The grounding system is made of steel in most of developing countries. When the steel is eroded, it is a potential problem and very dangerous to the power system. So, the fault diagnosis on grounding grids is of great economic value for the safety operation in electric power system. In this paper, a simulation computa…
Although the improvement of tensile Modulus and thermal stability due to the addition of innovative organoclays to PLA were negligible, our investigation allowed to evidence that the preliminary preparation of an inorganic rich composite through in situ polymerization of lactyde gave a final morphology improved with r…
Surface‐Enhanced Raman Scattering (SERS) of amino acids has proven a challenging task. The SERS of biomolecules and the formation of a reliable SERS data‐base for medical application has shown to be a very challenging task for two reasons: first, the functional groups in proteins, lipid and sugars do not usually inclu…
Single crystals of the compound (NH4)3[UO2(CH3COO)3]2[UO2(CH3COO)(NCS)2(H2O)] (I) are synthesized, and their structure is investigated using X-ray diffraction. Compound I crystallizes in the monoclinic system with the unit cell parameters a = 18.3414(6) Å, b = 16.3858(7) Å, c = 12.4183(5) Å, β = 92.992(1)°, space grou…

Magnetic Fe3O4 nanoparticles have been synthesised by two methods: co-precipitation using a range of Fe3+ and Fe27+ raw materials; oxidative hydrolysis using various Fe2+ salts. X-ray diffraction analysis shows that most of the samples prepared by the co-precipitation method resulted in a mixture of two iron oxide pha…
Ni47Ti44Nb9 Shape Memory Alloys (SMAs) are widely considered for tightening applications. The alloy is composed of a NiTi SMA matrix containing niobium precipitates. A specific thermomechanical treatment strongly increases the transformation hysteresis in these alloys, what improves the tightening efficiency. Tighteni…
New photo-cross-linkable liquid crystalline polymethacrylate with 4-methoxybistolane side groups was synthesized and its thermally enhanced photoinduced molecular reorientation behavior was investigated using a linearly polarized (LP) UV light. Since the bistolane mesogenic side groups were axis-selectively photoreact…
We present the thermoelectric properties of individual PbTe nanowires grown by a vapor transport method. Temperature-dependent thermopower and electrical conductivity in PbTe nanowires were investigated. A PbTe nanowire {d = 136 nm) was found to have a Seebeck coefficient of −72 µV/K and electrical conductivity of 45…
Mn thin film deposited GaAs samples were implanted with 250 keV Ar+2 ions for various fluences 5×1015, 1×1016 and 5×1016 ions cm−2. Optical and structural properties of the samples have been investigated by using ultraviolet spectroscopy and X‐ray diffraction techniques. Optical absorbance of the implanted samples was…
The effect of the temperature for mixing epoxy-diane resin ED-20 with a curing agent, specifically polyoxypropylene triamine, the ratio of the components, and the introduction of diluting agents and fillers on the strength properties and water absorption of cured compositions is investigated. It was shown that, by usi…
Fe-doped ZnS (Fe:ZnS) nanocrystals were prepared by a liquid-solid-solution (LSS) method. The XRD results show that Fe:ZnS nanocrystals is crystallized with zinc-blende structure. The PL peaks of Fe:ZnS nanocrystals have a red-shift behavior as a Fe concentration increased. These results indicate that the tuning range…
Some investigations suggest that nanoparticles are potentially the most dangerous because they can also penetrate deeper into lung tissue than other large particles. However, some researchers declare that the research on security of environmental nanoparticles should be on the basis of the standardization of investiga…
We theoretically and experimentally demonstrated that direct backward third harmonic generation (THG) waves can be comparable in magnitude with forward THG waves in nanostructures, such as ZnO thin films and nanoparticles of CdSe and Fe3O4.
This paper presents the results of a fundamental finite-element based study of the crack-closure effects associated with combined residual and applied loading. First, an analytical expression for a representative two-dimensional residual stress field is derived. This residual stress field contains a central compressiv…
Plasma enhanced chemical vapor deposition was used to deposit hydrogenated silicon nitride (SiNx:H) thin films using two gas mixtures: SiH4/NH3AND SiH4/N2. NH3and N2gas flowrates were the only deposition parameters varied. Surface morphology of all the samples was observed with the help of atomic force microscopy (AFM…
Surface properties of polytetrafluoroethylene(PTFE) films fabricated by rf-magnetron sputtering system with UV surface treatment were investigated to increase water contact angle for their hydrophobic property. We found that the surface morphology and water contact angles of PTFE film modified as a function of the UV…
Galfenol (FeGaAlZrC) alloy ring was used for torque-sensing by detecting a leakage flux from the ring surface based on the inverse magnetostriction effect. This leakage flux changes depending on the magnetic parameter such as magnetostrictive strain(λ), residual magnetization (Mr), applied or residual stresses(σ) of t…
The strategic combination of bioactive molecules and drug delivery systems has the advantage of increasing the bioavailability of drugs while improving their safety profiles. Amidst the systems aimed to advance the pharmacological profile of otherwise unfavourable molecules, carbon-based nanomaterials (including nanop…
Pipelines and piping frequently suffer from metal loss that threatens their integrity and serviceability. Multiple repair options exist for straight sections of pipe; however, repair options for pipe fittings such as elbows and tees are typically limited to composite repair systems, or section replacement. The latter…
