The present study investigates the electrical conductivity and dielectric properties of untreated and alkali-treated Roystonea regia natural fiber–reinforced epoxy composites at different frequencies along with compression and water absorption properties. Fiber was treated with 5% NaOH and characterized by chemical, t…
The structural and magnetic order are the decisive elements which vastly determine the properties of smart ternary intermetallics such as X2YZ Heusler alloys. Here, X and Y are transition metal elements and Z is an element from the III-V group. In order to give a precise prescription of the possibilities to optimize t…
A novel non-porous low- k dielectric, fluorocarbon, deposited by new microwave excited plasma enhanced chemical vapor deposition was successfully integrated into Cu damascene interconnects for the first time. Electrical characteristics of fluorocarbon/Cu damascene lines are investigated. A compatible line to line leak…
A novel and simple approach is reported to fabricate ZnO nanorods in the presence of nano Preyssler polyoxometalate. The morphology and size of these nanorods were characterized using transmission electron microscopy and X-ray diffraction. The performance of nano form of Preyssler was compared with bulk form. Results…
The magnetization isotherms were used to study the superparamagnetic-like behaviour in polycrystalline (powder) RE2WO6 tungstates (where RE = Nd, Sm, Eu, Gd, Dy, Ho and Er). The magnetization isotherms of the majority tungstates under study revealed both the spontaneous magnetic moments and hysteresis characteristic f…
We report on the electrical properties of carbon nanotube (CNT) via interconnects with improvement in contact formations between the CNT via and metal electrodes. For the improvement of the bottom contact formation, a TiN/TaN multilayer on a Cu bottom wiring layer is applied to suppress formation of a highly resistive…
High-temperature composite materials and coatings developed in the RIAM, specifically construction composite materials with glass, glass-ceramic, and ceramic matrices, for use at 700–1500°C, ceramic composites on the basis of poly-carbosilanes, erosion resistant coatings with the effect of thermal control for heat shi…
Grain refinement studies in titanium have gained significant interest owing to its importance as a biomaterial. Severe plastic deformation techniques have been widely applied for grain refinement in metals and are capable of producing ultra fine and nano sized microstructures. In this study, repetitive shear deformati…
In order to clarify the best condition for the growth of iron chalcogenide superconductor thin films, we investigated the effect of the substrate on the transport and structural properties of films. Thin films of FeSe 0.5 Te 0.5 grown by pulsed laser deposition were characterized by DC electrical resistivity, Hall eff…
A series of BaTiO3/Ba1 − x Sr x TiO3 (BT/BST) superlattices were prepared by pulsed laser deposition on MgO substrates with a constant period of 80 Å (40 Å BT and 40 Å BST) and varying compositions of the BST layer so that the Ba/Sr concentration ratios were 0/100, 30/70, 40/60, 50/50, 60/40, 70/30, 100/0. The soft mo…
One of the methods of increasing the corrosion resistance of zinc coatings is the application of zinc and aluminium alloy baths in the metallization process. The coatings obtained are characterized by much better corrosion resistance thanks to the combination of aluminium properties, i.e. the barrier protection provid…
An accurate X-ray diffraction study of Sr 3 TaGa 3 Si 2 O 14 (STGS) crystal ( a = 8.3023(10) Å, c = 5.0853(2) Å, sp. gr. P 321, Z = 1, R/wR = 0.59/0.52%, 4004 independent reflections) is performed. The use of two independent data sets obtained on diffractometers with point and 2D detectors made it possible to determin…
The band offset at the Cu 2 O/ZnO heterojunction was estimated both experimentally and theoretically following the procedure of core-level spectroscopy. The heterojunction was fabricated by electrochemical deposition, and the band offset was determined by X-ray photoelectron spectroscopy. For the theoretical calculati…
The synthesis route at low temperature for Ce-doped yttrium aluminium garnet (YAG:Ce) phosphor is described. Its photoluminescence efficiency and quenching temperature dependence characteristics are found to be comparable to the imported one. YAG:Ce shows least thermal quenching among the several blue LED phosphors [C…
This paper describes leading-edge research to explore and demonstrate new and unique nanoscale magnetic composites for high-frequency RF applications. Passivated cobalt nanoparticles were chemically synthesized and dispersed in epoxy to fabricate nanocomposite thick films. The high permeability comes from enhanced cou…
Precise modeling of PMSM needs considering the nonlinear characteristics of the hard and soft magnetic materials used in the machine. Therefore nonlinear machine models with time-variant parameters are used. Usually saturation is modeled in the field oriented coordinates assuming that the d-axis flux affects the q-axi…
Microbubbles have the potential to be used in many applications in different fields, especially in food, biomedical, and environmental sciences. However, to produce microbubbles with relatively long-term stability is difficult as they are inherently unstable entities. Hydrophobins are naturally occurring proteins that…
In this paper, first the fundamental concept of nano-optical biosensing is studied. Since Raman scattered signal is very weak to be recognized by current measuring equipments, the signal must be amplified. SPR and LSPR are utilized to enhance the incident field of the target molecules, to improve the sensitivity of th…
Nanofiber ACFs composed of adhesive resins, conductive particles, and nanofibers were demonstrated for ultra fine pitch COF packages. PAN nanofibers and PAN nanofiber containing conductive particles inside the fibers were successfully produced using electrospinning methods. The effects of nanofiber thickness and struc…
Textured high-Curie-point lead-free piezoelectric ceramics, CaBi 2 Nb 2 O 9 (CBN), were prepared by the tape casting method. Highly textured ceramics with a single phase and 95% Lotgering factor were obtained by the templated grain growth (TGG) technique. The textured CBN ceramics had a higher piezoelectric constant (…
