Abstract

In order to further investigate electron screening phenomenon we studied proton induced nuclear reactions over an energy range from 1.35 to 3.08 MeV for different environments: Ni metal and NiO insulator. The measurements were based on observation of the {gamma}-ray yields of {sup 59,61,63,64,65}Cu and {sup 58,60,62}Ni. Also, we have studied the decay of {sup 61}Cu produced in the reaction {sup 60}Ni(p,{gamma}), in order to find a possible decay rate perturbation by atomic electrons and found a small difference in half-life for metallic compared to oxide environment, respectively. The present results clearly show that the metallic environment affects the fusion reactions at low energy and that it might also affect the decay rate.

Electron screening in nickel

Journal Article Gajevic, Jelena; Lipoglavsek, Matej; Petrovic, Toni; ... - AIP Conference Proceedings

In order to investigate the interplay between nuclei and their surroundings we studied proton induced nuclear reactions over an energy range from 1.35 to 3.08 MeV for different environments: Ni metal and NiO insulator. The measurements were based on observation of the {gamma}-ray yields of {sup 59,61,63,64,65}Cu and {sup 58,60,62}Ni.

Comparative in vitro cytotoxicity of nickel oxides and nickel-copper oxides to rat, mouse, and dog pulmonary alveolar macrophages

Journal Article Benson, J; Henderson, R; Pickrell, J - J. Toxicol. Environ. Health; (United States)

Metal oxides containing either Ni alone (NiO's) or both Ni and Cu (Ni-CuO's) are encountered during Ni refining. Six NiO compounds calcined at temperatures ranging from < 650 to 1045/sup 0/ and four Ni-CuO's containing from 6.9 to 28% Cu and 44 to 69% Ni were screened for their in vitro cytotoxicity to alveolar macrophages (AM). NiO's were less toxic to rat AM than were the Ni-CuO compounds. The toxicity of the Ni-CuO compounds increased with increasing Cu content and decreasing Ni content of the molecules, indicating that the toxicity was due to the Cu content of the molecules.

Clarification of stress corrosion cracking mechanism on nickel base alloys in steam generators for their long lifetime assurance

Book Nagano, Hiroo; Kajimura, Haruhiko

Thermally treated (TT) Alloys 600 (16%Cr-8%Fe-bal.Ni) and 690 (30%Cr-10%Fe-bal.Ni) have been successfully used in the steam generators of operating pressurized water reactors (PWRs). This paper deals with intergranular stress corrosion cracking (IGSCC) mechanisms in Ni-base alloys in various corrosive environments such as deaerated water, air-saturated chloride medium, and caustic solutions at high temperatures with focus on Cr content and Cr carbide precipitation at grain boundaries in the alloys. Nickel base alloys of high purity, or with different Cr, C, and B contents with different heat treatments were put to various corrosion tests. SCC resistance of Alloy 600 is affected differentlymore »« less
Chemical and optical studies of electrochromic hydrated nickel oxide films and devices

Conference Lampert, C

Over the last few years, hydrated NiO or NiOH has gained interest as an electrochromic material. First it shows a transparent to bronze coloration which is suitable for a number of architectural, vehicle and aerospace glazing applications. This material is stable in an alkaline environment and colors and bleaches at potentials below 1.0V and below the oxygen and hydrogen evolution potentials. In this work the author discusses films made chiefly by anodic electrodeposition. The properties of films made by other deposition processes will be discussed. Much of the electrochemical knowledge about hydrated NiO comes from studies of metallic Ni electrodesmore »« less
Revisiting the conversion reaction voltage and the reversibility of the CuF2 electrode in Li-ion batteries

Journal Article Seo, Joon; Cho, Hyung-Man; Takahara, Katsunori; ... - Nano Research

Deviation between thermodynamic and experimental voltages is one of the key issues in Li-ion conversion-type electrode materials; the factor that affects this phenomenon has not been understood well in spite of its importance. In this work, we combine first principles calculations and electrochemical experiments with characterization tools to probe the conversion reaction voltage of transition metal difluorides MF2 (M = Fe, Ni, and Cu). We find that the conversion reaction voltage is heavily dependent on the size of the metal nanoparticles generated. The surface energy of metal nanoparticles appears to penalize the reaction energy, which results in a lower voltagemore »« less
