Embodied water for urban economy: A three-scale input-output analysis for Beijing 2010
(
Elsevier
, 2015 , Article)
The scheme of a three-scale input-output analysis is presented in this study to investigate the water use profile of the urban economy in Beijing. Defined as total water including direct and indirect water, embodied water ...
Graphene and graphitic derivative filled polymer composites as potential sensors
(
Royal Society of Chemistry
, 2015 , Article)
Graphite and numerous graphitic-derived micro- and nano-particles have gained importance in current materials science research. These two-dimensional sheets of sp2-hybridized carbon atoms remarkably influence the properties ...
Free-volume correlation with mechanical and dielectric properties of natural rubber/multi walled carbon nanotubes composites
(
Elsevier Ltd
, 2015 , Article)
Abstract The microstructure, mechanical strength, dielectric properties, Doppler broadening measurements and positron life time studies of the composites containing multi walled carbon nanotubes (MWCNTs) and natural rubber ...
Enhanced morphology and mechanical characteristics of clay/styrene butadiene rubber nanocomposites
(
Elsevier Ltd
, 2015 , Article)
Achieving complete exfoliation of clay in their polymer nanocomposite is a matter of interest as it can significantly affect the material properties. Herein, an efficient way of enhancing the interlayer spaces of organically ...
Kinetics and thermodynamics of enhanced adsorption of the dye AR 18 using activated carbons prepared from walnut and poplar woods
(
Elsevier
, 2015 , Article)
Activated carbons prepared from walnut and poplar woods are used as economical adsorbents for the rapid removal and fast adsorption of Acid Red 18 dye from the aqueous solutions; the kinetics, isotherm and thermodynamics ...
Metal distribution in marine sediment along the Doha Bay, Qatar
(
Kluwer Academic Publishers
, 2015 , Article)
Concentrations of 25 heavy metals (Ag, Al, As, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, V, Zn and Hg) in surface sediments along the Doha Bay from 10 transects each with five stations were ...
Selective removal of dibenzothiophene from commercial diesel using manganese dioxide-modified activated carbon: A kinetic study
(
Taylor and Francis Ltd.
, 2015 , Article)
With a total concentration of 7055 mgS/kgfuel, the content of organosulphur compounds (OSCs) in local diesel is 20 times higher than the regulated value. Analysis revealed that 30% of OSC is originated from dibenzothiophene ...
Influence of diesel acidification on dibenzothiophene removal: A new desulfurization practice
(
Elsevier
, 2015 , Article)
Commercial diesel is often loaded with organosulphur compounds including hard-to-remove dibenzothiophene DBT and other derivatives. Following uncommon and simple procedure, dibenzothiophene was selectively removed upon ...
A novel desulfurization practice based on diesel acidification prior to activated carbon adsorption
(
Springer New York LLC
, 2015 , Article)
Commercial diesel is often rich with organosulfur compounds and a value of 7,100 mgS/kg was recently reported. As confirmed by chromatographic analysis, about 36% of sulfur compounds are originated from dibenzothiophene. ...
Insights into the remediation characterization of modified bentonite in minimizing organosulphur compounds from diesel fuel
(
Korean Society of Industrial Engineering Chemistry
, 2015 , Article)
In this work, physical and chemical characteristics of the raw, treated, and acid activated bentonite were investigated using XRD, FTIR, scanning electron microscopy (SEM), and differential thermal analysis (DTA)/thermogravimetry ...
