Broadband one way propagation via dielectric waveguides with unequal effective index
(Institute of Electrical and Electronics Engineers Inc., 2014)
We present an efficient approach for broad band one way propagation of light by parallel and unequal dielectric waveguides leading different effective phase shifts. Three dimensional numerical simulations show that 30% ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
A novel two-part interconnector for solid oxide fuel cells
(John Wiley and Sons Ltd, 2014)
A two-part interconnector is developed for solid oxide fuel cell stacks to reduce cost and to improve sealing. The novel interconnector involves a metallic core for current collection and gas distribution and a ceramic ...
Electrical conductivity and spectroscopic characterization of Blends of poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI copolymer with PVC exposed to gamma-rays
(2014)
Poly(2-chloroaniline)/polyaniline P(2ClANI)/PANI) random copolymer was synthesized in the form of nanoparticles by chemical routes. Incorporation of P(2ClANI) into PANI backbone significantly increased the solubility of ...
Quantitation of aflatoxins in walnut kernels by high-performance liquid chromatography with fluorescence detection
(Taylor and Francis Ltd., 2014)
A total of 85 walnut samples collected between October 2012 and April 2013 in different provinces of Turkey were analysed for the presence of aflatoxins (AFs). The method involved methanol–water extraction, clean-up with ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Synthesis and characterization of terminalalkynyl-substituted unsymmetrical zinc phthalocyanine conjugated with well-defined polymers
(2014)
Synthesis of unsymmetrically terminalalkynyl substituted zinc (II) phthalocyanine (ZnPc) through an efficient statistical condensation reaction with the unprotected phthalonitrile (2) is reported for the first time. Isolated ...
An approach to the usage of polyethylene terephthalate (PET) waste as roadway pavement material
(Elsevier, 2014)
This study investigates an application area for Polyethylene Terephthalate (PET) bottle waste which has become an environmental problem in recent decades as being a considerable part of the total plastic waste bulk. Two ...
Theoretical and experimental investigation of wear in internal gears
(2014)
Internal gears are commonly used in automotive and aeronautic industries as external sun gears of planetary mechanisms. Internal gears have some advantages such as low sliding velocities, low contact stresses, high contact ...
Tensile behavior of heat welded CNT network structures
(Elsevier, 2014)
In this study, a computational investigation on the mechanical properties of random carbon nanotube (CNT) networks is reported. For this purpose, atomistic models of 3-D CNT network structures are generated by an automated ...
