Different polymer architectures behave differently regarding their dynamics. We have used a combination of dielectric spectroscopy, and fast field cycling nuclear magnetic resonance (NMR) to compare the dynamical behavior two different architectures, with similar overall molecular weight. The systems interest are bottlebrush linear one, both based on poly(dimethylsiloxane) (PDMS). To verify str...

The chemical composition and the antibacterial activity of the essential oils obtained by hydrodistillation from the leaves of Callistemon citrinus and Callistemon viminalis were analyzed by GC and GC/MS. Twenty-four and twelve components were identified for C. citrinus and C. viminalis, representing 92.0% and 98.3% of the total oils. The major components of C. citrinus and C. viminalis were 1,...

Architecturally different polymer chains lead to fundamentally rheological responses and internal dynamics, which can be utilized rationalize advanced thermoplastic nanocomposites with tunable mechanical behavior. In this work, three model poly (methyl methacrylate) (PMMA) polymers linear, bottlebrush, star architectures the same total molar mass were investigated in their neat form, well-dispe...
