Aerosols play an important role in the atmosphere but are poorly characterized, particularly in urban areas like the Mexico City Metropolitan Area (MCMA). The chemical composition of urban particles must be known to assess their effects on the environment, and specific particulate emissions sources should be identified to establish effective pollution control standards. For these reasons, sampl...

For several years, the specific features of PIXE and PIGE have made them very attractive in the field of archaeometry. Among them, non-destructivity is one of the most important. The possibility of working under atmospheric pressure is also important because of the very different shapes and sizes of the artefacts concerned. However, these ion beam techniques suffer from the same disadvantage: t...

Forensic anthropologists use various methods to determine the type of weapons used in cases involving a dismembered body. For this study PIXE (particle-induced x-ray emission) analysis was performed on samples taken from pieces of pig bone cut with three different hacksaw blades. The analysis was used to determine if the blades left any elemental residue on the bone. When the results of the PIX...

Simple methods for the determination of elements in biological fluids have been developed. It is important to quantify accidental incorporation radionuclides during decommissioning work at nuclear power plants. Herein, we proposed simple preparations and uranium concentrations urine microbeam scanning particle induced X-ray emission (µ-PIXE) analysis a rat model. A droplet (1 µL) mixed solution...

A bronze wine vessel attributed to 1600–1046 B.C., Shang dynasty in China, an object from the East Asian Collection of Museum Applied Arts and Sciences Sydney (Australia), was studied using a non-destructive scientific analytical protocol based on synergic combination nuclear techniques. Gamma spectrometry, neutron-computed tomography, proton-induced X-ray emission (PIXE) spectroscopy were appl...

Trace elements concentrations of Ca, Fe, and Zn in cataractous human lenses have been determined using the proton induced X-ray emission technique (PIXE). The technique was selected due to its sensitivity and only modest requirements for sample material processing and preparation. In the study a statistically significant sample of post–surgery (phacoemulsification method) human lenses with cata...
