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 ...
Anti-biofilm properties of Satureja hortensis L. essential oil against periodontal pathogens
(Elsevier Sci Ltd, 2009)
Essential oils of several plants are widely used in ethnomedicine for their antimicrobial and anti-inflammatory properties. However, very limited data exist on their use in connection to periodontal diseases. The aim of ...
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 ...
Parental Influences on Students' Self-Concept, Task Value Beliefs, and Achievement in Science
(Cambridge Univ Press, 2009)
The aim of this study was twofold: firstly, to investigate the grade level (elementary and middle school) and gender effect on students' motivation in science (perceived academic science self-concept and task value) and ...
Mitigation Effects of Silicon on Maize Plants Grown at High Zinc
(Taylor & Francis Inc, 2009)
The effects of exogenous silicon (Si) on key growth parameters and mineral nutrients were investigated in maize grown at high zinc (Zn). Four treatments with three replicates were investigated consisting of a control (basal ...
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 ...
Enhancement of flotation performance of oil shale cleaning by ultrasonic treatment
(Elsevier, 2009)
In this study, it was attempted to enhance the performance of flotation cleaning of oil shales by use of ultrasound. The use of an excitation effect through ultrasonication was investigated towards inorganic particles that ...
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 ...
Quantum Hall effect in a high-mobility two-dimensional electron gas on the surface of a cylinder
(Amer Physical Soc, 2009)
The quantum Hall effect is investigated in a high-mobility two-dimensional electron gas on the surface of a cylinder. This special topology leads to a spatially varying filling factor along the current path. The resulting ...
