The effects of microstructure, grain and grain boundary (GB) properties on predicted damage paths and indicative crack propagation direction have been examined for a polycrystalline material using mesoscale finite element simulations. Numerical analyses were carried out on a compact tension specimen geometry containin…
An asymmetrical chiral metamaterial at microwave frequency is constructed by using four double-layered L-shaped strips which are rotated by 900 with respect to their adjacent metal strip. These different size strips allows another degree of freedom in the equalizing the orthogonal components of the electric fields at…
A junction of lattice-matched cubic semiconductors ZnTe and PbSe results in a band alignment of type I so that the narrow band gap of PbSe is completely within the wider band gap of ZnTe. The valence band offset of 0.27 eV was found, representing a minor barrier during injection of holes from PbSe into ZnTe. Simple li…
Corrosion at the bilge due to direct contact with the seawater is an issue which is necessary to be taken into account. The problem can be solved by giving combined protection such as coating and cathodic protection impressed current cathodic protection (ICCP). For broader range, there is occasionally a possibility of…
To ensure the high performance of graphene-based field effect transistors (GFETs) on flexible substrates, an uniform and manufacturable dielectric film with good electrical properties is needed. Thus, electrical characterization of the dielectric film on graphene on flexible substrates is very important for the develo…
A layered structure compound LiNiO2 material is synthesized by the solid-state reaction method under air atmosphere in the temperature range from 750 °C to 850 °C using Li2CO3 and NiO as the starting materials for 20 hours. The physical properties of the synthesized powder are investigated by X-ray diffraction (XRD),…
Three types of green compacts were formed by using applied loads of 1, 2, and 3 ton, respectively, and were sintered at 980 ◦C. The sintered ceramics with an applied load of 1 ton had the highest volume shrinkage, but the density was almost similar for all ceramics. There was no change in the crystal structure for all…
AMn3V4O12 (A = Ca, Ce, and Sm) compounds with a perovskite structure are synthesized at high pressures and temperatures. The crystalline structure of these compounds (space group $$Im\bar 3$$ Z = 2) is determined via X-ray analysis. If ions in the A sublattice are changed in the order Ca2+–Sm3+–Ce3+, the valence is re…
This paper presents a study of the friction properties of polymeric composite materials reinforced with unidirectional carbon fibers having different stratified structure.So, the composites are complex and versatile materials but their behaviour in practice is not fully studied.For instance, these polymeric composite…
This paper presents a review on recent developments and future trends in zinc oxide thin film transistors (ZnO TFTs) together with challenges involved in this technology. It highlights ZnO TFT as next generation choice over other available thin film transistor technology namely a – Si: H (amorphous hydrogenated silico…
Orthopedics biomaterials are intended for implantation in the human body and substituted or help to repair of bones, cartilage or organ transplant, and tendons. At the end of the 20th century, the availability of materials for the manufacture implants used in medicine has been the same as for other industrial applicat…
Luminescent complex mixed-ligand compounds of europium(III) with quinaldic acid and phosphor- containing neutral ligands have been obtained. Their composition and structure have been determined. The thermal and spectral-luminescent properties of the obtained complex mixed-ligand compounds of europium( III) have been s…
The purpose of this study is to determine the impact properties, chemical resistance and morphology of TPU/PVC blend in order to be used as potential material to fabricate bedpan. TPU and incorporation of PVC in TPU was done by melt-mixing method. The blends of TPU/PVC from melt mixing were then undergoing hot press c…
Abstract In this article, the influence of ion irradiation on temperature dependent electrical transport characteristics of thin graphite flakes was investigated. Thin graphite flakes were exfoliated by mechanical exfoliation method. Scanning electron microscopy was used to study surface morphology of the graphite fla…
By applying the sol-gel method, we fabricated Ba1−x Eu x TiO3 (BET) ceramics as a single peroveskite phase in the composition range of x = 0 ~ 0.20. The BET ceramics displayed a ferroelectric phase transition temperature that changed from 120 ◦C to 80 ◦C, and exhibited the coexistance of the tetragonal, and cubic stru…
Gold nano particles (GNPs) concentration dependence of the energy transfer occurs between the fluorophores and GNPs is investigated. In the case of theses pairs, GNPs can enhance or quench the fluorescence of fluorophores depending upon the relative magnitudes of two energy transfer mechanisms: i) the plasmonic field…
RESUMO A soldagem a arco submerso é um processo de fabricação bastante utilizado na indústria naval, a qual apresentou um crescimento significativo nos últimos anos no país. Este trabalho apresenta um estudo detalhado da interação química que ocorre entre o metal de base, o metal de adição e o fluxo de soldagem em um…
To improve the efficiency of the multimode hybrid energy storage system (HESS), a novel adaptive mode control strategy (ADCS) based on logic threshold and hysteresis control strategy is proposed. The operating modes of the multimode HESS are first analyzed. Then, the adaptive target voltage of the ultracapacitor and t…
CuGa1-×Sn×O2 (0 ≤ × ≤ 0.1427) samples were synthesized by convenient hydrothermal method. The crystal structure and optical properties were also investigated. Results revealed that the CuGa1-×Sn×O2 samples are delafossite oxides with a rhombohedral (space group R-3m) structure; the XPS spectra confirmed that the valen…
The effect of small copper additions (to ∼6 at %) on the distribution of iron ions in six crystallographic sites of the unit cell of the main magnetic phase (PrDy)2(FeCo)14B has been detected. An increase in the copper concentration leads to a decrease in the 8j 1 site occupation by iron ions. Independently of the pre…
