We report the systematic studies on the fabrication of aligned, uniform, and highly dense diamond nanostructures from diamond films of various granular structures. Self-assembled Au nanodots are used as a mask in the self-biased reactive-ion etching (RIE) process, using an O2/CF4 process plasma. The morphology of diamond nanostructures is a close function of the initial phase composition of dia...

not all values of literary texts should be sought for in their artistic aspects . there have been many lower-ranked literary texts that have shed light on numerous scientific, historical, social, and cultural issues. although poetic views are involved while raising such issues, it needs to be taken into account that not all poets have perceived the scientific principles of the topics tackled in...

background: the purpose of this study was to evaluate the dependency of magica polymer gel dosimeter response (r2) on different electron energies as well as on different mean dose rate for a standard clinically used linear accelerator. materials and methods: the sensitivity of the dosimeter was represented by the slope of calibration curve in the linear region measured for each modality. a cali...

in radiation cancer treatments, the most of the side effects could be minimized using a proper dosimeter. gel dosimeter is the only three‑dimensional dosimeter and magnetic resonance imaging (mri) is the gold standard method for gel dosimeter readout. because of hard accessibility and high cost of sample reading by mri systems, some other alternative methods were developed. the optical computed...

Background: An effective polymer gel dosimeter can be fabricated by varying the composition of its chemical components. Materials and Methods: The MAGAT gel dosimeter formulations that used different compositions of Methacrylic acid (MAA) and gelatin were extensively investigated in the present study according to the R2–dose response and R2–dose sensitivity. The irradiation of M...

The widespread diffusion of precision radiotherapy techniques, geared toward the release larger dose gradients in shorter time frames, is leading to new challenges dosimetry. Accurate measurements are essential check for beam anomalies and inaccuracies ensure treatment efficacy patient safety during radiotherapy. This work describes main features a diamond dosimeter coupled an extremely compact...
