Article
Identification of wood species with fast, reliable and non-destructive methods is highly important for forestry and wood-related industries. Near-infrared spectra of anatomically similar pine species (Pinus sylvestris L. and Pinus nigra J.F. Arnold) were taken and analysed by partial least squared discriminant analysis (PLS-DA) for comparing the ef...

Impact of heat treatment (ThermoWood) on the macro structure and physical properties of Scots pine sapwood and heartwood were studied by visual examinations, using the following relevant standard test methods: ASTM D2244 and TS 2472, respectively. In the study, two processes-Thermo-S (190 ̊ C) and Thermo-D (212 ̊ C)-were employed for heat treatment...

This study evaluates the microscopic changes of paulownia solid wood panels subjected to thermal compression via characterizing the changes in wood microstructure. The panels, with dimensions of 500 mm × 100 mm × 20 mm, were hot-pressed in a tangential direction by using a laboratory-type hot press at a temperature of either 150 °C or 170 °C and a...

This study identified the wood species and evaluated the degree of weathering and biological degradation of a historical timber construction element originating from the Great Metéoron monastery in Metéora, Greece. The wood material was provided from the interior side of a balcony that was fully covered with a roof and exposed to outdoor conditions...

The combined effects of temperature and compression on the microstructure of solid-wood panels produced by Aspen (Populus tremula) wood were evaluated. Thermal compression was applied on aspen wood to increase the density for improving its physical and mechanical properties. The solid wood panels with dimensions of 100 mm by 500 mm by 25 mm were ho...
Article
Comparative wood anatomy is the most accepted (traditional) method for wood identification. However, there is an ongoing search for an effective method where traditional methods may be insufficient in distinguishing on the species level. Near-infrared spectroscopy (NIRS) is one of the developing methods for wood identification. Near-infrared data o...

Abstract :This paper aimed to identify the wood species and evaluate the structure of old wooden window-frames taken from Istanbul University, Forestry Faculty, Oksal Building. Macroscopic and microscopic examinations were performed to determine the wood species and evaluate the structural alteration of wooden materials. The macro-structure of wood...

The combined effects of press temperature and pressure on the anatomical structure of solid-wood panels produced by European poplar (Populus tremula L.) wood were evaluated. The solid wood panels with dimensions of 100mm by 500mm by 25mm were hot-pressed by using a laboratory hot press at a temperature of either 150°C or 170°C and pressure of eithe...

Species-based discrimination for some wood species which cannot be clearly distinguished by microscopic methods. The classification power of NIRS will be examine from genus to species in order to see the operability of the system from easy to difficult, and this analysis will be demonstrated with oak and pine species (Quercus petraea (Mattuschka) Liebl., Quercus frainetto Ten., Pinus sylvestris L., Pinus nigra J.F. Arnold). A data bank will be created to be used in the NIRS method for fast and effective identification of these species.
