Electromigration (EM) in on-chip metal interconnects is a critical reliability failure mechanism in nanometer-scale technologies. This work addresses the problem of EM on signal interconnects within a standard cell. An approach for modeling and efficient characterization of cell-internal EM is developed, incorporating…
This paper discusses the design and implementation of circle shaped loop antena to measure partial discharge (PD). The loop antenna is designed to measure PD induced EM wave in air and liquid insulation. The PD in air and liquid induces EM wave in the frequency range up to 100 MHz and 200 MHz, respectively. The circum…
Artemisia montana Pampan (Compositae) (AMP) contains various compounds, including phenolic acids, alkaloids, and essential oil. It has been widely used in oriental medicine due to a variety of biological effects. However, the biological activity of the essential oil from AMP (AMPEO) on skin has not been investigated.…
We have fabricated Co-Pt cylindrical nanostructures comprised of a pair of nanotube and nanowire segments via direct electroplating into anodic alumina (AAO) membranes. The fabrication of such nanostructures is possible due to the penetration of sputtered gold (Au) nanoparticles inside the template, which serve as nuc…
AC magnetic properties and core loss behavior of differently prepared Fe-P sheets have been analyzed in this paper. Furthermore, the results have been compared with non-oriented silicon (Si) steel. The coercivity, magnetic flux density, and permeability measurements in dc magnetic field show Fe-P has better soft magne…
It is proposed to use a generalized matrix averaging (GMA) method for calculating the parameters of an effective medium with physical properties equivalent to those of a set of thin multiferroic layers. This approach obviates the need to solve a complex system of magnetoelectroelasticity equations. The required effect…
We believe that a better understanding of supramolecular associations could lead to improved understanding and control of biological processes for new medical applications. "
We theoretically reveal a new amplification mechanism of terahertz and far-infrared radiation in graphene under interband pumping. It is enabled by indirect interband electron transitions, where in the photon emission is preceded or followed by disorder scattering. The emerging contribution to the optical conductivity…
BACKGROUND: Radix Ophiopogonis polysaccharide (ROP), a highly hydrophilic macromolecule, has a unique anti-ischemic action in the myocardium. One of the main problems with its use is its relatively short half-life in vivo. To solve this problem, injectable long-acting drug delivery systems, which combine mono-PEGylati…
An overview of the recent development of a multiscale simulation of amorphous polymeric materials at the bulk density is presented. Poly(ethylene oxide), (PEO), (CH 3 O-[CH 2 -CH 2 -O] n CH 3 ) was selected to illustrate the method. The model starts from an ab initio quantum chemistry to obtain the statistical weights…
(SSFO) films were epitaxially grown on MgO substrates by pulsed-laser deposition. X-ray diffraction, atomic force microcopy, and optical spectra investigations reveal that the lattice and band structure properties of the SSFO films can be modified significantly by varying the Fe content. With Fe content increasing fro…
Poly(ethylene terephthalate) (PET) is the most widely used plastic in beverages packaging. It is also the most recycled plastic in the world. It is estimated that 6 million tons of PET are recycled (rPET) each year worldwide. Recycling of this material by melt processing has been the subject of many studies, in order…
The results of experimental and theoretical studies of steel 09G2S deformation and fracture laws in a wide range of strain rates and temperature variations are given. The dynamic deformation curves and the ultimate characteristics of plasticity in high-rate strain were determined by the Kolsky method in compression, e…
This paper deals with the fundamental theoretical background of a 1-D parametric magneto-dynamic (PMD) model, which analytically solves the interdependence of the magnetic field and macroscopic eddy currents inside a thin soft magnetic steel sheet (SMSS). Furthermore, the loss calculation using the discussed model is…
This paper presents a vector hysteresis model based on micromagnetic theory. In this model, a magnetization state of a magnetic material is described by a collection of single-domain particles, and magnetic reversal processes due to domain-wall motions are treated approximately as a magnetization flip. The present mod…
The MnxZn1-xFe2O4nanoparticles with (x = 0, 0.25) , and 0.5 were synthesized by a chemical coprecipitation method. The X-ray diffraction (XRD) patterns were well fitted with single-phase spinel ferrite structure using Rietveld analysis as Fd-3m space group. The average crystallite size of the nanoparticles estimated f…
This paper describes a methodology to characterize soft magnetic materials for a core loss model, which is capable of predicting both instantaneous and average loss. The characterization method dispenses with the need for close loop control, which significantly extends the range of non-linearity and frequency that can…
BACKGROUND: Cell culture conditions can greatly influence the results of nanoparticle (NP) uptake assays. In this study, 10 nm gold nanoparticles (AuNPs) and RAW 264.7 macrophages were used as a model system, while instrumental neutron activation analysis (NAA) was used as the elemental analysis technique to determine…
Multiple-Level Cell (MLC) storage provides increased capacity and hence reduced cost-per-bit in memory technologies, thereby rendering such technologies suitable for big data applications. In Phase-Change Memory (PCM), however, MLC storage is seriously hampered by the phenomenon of resistance drift. We present a reado…
In this research, the effect of long chain branching (LCB) and polymerization conditions on thermal, mechanical, and rheological properties of polyethylene synthesized via a metallocene polymerization was studied. The LCB was varied in the range of 0.64–1.14 per 10 4 atoms of C. 13 C NMR spectra showed that the distri…
