Determination of Vitamin E in Canola Seeds by High Performance Liquid Chromatography
(Asian Journal Of Chemistry, 2012)
Tocopherols (vitamin E) are natural phenolic antioxidants present in vegetable oils and are responsible for many healthful properties of these foods. They are effective radical scavengers and defend the body against free ...
Determination of Ascorbic Acid in Common Fruits, Herbal Tea by Using Cuprac and Cerac Methods
(Asian Journal Of Chemistry, 2012)
The method used to determine the ascorbic acid (Vitamin C) is based on the oxidation of ascorbic acid to dehlydroascorbic acid with the cupric ion reducing antioxidant capacity (CUPRAC) and ceric-reducing antioxidant ...
Excess Capacitance Due to Minority Carrier Injection in CrSi2/p-Type Crystalline Si Isotype Junction
(Iop Publishing Ltd, 2010)
Excess current and capacitance phenonema were observed for the first time on a CrSi2/p-type crystalline silicon junction produced by cathodic arc physical vapor deposition. The heterojunction was investigated by ...
Characterization of vibrational and mechanical properties of quaternary compounds Cu2ZnSnS4 and Cu2ZnSnSe4 in kesterite and stannite structures
(Amer Physical Soc, 2011)
In this paper, structural, elastic, and dynamical properties of Cu2ZnSnS4 and Cu2ZnSnSe4 are calculated for kesterite and stannite structures using the density functional and density functional perturbation theories. The ...
Cylindrically symmetric vacuum solutions in higher dimensional Brans-Dicke theory
(Amer Inst Physics, 2010)
Higher dimensional, static, cylindrically symmetric vacuum solutions with and without a cosmological constant in the Brans-Dicke theory are presented. We show that for a negative cosmological constant and for specific ...
Two-Dimensional Fringe Projection for Three-Dimensional Shape Measurements by Using the CWT Phase Gradient Method
(Springer, 2011)
This paper describes an optical measurement technique for the two-dimensional fringe pattern (by introducing the carrier frequencies in two spatial directions x and y) by the continuous wavelet transform (CWT) phase gradient ...
Spectral properties of LiFeAs: An LDA plus DMFT study
(Maik Nauka/Interperiodica/Springer, 2012)
Spectral properties of LiFeAs superconductor are investigated within the LDA+DMFT method. Calculated distribution of the spectral weight in the k-space is in good agreement with angle-resolved photoemission (ARPES) spectra. ...
Effect of (Mo, W) substitution for Nb on glass forming ability and magnetic properties of Fe-Co-based bulk amorphous alloys fabricated by centrifugal casting
(Elsevier Science Sa, 2011)
In this study, effects of simultaneous Mo and W substitution for Nb additions on the stability and magnetic properties of Fe-Co-based bulk metallic glass (BMG) alloys fabricated by centrifugal casting are investigated. The ...
Growth, Electrical, and Optical Study of ZnS:Mn Thin Films
(Polish Acad Sciences Inst Physics, 2012)
In this study, ZnS and Mn-incorporated (at 2%, 4%, and 6%) ZnS films were deposited onto glass substrates by ultrasonic spray pyrolysis technique, and the effect of Mn incorporation on the electrical and optical properties ...
Effect of Thickness on Magnetic Properties of Fe36Co36B19.2Si4.8Mo2W2 Thin Film Prepared by Thermionic Vacuum Arc
(Polish Acad Sciences Inst Physics, 2012)
Fe36Co36B19.2Si4.8Mo2W2 amorphous thin films have been produced by thermionic vacuum arc with thickness varying from 200 nm to 260 mn. X-ray diffraction has been employed to reveal a predominant amorphous phase in the ...
