Nimodipine and Development of a valid RP-HPLC method for simultaneous determination of Nimodipine and Citicoline sodium in the presence of Nimodipine degradation products in Bulk and Tablets
Ayman Abo Elmaaty Mohamed
In this study, three degradation products of nimodipine were synthesized, isolated and characterized with aid of FTIR spectroscopy, 1H-NMR as well as LC-MS/MS after exposing to drastic acidic and alkaline conditions.
Multi-Element Determination of Trace Elements in B7-diesel Oil by High-Resolution Continuum Source Flame Atomic Absorption Spectrometry
Heldiane S. dos Santos, Alexandre de Jesus, Diane O. Laroque, Clarisse M. S. Piatnicki, Márcia M. da Silva
In this work, a method for sequential multi-element determination of Cu, Fe, Ni, Pb, Zn, Al, Cr and Sn in B7-diesel oil samples by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS) was proposed.
