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 ...
Encapsulation of polyphenolic antioxidants from medicinal plant extracts in alginate-chitosan system enhanced with ascorbic acid by electrostatic extrusion
(Elsevier, Amsterdam, 2011)
In this study the encapsulation of raspberry leaf, hawthorn, ground ivy, yarrow, nettle and olive leaf extracts was performed by electrostatic extrusion in alginate-chitosan microbeads, with ascorbic acid being used for ...
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 ...
Improvement of chemical control in the water-steam cycle of thermal power plants
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
A more effective chemical control in the water-steam cycle (WSC) of thermal power plants (TPP) is proposed in this paper. Minimization of corrosion effects by the production of ultra pure water and its strict control is ...
Viscosity of the binary systems 2-methyl-2-propanol with n-alkanes at T=(303.15, 308.15, 313.15, 318.15 and 323.15)K: Prediction and correlation - New UNIFAC-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2010)
Viscosities for the binary mixtures 2-methyl-2-propanol + n-heptane, +n-octane, +n-nonane and +n-decane have been measured at 303.15, 308.15, 313.15, 318.15 and 323.15 K and atmospheric pressure. Viscosity deviations for ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
CdSe/CdS nanoparticles immobilized on pNIPAm-based microspheres
(Royal Soc Chemistry, Cambridge, 2010)
In this work, CdSe/CdS semiconductor ligand-exchanged nanoparticles have been immobilized on poly-(N-isopropylacrylamide) (pNIPAM)-based microspheres. The size and the shrinkage capacity of the spheres can be tuned by the ...
Functionalization of cotton fabrics with corona/air RF plasma and colloidal TiO2 nanoparticles
(Springer, Dordrecht, 2011)
This study discusses the possibility of using a corona discharge at atmospheric pressure and air RF plasma at low pressure for the cotton fibre activation prior to deposition of colloidal TiO2 nanoparticles in order to ...
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. ...
