Evaluation of vessel features on physical and mechanical properties of wood of Common black poplar (Populus nigra L.) grown at different elevations in the region with a continental climate
2014 - IRG/WP 14-40656
This study essentially examined the effect of elevation on the anatomical structure, and the physical and mechanical properties of Common black poplar (Populus nigra L.) wood. The scope of the study was to observe the variability of vessel element features on physical and mechanical properties of Common black poplar (Populus nigra L.) in relation to habitat at different elevations. For this purpos...

The durability of natural and thermomodified black poplar wood and Scots pine sapwood after two years of external exposition
2016 - IRG/WP 16-40730
Natural biological durability of many European wood species is considered to be relatively small, particularly in a ground contact conditions. This is due to the exposure of the wood to the range of biological and atmospheric destructive factors. This may to limit the scope of application of the wood of these species, particularly in construction. The biocides are often used for wood protection in...

Colorant Treatments to Enhance the Weathering Resistance of Western Red cedar
2016 - IRG/WP 16-40737
Western redcedar is renowned for its decay resistance, but, like most wood products, it requires frequent maintenance in many exterior applications to maintain its appearance. To provide adequate long-term performance in exterior applications, it must be protected against light, water, and disfiguring fungal growth. Colorant treatments, with and without preservatives, were investigated for their a...

Black-stain Resistant Acrylic Latexes for Wood Coatings Applications
2017 - IRG/WP 17-40786
Translucent coatings on wood in exterior applications often fail due to photodegradation and colonization by black-stain fungi and require frequent refinishing. This limits competitiveness with alternative materials. In this project, it was hypothesized that an effective dispersion of inorganic nanoparticles will provide a translucent coating with long-term resistance to black-stain fungi. Functio...

Bio-preservative properties of technical lignins from South African pulp mills: An investigation towards a conceptualized development of natural compound-based wood preservatives
2018 - IRG/WP 18-30724
The depletion of naturally durable timber and the risk posed by some of the conventional wood preservatives to human health and the environment continue to drive research efforts towards developing new formulations that are benign. Furthermore, the global concept of environmental sustainability aims at optimal use of resources and to comprehensively include conversion of waste to value added produ...

Fungicidal properties of black liquor from the waste MDF board digestion in terms of wood protection
2023 - IRG/WP 23-50379
The aim of the work was to determine the fungicidal properties of black liquor as a product of the chemical digestion of waste MDF board. The resistance of wood treated with black liquor from MDF waste pulping process was compared with the resistance of wood treated with black liquor from the pulping process of a by-product from agricultural production. The control material consisted of non-treate...

The durability and mechanical properties of 40 years old Black locust poles
2024 - IRG/WP 24-11042
This study investigates the durability and mechanical properties of 40-year-old black locust (Robinia pseudoacacia) poles harvested from a vineyard in Slovenia. Wood from these poles was compared to recently harvested black locust wood to determine possible reuse options. Visual inspection, hyperspectral imaging, and laboratory tests were conducted to assess decay, density, mechanical properties, ...

Microbial symbionts in the shipworm gut: a new finding resolving a century old mystery explaining how shipworms digest lignin
2025 - IRG/WP 25-11061
Shipworms, historically known for their destruction of wooden ships and coastal structures, also play a key role in carbon and nutrient cycling in aquatic ecosystems. Despite extensive research, the exact mechanisms underlying their ability to digest wood, and particularly how they digest lignin, have remained elusive. A better understanding of the way that they attack and digest wood will potenti...
