Nano-scale analysis of copper in wood cell walls treated with amine-copper solution

本研究的目的是检测经胺铜防腐剂处理的管胞细胞壁中铜的纳米分布。采用聚焦离子束(FIB)微细加工技术制作了铜处理木材的超薄切片。切片用最先进的高分辨率透射电子显微镜(HR)和高角度环形暗场扫描电子显微镜(HAADF-STEM)-EDX(能量色散X射线探测器)确定。结果表明，FIB切片结合HR-TEM和HAADF-STEM-EDX是观察木材细胞壁铜纳米分布的有力工具。

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.
