Photopolymerized poly(Ethylene glycol) diacrylate hydrogels for controlled release of ketoprofen
(2009)
In this study, poly(ethylene glycol-diacrylate) (PEG-DA) hydrogels with two different concentrations, 30% and 50% w/w, were prepared by free radical polymerization method. Ethylene glycol dimethacrylate (EGDMA) and ...
Adsorption of a textile dye onto activated sepiolite
(Elsevier, 2009)
Adsorption of Remazol red B (RRB) on thermal activated sepiolite (TAS) and acid activated sepiolite (AAS) from aqueous solutions was investigated at different parameters, such as, adsorbent type, temperature, contact time ...
Adsorption kinetics of maxilon yellow 4GL and maxilon red GRL dyes on kaolinite
(Elsevier Science Bv, 2009)
Kaolinite, a low-costly material, is the most abundant phyllosilicate mineral in highly weathered soils. in this work, the adsorption kinetics of maxilon yellow 4GL (MY 4GL) and maxilon red GRL (MR GRL) dyes on kaolinite ...

Introduction - The phytochemical and biological studies carried out on Salvia species showed that their extracts and constituents have various biological activities. Objective - The aim of this study was the isolation of ...
Adsorption of Cu(II) onto silica gel-immobilized Schiff base derivative
(Elsevier, 2009)
4-chloroisonitroacetophenone 4-aminobenzylhydrazone (CAAH) chemically anchored on a silica gel surface, has been used for Cu(II) sorption from aqueous solution. The surface modification processes was performed after ...
Plasma treatment of polypropylene fabric for improved dyeability with soluble textile dyestuff
(Elsevier, 2009)
The impact of plasma treatment parameters on the surface morphology, physical-chemical, and dyeing properties of polypropylene (PP) using anionic and cationic dyestuffs were investigated in this study. Argon plasma treatment ...
Antioxidant and Anticholinesterase Activity Evaluation of ent-Kaurane Diterpenoids from Sideritis arguta
(Amer Chemical Soc, 2009)
The petroleum ether and acetone extracts of the aerial parts of Sideritis arguta afforded two new and six known diterpenoids with the ent-kaurane skeleton. The structures of the new diterpenoids were determined as ent-7 ...
Double-walled carbon nanotube based carbon paste electrode as xanthine biosensor
(Springer Wien, 2009)
We describe the first usage of a double walled carbon nanotube (DWCNT) modified carbon paste electrode as biosensor transducer. Xanthine was chosen as a substrate for evaluation of the electrode performance. Proper amount ...
Removal of cationic dyes by kaolinite
(Elsevier Science Bv, 2009)
The removal of cationic dyes such as maxilon yellow 4GL (MY 4GL) and maxilon red GIRL (MR GRL) on kaolinite from aqueous solutions has been studied according to the adsorption method. The adsorbed amount of dyes on kaolinite ...
