Treatability of native and exotic alternative timber species
2019 - IRG/WP 19-40864
The service life of moderately durable species can be extended significantly if the challenge of effective treatment of refractory wood species can be overcome. Along with preservative effectiveness, the performance of preservative in treated wood depends on factors such as retention and penetration in treated wood, the wood anatomy, the uniformity of penetration and micro-distribution within the ...

Virtual Reality of Wood Protection
2023 - IRG/WP 23-20698
Virtual reality (VR) is a technology that allows people to explore and interact with computer generated environments using devices that stimulate different senses (sight, sound and touch). VR is mainly used for education, training and entertainment, but it also has the potential to provide new insights into scientific phenomena. In this paper we describe the evolution of VR and its many uses, focu...

Towards a microactuator-sensing network for the structural health monitoring of wood
2023 - IRG/WP 23-50380
Timber structures decay over time with degradation in their structural integrity. Changing environmental conditions, varying loads, exposure to moisture or insect attacks lead to changes in their vibrational response behaviour. Here we present a low-cost device used as a triggered exciter to enable the monitoring of the structural integrity of timber bearers or even power poles in electricity netw...

Do naturally sequestered biocidal metals contribute to the marine borer resistance of turpentine?
2024 - IRG/WP 24-11036
Turpentine wood is renowned for its resistance to attack by molluscan marine borers. This resistance is thought to be due to its high silica content, and possibly the presence of other, as yet unknown, compounds. Silica in turpentine wood is present as particles in rays, but in many plant species silica also occurs in cell walls. We hypothesized that Si is present in cell walls of turpentine, but ...

X-ray micro-computed tomography of copper distribution in CA, ACQ and MCA treated wood and changes in microstructure of ACQ-treated southern pine following natural weathering
2024 - IRG/WP 24-20707
We hypothesized that X-ray micro-CT would be able to visualize: (a) the distribution of copper in CA-treated southern pine; and (b) microstructural changes in ACQ-treated southern pine exposed to natural weathering. Small blocks were removed from southern pine samples treated with CA and also southern pine treated with ACQ and MCA. Small blocks were also removed from ACQ-treated boards (flat and p...

Virtual reality of wood protection
2024 - IRG/WP 24-20727
Virtual reality (VR) is a technology that allows people to explore and interact with computer generated environments using devices that stimulate different senses (sight, sound and touch). VR is mainly used for education, training and entertainment, but it also has the potential to provide new insights into scientific phenomena. We describe our work on the use of VR as a learning tool for students...
