Thermal stability and frequency-dependent electrical conductivity of poly(aniline-co-m-nitroaniline)
(
Institute for Ionics
, 2019 , Article)
Herein, we report the frequency-dependent AC conductivity of poly(aniline-co-m-nitroaniline)s which were synthesized by chemical oxidation of aniline and m-nitroaniline using ammonium persulfate as an oxidizing agent by ...
Evaluation of thermal history and defect in friction stir processing of as-cast magnesium AZ91
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Friction stir processing (FSP) is a thermos-mechanical process for modifying the microstructural and material properties of metals. FSP also can be used for mechanical alloying and producing metal matrix composites. Due ...
Investigating Determinants of Student Satisfaction in the First Year of College in a Public University in the State of Qatar
(
Hindawi Limited
, 2018 , Article)
Purpose. A first-year student's life is a web of interrelated academic and social experiences. Most universities have rigorous processes to achieve excellence or reach high-quality standards, with "Student Satisfaction" ...
Investigation of the Effect of Larestan's Pipeline Water on the Mechanical Properties of Concretes Containing Granite Aggregates
(
Hindawi Limited
, 2019 , Article)
In this study, the compressive strength of the concretes made by the pipeline water of Larestan has been investigated. Although the used water for the concretes must be clean, standard, and generally drinkable water, in ...
Strain gradient based dynamic response analysis of heterogeneous cylindrical microshells with porosities under a moving load
(
Institute of Physics Publishing
, 2019 , Article)
Forced vibration of a porous functionally graded (FG) cylindrical microshell due to a moving point load with constant velocity is studied for the first time. Through the thickness of microshell, there are even-type or ...
Highly improved AC conductivity of poly(aniline-o-fluoroaniline)
(
Institute for Ionics
, 2019 , Article)
An improved frequency dependent AC-conductivity ng of poly(aniline-co-o-fluoroaniline)s (PA-co-o-FAs) has been recorded which are synthesized by in-situ copolymerization of aniline with o-fluoroaniline by oxidation of the ...
Resonator based switching technique between ultra wide band (Uwb) and single/dual continuously tunable-notch behaviors in uwb radar for wireless vital signs monitoring
(
MDPI AG
, 2018 , Article)
This paper presents a novel resonator that can switch and create three important behaviors within the same antenna using miniaturized capacitors. The resonator was integrated into conventional Ultra-Wide Band (UWB) antenna ...
Electrochemical, morphological, and spectroscopic study of poly(aniline-co-o-bromoaniline) (PA-co-o-BrA) conducting copolymer
(
Institute for Ionics
, 2018 , Article)
A series of moderately conducting and soluble copolymers of poly(aniline-co-o-bromoaniline) (PA-co-o-BrA) having different compositions was obtained by in the situ copolymerization method using different concentrations of ...
Post-buckling analysis of piezo-magnetic nanobeams with geometrical imperfection and different piezoelectric contents
(
Springer Verlag
, 2019 , Article)
Thermal post-buckling behavior of a geometrically imperfect/perfect piezo-magnetic nano-scale beams made of two-phase composites is analyzed in the present paper based on nonlocal elasticity theory. For the first time, the ...
Investigation of the temperature-relatedwear performance of hard nanostructured coatings deposited on a s600 high speed steel
(
MDPI AG
, 2019 , Article)
Thin hard coatings are widely known as key elements in many industrial fields, from equipment for metal machining to dental implants and orthopedic prosthesis. When it comes to machining and cutting tools, thin hard coatings ...
