| Outline of Final Research Achievements |
The purpose of this study is to examine the atomic-level imaging of copper in cell walls of tracheid treated with amine copper preservative. FIB (Focused Ion Beam) micro processing and manual sectioning by hand using a box-knife were used to make ultra-thin sections from amine copper treated woods for electron microscopy. The sections were determined by spherical aberration-corrected HAADF-STEM (High-Angle Annular Dark-Field-Scanning Transmission Electron Microscope)-EDX (Energy Dispersive X-ray detector). The results show that manual sectioning in combination with HAADF-STEM-EDX is a powerful tool for observing the atomic-level imaging of copper in wood cell walls.
