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 ...

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.

In-Air Micro-PIXE Mapping with Chemical Contrast. [PDF]

Anal Chem
Currently, 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 ...

Micro‐PIXE in ecophysiology

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 ...

Elemental analysis of lung tissue particles and intracellular iron content of alveolar macrophages in pulmonary alveolar proteinosis

Respiratory Research, 2011
Background Pulmonary alveolar proteinosis (PAP) is a rare disease occurred by idiopathic (autoimmune) or secondary to particle inhalation. The in-air microparticle induced X-ray emission (in-air micro-PIXE) system performs elemental analysis of materials
