Performance of Zinc Borate-Treated Oriented Structural Straw Board against Mold Fungi, Decay Fungi and Termites–A Preliminary Trial
2011 - IRG/WP 11-40571
The performance of zinc borate (ZB)-treated oriented structural straw board (OSSB) against mold fungi, decay fungi and termites was examined in standard laboratory evaluations. OSSB was fabricated with split wheat straw and diphenylmethane diisocyante (pMDI) resin. The ZB was added during panel manufacture to achieve preservative levels (wt.%) of 1.0%, 1.5%, 2.0%, and 3.0%. Untreated (0.0% ZB) OSS...

Effect of biodiesel on Performance of Isothiazolone
2013 - IRG/WP 13-30625
Biodiesel has a number of attractive properties, including the ability to readily solubilize a number of biocides and a tendency to reduce odors associated with other solvents such as petroleum-based diesel. Biodiesels, however, have also been implicated in reduced performance of some, but not all preservatives. It is important to assess the effects of biodiesel on each biocide. Soil block tests ...

Properties of plasma etched super black wood
2025 - IRG/WP 25-30825
Super-black materials have very low reflectivity due to structural absorption of light. They are attracting considerable scientific and industrial attention because of their important applications in many fields including astronomy, photovoltaics, and optical science, amongst others. We have developed the first super-black material from wood by etching transverse basswood (Tilia americana L.) surf...

Plasma Modification of Basswood Creates Super-Black Wood
2025 - IRG/WP 25-30826
A super-black wood with low reflectivity in the UV/Vis range is created by plasma modifying transverse basswood surfaces. Here the super-black wood is characterised, the process used to make it is described and its possible practical uses are discussed. Wood samples are exposed to oxygen glow-discharge plasma. Transverse surfaces exposed to high-energy plasma have a deep-black velvety appearance. ...
