Copper doped amorphous carbon composite films (a-C(Cu)) have been deposited by thermionic vacuum arc (TVA) technique, using two electron beams emitted by externally heated cathodes: applying high voltages (1-5kV) between cathodes and the two anodes (C, Cu), two bright plasma were ignited in C and Cu atoms. Chemical co…
Series and shunt mode directive composite right/left-handed (CRLH) zeroth-order resonant antennas (ZORAs) implemented in multilayer-technology (LTCC) are demonstrated experimentally. 1.
In this paper, the regulating role of CoOx on deleterious Cl- over PdO/SiO2 for CO oxidation has been thoroughly studied. By comparing the catalyst prepared from Pd(NO3)2 and PdCl2, the deleterious effect of Cl- has been confirmed. The addition of CoOx leads to the significant temperature-dependent variation of cataly…

This work provides an estimation procedure to determine the J-integral for pipes with circumferential sur- face cracks subjected to bending load for a wide range of crack geometries and material (hardening) based upon fully-plastic solutions. A summary of the methodology upon which J is derived setsthe necessary frame…
Controlling the assembly of nanobuilding blocks is one of the key issues to develop nanomaterials and nanodevices. A series of methods which aimed at the asymmetric modification of nanoparticles are developed recently , providing a novel and efficient strategy towards controlled assembly of nanoparticles. These method…
Heteropoly acids ( HPAs) solid high2proton conductors have received increasing attention over the last few years owing to their applications in fuel cells , sensors and electrochemical chromogenic devices etc. The present paper summarizes and reviews the current development in the area of the conductivities of HPAs ,…
proton nuclear magnetic resonance ( 1 H NMR) spectroscopy. The healing agent was obtained as a viscous oil. A methacrylate-type siloxane compound was purchased and also used as a photochemical healing agent. Photoreaction behaviour of the healing agents was investigated by photoirradiation with a xenon lamp. It was co…
The silk sericin (SS)/hydroxyapatite (HAP) composite was synthesized via a chemical co-precipitation method. The effect of mineralization time on the formation of composite, including growth of crystal, aggregation and assembly of nanoparticles, was investigated using X-ray diffraction (XRD), Fou- rier transform infra…
This work shows the approach used to the numerical simulation of the thermal test of a 1:2 scale model of a dual purpose cask (transportation and/or storage) for spent fuel elements from nuclear research reactors. Conservatively, the cask impact limiters are not modeled. This test is part of the requirements for the q…
In previous published literature, deviations in the mean crushing force and deformation pattern have been found between simulations with plane stress shell elements and experimental results for aluminium extrusions subjected to axial crushing. In the current study, simulations with solid and shell element models were…
Steels with elasticity limits between 650 and 680 MPa include thermomechanical steels and quenched and tempered steels. Thermomechanical steels have excellent weldability, but, nevertheless, require fillers with low diffusible H2 levels, and a rigorous control over the welding operations, due to the molten zone. Quenc…
The electronic properties and reactivity of Ag Pt. (1 ≤ x ≤ 10) nanoalloys were investigated by spin polarized calculations within the framework of density-functional theory (SP-DFT). Both the most energetically stable structures and the most reactive nanoalloys were determined through global reactivity indicators: ch…
Purpose: In this study, we exploited the potential of 64 Cu-labeled polyethylenimine (PEI) for cell trafficking and tumor imaging as compared to copper-64-pyruvaldehyde-bis(N 4 -methylthiosemicarbazone) ( 64 Cu-PTSM). Procedures: U87MG cells were labeled with both 64 Cu-PEI and 64 Cu-PTSM, and their in vivo distributi…
3 INCDIE ICPE-CA, 313 Splaiul Unirii, 030138, Bucharest, Romania A comparative study between solubilization and combustion methods used to prepare the organic solvent samples for liquid scintillation analyse is presented. The determination of tritium content in organic solvent waste generated during the operation of R…
Two series of N3 Schiff base complexes [M L 1 Cl] and 22-membered hexaazamacrocyclic complexes [ML 2 ] (M=Co 2+ , Ni 2+ , and Cu 2+ ) have been synthesised via the condensation reaction of para-nitobenzaldehyde with diethelyenetriammine to obtain [HL 1 ] where [HL 1 ]= N-[(4-nitrophenyl)methylene]-N'-(2-{[(4nitropheny…
New nanocomposite ceramic electrolytes with enhanced conductivity at low temperatures have been mechanically prepared based on Li2SO4–Fe2O3 system. Nanocomposites with filler concentrations of x = 0.1-0.5 have been studied by impedance spectroscopy and thermal analysis in the temperature range of 200–500oC. Unusual de…
This paper examines the phenomenon of water dropping on a hydrophobic surface. Dierent behaviors are examined as a function of adjusted parameters. Data is collected and compared to previously published data, focusing on the horizontal deformation of the water drop as well as its initial contact time with the surface.…
The paper analyses the effects of the type of resin on the impact characteristics in case of four composite materials randomly reinforced with E-glass chopped fibres. Therefore, four kinds of polymer resins were used to manufacture the composite materials: polyester Heliopol 8431 ATX, polyester Polylite 440-M880, and…
