Evaluating the Process of ACQ-Treated Woods with TGAand CEM Analysis
2007 - IRG/WP 07-20374
To provide an understanding of the fundamental thermal behaviour and the disposal-end products of ACQ-treated woods, this study is comprised of two categories of examination. The first is related to the use of TGA under different thermal decomposition conditions (nitrogen or air, and 5 or 40 oC/min), and the use of EDX to examine certain residual elements of the char. The second applies the CEM ...

Laser stain removal of fungus-induced stains on paper-based cultural relics
2007 - IRG/WP 07-40389
Laser techniques has been developed and applied in commercial use for 40 years, but it has not been used successfully to remove stains from paper-based cultural relics . The purpose of this study was to investigate the paper cleaning by using a technique of Nd-YAG laser. Artificial stained papers were inoculated with fungi and then were treated at different laser cleaning parameters, in order to f...
