Nuclear fusion technologies have re-gained momentum in the last decade thanks to their disruptive potential different fields, such as energy production and space propulsion, new technological developments, especially high temperature superconductor tapes, which allow overcoming previous performance or design limits. To date, reviews of recent nuclear designs are lacking. Therefore, this paper a...
Describing fusion reactions between O and Dy and, between O and Sm by the sd− and sdf− interacting boson model, we show that heavy-ion fusion reactions are strongly affected by anharmonic properties of nuclear surface vibrations and nuclear shape, and thus provide a powerful method to study details of nuclear structure and dynamics.
From a Twin Universe perspective, it is proposed that stellar nuclear fusion can account for the negative-energy pressure (Dark Energy) that drives our present-day accelerated cosmic expansion. In the mirror twinned universe all processes are duplicated but with reverse negative polarity. Both the Positive and Negative Universes exist on the opposing surfaces of a topological two-dimensional me...
Eukaryotic initiation factor 5A (eIF-5A) is the only protein in nature that contains hypusine, an unusual amino acid residue formed posttranslationally by deoxyhypusine synthase and deoxyhypusine hydroxylase. Although the eIF-5A gene is essential for cell survival and proliferation, the precise function and localization of eIF-5A remain unclear. In this study, we have determined the subcellular...
Abstract This chapter introduces the reader to fundamentals and reasoning for exploring fusion energy. Fusion, reaction of two hydrogen atoms colliding, is process that powers Sun stars. Fusion works by turning small amounts matter into vast If realized on Earth, nuclear could solve global energy demands generations come.
In this research, the applicability of several metal hydrides as neutron moderator and shielding for D-D fusion sources has been investigated by MCNPX code. The results have been investigated in three steps to find the materials with lower thermal, fast and total neutron fluxes than conventional shielding materials. The results show relative advantages of LaNi5H6, VH, TiH2, TaH, Mg (BH4)2, YH2,...
