In this study, a sodalite nanozeolite was synthesized and characterized by X-ray diffraction (XRD) and scanning electronic microscopy (SEM). Following the morphology evolution of the sodalite nanozeolite in the SEM images illustrates the formation of the spherical particle with a size between 60 and 80 nm. Then, carbon paste electrode (CPE) was modified by sodalite nanozeolite and Ni2+ ions. Th...

The repair of craniofacial bone defects is surgically challenging due to the complex anatomical structure of the craniofacial skeleton. Current strategies for bone tissue engineering using a preformed scaffold have not resulted in the expected clinical regeneration due to difficulty in seeding cells into the deep internal space of scaffold, and the inability to inject them in minimally invasive...

abstract halwa-ardeh is a traditional food in iran and middle east countries, which is produced by crushing the dehulled sesame seeds and then mixing with a proper sweetener such as grape concentrate, date syrup, and honey. the oil content of this product is on the average of 57-65% (w/w). in this research, the effect of different levels of fat substitutes including guar gum (of 0.1, 0.15 and 0...

Titania nano particles were synthesized at carbon paste electrode by cyclic voltammetry and then it was employed for the determination of acetaminophen in phosphate buffer at pH 7.4. Carbon paste electrode with titania nano particle displayed excellent electrochemically catalytic activities by shifting the oxidation potential of acetaminophen towards the negative side. The mass transfer process...

2-amino-n-benzthioazolyl benzamide (abtb) was synthesized, characterized and used for thefabrication of a potentiometric sensor for cu2+ metal ions. the electrode exhibits linear response to cu(ii) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 m) with nernstian slope of 30 ± 1.5 mvper decade. the electrode can be used in the ph range from 2 to 9. it has a fast response time of about1...
