... defined XRD pattern was observed corresponding to Fe 3 O 4 NPs with cubic structure. The intensity of the diffraction peak of (311) plane of both samples is stronger than the other peaks. The intensity of peaks of Fe 3 O 4 @KNM NPs is stronger than intensity of Fe 3 O 4 @CFX NPs. The average crystal size...

...Peter Torab; Davide Piovesan To study the effect of damping due to branching in trees and fractal structures, a harmonic analysis was performed on a finite element model using commercially available software. The model represented a three-dimensional (3D) fractal treelike structure, with properties...

...Shereen M. Faraj; Shaimaa M. Abd Al-Baqi; Nasreen R. Jber; Johnny Fisher Porous silicon (PS) has become the focus of attention in upgrading silicon for optoelectronics. In this work, various structures were produced depending on the formation parameters by photo-electrochemical etching (PECE...

... composites have been extensively used in various structural applications; however, there is need to further enhance the strength and stiffness of these polymer composites. Carbon nanotubes (CNTs) can be effectively used as secondary reinforcement material in polymer based composites due to their superlative...

... using outdated Industrial Age textbooks, proclaiming that we still do not know what an atom looks like.” As demonstrated by the illustrations in this book, we are able now to see atomic structures on the nanoscale, due to atomic force microscopy. Her main message is that, since nanomanufacturing...
