Surface characteristics of heated and varnished oriental beech after accelerated weathering
(Slovak Forest Products Research Inst, 2017)
This study was performed to investigate some surface characteristics such as surface hardness, surface roughness, and color changes of heated and varnished Oriental beech (Fagus orientalis Lipsky) after accelerated weathering. ...
Synthesis and antimicrobial activities of hybrid heterocyclic molecules based on 1-(4-fluorophenyl) piperazine skeleton
(Bentham Science Publishers, 2017)
Background: The amine (2) was prepared starting from 1-(4-fluorophenyl) piperazine via two steps, and then converted to the corresponding hydrazide (4). The reaction of hydrazide (4) with carbon disulfide generated the ...
Synthesis and antimicrobial activity of new piperazine-based heterocyclic compounds
(Walter De Gruyter Gmbh, 2017)
The hydrazide 5, that was obtained from -1-(4-fluorophenyl) piperazine (1), was converted to the cor-responding carbothioamides 6a-c by the reaction with alkyl(aryl) isothiocyanates. The synthesis of conazole analogs 10a-f ...
Weathering properties of scots pine treated with some chemicals
(Slovak Forest Products Research Inst, 2017)
This study was aimed to investigate the gloss, surface hardness, surface roughness, and color changes of Scots pine that was treated with some chemicals after six months of weathering exposure. Chromated copper boron (CCB), ...
Comparison of reinforced oxygen delignification methods for old corrugated board (OCC) fibres
(Inst Technol Drewna, 2017)
The present work focuses on the effects of sodium percarbonate and hydrogen peroxide as reinforcing agents for the oxygen delignification of old corrugated container paper (OCC). The chemical and crystalline structure, ...
Effect of press temperature on some properties of cement bonded particleboard
(Universidade Federal de Sao Carlos, 2020)
It is known that there is a correlation between hydration heat and physico-mechanical properties of wood based cement panels. Cement hydration is affected by many variables, such as chemical composition, water/cement ratio, ...
