Microstructure evolution and mechanical properties of twinned AZ31 alloy plates at lower elevated temperature
(
Elsevier Ltd
, 2014 , Article)
The AZ31 alloy plates were pre-rolled at room temperature along the transverse direction to introduce extension twinning. The effect of pre-existing twins on the mechanical properties of AZ31 alloy plates at lower elevated ...
A market basket survey of As, Zn and Se in rice imports in Qatar: Health implications
(
Elsevier
, 2014 , Article)
Qatar is dependent on importation of rice, its staple dish, and is therefore susceptible to compromises of food quality in the global market. This market basket study assesses potential health risks of As exposure from ...
Improved mechanical and corrosion properties of nickel composite coatings by incorporation of layered silicates
(
Elsevier B.V.
, 2014 , Article)
Layered silicates as exfoliated montmorillonite are incorporated into nickel films by electrodeposition, enhancing both corrosion resistance and hardness. Films were deposited onto stainless steel from a plating solution ...
Rheology of a viscoelastic zwitterionic surfactant used in acid stimulation: Effects of surfactant and electrolyte concentration
(
Elsevier
, 2014 , Article)
Acid diversion systems play an important role in increasing the efficiency of the acid stimulation process. Viscoelastic surfactant (VES) based diverting systems have many advantages that make them preferred for well acid ...
Novel deformation structures of pure titanium induced by room temperature equal channel angular pressing
(
Elsevier B.V.
, 2014 , Article)
Novel deformation structures of commercial pure (CP) Ti induced by equal channel angular pressing (ECAP) at room temperature have been studied by electron backscattering diffraction (EBSD). All the deformation twins occurring ...
"Protecting" or "policing": Academic researchers' view of IRBs in an arab context
(
SAGE Publications Inc.
, 2014 , Article)
A recent surge of research universities and human subjects research funding in the Arab world raises concerns about applied research ethics and oversight. In-depth interviews conducted with 52 researchers in Lebanon and ...
Improved mechanical properties of AZ31 magnesium alloy plates by pre-rolling followed by warm compression
(
Elsevier Ltd
, 2014 , Article)
AZ31 magnesium alloy plates were processed by pre-rolling followed by warm compression. The corresponding microstructure evolution and mechanical properties were investigated in the present paper. The pre-introduced twins ...
Synthesis and electrochemical properties of nickel oxide/carbon nanofiber composites
(
Elsevier Ltd
, 2014 , Article)
The electrospinning of polyacrylonitrile (PAN) with a polyaniline and graphene sol–gel mixture produced uniform, smooth fibers with an average diameter of 0.3 μm. These electrospun fibers were stabilized for 2 h at 200 °C ...
Salinity inhibits seed germination of perennial halophytes Limonium stocksii and Suaeda fruticosa by reducing water uptake and ascorbate dependent antioxidant system
(
Elsevier B.V.
, 2014 , Article)
Information about production and detoxification of reactive oxygen species during seed germination of halophytes under saline conditions is scanty. We therefore studied levels of common oxidative stress markers, antioxidant ...
Quadrupolar benzobisthiazole-cored arylamines as highly efficient two-photon absorbing fluorophores
(
American Chemical Society
, 2014 , Article)
A computer-aided design of novel D-?-A-?-D styrylamines containing five isomeric benzobisthiazole moieties as the electron-accepting core has revealed the linear centrosymmetric benzo[1,2-d:4,5-d?]bisthiazole as the most ...
