The electromagnetic properties of a circular silver nanowire grating placed over a dielectric slab are investigated using the Maxwell formalism. The scattering properties are analyzed for the normally incident H-polarized plane wave. The lasing properties are studied for the same configuration however the dielectric s…
A modified version of the Intelligent Water Drops algorithm (MIWD) was developed then used to determine the most stable configurations of Lennard-Jones (LJ), Binary Lennard-Jones (BLJ) and Morse Clusters. The algorithm is unbiased in that it uses no a priori cluster geometry information or cluster seeds. Results for L…

Rv0045 is a serine esterase from M. tuberculosis whose physiological substrate and biological role are unknown. We have prepared a series of novel fluorogenic esterase substrates based on a fluorescein scaffold. Each compound was characterized by high resolution mass spectrometry, 1H-NMR, and 13C-NMR. The resulting li…
In this study, the effect of variety of Nano- additives doping on the hydration resistance of the MgO-CaO system was investigated. Samples were prepared from calcined dolomite and magnesite. Nano-additives that contained cations with various valences (trivalent and tetravalent) used as a dopant. The bulk density, appa…
We show that parity-time symmetry offers unique opportunities for achieving exciting phenomena, such as cloaking and negative refraction. By coating an object with a parity-time symmetric metasurface, i.e., a metasurface with appropriately balanced loss and gain, it is possible to achieve complete scattering cancellat…
Although the finite element method is a good tool to analyze skin-pass rolling, it is hard to be applied in the field because of its long calculation time. In the current study, simple numerical models were developed for the prediction of roll force and residual stress profiles along the strip width. These models are…
In this study, C-doped TiO2 nanofibers were fabucated by electrospinning. The different amount of carbon was added into the nanofibers by using chitosan and glucose. With different amount of carbon and different atmosphere and fibers were calcined at 500°C, and then the optical characteristics of C-doped TiO2 nanofibe…
There are several reliability problems, while Cu wire bonding has been used instead of Au wire bonding in microelectronics packaging. A previous work indicated that after autoclave test maintaining at 394 K, 100% relative humidity and 0.2 MPa for 300 h, a shear strength of Cu wire bonding decreased to about half that…
We proposed and demonstrated a scheme to enhance and tune absorption properties of conventional microwave absorbing materials by metamaterials. First, an interleaved metamaterial array operating at several frequencies is proposed. Then, the artificial material is placed on the back of a pyramidal absorber. At last, bo…
In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous steps. The proposed acoustic leaky-wave antenna has the frequency…
Second harmonic wave in the microwave range is generated by nonlinear effects in a plasma-metamaterial composite. The metamaterial is an array of double split ring resonator whose negative permeability range includes the frequency of the fundamental wave. Asymmetry that induces the second harmonic wave arises from pla…

A numerical approach based on the Volume Electric Field Integral Equation is presented for investigating the permittivity profile of dielectric scatterers able to synthesize a determined near-field distribution. Starting from the cloaking design approaches available in the literature, in this paper, the main concept i…
Capacitance and tan δ measurements are usually carried out to check the healthiness of an insulation. Measuring equipment based on different methodologies to test insulation in cables, transformer bushings etc. are available. This paper presents the development of such a measuring equipment for a high voltage (HV) lab…
The transmission and reflection coefficients of graphene surface waves, owing to the discontinuities of its substrate, are systematically studied and numerically computed in this paper. In essence, the propagation properties of these graphene-supported waves are theoretically extracted, revealing their strong dependen…

In this paper a study on the magnetostrictive-piezoelectric composite material with different configuration in a variety of external magnetic field changes was presented. An experimental setup for investigation of properties of magnetostrictive-piezoelectric materials was prepared. The hybrid structure was made of mag…
Infrared spectroscopy provides chemical information of biomolecules by detecting their vibrational fingerprints. Here, we use graphene plasmons to enhance infrared absorption and to demonstrate a tunable biosensor with high sensitivity for label-free and chemically-specific detection of protein monolayers. We show tha…
Stretchable wires and electrodes were printed on a textile substrate using a polyurethane-based conductive paste with silver fillers loading. Variation in their electrical resistivity was examined during a cyclic uniaxial tensile test at 10 % strain. The resistivity decreased to approach an equilibrium value when the…
