Stenosis is a localize plaque that cause the vessel wall narrowed and causing an alternation in the flow structure which consequently reduced the fluid flow passing to the other organs and tissues. Previous researchers had proven that the formation of stenosis could disturb the normal ... En savoir plus

The aim of this research is to study the electrostatic properties of heterogeneous media that have fractal geometries. Currently, composite dielectrics are assumed to have regular geometric structures (integer-based dimensions) and an isotopic, homogeneous dielectric permittivity; but, ... En savoir plus

The dielectric properties of heterogeneous media are of increasing interest as many applications exploit the usage of dielectric property detection in bio-imaging, scanning, microwave tomography and other electromagnetic applications. Using Laplace’s equation for non-integer dimensions, ... En savoir plus

Introduction: Wireless power transfer (WPT) is an emerging technology for charging implantable devices, industrial devices, and consumer electronics. It can be categorized as short-distance, mid-range, and long-distance WPT based on the distance between the transmitter (Tx) and the ... En savoir plus

Microstrip line and rectangular waveguide are widely used as transmission lines in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics to study electric field distribution and scattering parameters of ZnO-PCL nanocomposites when ... En savoir plus

Transplantation of organs and tissues remains the solution for repair of damaged tissue, yet the shortage of donor human organs for transplant is another issue as well. In the field of regenerative medicine, several regenerative technologies have recently been developed using various ... En savoir plus

Surface and solution kinetics for redox systems can be reliably and accurately studied using hydrodynamic electrochemical methods, particularly a rotating disk electrode (RDE). The RDE consists of a disk electrode usually made of glassy carbon or noble metals imbedded in a rod of ... En savoir plus

The detection of early corrosion is a key issue to mitigate the damage induced by metal corrosion. The optical fiber corrosion sensor based on a side-polished polarizer is realized recently. The polarizer is fabricated by sputtering a Fe film on a side-polished single mode fiber. The new ... En savoir plus

Large strain is crucial for piezoelectric ceramics to be used as actuators. In this work, a piezoelectric composite with core-shell structure is proposed to pursue high strain at a low applied electric field. The core of the piezoelectric composite is typical ferroelectric material, ... En savoir plus

Intermetallic particles (IMPs) in Al alloys play an important role in localized corrosion processes, and largely affect the service safety and reliability of the alloys. However, most of the experimental methods used so far only probe active corrosion sites on a projected two-dimensional ... En savoir plus
