The C-matrix: Augmentation and reduction in the analysis of chemical composition and structure

Chemical Engineering Science, 2014
Abstract We propose a unified linear-algebraic approach that allows determining the three key matrices of chemical kinetics: molecular, stoichiometric and Horiuti matrix, all within a single procedure. This procedure is based on calculating a so called C-matrix, which is obtained from each matrix by augmenting it with a unit matrix and then reducing ...

Analysis of Initial Reactions of MALDI Based on Chemical Properties of Matrixes and Excitation Condition

The Journal of Physical Chemistry B, 2012
This investigation concerns the initial chemical reactions that affect the ionization of matrixes in matrix-assisted laser desorption/ionization (MALDI). The study focuses on the relaxations of photon energy that occur on a comparable time scale to that of ionization, in which the available laser energy is shared and the ionization condition is changed.

E.s.c.a. (electron spectroscopy for chemical analysis) Analysis) study of monomodal metal phases in a faujasite X matrix

Zeolites, 1982
A series of faujasite supported catalysts with monomodal dispersed phases of nickel, palladium, and platinum, exhibiting narrow particle size distributions, are chracterized by X.p.s. (X-ray photoelectron spectroscopy).

Microwave-assisted retting and optimization of the process through chemical composition analysis of the matrix

Industrial Crops and Products, 2014
Abstract Pre-soaked flax stems were subjected to microwave assisted retting at different power levels and the effectiveness of microwave assisted retting was studied through the analysis of chemical compounds presented in the retted flax fibers processed from the stems. Response surface statistical design was used for this study with JMP® 10 software.
