Volume 37, Issue 1 , April 2022, , Pages 17-27

https://doi.org/10.22092/ijwpr.2021.353685.1666

Abstract
  In this research, the effect of  using nano-zinc oxide (nano-ZnO) as a UV absorbent on the weathering resistance of wood- polypropylene composite was investigated. For this purpose, composite samples containing 0, 1, 2 and 3% nano-ZnO were manufactured using an internal mixer and a laboratory press. ...  Read More

Volume 30, SPRING 1 , May 2015, , Pages 1-13

https://doi.org/10.22092/ijwpr.2015.10780

Abstract
  In the present study, preparation of cotton stalk (Sahel variety) as one of the common agricultural residues was studied through three stages as Soda-AQ chemical pulping, delignification and alkaline treatment, aiming for the production of cellulose nanocrystal. In order to identify the optimum condition ...  Read More
