Modification of the spectral response of a periodically coupled metallic nanostructure is reported. A thin SU‐8 dielectric cavity was fabricated on a nanopatterned gold film. Additional resonance peaks are observed in the transmitted spectrum due to the interaction between excited surface plasmon polaritons (SPPs) and…
This paper deals with an adaptive hysteresis controller for the Switched Reluctance Machine (SRM). The classical hysteresis controller provides a high bandwidth, good robustness but it's characterized by a variable switching frequency. This latter causes the injection of high frequency harmonics into the system that c…
The WPI-NaCas-GLY antimicrobial film takes full advantage of the controlled release of active or antimicrobial agents as well as demonstrates a great potential for functioning as an alternative biodegradable polymer in practical applications. The moisture sorption kinetics of the film as an important carrier of active…
A novel and versatile uniplanar dual composite right-/-left handed (D-CRLH) microstrip line is demonstrated. The dual behavior is achieved by constructing complementary split ring resonators (CSRR) in series with parallel inductive-capacitive loading on a conventional microstrip line. The main advantage of the propose…
The piezoelectric biosensor have been widely used in ultra-small mass detection of biomolecular, based on PZT piezoelectric material can create a variety of compositions geometrically; it could widely develop a high-frequency resonator and measure the change of the slightest mass while improve the limited detection si…
Cu-Pb, Cu-Cd, and Cu-Zn thin films were electrodeposited from a simulated chloride wastewater solution using stainless steel rotating disc electrode. The linear sweep voltammograms of the single metallic ions show that electrodeposition of these ions was under mass transfer control due to the well- defined plateau obs…
Polyaniline (PANI) as active material of batteries possesses excellent electrochemical reversibility. It is a promising candidate for a rechargeable battery with a high performance. However, current collectors become a manufacturing bottleneck of PANI battery. In this paper, the effects of five current collectors: sta…
Corrosion inhibition of carbon steel in normal hydrochloric acid solution at 303 K by new thiazole derivatives has been studied by a series of known techniques such as weight loss, polarisation and electrochemical impedance spectroscopy (EIS). The experimental results have showed that this organic compound revealed a…
The corrosion behavior of Q235 carbon steel in simulated concrete pore solution was investigated by electrochemical impedance spectroscopy (EIS) and electrochemical noise (EN) techniques. The equivalent circuit, statistical analysis, wavelet transform, chaos theory and cluster analysis method were employed to research…
In this study, Faba bean stalk was liquefied for the production of biopolyols and polyurethane (PU) foams. The influences of various reaction conditions on biopolyols and PU foams were examined. Furthermore, the property relationships between biopolyols and PU foams were investigated. Biopolyols produced under the liq…
The production of materials based on mixtures of three different resins and the application of the obtained materials as electrets are proposed.
We present the results of experimental studies of the temperature-dependent real part of the dielectric constant and the electrical conductivity for Tl4HgI6 and Tl4CdI6 crystals. We show that the crystals under study manifest anomalous behaviors of the both physical properties in the same temperature regions. The latt…
To develop the post Cu-CMP cleaner, we investigate galvanic corrosion of Co as used barrier metal by electrochemical measurements. To elucidate relationship between cleaner composition and galvanic corrosion, corrosion potential is investigated by Tafel plot and corrosion current is measured by Liner Sweep Voltammetry…
Numerical modelling of photovoltaic solar cells is an important strategy to test the viability of proposed physical structures and their performance. This article introduces the concept of numerical simulation and explain the relevant physical models for the inside physical phenomenon like generation, recombination an…
The effects of colloidal silica on the CMP of Molybdenum (Mo) are investigated in different slurries with H2O2as oxidizer. It is found that both RR (removal rate) and SER (static etching rate) decrease after adding colloidal silica into the alkaline slurry. The adsorption between the colloidal silica particles and Mo…
BACKGROUND AND AIM OF THE STUDY: The use of extracellular matrix (ECM) from the porcine small intestinal submucosa has shown promising results in reconstructive heart surgery. The study aim was to compare native and ECM tricuspid valves with regards to tricuspid leaflet coaptation geometry and force development in the…
We present the design and the proof of concept of a self-powered System-on-Chip temperature sensor with wireless communication interface integrated in the shape of a heat-sink. The proposed solution is based on a thermo-harvesting module that scavenges the energy required to operate from the target device under monito…
Fe, Fe94Si6, Fe98C2, and Fe95B5(at. %) single-crystal thin films of bcc(001) orientation are prepared on MgO(001) substrates using an ultrahigh-vacuum magnetron sputtering system. The influence of magnetic anisotropy on the magnetostriction under rotating magnetic field is investigated. Fe, Fe94Si6, and Fe98C2films sh…
This paper describes fabrication and characterization of self-packaged microbolometers on a flexible substrate. Amorphous silicon (a-Si) was used as the sensing material and the entire detector was device-level packaged in a vacuum cavity with an aluminum oxide packaging layer which can withstand up to 10 atm pressure…
Despite studies indicating the differential use of stitch density with respect to textile apparel, there is little information on the effect of stitch type and stitch density (stitches/cm or spc) on the seam properties of leather clothing. An experimental investigation of the effect of two different types of stitches…
