Selvedge concept

The Selvedge concept introduced by the Rabalais team (Honda et al. 1978 Lancaster etal. 1979 Murray 1981)... 

Selvedge concept A model describing molecular secondary ion emission Segregation De-mixing of atoms within a solid as a result of chemical forces Semi-empirical Calculations in which known parameters, i.e. stracture, are input... 

Karas, Bahr, and Stahl-Zeng emphasized the multiple functions of the matrix in 1996, especially proton transfer reactions of the matrix with analyte. A focused review of MALDl ionization mechanisms appeared in 1998, " which also expUcitly introduced the concept of distinct primary and secondary ion formation processes. The former are rapid, early events creating the first ions. Initial ions may later undergo secondary reactions in the expanding plume, in a manner similar to the SIMS selvedge concept. ...
