Single-layer electrodes (SLEs) were used instead of the conventional multi-layer electrodes for polymer electrolyte fuel cells (PEFCs). The cell consists of a polymer electrolyte membrane, catalyst layers and separators with a microchannel. Removing microporous layers and gas diffusion layers has a potential to enhanc…
In the manufacturing process of Li-Ion batteries the slot die coating of the electrodes is a crucial step, which is not fully understood yet. Especially the mechanisms creating super-elevations at the coating edges, which cause trouble in the downstream process steps, are not fully understood yet. Until now literature…
©2006-2015 Asian Research Publishing Network (ARPN).In the present work, the structural modifications of Ge-doped silica preforms due to γ-irradiation at room temperature have been investigated using Raman spectroscopy. The MCVD fabricated preforms labelled as P1 and P2 are distinguishable by the oxidation and thermal…

The inhibiting effect and adsorption behavior of N-[(4-chlorophenyl)(morpholin-4-yl)methyl]acetamide (CPMA) on mild steel in hydrochloric acid solution were studied by weight loss measurements, effect of temperature studies, potentiodynamic polarization and scanning electron microscopic techniques. The inhibitor showe…
First-principles calculations are performed to study the electronic structures and magnetic properties of nonmagnetic B-doped ZnO. We investigate the following three cases: (i) single B atom substituted at Zn site, (ii) single B atom substituted at O site, and (iii) two B atoms substituted at O sites. Both generalized…
Dutos flexíveis são estruturas utilizadas na indústria do petróleo em aplicações off-shore. O aspecto construtivo destes componentes compreende várias camadas metálicas e poliméricas, sendo que a camada mais externa (polimérica), forma uma barreira contra o ambiente marinho. Quando há o rompimento da camada polimérica…
Since compressor outlet pressure is an important property in an SOFC based hybrid plant, special attention is devoted to an innovative system able to increase this parameter with a commercial device. This in an essential approach to increase system performance (especially in case of an ejector based \ncathodic recircu…
Abstract Reduced activation ferritic–martensitic steels are intended to serve as structural materials in different blanket designs, e.g. HCLL, DCLL and WCLL. In these designs the material is supposed to be in direct contact with the flowing liquid breeder material Pb–15.7Li at an operating temperature of up to 550 °C.…

Recently, metallic nanowires have been applied in various applications such as plasmonics and nanoelectronics. To construct nanodevices using metallic nanowires, manipulation and fixation techniques of nanowires are indispensable. Here, we proposed a novel method for two-dimensional manipulation and fixation of a meta…
Temperature and particle size distributions along the flow axis in the premixed flame have been measured during silica nanoparticle formation for various mass fraction of oxygen, X_ [%]. For X_ = 26 %, the temperature along the axial position, z, was higher than the melting point of silica at 0 mm < z < 25 mm. The pri…

Free axisymmetric vibrational characteristics of layered truncated conical shells are studied. The method of collocation with Chebyshev polynomial approximation is used for solving the problem. The formulation of the problem is based on an extension of Love’s first approximation theory. The governing partial different…
Solid-liquid interfacial thermal resistance is thermal resistance defined for temperature jump at the interface between solid and liquid which have different temperatures. Solid-liquid interfacial thermal resistance is a microscopic phenomenon that of elucidation of the heat transfer mechanism is needed. Therefore, in…
This study focuses on the structural response of the part of the superstructure of a RoPax ferry that has been redesigned using composite materials. The composite superstructure is presented and subsequently compared to the existing steel design considering different loading conditions by the use of FE modelling.Resul…
To decrease human error of the pericardiocentesis, we aimed to develop the pericardiocentesis assistance device. Purposes of this paper are to design of the pericardiocentesis assistance device. We proposed the new pericardiocentesis assistance device that needle was not used. The proposed device is able to aspirateth…
Molecular dynamics simulations are conducted to investigate an influence of nanometer scale slit structures on molecular adsorption to a solid surface. Also, we investigate an effect of the molecular adsorption on the accommodation coefficient at a solid-vapor interface by changing interaction potential parameters bet…
Experimental data on manifestation of the spillover effect, when intercalation of the solid hydrogen into graphite nanofibers, are considered.
AbstractIn the framework of a description of melt pool heat transfer under severe accident conditions, we introduce a computational fluid dynamics approach for the phase change based on the phase-field method. The approach is derived using the formalism of irreversible thermodynamics and depends on a phenomenological…
