Various chemical and physical barrel sanitization methods were evaluated in terms of their effect on oak volatiles in situ. A gas chromatography–mass spectrometry (GC–MS) method using a programmable temperature vaporizing (PTV) injector in solvent-split mode was developed and validated for the...

Forests remain an important resource in Iran, as most of the livelihood activities of local communities, especially in the semi-arid environment of the Zagros forests, are dependent on forest resources. The aim of this study was to identify the type and extent of forest dependency. Semi-structured...

The aim of the paper is to analyze the Romanian forest sector trade balance using the value of main imported and exported wood-based products. Also, an overview of the production, import and export of roundwood, sawnwood, secondary processed and paper industry products is presented. Two types of...

Longitudinal compression induces changes in wood tissue resulting in better bendability. The main purpose of the present study is to identify the changes occurring at the microscopic level. Air-dried oak wood samples (Quercus petraea (Matt.) Liebl.) exposed to a thermo-hydro-mechanical treatment -...

The objective of this paper is to propose a simple and robust additive solution to improve the water-resistance of clay materials by revisiting a traditional recipe of vernacular construction. The influence of the combination of oak tannin with iron chloride on the properties of clay materials in...

Aqueous solutions of iron salts can be applied to a wood surface to modify its color. When applied on wood, iron ions are chelated by the wood's natural phenolic compounds. The resulting color of the wood surface is due to the type of reaction products formed, such as mono-, bis- and tris-...

Wood products that are used in indoor environments can be exposed during their use to UV-vis light through window glass. Exposure of wood products to UV-vis light can cause discoloration due to changes in structures of wood components such as extractives and lignin. In this study, the color...

The paper discusses mechanical properties of timber for structures - most frequently used spruce wood, historically used oak wood and rarely mentioned larch wood. The main focus is on larch wood extracted from the ceiling of an immovable cultural monument from the 17th century - the determination...

For effective applicability of reinforced cork, cork composites reinforced with metal, glass fiber, and carbon fiber were developed, and the effects of the reinforcing materials on the mechanical properties of cork composites were investigated. The bending moduli of elasticity (MOE) of cork...

This study deals with the surface roughness and quality of oak sliced veneers and how these characteristics are influenced by the presence of knots, and other defects associated to knots. The variability of roughness is thoroughly examined along the oak stem, exploring also how it differentiates...
