Summary
The necessity for renewable resources-based polymers, nanomaterials and nanocomposites with high performance is inevitable and increasing steadily over the last three decades or so due to ever increasing world population and comfort in human life in one hand, and depletion of fossil fuel reserves, global warming and environmental rules and regulations on other hand. Thus the scientists and researchers have tried to exploit the naturally renewable resources as the feed stocks for the development of their desired products. In the current state-of-art, bio-based such products are growing tremendously because of their promising and advantageous attributes over their conventional non-renewable resource-based analogs. So, the editor intended for the original research and review articles in the field of polymers and nanomaterials as well as their combinations, obtained from renewable resources, in this special issue.

Abstract There is an increasing interest in developing nanoparticles with diverse
biologic activities. To this end, we prepared 10 to 15 nm silver nanoparticles
(AgNP) from native isolates of
Trichoderma atroviride. Within this study, endophytic fungi hosted four medicinal plants in Saint Katherine Protectorate, South Sinai,
Egypt have been isolated by surface sterilization technique on four isolation media.
Ten species, based on their frequency of occurrence, out of twenty recovered taxa
were tested for their capability to synthesize extracellular AgNPs.
Trichoderma
atroviride hosted
Chiliadenus montanus was found to be the best candidate for
the production of mycogenic AgNPs among all examined…

Orientation on the Mechanistics of Electron-Transfer on Oxidation of Chondroitin-4-Sulfate as Sustainable Sulfated Polysaccharide by Permanganate Ion in Aqueous Perchlorate Solutions
Refat Hassan, Hideo Takagi, Samia Ibrahim
Journal of Renewable Materials, Vol.8, No.2, pp. 205-218, 2020, DOI:10.32604/jrm.2020.08530

Abstract A spectrophotometric investigation of oxidation of chondroitin-4-sulfate
(CS) as a sustainable and biodegradable sulfated macromolecule by oxyanion permanganate ion as multi-equivalent oxidant in acid perchlorate solutions at a constant
ionic strength of 2.0 mol dm
-3 has been studied. The experimental results on the
influence of the concentration of the reactants the reaction rates revealed first-order
dependence in MnO
4–
, fractional second-order in [CS] and fractional first-order with
respect to the hydrogen ion concentration. The hydrogen acid concentration dependence of the rate constants indicated that the oxidation rates were increased with
increasing the acid concentration which means that the oxidation reaction…
