Introduction of sulfonated bamboo (bamboo-SO3H) as a new catalyst for the facile synthesis of bis(indolyl)methanes
Bamboo is one of the important biopolymers which is used in chemistry. In this work, for the first time, a solid acid catalyst from bamboo was prepared from the reaction of sawdust bamboo and chlorosulfonic acid. Relevant properties of catalyst were investigated by FT-IR, XRD, SEM and TGA. The sulfonated bamboo (bamboo-SO3H) with several acid functional groups was utilized as highly ...
متن کاملTensile Strength Analysis of bamboo and Layered Laminate Bamboo composites
Tensile properties of bamboo laminae, prepared from bamboo slivers, selected from different regions of bamboo culms (Dendrocalamus strictus), increases from inner to outer region for any cross section and the same is experienced from bottom to top. Application of rule of mixture, on linear regression line drawn from test results, show that fiber strength increases and matrix strength decreases ...
متن کاملEffect of Bamboo Flour Grafted Lactide on the Interfacial Compatibility of Polylactic Acid/Bamboo Flour Composites
Bamboo flour (BF) was grafted onto lactide (LA) in the molten state using stannous octoate as a catalyst to form BF-g-LA. Then, polylactic acid (PLA) was blended with BF (PLA/BF, 85/15 wt %) to prepare PLA/BF/BF-g-LA composites using BF-g-LA as a compatibilizer. The grafting rate of BF was characterized using infrared testing and elemental analysis. To investigate the effect of BF-g-LA on the p...
متن کاملUnderstanding the Structural Properties of Moso Bamboo to Engineer Sustainable Structural Bamboo Products
This document presents the study of unprocessed Moso bamboo’s structure and mechanical properties, and the relation of two through modeling. Mechanical test results are presented, as well as models developed from micrographs.
متن کاملOn the multi _ chi-square tests and their data complexity
Chi-square tests are generally used for distinguishing purposes; however when they are combined to simultaneously test several independent variables, extra notation is required. In this study, the chi-square statistics in some previous works is revealed to be computed half of its real value. Therefore, the notion of Multi _ Chi-square tests is formulated to avoid possible future confusions. In ...
