Separation and determination of arsenic species in water by selective exchange and hybrid resins
(Elsevier Science Bv, Amsterdam, 2011)
A simple and efficient method for separation and determination of inorganic arsenic (iAs) and organic arsenic (oAs) in drinking, natural and wastewater was developed. If arsenic is present in water prevailing forms are ...
Optimal waste heat recovery and reuse in industrial zones
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Significant energy efficiency gains in zones with concentrated activity from energy intensive industries can often be achieved by recovering and reusing waste heat between processing plants. We present a systematic approach ...
Study of factors affecting Ni2+ immobilization efficiency by temperature activated red mud
(Elsevier Science Sa, Lausanne, 2011)
The waste red mud, remaining in remarkable quantities after the digestion of bauxite ores following the Bayer process, contains number of voluble minerals with excellent sorption properties towards aqueous heavy metals. ...
Removal of lead from water by amino modified multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2011)
Pristine, oxidized, ethylenediamine, diethylenetriamine and triethylenetetramine modified multi-walled carbon nanotubes (raw-MWCNT, o-MWCNT, e-MWCNT, d-MWCNT and t-MWCNT, respectively) were employed as adsorbents in order ...
Fabrication and antibacterial properties of ZnO-alginate nanocomposites
(Elsevier Sci Ltd, Oxford, 2012)
Alginate was used as a controlled environment for the growth of ZnO nanoparticles. The formation of nanostructured particles was confirmed by a blue shift in the onset of the optical absorption with respect to bulk ZnO. ...
Global and Deep Molecular Analysis of Microbiota Signatures in Fecal Samples From Patients With Irritable Bowel Syndrome
(W B Saunders Co-Elsevier Inc, Philadelphia, 2011)
BACKGROUND & AIMS: Irritable bowel syndrome (IBS) has been associated with disruptions to the intestinal microbiota, but studies have had limited power, coverage, and depth of analysis. We aimed to define microbial populations ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier Science Sa, Lausanne, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
Electrochemical determination of glucose using polyaniline electrode modified by glucose oxidase
(Elsevier Sci Ltd, Oxford, 2011)
Polyaniline (PANI) enzyme electrode was formed by immobilisation of Glucose oxidase (GOx) via glutaraldehyde into electrochemically polymerised PANI on graphite electrode. Electrochemical polymerisation of PANI on graphite ...
Nonlinear Frequency Response Analysis of the Ferrocyanide Oxidation Kinetics. Part I. A Theoretical Analysis
(Amer Chemical Soc, Washington, 2011)
In this work, a nonlinear frequency response (NLFR) analysis was used for a first time in a theoretical study of nonlinear behavior of electrochemical (EC) ferrocyanide oxidation as a simple model reaction. Analytical ...
