Wood Decay Resistance Employing Nanoparticle Protective Systems
International Journal of Conservation Science, 2023 In this paper, nanoparticle dispersions (nanosilver, copper nano oxide, nanozinc, and nanosilica) have been formulated to be used as protective impregnants. Since all the components of the formulations could be charged according to the pH of the medium, the solutions were formulated with the two profiles of pH=3 and pH=8 (pH changes were handled with ...

Decay-resistance of particleboard.
Wood Preservation, 1986 微小菌類を含む種々の菌類に対して,市販されているパーティクルボードの耐朽性を評価すべく実験を行った。また,ボードの曲げ強度に及ぼす菌類の影響も調べた。ボードの重量減少率は,菌の種類によって変動した。かっ色腐れ菌オオウズラタケは,メラミンユリア樹脂製ボードに大きな重量減少率を生じたが,フェノール樹脂製ボードを腐朽しなかった。一方,白腐れ菌カワラタケは場合によって,メラミンユリアボードよりもフェノールボードに,より大きな重量減少率を生じた。JWPA規格3号で評価した場合,一般にボードの耐朽性は高かった。ボードの曲げ強度は,腐朽の進行とともに急激に減少した。同一重量減少率では,メラミンユリアボードとフェノールボードの強度減少間に,差を認めることは出来ない ...

Decay Resistance of Weathered Beech Wood
Journal of Anatolian Environmental and Animal Sciences, 2020 Wood is susceptible to photo-degradation in outdoor applications, and deformations occur on its surface such as micro or macro cracks, color changes etc. Especially, cracks make wood material more vulnerable to biotic attacks. In this study, decay resistance of natural and accelerated weathered beech samples was investigated by a brown (Coniophora ...

Magnetoplasmon resonance in 2D electron system driven into a zero-resistance state [PDF]
, 2012 We report on a remarkably strong, and a rather sharp, photoresistance peak originating from a dimensional magnetoplasmon resonance (MPR) in a high mobility GaAs/AlGaAs quantum well driven by microwave radiation into a zero-resistance state (ZRS).

Unsteady effects during resistance tests on a ship model in a towing tank [PDF]
, 2008 It is known that there are oscillations in the wave resistance during the constantvelocity phase of a towing-tank resistance test on a ship model. In this work, the unsteady thin-ship resistance theory has been applied to this case. The results have been
