Corrosion resistance enhancement of SAE 1020 steel after Chromium implantation by nitrogen ion recoil
(ABM, ABC, ABPol, 2005-12-01)
SAE 1020 construction steel is widely used as mortar reinforcement and small machine parts, but aside good surface properties as high ductility, hardness and wear resistance, its surface is prone to severe corrosion. As ...
Comparative studies of ion emission characteristics in a low energy Plasma Focus operating with different gas fillings
(IEEE, 2004)
The results of an investigation of ion emission from a low energy Plasma Focus (PF), operating at 20 kV, with 1.8 kJ stored energy, using several different gas fillings, including hydrogen, nitrogen, argon and methane, are ...
Characterization of extragalactic fast X-ray transients from X-ray archival searches
(2023)
Extragalactic fast X-ray transients (FXTs) are non-Galactic short flashes of X-ray photons (in the narrow range of ≈0.3–10 keV) of unclear origin that last a few minutes to hours. A variety of astronomical objects and ...
Morphological Properties of the Crab Nebula: A Detailed Multiwavelength Study Based on New VLA, HST, Chandra, and XMM-Newton Images
(IOP Publishing, 2017-04)
We present a detailed analysis of the morphological properties of the Crab Nebula across the electromagnetic spectrum based on new and previous high-quality data from radio to X-rays. In the radio range we obtained an image ...
Hard X-ray dosimetry of a plasma focus suitable for industrial radiography
(Pergamon-Elsevier Science Ltd, 2018-04)
Dosimetric measurements of the hard X-ray emission by a small-chamber 4.7 kJ Mather-type plasma focus device capable of producing neat radiographs of metallic objects, were carried out with a set of thermoluminescent ...
Experimental photon energy response of different dosimetric materials for a dual detector system combining thermoluminescence and optically stimulated luminescence
(Elsevier B.V., 2014-12-01)
Precise knowledge of the energy response of radiation detector materials is necessary for accurate dose measurements, because the usual TL and OSL material response relative to the medium of interest (air, water or tissue) ...
Estudo estrutural, morfológico, elétrico e óptico de cristais de a-Ag2WO4 dopados com Mo6+ via co-precipitação assistida por PVP
(Universidade Estadual Paulista (Unesp), 2015-09-22)
In this study were synthesized Mo6+ doped α-Ag2WO4 microcrystals at concentrations of 0, 0,1, 0,2 0,4 e 0,8% by co-precipitation at 100 ºC in presence of polyvinylpyrrolidone surfactant. Were obtained pale-yellow polycrystalline ...
Helium ion irradiation of polymer films deposited from TMS-Ar plasmas
(Wiley-Blackwell, 2007-05-23)
Polymer films synthesized from plasmas of a tetramethylsilane - Ar mixture were modified by irradiation with 170 keV He ions at fluences ranging from 1 x 10(14) to 1 x 10(16) cm(-2). As revealed by infrared spectroscopy, ...
