High surface selectivity of atmospheric pressure plasma treatment was demonstrated experimentally by XPS depth profile measurement of plasma-activated beech wood. Wood surface activated by diffuse coplanar surface barrier discharge was sequentially sputtered by Ar+ ion beam followed by immediate XPS analysis of freshly uncovered surface. According to the(More)
In the furniture and construction industries, there is increased demand for lightweight, high-performance, and low-maintenance materials with specific properties. Increased demand necessitates testing of new and composite materials to find a viable alternatives to classical materials. In this study, two different types of cork layered plywood composites(More)
Countries described as ‘fragile states’ need timely sustained assistance to help rebuild basic infrastructure and institutions. However, with available funds becoming limited and number of ‘fragile states’ increasing, competition for such assistances have also become intense. To select countries for the fragile states support facility, a number of(More)
A new sandwich composite structure was prepared that utilizes classic wood-based composites as the core and face materials. Particleboards were used as faces, which covered a plywood-made iso-grid core. A new type of core-face fixation was suggested and assessed. The sandwich panels can be regarded as lightweight, as their density was below 400 kg/m.(More)
The investigation of the hydrothermal exposure effect on the glue-line strength is obvious when outdoor application of wood products is in option. In our research the bonding quality of oak (Quercus L.) and beech (Fagus sylvatica L.) wood was tested in different conditions according to EN 205. After each exposure the lap joint test specified the shear(More)
The utilization of Social media tools in business enterprises has tremendously increased with an increased number of users and a corresponding upsurge in time spent online. Online social media services such as Facebook and Twitter are used by companies to introduce new products and services, provide various supports and interact with customers on daily(More)
This research is on a new development towards three-dimensional surfaces for wood-based panels, i.e., particleboards (PB). By imprinting a self-designed stainless steel grid on both sides of PB the following research questions were investigated: (1) feasability of the 3D-pattern imprintment during hotpressing of resinated PB furnishes, (2) assessment of(More)
