11. An alternative is to form films with graphite particles adsorbed with hydrogenase inside a polymer matrix . 12. A widely accepted one is the Ogston model which treats the polymer matrix as a sieve. 13. Dispersing the particles throughout the polymer matrix creates a larger interfacial area for charge transfer to occur. 14. Thermoset polymer matrix properties can be fine tuned by the choice of substituents in the bisphenolic compound. 15. Second harmonic generation has been demonstrated as a method to read data written into a poled polymer matrix . 16. Many advanced thermoset polymer matrix systems usually incorporate aramid fibre and carbon fibre in an epoxy resin matrix. 17. As such, recent efforts to toughen CFRPs include modifying the existing epoxy material and finding alternative polymer matrix . 18. The rate of the deblocked leuco dye oxidation is dependent on the pH of the resin polymer matrix . 19. In X-ray systems gadolinium is contained in the phosphor layer, suspended in a polymer matrix at the detector. 20. Protein release occurs mainly by diffusion, which can be regulated by changing the mass within the polymer matrix .
