Application of well-defined ruthenium alkylidenes to the ROMP of norbornene derivatives: Methoxyphenyl-substituted polynorbornene dicarboximides
(Elsevier Science Bv, 2011)
The applicability of ruthenium alkylidenes as initiators in the ring opening metathesis polymerization (ROMP) of methoxyphenyl group containing norbornene derivatives has been investigated. The synthesis and polymerization ...
Ca-alginate as a support for Pb(II) and Zn(II) biosorption with immobilized Phanerochaete chrysosporium
(Elsevier Sci Ltd, 2003)
The basidio spores of Phanerochaete chryosporium were immobilized in alginate gel beads, and the immobilized spore containing alginate beads were incubated for the growth of fungus. The biosorption of Pb2+ and Zn2+ ions ...
Immobilization of a- amylase on reactive modified fiber and its application for continuous starch hydrolysis in a packed bed bioreactor
(Wiley-V C H Verlag Gmbh, 2014)
In this study, the enzyme -amylase was immobilized on reactive modified poly (ethylene terephthalate) fiber. The activities of free -amylase and immobilized -amylase were compared in a batch starch hydrolysis system. Optimum ...
One step effective removal of Congo Red in chitosan nanoparticles by encapsulation
(Pergamon-Elsevier Science Ltd, 2017)
Chitosan nanoparticles (CNPs) were prepared with ionotropic gelation between chitosan and tripolyphosphate for the removal of Congo Red. The production of chitosan nanoparticles and the dye removal process was carried out ...
Kinetic study of ligand exchange reaction of anions as ligands on DAE-sporopollenin
(Academic Press Inc Jnl-Comp Subscriptions, 1996)
The specific rate coefficients and ligand sorption isotherms of Br and I- as ligands on diaminoethyl-sporopollenin were determined as a function of pH and temperature between 20 and 60 degrees C. The ligand exchange rates ...
Removal of chromium(VI) from aqueous solutions using poly(4-vinyl pyridine) beads
(Wiley, 2006)
Sorption of hexavalent chromium ions from aqueous solution by poly 4-vinyl pyridine [Poly(4-VP)] was studied. The batch method was applied for adsorption processes. The effects of initial ion concentration, time, pH and ...
Effective Degradation of 2,4,6-Trinitrotoluene (TNT) with a Bacterial Consortium Developed from High TNT-degrading Bacteria Isolated from TNT-contaminated Soil
(2018)
In this study, bacterial strains, capable of using TNT as a nitrogen source, were isolated from TNT-contaminated soil samples collected from military region in Kırıkkale, Turkey. We selected three strains that showed the ...
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)
We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ...
Fibrous polymer-grafted chitosan/clay composite beads as a carrier for immobilization of papain and its usability for mercury elimination
(Springer, 2016)
Papain, which is an industrially important enzyme, has been immobilized on fibrous polymer-modified composite beads, namely poly(methacrylic acid)-grafted chitosan/clay. Characterization studies have been done using FTIR ...
Graft copolymerization of n-vinyl-2-pyrrolidone on dimethyl sulfoxide pretreated poly(ethylene terephthalate) films using azobisisobutyronitrile initiator
(John Wiley & Sons Inc, 1997)
Poly(ethylene terephthalate) (PET) films were grafted with n-vinyl-2-pyrrolidone (n-VP) using an azobisisobutyronitrile (AIBN) initiator. Films were pretreated in dimethyl sulfoxide (DMSO) for 1 h at 140 degrees C before ...
