Time-resolved laser spectroscopy for the in situ characterization of methacrylate monomer flow within spruce

摘要: Time-resolved diffuse optical spectroscopy (TRS) was investigated as a nondestructive method to characterize the post-impregnation distribution of methacrylate monomers within spruce (Picea abies). TRS also used monitor flow in situ, spruce, during impregnation with both spatial and temporal resolution. The data were compared fluid models developed by Darcy Bramhall demonstrating that neither these able accurately describe experimental results, highlighting need for development new models. Nondestructive characterization did not require staining monomer treatment solution, multivariate analysis or complex sample pre-treatment, thus facile applicability this technique.
