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.

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.

Infrared Pseudo Matrix Isolation: A Catalog of Spectra for Chemical Analysis [PDF]
, 1970 Spectrometry is becoming increasingly relevant in fuel research. As our consumption of fuels is growing, our concern for the multidisciplinary problems of environmental control becomes more pressing. Here, chemistry is deeply implicated. Fundamental questions remain to be answered, and there is an insistent demand for technological solutions to well ...

Chemical state analysis of ZnO/Ag film interface utilizing the matrix effect
Applied Surface Science, 2003Abstract The degree of oxidization of Ag in the interface of ZnO/Ag has been investigated by utilizing the matrix effect. We monitored various secondary ions (Ag+, CsAg+, Ag−, AgO−) under Cs+ bombardment during the depth profile analysis. It was found that Ag+, Ag−, AgO− secondary ions exhibited a characteristic enhancement of secondary ion yield due

A methodology for equation-based analysis of large chemical processes using the functional matrix
Korean Journal of Chemical Engineering, 1987The equation-based approach to process analysis is necessary for efficient optimization of large and complex processes, and involves the problem of solving a large number of equations. To complement this approach, an improved equation-solving system using the functional matrix suggested by Mattione, Meir and Book was developed, and its capacity for the
