Use of X-Ray Micro-Computed Tomography to Visualize Copper in Preservative Treated Wood
2012 - IRG/WP 12-20488
This study tests the hypothesis that X-ray micro-computed tomography will be able to visualize the distribution of copper in wood treated with a micronized wood preservative containing copper carbonate. A small wood block measuring 12 x 12 x 19 mm was cut from a 2.4 m x 51 mm x 51 mm southern pine batten that had been treated with a micronized wood preservative. Tomograms of the wood block were ob...

Visualization of Copper in the Voids and Cell Walls of Treated Wood using X-Ray Micro-Computed Tomography
2013 - IRG/WP 13-40640
This study extends our observations of the distribution of copper in treated wood. A small wood block was cut from a southern pine batten that had been treated with a particulate-copper preservative and similar sized block was cut from a batten that had been treated with a copper-amine preservative. Both blocks were imaged using X-ray micro-computed tomography. We obtained tomograms of each treate...

Accumulation of copper in parenchyma cells in southern pine wood treated with micronized and amine-copper preservatives
2019 - IRG/WP 19-20657
Our previous research used X-ray micro-computed tomography to examine the micro-distribution of copper in southern pine wood treated with a micronized wood preservative (MCA) and an amine-copper preservative (ACQ). We found that copper in wood treated with MCA was mainly concentrated in fusiform rays (rays containing resin canals), and in vertical (axial) resin canals. A similar, although not iden...
