Dichromate and phosphate sorption capacity of bis formyl calix[4]arene on superparamagnetic iron oxide nanoparticles in aqueous phase
(Chemical Publishing Co., 2016)
Calix[4]arene derivatives were added into aqueous phase phosphate and dichromate solutions in order to investigate sorption capacity at pH of 1.5 to 5.5. A 25 mg of polymers magnetic calix[4]arenes derivatives was added ...
Degradation of poly(vinyl chloride) onto KF-Al 2O 3
(2010)
g-Alumina coated with potassium fluoride, KF-Al 2O 3 proved dehydrochlorination of poly(vinyl chloride), in tetrahydrofuran. The molecular changes was observed in the accurance of polyene sequence distribution by using ...
Preparation of a new polymer-dispersed liquid crystal film by using phthalocyanine-functional photocurable copolymer
(John Wiley and Sons Inc., 2015)
A new, asymmetrical zinc phthalocyanine (aZnPc)-functional photocurable copolymer was prepared by the combination of atom transfer radical polymerization and copper (I)-catalyzed azide-alkyne cyclo-addition (CuAAC) click ...
Effect of attachment types and number of implants supporting mandibular overdentures on stress distribution: A computed tomography-based 3D finite element analysis
(Elsevier Ltd, 2015)
The objective of this study was to calculate stresses in bone tissue surrounding uncoupled and splinted implants that are induced by a bite force applied to the mandible and to determine whether the number of mandibular ...
Preparation and characterization of pH responsive poly(methacrylic acid-acrylamide-N-hydroxyethyl acrylamide) hydrogels for drug delivery systems
(John Wiley and Sons Inc., 2016)
In this study, pH responsive polymers composed of methacrylic acid, acrylamide, and N-hydroxyethyl acrylamide were synthesized by free radical polymerization technique. The characterization was done with Fourier transform ...
Wideband long wave infrared metamaterial absorbers based on silicon nitride
(American Institute of Physics Inc., 2016)
In this paper, we present silicon nitride metamaterial absorber designs that accomplish large bandwidth and high absorption in the long wave infrared (LWIR) region. These designs are based on the metal-insulator-metal ...
Changes in hydrolysable and condensed tannins of pomegranate (Punica granatum L., cv. Hicaznar) juices from sacs and whole fruits during production and their relation with antioxidant activity
(Academic Press, 2014)
The effects of clarification and pasteurization on hydrolysable tannins (HTs), condensed tannins (CTs) and antioxidant activities of pomegranate juices extracted from whole fruits and sacs were investigated. Tannin contents ...
