New formula for Calculation of Cobalt-60 Percent Depth Dose
Introduction: On the basis of percent depth dose (PDD) calculation, the application of dosimetry in radiotherapy has an important role to play in reducing the chance of tumor recurrence. The aim of this study is to introduce a new formula for calculating the centeral axis percent depth doses of Cobalt-60 beam. Materials and Methods: In the present study, based on ...
متن کاملVapor Pressures of Platinum , Iridium , and Rhodium
Systematic measurements of the vapor pressure of iridium and rhodium over a wide temperatme range have not been published previously. A summary of previous estimates or observations of their normal boiling points and values of their heats of sublimation, f:..H ~ (298), is given in table l. The vapor pressure of platinum was calculated by Langmuir and .Mackay from measurements of the rate of sub...
متن کاملRhodium and iridium complexes with a new scorpionate phosphane ligand.
A straightforward synthesis of a new hybrid scorpionate ligand [(allyl)2B(CH2PPh2)(Pz)](-) ([A2BPN](-)) is reported. Coordination to rhodium resulted in square-planar complexes [Rh(κ(2)-A2BPN)(L)(L')] [L = L' = (1)/2cod (1,5-cyclooctadiene), CN(t)Bu, CO (6); L = CO, L' = NH3, pyridine, PPh3, PMe3] for which spectroscopic data and the molecular structure of [Rh(κ(2)-A2BPN)(CO)PPh3] (11) indicate...
متن کاملPicosecond time-resolved infrared spectroscopy of rhodium and iridium azides.
Picosecond time-resolved infrared spectroscopy was used to elucidate early photochemical processes in the diazido complexes M(Cp*)(N3)2(PPh3), M = Rh (), Ir (), using 266 nm and 400 nm excitation in THF, CH2Cl2, MeCN and toluene solutions. The time-resolved data have been interpreted with the aid of DFT calculations on vibrational spectra of the singlet ground states and triplet excited states ...
