Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
(
Elsevier B.V.
, 2015 , Article)
In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ...
Constitutive analysis for the quantification of hardness decay in a superlattice CrN/NbN hard-coating
(
Elsevier B.V.
, 2015 , Article)
In the present study, a constitutive analysis of the evolution of the mechanical response of a CrN/NbN superlattice coating exposed to high temperature has been performed. Parametric approaches were used to obtain a single ...
Canavan disease: an Arab scenario.
(
Elsevier Inc.
, 2015 , Article)
The autosomal recessive Canavan disease (CD) is a neurological disorder that begins in infancy. CD is caused by mutations in the gene encoding the ASPA enzyme. It has been reported with high frequency in patients with ...
Effect of waste wax and chain structure on the mechanical and physical properties of polyethylene
(
Elsevier B.V.
, 2015 , Article)
The influence of adding waste wax, produced as a by-product of the low density polyethylene manufacturing process, on the thermal and mechanical properties of three types of polyethylene (PE), high-density polyethylene ...
Encapsulation of tung oil for self-healing coatings in corrosion applications
(
American Scientific Publishers
, 2015 , Article)
Encapsulation of tung oil for use in self-healing applications using urea-formaldehyde as the shell was performed via in-situ polymerization. Microcapsules ranging from 100 to 250 μm with a shell wall thickness of 1.7–2.6 ...
Zero-bias photocurrents in highly-disordered networks of Ge and Si nanowires
(
Institute of Physics Publishing
, 2015 , Article)
Semiconducting nanowire (NW) devices have garnered attention in self-powered electronic and optoelectronic applications. This work explores and exhibits, for the first time for visible light, clear evidence of the zero-biased ...
A comparison of the redox properties of vanadia-based mixed oxides
(
American Chemical Society (ACS)
, 2015 , Article)
The thermodynamics of oxidation and reduction were investigated for a series of vanadium-containing oxides, including CeVO4, LaVO 4, ZrV2O7, Mg3(VO4) 2, CrVO4, AlVO4, and V2O 5, in the temperature range between 873 and 973 ...
Residual shear strength of fine-grained soils and soil-solid interfaces at low effective normal stresses
(
Canadian Science Publishing
, 2015 , Article)
A laboratory research program was undertaken to study the large-strain shear strength characteristics of fine-grained soils under low effective normal stresses ([1]3-7 kPa). Soils that cover a wide range of plasticity and ...
Estimating the elastic settlement of piled foundations on rock
(
American Society of Civil Engineers (ASCE)
