This work reports the dielectric behavior of biopolymer ethyl cellulose (EC) observed from transient currents experiments under action a direct current (DC) electric field (~107 V/m) vacuum conditions. The viscoelastic response EC was evaluated using dynamic mechanical analysis (DMA), observing relaxation related to glass transition around ~402 K. Furthermore, we propose mathematical framework that describes in fractional differential equation, whose solution involves Mittag–Leffler...
In this work, the viscoelastic behavior of high-density polyethylene (HDPE) and polypropylene (PP) was studied through stress relaxation experiments conducted at different strain levels. The main objective to evaluate classical, fractional, conformable derivatives analyze molecular mobility, using statistical methods identify most accurate representation response. Besides coefficient determination (R2), average absolute deviation (AAD) mean squared error (MSE) were used as evaluation...
Abstract A magnetic hybrid material (MHM), consisting of iron‐oxide nanoparticles (˜4 nm) embedded in sodium carboxymethyl cellulose (Na‐CMC) matrix was synthesized. The MHM synthesis process performed two stages. First, a precursor (Fe(II)‐CMC) synthesized from aqueous solutions: Na‐CMC solution and FeCl 2 solution. In the second stage, treated with H O under alkaline conditions to obtain MHM. results obtained X‐ray diffraction show that crystalline structure iron oxide into corresponds...
Today, shape memory alloys (SMAs) have important applications in several fields of science and engineering. This work reports the thermomechanical behavior NiTi SMA coil springs. The characterization is approached starting from mechanical loading-unloading tests under different electric current intensities, 0 to 2.5 A. In addition, material studied using dynamic analysis (DMA), which used evaluate complex elastic modulus E* = E' - iE″, obtaining a viscoelastic response isochronal conditions....
In this work, iron oxide nanoparticles (~5 nm) embedded in a chitosan polymer film, were synthesized. order to obtain nanostructured material, firstly homogenous film of Fe(II)-chitosan was prepared. The resulting composite has thickness ~140μm. Iron in-situ synthesized by treating the with H2O2 under alkaline conditions. morphological analysis Transmission Electron Microscopy (TEM) shows and stabilized film. magnetic behavior studied magnetization measurements. curves at room temperature...
