Over the past years, diamonds, diamond films, and diamondlike carbon films have become of primary importance in many fields of new technology. Several practical applications of these materials have turned out to be commercially viable. However, alongside the attractive qualities of diamond materials, it must be noted that the growth of large diamond(More)
Simulation of beta particle transport from a Ni-63 radioisotope in silicon using the Monte Carlo N-Particle (MCNP) transport code for monoenergetic beta particle average energy, monoenergetic beta particle maximum energy, and the more precise full beta energy spectrum of Ni-63 were demonstrated. The beta particle penetration depth and the shape of the(More)
Two types of ammonium uranyl nitrate (NH4)2UO2(NO3)4 2H2O and NH4UO2(NO3)3, were thermally decomposed and reduced in a TG-DTA unit in nitrogen, air, and hydrogen atmospheres. Various intermediate phases produced by the thermal decomposition and reduction process were investigated by an X-ray diffraction analysis and a TG/DTA analysis. Both (NH4)2UO2(NO3)4(More)
Nuclear batteries based on silicon carbide betavoltaic cells have been studied extensively in the literature. This paper describes an analysis of design parameters, which can be applied to a variety of materials, but is specific to silicon carbide. In order to optimize the interface between a beta source and silicon carbide p-n junction, it is important to(More)
Results about nuclear reactions of deuterons in 2 pm distance was specified [1] in support of the experiments [2] for LENR based on an evaluation of results of Prelas et al. were a Coulomb screening by a factor 13 was derived [3]. These results were especially fitting the later results of ultrahigh density clusters fulfilling conditions of Bose-Einstein(More)
Diamond in nanoparticle form is a promising material that can be used as a robust and chemically stable catalyst support in fuel cells. It has been studied and characterized physically and electrochemically, in its thin film and powder forms, as reported in the literature. In the present work, the electrochemical properties of undoped and boron-doped(More)
