Water repelling Populus Alba by emulsion of paraffin, Quaternary ammonium and hydrated starch
Volume 25, Issue 2 , September 2018, , Pages 211-222
Abstract
The water repellency and dimensional stabilization of wood species are important for outdoor uses. In this study, the water absorption and water repelling of poplar wood (Populus Alba) by emulsion of paraffin, Quaternary ammonium and starch, were investigated. Paraffin in three levels of 0%, 3%, 5%, ... Read MoreInvestigation on the influence of nutrients and treatment period on enzyme activities of Phanerochaete chrysosporium
Volume 25, Issue 2 , September 2018, , Pages 275-290
Abstract
In the course of enhanced bioremediation, addition of nutrients such as carbon, nitrogen, phosphorous, etc, substrates, electron acceptors as well as vitamins (Thiamin, etc) and veratryl alcohol, increased metabolic activities, will influence the production of enzymes and enhances the deterioration of ...

Volume 27, Issue 2 , June 2012, , Pages 256-266
Abstract
Soda - oxygen pulping of old corrugated container to produce totally chlorine free bleached pulp was investigated. In order to reach the optimum delignification condition; four levels of sodium hydroxide (9, 11, 13, and 15 %), three cooking times (90, 120, and 150 minutes) and two cooking temperatures ...

Volume 26, Issue 1 , March 2011, , Pages 10-25
Abstract
In this study, changes in optical behavior of poplar Kraft lignin and bagasse Soda lignin, before and after reducing with sodium borohydride and sodium hydrosulfite (dithionite) and also after methylation using dimethyl sulfate, was monitored by measuring optical indices (brightness, k/s, whiteness and ...
