The effect of adding nanosized fillers (nanoparticles of Fe, FeO 褏 , Al, and Al 2 O 3 ) on curing of filled polymer epoxy composites based on ED-20 was studied. The thermal effect of curing is independent of the presence of filler nanoparticles in the composites. On the other hand, ...

mainly concerning its chemical composition and pharmacological activity [1,5–9]. In this review, we strictly analyze the current state of knowledge of phytochemistry, quality control, pharmacological effects, and pharmacokinetics. It is hoped that this review will fill the knowledge gap, complement ...
When the number of monomers is very large, the compound is sometimes called a high polymer. Polymers are not restricted to monomers of the same chemical composition or molecular weight and structure. Some natural polymers are composed of one kind of monomer. Most natural and synthetic polymers, ...
In general, MNBs are negatively charged at various pH conditions as indicated by their zeta potential However, the surface charge of MNBs can be modified by the surrounding environment's composition, providing the opportunity for fine-tuning their properties for optimal performance in different ...
