Initial pathways and the kinetics of unimolecular dissociation of dimethylnitramine (DMNA) solvated in tetrahydrofuran (THF) are studied using density functional theory (DFT). The temperaturedependent kinetic rates at ambient pressure are estimated using variational transition-state theory (TST) combined with atomic b…
SrSn0.95Fe0.05O3 films were grown on oxidized silicon and quartz substrates by RF sputtering technique. The electronic transport and optical properties of the films were investigated. The temperature dependence of electronic conductivity has been analyzed quantitatively using Mott's small polaron hopping model in the…
In this paper we show the results of the cost model developed in LIMA project (Seventh Framework Programme, CN: 248909). The LIMA project is entitled “Improve photovoltaic efficiency by applying novel effects at the limits of light to matter interaction”. The project started in January 2010 and during this year a cost…
Recently, it has been shown possible to go around basic dispersion energy constraints that limit bandwidth of every passive metamaterial and construct a broadband active Epsilon-Near-Zero superluminal transmission line. A basic building block of this unusual transmission line is an active ‘tank circuit’ that contains…
During vascular surgical operations, there is a need for a simpler and more reliable method of temporary arterial occlusion than those currently employed, especially of heavily calcified arteries. A thermosensitive polymer, LeGoo (LG) (Pluromed, Woburn, MA), has been used successfully for temporary vascular occlusion.…
Electron density measurement remains indispensable to control fueling on a DEMO reactor. For steady-state operation of the DEMO reactor, density measurement should be highly reliable and accurate. A dispersion interferometer and a Faraday polarimeter are free from measurement errors caused by mechanical vibrations. He…
Laser irradiation, using a continuous wave CO2 crosscurrent laser with generated beam power of 1 kW, was performed on an adamite steel and an indefinite chilled cast iron roll materials which were used in the industries. Optical microscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (E…
We report the use of a pre-heated catalytic filter to improve the stability and cross sensitivity of metal oxide gas sensors (MOS). For characterization a pure and gold coated Al2O3 foamed ceramic is integrated into a newly designed chamber. When heating up the foamed ceramic, the Pd/SnO2 sensor shows a significant se…
Nonlinear dielectric response of diglycine nitrate (DGN) crystal was investigated via measurements of linear, nonlinear dielectric susceptibilities and ferroelectric hysteresis loops. The behaviour of the third order susceptibility agrees with predictions of the thermodynamic theory of the continuous ferroelectric pha…
Pure and Au incorporated WO3 thin films have been investigated for their sensing properties towards CO. Pure WO3 sensor film exhibited an increase in resistance while Au: WO3 films showed opposite behavior i.e. a decrease in resistance. We propose mechanism(s) for this anomalous sensing behavior of CO.
The electrical performance of arcing electrical contacts in AC and DC switching devices depends not only on the switch design and contact material but also on the quality of the attachment of the contact component to the support carrier. Various attachment methods such as welding and brazing lead to different characte…
Application of LaGaO3 based electrolyte for steam electrolysis at intermediate temperature was studied for the generation of hydrogen and oxygen by using the unused heat energy from steelmaking process. It was found that H2 formation rate was much improved by combination of oxygen ion conducting oxide with NiFe (9:1)…
At a location in the central mountain area of the Chugoku region (Bihoku area), concentrations of 131I, 137Cs and 134Cs in rain and air dust were measured before and after the Tohoku-Pacific Ocean Earthquake that occurred on 11 March 2011. Rainwater was also sampled at a location near the Inland Sea. The rainwater was…
Powders are well known for their dispersive properties, which derive from the many dissipative processes that occur during densification.While numerous studies have been devoted to understand these processes over a wide range of initial densities, the influence of particle morphology has been for the large part overlo…
Global hysteretic properties of electrical steels can be measured using ring or strip samples, while the assessment of the local hysteretic properties is a much more difficult task since the measurement method needs to be very sensitive. This paper presents a new method wherein the intensity and spatial distribution o…
This paper presents dynamic modeling of Ionic Polymer Metal Composites (IPMC) using passive electric network components. The dynamic model using standard electric network components is a novel approach to model the transient and steady state voltage and current characteristics of IPMCs. This leads to a global model fo…
To analyse the effect on electronic structure of nitrogen-doped graphene nanoribbons, the parameters such as the lattice, band structure, density of states of intrinsic graphene nanoribbon, N-doped graphene nanoribbons are calculated by using first-principle method. The results demonstrate that the band gap of graphen…
