“…The ascending board stopped instantly when the sensor recorded the indenter motion and then read the values. The tests were carried out at room temperature and humidity of 30-40 per cent for three replications of each sample to gain an average value (Elsaftawy et al, 2016).…”

Purpose This paper aims to evaluate the inhibitive effect and adsorption behavior of 5-(ethylthio)-1H-tetrazole (EHT) and 5-(benzylthio)-1H-tetrazole (BHT) on copper in a sulfur-ethanol system. Design Methodology Approach Evaluation was carried out using electrochemical measurement and surface analysis techniques. Measurements of static friction coefficient by scanning electron microscopy and contact angle analysis were applied and finally confirmed the existence of the adsorbed film. The inhibitive mechanism of the two compounds was evaluated by means of quantitative calculation and molecular dynamics simulation. The friction coefficient of corrosion surface before and after adding corrosion inhibitor was determined through static friction coefficient measurements. Findings The electrochemical measurement indicated that the most effective concentration of two corrosion inhibitors was 70 mg L–1, while the inhibition efficiency of that was EHT > BHT. The friction coefficient data showed that the addition of corrosion inhibitor reduced the roughness of the corrosion surface. Adsorption behavior of two inhibitors followed the Langmuir’s adsorption isotherm and was attributed to mixed-type adsorption. The results of quantitative calculation and molecular dynamics simulation showed that tetrazole rings of the two inhibitors and its connected S atoms were adsorbed on Cu(111) surface in parallel. Originality Value The corrosion inhibition performance of two tetrazolium derivatives in a sulfur-ethanol system was studied by combining experiments with theory, which provided a theoretical basis for the future research.

“…The interest in the irradiation of polymers with high energy ions originated from their ability to register nuclear tracks and the applications of polymers as particle detectors or as membranes, which are widely described in the literature [4] [5] [6]. Radiation damage can be measured by a number of different methods, including the solid state nuclear track detector as gamma-ray dosimeter [7]. Generally, the radiation interactions with plastic detectors causes a reduction in the average molecular weight of the latter, which subsequently produces an enhancement in the bulk due to high energy radiation as the γ-dose increases [8].…”

The effect of ion implantation, including Ar + ion with influences (1 × 10 13-10 15 ions/cm 2), on the electrical and optical properties of ultrahigh molecular weight polyethylene (UHMWPE) were investigated with particular emphasis placed on the sensor performance to be used in the field of radiation detection. The obtained results focusing on the effect of the different influences showed a significant change in the electrical conductivity, capacitance and loss tangent. The absorption spectra for UHMWPE samples were recorded and the values of the allowed direct and indirect optical energy gap (E opt) d , (E opt) in of UHMWPE and energies of the localized states for the virgin and implanted samples were calculated. We found that the optical energy gap values decreased as the radiation dose increased. The results can be explained on the basis of the ion beam radiation-induced damage in the linear chains of UHMWPE, with cross-linking generated after implantation. The observed changes in both the optical and the electrical properties suggest that the UHMWPE film may be considered as an effective material to achieve ionradiation detection at room temperature.

“…Synthesis of different substances during irradiation of polymers had been reported by our group [1][2][3][4]. The main product is water-free molecules, carbon oxides and alcoholic compounds with OH − group attached to scissor chain radical [5][6][7]. The processes of formation of organic compounds in irradiated samples are associated with the chain scissoring, re-polymerization and cross linking and atomic displacements [1,2,8,9].…”

The late effect of radiation-induced modifications in polymeric material was investigated. The research focused on two morphologies of the polymer material, being either soft-optical structure or fibrous structures that represent a number of biological tissues and industrial materials. The aging effect was investigated by examining the formation of resin at the surface and within the fiber of the polymeric material. Micro-hardiness test was used to investigate the surface of the PADC and Bayfol samples using the effect of indention time. Optical microscope imaging was used to determine the extension of the organic resin on the surface of the PADC sample and to explain discrepancies in the hardness measurements. Polarizing optical microscope showed change in polarization in Bayfol samples as a result of indention stress and with conjunction to radiation dose. Layers of radiation-induced compounds in poly-allyl diglycole carbonate (PADC) and intercalated synthesized compounds within Bayfol polymer fiber were found. Infrared absorption showed loss of free O-H groups of PADC samples and C=O group of Bayfol samples and prove that aromatic composition of Bayfol was more sensitive to radiation damage than aliphatic PADC composition. Results verified the aging effect and showed behaviors that reflect the action of radiation-induced modification long time after irradiation.
