Study of influence of mobile phone irradiation to tooth enamel EPR spectra
(2017)The contribution of mobile phones influence on electron spin resonance (EPR) spectra formation and electromagnetic noise signal for accuracy of dose estimation on example of tooth enamel samples measurements was investigated for low dose range. The spectra of irradiated tooth enamel samples in doses from 0 to 500 mGy have been measured. The spectra have been processed by ...2023-12-04 -
SOFC: Prospects of development
(2017)One of the main conditions for the transition to hydrogen energy is development of reliable, high-performance and cost-effective fuel cells, in which chemical energy is converted directly into electrical energy. The advantages of solid oxide fuel cells (SOFC) are: high electrical efficiency (50 - 60)%, in cogeneration with thermal energy the efficiency may reach 90%, and high ...2023-12-04 -
Ionizing radiation as a powerful tool for modification of metallic nanostructures
(2017)This paper presents a case study of targeted modification of the structure and properties of zinc nanotubes ordered arrays by treatment with Xe +22 and Kr +17 swift heavy ions (SHI). Polyethylene terephthalate track-etched membranes (PET TeMs) with a pore density of (4 × 10 9 ) ions/cm 2 have been used as a template for electrochemical deposition of Zn. Scanning electron ...2023-12-04 -
Preparation and characterization of down-shifting film for silicon solar cell based on the stilben 420, PVA polymer and silver nanoparticles
(2017)We have developed method of preparation of luminescent polymer films based on polyvinyl alcohol (PVA), organic dyestilben 420 (St420) and silver nanoparticles (AgNPs). Concentration of St420 which provides most efficient luminescence quantum yield was determined for PVA film. It was found that addition of 10 nm AgNPs to St420 samples in PVA leads to increase of absorption ...2023-12-04 -
Neutron-removal cross sections of 6,8He, 8Li and 9,10Be nuclei
(2017)Neutron-removal cross-section ( σ−xn ) measurements of neutron-rich light nuclei were performed on the COMBAS fragment-separator with a multi-detector Si telescope at intermediate energies (22-34) MeV/nucleon. The removals of one neutron from 8 Li and 9 Be, two neutrons from 6 He and 10 Be and four neutrons from 8 He were observed from the reactions on a Si-CsI(Tl) telescope. ...2023-12-04 -
α-particle emission in the reaction 48Ca+Ta at Coulomb energy
(2017)Inclusive energy spectra have been measured for light charged particles emitted in the bombardment of Ta target by 48Ca ions at 261 MeV and 471 MeV. The reaction products were analyzed and detected by means of a ( ∆E × E ) telescope placed in the focal plane of a magnetic spectrometer located at forward angles with respect to the beam direction. In all the reactions studied ...2023-12-04 -
New insight into the cluster structure of 9Be by reactions with deuteron beam
(Eurasian Journal of Physics and Functional Materials, 2017)Angular distributions of protons, deuterons, tritons and alpha particles emitted in the reaction 2H + 9Be at E lab =19.5 MeV were measured with an aim to shed light on the internal cluster structure of 9 Be and to study possible cluster transfer of 5 He. The analyses suggest a significant contribution of five-nucleon transfer in the reaction channel 9Be ( d , 4He ) 7Li .2023-12-04 -
Effect of lithium doping on electrophysical and diffusion proper-ties of nonstoichiometric superionic copper selenide Cu1.75 Se
(Eurasian Journal of Physics and Functional Materials, 2017)The results of studies of the ionic conductivity and the conjugated chemical diffusion coefficients (CCDC) in the nonstoichiometric LixCu1.75Se (0 ≤ x ≤ 0.25) ternary alloys are presented. It has been observed that the values of the ionic conductivity of Cu1.75Se copper selenide decreases with lithium doping in general owing to increasing the the activation energy. The increasing ...2023-12-04
