Atomic layer deposition (ALD) of aluminum oxide thin films were applied on lateral high-aspect-ratio silicon test structures. The leading front the film thickness profile is interest, since it related to kinetics and provides information for ALD process development. A deposited was characterized using energy-dispersive electron probe X-ray microanalysis (ED-EPMA) results analyzed Monte Carlo si...

The exploitation of mine waste materials as secondary resources requires in-depth mineralogical analyses, with metal deportment being particular relevance for recovery. Using a combination the Scanning Electron Microscope (SEM)-based Mineral Liberation Analyser (MLA) and Probe Micro-Analyser (EPMA) methods, lead zinc in historic Plombières site (East Belgium) was investigated. comprises four di...

We present a comparison of two different techniques: Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and wavelength-dispersive X-Ray Spectroscopy by electron probe microanalyzer (EPMA) for obtaining Mg/Ca ratios in individual foraminifera shells. The goal is to assess the use EPMA as an alternative technique analyses single foraminiferal calcite Foraminifera obtained fro...

Background and Aim: Cardiovascular diseases and medication errors are among the leading causes of morbidity and mortality around the world. Electronic prescribing and Medication Administration(ePMA) systems can prevent medication errors to some extent. This study aimed to determine the information requirements of ePMA systems. Materials and Methods: This descriptive study was conducted in Imam...

The performance of correction models used in light element EPMA is assessed, with a special emphasis on the energy dependence of the absorption correction factor. Recently Love and Scott /I/ have assessed the performance of the established correction procedures and some new models used in electron probe microanalysis ( E p U ) . They concluded that all methods are approximately equivalent in ac...

The purpose of this study was to analyze the physical properties and chemical compositions of a new experimental cement (NEC) and compare them with mineral trioxide aggregate (MTA); pH, working time, setting time, dimensional changes following setting, flow, film thickness, and chemical composition of NEC and MTA were assessed. For chemical compositions, all specimens were imaged and analyzed b...

Stability of thin boron-carbon films on silicon substrates was studied. EPMA measurements were used for the film characterization. If the background pressure in the setup was lower than 5 x 1 0 ~ Torr the oxygen content in the films did not exceed 3 at.%. The concentration of oxygen in the films increased considerably as a result of bad basic vacuum or insufficient degassing of precursor. While...

In the framework of the Fourth Generation program, the CEA studies a new concept of Sodium Fast Reactor (SFR) named ASTRID [1]. The reference fuel chosen for the reactor starting is uranium and plutonium mixed oxides. This type of fuel had been fabricated until 1999 during the PHENIX (French SFR prototype) operation. The industrial process led to homogeneous uranium /plutonium distributions in ...
