The IBA DataFurnace (NDF) is a general purpose program for analysis of IBA data. It currently includes Rutherford backscattering (RBS), elastic (non-Rutherford) backsscattering (EBS), elastic recoil detection analysis (ERDA), non-resonant nuclear reaction analysis (NRA), and particle induced X-ray emission (PIXE). Here we discuss recent developments in the advanced physics capabilities implemen...
در این طرح پس از ساخت سیستم مناسب برای ایجاد پلاسما در رژیم تخلیه تابان و تهیه نمونهها و انجام تحلیلهای سختی سنجی و pixe، طی مراحل مختلف، فرآیند نیتروژندهی در شرایط متفاوت انجام شد. پس از پایان نیتروژندهی نمونهها، تحلیلهای سختی سنجی و pixe به همراه تحلیلهای xrd,sem,gds و rbs بر روی قطعات انجام شد. نتایج به دست آمده در مورد فولادهای 304.316و 321 به وضوح افزایش سختی حداکثر 450 درصد را در ب...
Analytical techniques play a fundamental role in heritage science. Among them, Particle Induced X-ray Emission (PIXE) and Fluorescence (XRF) are widely used many laboratories for elemental composition analysis. Although they well-established, strong effort is put on their upgrade, making them suitable more applications. Over the years, at INFN-LABEC (the laboratory of nuclear environment cultur...
Ancient potteries found at Ban Muang Bua, located in northeastern Thailand, associate with Thung Kula Ronghai culture. Most of them are products used daily life and grave goods. The potsherds were examined using techniques based on X-ray spectroscopy. Elemental composition morphology analyzed proton-induced emission spectroscopy (PIXE) scanning electron microscopy coupled energy-dispersive (SEM...
Recently, environmental dust exposure has emerged as a possible risk factor for interstitial pneumonia. Inhaled silica/silicates and titanium are associated with the progression of rapidly progressive pneumoconiosis. However, relationship between inhaled elements idiopathic pulmonary fibrosis (IPF) remains unclear. In this study, we focused on IPF presenting histological usual pneumonia investi...
Background: The method of proton induced X-ray emission (PIXE) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. The sensitivity of this powerful method is in the order of ppm .The aim of this work is to analyze structural composition of 4 heavy trace elements with Z greater than 24 (Mn, Fe, Cu, Zn) in two kinds of gallstones and to...
