Preparation and Properties of Nanocellulose from Organosolv Straw Pulp
The object of this work is to present a study of nanocellulose preparation from organosolv straw pulp (OSP) and its properties. OSP was obtained through thermal treatment in the system of isobutyl alcohol-H2O-KOH-hydrazine followed by processing in the mixture of acetic acid and hydrogen peroxide for bleaching and removal of residual non-cellulosic components. We have obtained nanocellulose fro...
متن کاملPresence of Hardwood Chips and Its Impact on Pulp Strength Properties in the Production of Bleached Softwood Kraft Pulp
The effect of hardwood admixture (15-25% birch or aspen) in kraft cooking on the strength properties of the fully bleached pulp was investigated. Results obtained from both laband mill-processed ECF bleached pulps showed that adding 15-25% birch or aspen to the production of fully bleached softwood kraft pulp had a minor effect on the strength properties. No significant effect was observed for ...
متن کاملSubstitution of High-yield-pulp for Hardwood Bleached Kraft Pulp in Paper Production and Its Effect on Alkenyl Succinic Anhydride Sizing
In recent years there has been an increasing interest in using high-yield pulp (HYP) as a partial replacement for hardwood bleached kraft pulp (HWBKP) in the production of high-quality fine papers as a cost-effective way of improving the product performance. This study investigated the substitution of HYP for HWBKP and its effect on the Alkenyl Succinic Anhydride (ASA) sizing performance. The r...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Electrochemically mediated seawater desalination.
With global demand rising faster than availability, fresh water is quickly becoming a limited resource. In fact, the United Nations estimates one third of the world s population is living in water-stressed regions, and by 2025 this number is expected to double. Seawater desalination is an attractive solution to this problem because seawater accounts for more than 97% of the world s water supply...
