X-ray peak broadening analysis in LaMnO3+δ nano-particles with rhombohedral crystal structure
In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...
متن کاملXenon and krypton separation in a chromatographic column packed with granulated nano NaY zeolite
In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...
متن کاملA Sensitive Liquid Chromatographic Method for the Analysis of Clarithromycin with Pre-Column Derivatization: Application to a Bioequivalence Study
Objective(s) A sensitive liquid chromatographic method for the analysis of clarithromycin- a macrolide antibiotic- in human serum, using pre-column derivatization with 9-fluorenylmethyl chloroformate (FMOC-Cl) is described. Materials and Methods The method involved liquid-liquid extraction of the drug and an internal standard (amantadine) followed by pre-column derivatization of the analytes...
متن کاملOn the Mechanisms behind Chaos
Chaotic systems are observed everywhere. Electronic circuit analogues based on the differential equations of the models for the chaotic systems are often used to study the nature of chaotic systems. This tutorial is an attempt to classify electronic chaotic oscillators according to the mechanism behind the chaotic behaviour, e.g. one group is based on the sudden interrupt of inductive currents ...
متن کاملAnalysis of Factors Causing Peak Broadening in Capillary Zone Electrophoresis
An equation analogous to the Van Deemter equation in chromatography is developed to account for peak broadening in capillary zone electrophoresis (CZE). This equation applies to conditions where the peaks are symmetrical (sample zone concentration much less than background electrolyte concentration). To identify and to quantitate the effects of different contributors to the peak width in CZE, i...
