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 ...
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 ...
Optimization of selection of chain amine scrubbers for CO2 capture
(
Springer Verlag
, 2014 , Article)
In order to optimize the selection of a suitable amine molecule for CO2 scrubbers, a series of ab initio calculations were performed at the B3LYP/6-31+G(d,p) level of theory. Diethylenetriamine was used as a simple chain ...
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 ...
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 ...
Electrodeposition of nanostructured Nickel-Ceramic composite coatings: A review
(
Electrochemical Science Group
, 2014 , Article)
This review presents a recent literature on electrochemically prepared nickel-ceramic nanocomposites coatings. These nanostructured coatings exhibit remarkable enhanced corrosion resistance and microhardness which are of ...
Concentration, composition and sources of PAHs in the coastal sediments of the exclusive economic zone (EEZ) of Qatar, Arabian Gulf
(
Elsevier Ltd
, 2014 , Article)
Surface sediments were collected from sixteen locations in order to assess levels and sources of polycyclic aromatic hydrocarbons (PAHs) in sediments of Qatar exclusive economic zone (EEZ). Samples were analyzed for 16 ...
Surface Behavior of Polyamide 6 Modified by Barrier Plasma in Oxygen and Nitrogen
(
Taylor & Francis
, 2014 , Article)
Polyamide (PA) 6 was modified by diffuse coplanar surface barrier discharge (DCSBD) plasma in an atmosphere of nitrogen and oxygen. The surface roughness decrease of PA 6 was detected by AFM and nano-indentation after ...
Cryogenic temperature and strain rate dependence of mechanical properties for extruded AA6060 alloys
(
Trans Tech Publications Ltd
, 2014 , Article)
Tensile properties and fracture behavior of an AA6060 alloy were investigated at room temperature (295K) and cryogenic temperature (77K). It was found that both ultimate tensile strength and elongation increased with ...
Thermal properties measurement and heat storage analysis of paraffin/graphite composite phase change material
(
Elsevier Ltd
, 2014 , Article)
This study aims at the preparation of a paraffin/graphite waste composite for thermal energy storage application at low temperature. In this composite material, the paraffin is characterized by high phase change latent ...
