چکیده

A single-step, self-contained method for determining the crystallite-size distribution and shape from experimental x-ray line profile data is presented. It is shown that the crystallite-size distribution can be determined without invoking a functional form for the size distribution, determining instead the size distribution with the least assumptions by applying the Bayesian/MaxEnt method. The Bayesian/MaxEnt method is tested using both simulated and experimental CeO2 data, the results comparing favourably with experimental CeO2 data from TEM measurements.

Bayesian Analysis of Ceria Nanoparticles from Line Profile Data

A Bayesian/Maximum entropy (MaxEnt) method is applied to quantify the broadening of Xray line profiles in terms of the nanocrystallite size effects in ceria. The analysis is in general agreement with transmission electron microscopy results, while demonstrating the importance of appropriate a priori information needed in the method. The analysis also identifies other microstructural effects, su...

CHANDRA DETECTION OF DOPPLER SHIFTED X-RAY LINE PROFILES FROM THE WIND OF ζ PUPPIS (O4f)

We report on a 67 ks HETG observation of the optically brightest early O-star, ζ Pup (O4 f). Many resolved X-ray lines are seen in the spectra over a wavelength range of 5 to 25 Å. Chandra has sufficient spectral resolution to study the velocity structure of isolated X-ray line profiles, and to distinguish the individual forbidden, intercombination, and resonance (fir) emission lines in several...

Implementation of Traditional (S-R)-Based PM Method with Bayesian Inference

In order to perform Preventive Maintenance (PM), two approaches have evolved in the literature. The traditional approach is based on the use of statistical and reliability analysis of equipment failure. Under statistical-reliability (S-R)-based PM, the objective of achieving the minimum total cost is pursued by establishing fixed PM intervals, which are statistically optimal, at which to replac...

Radiosensitization effect of ZnO nanoparticles in lung cancer cells at clinically relevant megavoltage energy

Introduction: Radiation therapy is one of the major modalities that have long been used in cancer treatment. Radiotherapy is often accompanied by early and late toxicity and side effects and narrow therapeutic window. Similarity in radiation absorption properties of tumors and neighboring healthy tissues is often the reason for low specificity of radiation therapy. Development ...
