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, ...
Microwave-assisted synthesis of some hybrid molecules derived from morpholine and investigation of their antimicrobial activities
(Wiley-VCH Verlag GmbH, 2017)
2H-1,2,4-triazol-3(4H)-one compound was obtained starting from 4-(2-fluoro-4-nitrophenyl)morpholine via several steps. Then, these compounds were converted to the corresponding fluoroquinolone hybrids via one pot three ...
Accelerated weathering performance of Scots pine preimpregnated with copper-based chemicals before varnish coating Part:1 coated with cellulosic and polyurethane varnishes
(Wiley, 2020)
This study aimed to determine the effect of accelerated weathering on gloss, surface
hardness and colour changes of Scots pine (Pinus sylvestris L.). Test samples were
impregnated with Adolit KD‐5, Wolmanit CX‐8 and ...
Antimicrobial, antioxidant and antiproliferative activities of novel quinolones
(Wiley-VCH GmbH, 2020)
The compound (2) formed by esterification of dimethyl morpholine (1) was converted to acetohydrazide (3). Subsequently Schiff bases (4 a-d) and carboxy(thio)amide derivatives (5 a-e) were synthesized. Then 1,2,4-triazole ...
Bacterial cellulose as reinforcement in paper made from recycled office waste pulp
(North Carolina State Univ Dept Wood & Paper Sci, 2020)
Bacterial cellulose, produced during fermentation of Kombucha tea, was investigated relative to its ability to modify the characteristics of pulp from recycled office wastepaper. The produced bacterial cellulose wet films ...
