XRD AND XAFS STUDIES OF CARBON SUPPORTED Pt-Ru ELECTROCATALYST IN A POLYMER-ELECTROLYTE-FUEL-CELL
Structures of carbon supported Pt-Ru catalyst in a polymer-electrolyte-fuel-cell (PEFC) were analyzed by X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAFS). XRD analysis identified a face-centered-cubic (fcc) alloy structure for Pt-Ru. XAFS analysis revealed that Pt and Ru atoms were, however, not randomly distributed in the Pt-Ru fcc lattice. A Pt atom was more likely surrounded ...
متن کاملDifferential diagnosis of pancreatic cystic masses with the quantitative analysis of spectral CT imaging: Initial results
Background: To retrospectively evaluate whether quantitative information derived from spectral imaging can improve the differential diagnosis of pancreatic cystic masses including pancreatic solid pseudopapillary epithelial neoplasms (SPENs), mucin- producing cysts and pseudocysts. Materials and Methods: From June 2015 to October 2017, 56 patients (22 pseudocysts, 18 mucin-producing cysts and 1...
متن کامل99mTc-MIBI SPECT/CT imaging contribution in the diagnosis of patients with hyperparathyroidism
Introduction: Hyperparathyroidism is presented with increased parathyroid hormone (PTH) secretion due to hyperfunctioning of one or more of the four parathyroid glands. Primary hyperparathyroidism (p-HPT) can be due to parathyroid adenoma, hyperplasia or carcinoma of the parathyroid gland. Secondary hyperparathyroidism (s-HPT) is usually a response to hypocalcaemia and consecut...
