Micro-PIXE investigation of bean seeds to assist micronutrient biofortification
Nuclear Instruments & Methods in Physics Research B, 2011 AbstractThis study compares the distribution and concentrations of micro- and macronutrients in different bean cultivars with the aim of optimizing the biofortification, a sustainable approach towards improving dietary quality. Micro-PIXE was used to reveal the distribution of Fe, Zn, Mn, Ca, P, S in seeds of common beans (Phaseolus vulgaris) and ...

Polymeric Membranes Doped with Halloysite Nanotubes Imaged using Proton Microbeam Microscopy [PDF]
Nanomaterials, 2023 Polymeric membranes are useful tools for water filtration processes, with their performance strongly dependent on the presence of hydrophilic dopants. In this study, polyaniline (PANI)-capped aluminosilicate (halloysite) nanotubes (HNTs) are dispersed ...

In-Air Micro-PIXE Mapping with Chemical Contrast. [PDF]
Anal ChemCurrently, chemically specific X-ray fluorescence imaging is restricted to synchrotron facilities and based on the chemical selectivity of X-ray absorption spectra. In this article, we demonstrate the capability of high-energy-resolution micro-PIXE spectroscopy to perform two-dimensional (2D) chemical state mapping of sulfur and phosphorus within ...

Fluoride Retention in Root Dentin following Surface Coating Material Application [PDF]
Journal of Functional Biomaterials, 2023 This study aimed to use an in-air micro-particle-induced X-ray/gamma emission (in-air µPIXE/PIGE) system to evaluate tooth-bound fluoride (T-F) in dentin following the application of fluoride-containing tooth-coating materials.

X-Ray Spectrometry, 2005 Abstract Two selected examples of PIXE microanalysis in ecophysiology are presented. Studies of heavy metal distributions in mycorrhizal and non‐mycorrhizal roots of Plantago lanceolata showed different filtration mechanisms of Zn/Pb and Fe/Mn, both enabling plants to cope ...

PIXE and Its Applications to Elemental Analysis
Quantum Beam Science, 2019 When charged particles collide with atoms, atomic inner shell electrons become ionized, producing characteristic X-rays. This phenomenon is called particle-induced X-ray emission (PIXE).
