Background: In this study the basic radiation properties of N-isopropylacrylamaide polymer gel dosimeter were determined together with verification of its soft tissue equivalency. Materials and Methods: The NIPAM gel was prepared and irradiated approximately 2 h after manufacturing. The magnetic resonance (MR) images were made 24 h after irradiation. The nuclear magnetic resonance (NMR) respons...

sulfated titania nanoparticles (so42-/tio2 nps) were synthesized using titanium tetraisopropoxide (ttip) by the sol-gel method. the structure and morphology of the prepared nanocatalyst was characterized using x-ray diffraction (xrd), scanning electron microscopy (sem) and brunauer–emmett–teller (bet) methods as well as fourier transform infrared (ft-ir) and energy dispersive x-ray (edx) spectr...

tio2 nanorods are synthesized by a thermal corrosion. in present work, synthesis of tio2 nanorods in anatase, rutile and ti8o15 phases, by using the sol-gel method and alkaline corrosion are reported. the morphologies and crystal structures of tio2 nanorods are characterized by use of field emission scanning electron microscopy, atomic force microscopy and x-ray diffractometer techniques. the o...

aim: to investigate the effect of emdogain gel (emd) in pulpotomized primary molars and its clinical and radiographic outcomes. methods and materials: in this   study, 18 lower second primary molars of nine children were treated by   pulpotomy. the teeth were randomly assigned to the emd (experimental) and formocresol (control) groups in each patient (split mouth). following removal of the coro...

calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. the average crystallite size of the prepared ferrite was in the order of ~70- 92 ...

parameters that have to be measured in gel dosimetry. however, the resolution in gel is strongly dependant on gel composition. selection of optimum method in dose response readout and proper values of parameters can result in noise reduction as well as improvement of contrast, and spatial resolution considerably. materials and methods: magica polymer gel dosimeters were manufactured and irradia...
