Health matrix—toxic waste isolation
American Industrial Hygiene Association Journal, 1982United States Industry is undertaking projects which require the cleanup or physical isolation of toxic materials. Chlorinated hydrocarbons are one of the most persistent chemicals which must be segregated from the environment. This paper describes the matrix implemented to protect the community and workers during decontamination activities of chemical

Matrix Isolation of Chalcogeno Heterocumulenes
Sulfur reports, 1999Abstract The application of matrix isolation techniques connected with quantum mechanical calculations on generation and structural elucidation of cumulenic compounds containing sulfur or oxygen has been reviewed. Experimental matrix IR and UV/VIS data for all known species of this class of substances have been summarized together with some matrix ...

Abstract Matrix isolation is a technique for trapping reactive species at very low temperatures and studying them spectroscopically. This book offers detailed practical advice on how to carry out matrix-isolation experiments, and is a unique introduction to the subject. Chapter 1 introduces a brief historical survey of the development of

Matrix for isolation of technetium and actinides
Doklady Chemistry, 2010Radioactive waste of nuclear power engineering is a considerable environmental hazard. Liquid highly radioactive waste (HRW) of irradiated nuclear fuel reprocessing is most hazardous. Such HRW with com plex chemical composition is solidified into glassy confinement matrices to improve its storage safety [1].

Matrix isolation by solid helium
Physica B: Condensed Matter, 2003Abstract We have developed a new technique for embedding micro-impurities into solid helium. It is based on sedimentation of a jet of helium mixed with impurities on a gas–liquid and then liquid–solid interface, the He solid is continuously moved downwards by removing helium gas from the bottom of the cell.

Matrix isolated clusters and microcrystals
International Journal of Quantum Chemistry, 1981AbstractAfter emphasizing the importance of absorption spectra of metal clusters, with special reference to alkali halide IR absorption, the equilibrium configurations and the binding energies of alkali halide clusters are discussed in terms of a very simple two‐body interaction.

Spectroscopy of matrix-isolated methylnitrene
The Journal of Chemical Physics, 1987The methylnitrene radical CH3N has been produced by the interaction of metastable molecular nitrogen and methylazide, and has been trapped in solid nitrogen at 10 K. The IR and UV absorption spectra are consistent with gas phase emission results, and also show transitions to several additional vibrational levels in the A 3E excited electronic state ...
