Extraction and characterization of nanocellulose from waste of date palm "Phoenix dactylifera″ as reinforcement of polymer composites.

The cellulose is the most abundant and renewable polymer in nature. It is characterized by its biodegradability that can help to establish a friendly environment. The main objective of this study is intended to characterize the nanocellulose obtained from waste date palm,  including the dried palms (DP) and the fresh palms (FP) by implementing chemical methods (hydrolysis with H2SO4).

Insights into the Characterization of the Self-Assembly of Different Types of Amphiphilic Molecules Using Dynamic Light Scattering.

The self-assembly of cetyltrimethylammonium bromide, sodium dodecylsulfate, Triton X-100, and sulfobetaine surfactants in aqueous solutions was examined by dynamic light scattering, both in the presence and absence of 0.1 M NaCl salt, across various temperatures. For each surfactant, critical parameters, such as concentration and phase transition temperatures, of micelles were determined by monitoring changes in the hydrodynamic diameter with concentration and temperature.
