| Research Abstract |
The purpose of this study is to examine the nanodistribution of copper in cell walls of tracheid treated with amine copper preservative. FIB (Focused Ion Beam) micro processing was used to make ultra-thin sections amine copper treated woods for electron microscopy. The sections were determined by state-of-the-art HR (High Resolution)-TEM (Transmission Electron Microscope) and HAADF-STEM (High-Angle Annular Dark-Field - Scanning Transmission Electron Microscope) - EDX (Energy Dispersive X-ray detector). The results show that FIB sectioning in combination with HR-TEM and HAADF-STEM-EDX is a powerful tool for observing the nanodistribution of copper in wood cell walls.
