Eglinton et al. [688] described a practical approach for isolation of individual compounds from complex organic matrices for natural abundance radiocarbon measurement. This approach uses an automated preparative capillary gas chromatography (PCGC) to separate and recover sufficient quantities of... 

The consumption of composites with organic matrices is a few percent of the total plastic consumption. 

Among soft organic matrices for electrochemical applications, polysulfone (PSf) appears as a suitable and not very exploited candidate with very attractive properties including a remarkable stability at high temperatures and extreme pH conditions [112].

Spectroscopic studies of DPCs (14a) have been most extensively done in an Ar matrix as well as in organic matrices. The wealth of the data may be due to the fact that a precursor, diphenyldiazomethane, is available that can be prepared and handled in a relatively simple way. Most of DPCs are stable in an organic matrix at liquid nitrogen temperature. 

The technique of noncovalent derivatization employs the noncovalent intermolecular forces (hydrogen bonding, 7t-stacking, UpophUic-lipophilic interactions, and electrostatic interactions) to trap the molecular species in organized matrices.

Kieffer et al., in 1971, observed a temperature-independent luminescence caused by the recombination of electron and hole centres in irradiated vitreous organic matrices [6], The authors suggested that the recombination proceeds via electron tunneling. 

In 1972, Miller made a detailed analysis of the data on the influence of electron acceptor additives on the yield of ionic products during radiolysis of organic matrices and showed this to agree quantitatively with the electron tunneling mechanism of the formation and annihilation of these particles [7], In particular, the annihilation of et) in MTHF glass containing naphthalene (Nh) as the additive was found to be accompanied by simultaneous formation of the Nh anion radical (via the reaction etj. + Nh - Nh ). The kinetic curves for this reaction at 77 and 87 K coincided, which ruled out the possibility of the reaction rate being determined by thermal diffusion.
