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...

Abstract To reduce or completely remove the viewing angle dependence of liquid crystal (LC) displays and devices, we have recently introduced a new electrode structure for LC displays. This has openings (holes) in pixel (PixE) generating fringe electric field with azimuthal degenerated distribution lines around each hole, resembling fountain. Such is promoting azimuthally switching molecules th...

The GUPIX package for processing particle-induced X-ray emission (PIXE) spectra has been updated and expanded, with emphasis on the 1–15 keV energy range accessed by silicon drift detectors. Several portions of database are modified or extended. existing mass attenuation coefficient (MAC) dataset is now partnered an alternative MAC which improves PIXE’s accuracy in analysis light elements. Diff...

This research is focused on investigating the biochemical mechanisms involved in neurovascular inflammation, cerebral hypoxia and altered cerebral metabolism, with particular focus on their role in the pathogenesis of cerebral malaria (CM) and acute bacterial meningitis (ABM). The pathogenesis of these diseases remains poorly understood, hindering the development of improved therapies. Previous...

This article presents the results obtained by measuring characteristic x-ray production cross sections arising from interaction of accelerated protons with target atoms (PIXE). The PIXE data were measured at excitation K-, L-, and M-shells in mass range Mg to Bi 1 MeV protons. We use approach based on calculation through Rutherford backscattering section, which can be calculated formula high ac...

Coarse and fine particulate matter were collected at a residential area at Vashi, Navi Mumbai and the filter samples were analysed for trace elements using PIXE technique. The trend of particulate matter showed higher concentrations during winter than the summer and monsoon concentration levels. High concentrations of elements related to soil and sea salt were found in PM10 and PM2.5. Also high...
