The topological properties of a multiband topological superconductor in two dimensions are studied, when the latter is obtained by introducing electron pairing in an otherwise topological insulator. The type of pairing, doping and Fermi surface topology play an essential role. Considering the Andreev reflection proble…
Nano-materials surface engineering is the key constituent for advanced manufacturing and high performance engineering components. Zn-Cr2O3-SiO2 nanocomposite coatings were produced from electrolytic chloride bath solution on the surface of mild steel. The surface morphology, structural analysis and composition of the…
Due to the increasing demand for high-efficiency electric motors and the maturity of vector-controlled motor drives, the Synchronous Reluctance Motor (SynRM) has received an increasing amount of attention over the past few years. Classically, SynRMs are analysed using analytical models which require little computation…
There will be 50 diagnostic systems installed on ITER. All have been implemented with great success on experimental fusion reactors around the world. Despite this deep experience, implementation of diagnostic systems on ITER remains very challenging. Structural, nuclear and optical engineering challenges arise from lo…
Three-component condensation of fullerene C 60 with sarcosine and 4-(4-bromo-3,5-dimethyl-1 H -pyrazol-1-yl)benzaldehyde under the conditions of the Prato reaction has afforded new fulleropyrrolidine; the product structure has been confirmed by IR and NMR spectroscopy as well as mass spectrometry.
This research paper puts forward the electrical behavior of vertical channel organic thin film transistors (V-OTFTs) using organic module of Atlas 2-D numerical device simulator. The electrical characteristics and performance parameters of pentacene based V-OTFT is analyzed. The devices are compared for different line…
This paper proposes a modified lattice configuration of aluminum nitride (AlN) based bulk acoustic wave bandpass filter, which effectively broadens the pass band width without sacrificing the insertion loss and out-of-band rejection. The novel topology comprises two auxiliary inductors paralleled in the balanced input…
The kinetics of carbon dioxide and propylene oxide copolymerization was investigated in order to obtain Arrhenius parameters for the reaction in the presence of the efficient binary catalytic system (salen)Co(DNP)/[PPN]Cl. The reaction rate was followed by measuring the uptake of carbon dioxide during copolymerization…
The surfactant assisted hydrothermal process for selective preparation of copper nanosheets and ultralong microwires by reducing Cu 2+ with 2-(bis-phosphonomethylamino)propionic acid (dpc) under the action of cetyltrimethylammonium bromide (CTAB) or polyvinyl pyrrolidine (PVP) is presented. X-ray powder diffraction (X…
Owing to getting rid of brushes and slip rings, the magnetic-field modulated brushless double-rotor machine (MFM-BDRM) can be a promising candidate for the electrical-continuously variable transmission (e-CVT) in hybrid electric vehicles (HEVs). However, since there are many magnetic-field harmonics with the high rota…
Planar switched reluctance motors (PSRMs) have the merits of simple structure, low cost, low heat loss, high precision, ease of manufacture, and strong adaptability of harsh environment, which directly transform the mechanical energy to electromagnetic energy available to planar motions without mechanical transmission…
Although it is possible to improve the optoelectronic conversions of solar cells through the construction of one-dimensional nanostructures on their front surfaces, much effort at such fabrication has led to only modest increases in conversion efficiencies. In this study, we employed i-line lithography and ion implant…
Accumulation and metabolism of purine alkaloids in leaves of maté (Ilex paraguariensis) were investigated. In winter, leaves accumulated caffeine but not theobromine, indicating that caffeine is the end product of purine alkaloid synthesis in maté. To elucidate the purine alkaloid metabolism in maté leaves, the metabo…
This paper deals with the multi-objective optimization of a transverse flux machine with claw-pole and flux-concentrating structure (CPTFM), which is especially suitable for low-speed and high-torque applications due to its high pole pair number. Compared with conventional radial flux machine, the main flux path in CP…
Saliva studies are of great interest in the area of biorheology. This human body fluid plays an essential role in dysphagia since it is directly related to the swallowing process and to the rheology of food bolus. The aim of this work was to discuss the capillary breakup extensional properties of acidic and mechanical…
Compared to periodic crystals, quasicrystals have higher point group symmetry and are more favorable in achieving complete band-gaps. In this report, a top-cut prism interferometer is designed to fabricate ten-fold photonic quasicrystalline structures. By optimizing the exposing conditions and material characteristics…
In this paper, we studied defect discovery and defect review using back-scattered electron (BSE) images. We found that some defects can only be effectively imaged with BSE mode such as hafnium oxide remain at metal gate chemical mechanical polishing (CMP) in the gate last high-k metal gate (HKMG) process. It can also…
An investigation of bandwidth improvement for artificial magnetic conductor (AMC) structure based on square patch array by using multiple slots technique is presented. The technique is proposed in overcoming the nature characteristic of square patch as a unit cell of AMC structure which has narrowband bandwidth respon…

Various parameters of Solid Pressure Vessel are designed and checked according to the principles specified in American So…
AlGaN/GaN HEMT is one of attractive candidates for next generation high power devices because of high carrier mobility in 2DEG channels and high breakdown voltage due high critical electric field. In order to apply the AlGaN/GaN HEMTs for power switching applications the normally off operation is required. Enhancement…
