The reliability of interconnects continues to be a formidable challenge as dimensions shrink from generation to generation. In this paper we demonstrate barrier/seed scaling, enabled by HCMregIONX PVD technology. We report high electromigration activation energy of ~ 1 eV, and Jmax> 6 MA/cm2, exceeding the ITRS 2007 r…
Highly transparent and conductive scandium doped zinc oxide (ZnO/Sc) films were prepared on Corning glass 7059 substrates by the sol-gel technique. The influence of scandium concentration (0–1.5 wt. %) and annealing temperature (300–500 °C) on the structural, optical and electrical properties was investigated. The ave…
The natural cell cytoskeleton provides critical mechanical support for lipid bilayers using a network of actin fibers. As a step towards fabricating artificial cells, functional nanofiber networks were created to mimic the chemical and mechanical environment provided by the actin network. Lipid bilayers were formed on…
In this paper, for developing analytical and semi-analytical methods to evaluate band structure in photonic quasicrystals the perturbation theory is examined. It is shown that more isotropic and complete photonic band gap can be observed under low dielectric contrast for photonic quasicrystals in comparison with ordin…
An alternating current (AC) of 60 A with a frequency of 1 kHz was imposed on the hypereutectic Mg-4.8 mass% Si melt during solidification in order to modify the primary Mg2Si crystals. The liquidus and eutectic temperatures of the Mg-4.8 mass% Si alloy are 761°C and 638°C, respectively. In order to investigate the eff…
A temperature-monitoring system based on radiofrequency identification (RFID) has been developed for extending the maintenance period of the nuclear material packaging for storage and transportation. The system consists of tags, readers, and application software. The tag, equipped with a temperature sensor, is attache…
A 67-year-old woman with metastatic colorectal cancer was given her first oxaliplatin infusion as part of the XELOX protocol. She developed chest pain with ECG changes leading subsequently to a diagnosis of coronary artery spasm. To our knowledge, this is the first report of oxaliplatin-induced coronary artery spasm.
The QUENCH-14 experiment investigated the effect of M5® cladding material on bundle oxidation and core reflood, in comparison with tests QUENCH-06 (ISP-45) that used standard Zircaloy-4 and QUENCH-12 that used VVER E110-claddings. The PWR bundle configuration of QUENCH-14 with a single unheated rod, 20 heated rods, an…
The effect of the addition of rare earth metals (REM) to the weld metal on the microcracking susceptibility in the multipass welds of alloy 690 was examined by using the La or Ce containing filler metals. The amounts of the La and Ce in the filler metal were varied in several levels. The microcracking susceptibility o…
Synthesis and characterization of SiO2 doped bismuth titanate ceramics were investigated. Four investigated compositions belonging to the system Bi2O3-TiO2-SiO2 are located in the section Bi4Ti3O12-SiO2, near by it and in the binary Bi2O3-TiO2 system. Melt quenching was applied for synthesis of SiO2 doped bismuth tita…
The results of investigations of the effect of modification and cooling rate on the macrostructure of castings made from IN-713C nickel superalloy were described. As a modifier, cobalt aluminate CoAl2O4 in composition with aluminium powder and colloidal silica was used. Changes in the cooling rate were obtained by the…
AbstrAct Purpose: The aim of this paper is to show influence of technological parameters (temperature and gas stream intensity) of low-temperature chemical vapour deposition (LCVD) on optical properties and morphology of polyazomethine thin films. Design/methodology/approach: Thin layers of poly (1,4-phenylene-methyle…
The widespread applications of chlorofluorocarbon (CFC) in industry including refrigeration, foam blowing agent and cleaning agent cause severe damage to the ozone layer and might contributed to global warming. Various methods were developed to find CFC alternatives or its environment’s destruction. Among them catalyt…
Several of the typical RF absorbing materials utilized in particle accelerator environments have DC electrical conductivities that decrease significantly when cooled to cryogenic temperatures. If such RF absorbers are in close proximity to a beamline, they are prone to collecting static charge and may deflect the part…
Tatara is traditional iron making method developed around San-in area in Japan. Typical product of Tatara is Japanese sword, which is tough and strong and is also known as an art object. It is said that Japanese sword cannot be produced without Tatara iron. Thus microscopic observations of Japanese sword attracted res…
A physically motivated and thermodynamically consistent formulation of higher-order gradient plasticity theory is presented. This proposed model is a two non-local parameter framework that takes into consideration: (1) the presence of plastic strain gradients, which is motivated by the evolution of dislocation density…
We present a new method for the statistical analysis of random telegraph signals. Simulations show the good features of the method which is a powerful tool for evaluating the impact of RTS on performance and reliability of electron devices. Its application to phase change memories will be discussed in order to success…
Certain elements, including noble metals, are identified to influence corrosion behavior of many metals in high-temperature water/steam and O2. We have previously reported effects of porous Pt coatings on the thermal oxidation of Zr, Fe, Ni, Cr, and GaAs in O2. Effects of Pt on oxidation of Zircaloy-2 in H2O have also…
The split-Hopkinson pressure bar experimental technique has been implemented to evaluate the high rate squeeze flow behavior of viscous fluids. In order to apply the classic Kolsky data reduction method, it is necessary to first ensure that the fluid specimen achieves equilibrium during loading. The timescales for the…
The effect of a juvenile hormone (JH) mimic R394 (ethyl 9-cyclohexyl-3, 7-dimethy l-2, 4-nonadienoate) applied topically on the abdominal tergum of silkworm (Bombyx mori L.) after the fourth ecdysis has been studied. JH R394 ranging from 1.0, 0.1, 0.01 µl / larva was applied at 48, 72 and 96 hours of V instar larva th…
