Innovative preparation route for uranium carbide using citric acid as a carbon source
No full textThe preparation of uranium carbide (UC) by carbothermal reduction and its sintering into dense pellets by conventional means require high temperatures for long periods. We have developed a preparation route yielding fine UC powder with significantly increased sinterability. At first, a mixture of nanocrystalline UO2 embedded in amorphous carbon (nano-UO2/C) was obtained by thermal decomposition of a gel containing solubilised uranyl nitrate and citric acid. Later, the nano-UO2/C powder was treated in a conventional furnace or in a modified spark plasma sintering facility at elevated temperatures (≥1200°C) in order to obtain uranium carbide powder. The effects of initial composition, temperature, gas/vacuum atmosphere and the overall reaction kinetics are reported

Garuccio-Rapisarda-Vigier Experiment Revisited
No full textWe propose a setup for the experimental implementation of the conceptual experiment proposed, in 1982, by Garuccio, Rapisarda and Vigier. In particular, we show that orthodox quantum mechanics leads to a different prediction with respect to the nonlinear causal approach. Hence, this experiment shall contribute to clarify the ontic nature of quantum wave
Experimental investigation and thermodynamic modelling of the ThF4-PuF3 phase diagram
No full textPhase equilibria in the system ThF4-PuF3 were measured by DSC. Samples were encapsulated to prevent leak during the measurements and to protect the internal parts of the device from the corrosive fluoride vapours. Formation of intermediate compounds and solid solutions was investigated by XRD. A thermodynamic model based on CALPHAD approach was developed for the measured system. Good fit between measurements and phase equilibria calculated using the model was achieved
On a contradiction between the classical (idealised) quantum theory of measurement and the conservation of the square of the total angular momentum in the Einstein-Podolsky-Rosen paradox
No full textSpark plasma sintering of fine uranium carbide powder
No full textAbstractResults of uranium carbide sintering using a spark plasma sintering facility are presented here. The initial uranium carbide powder is produced from the thermal decomposition of a citric acid and uranium nitrate mixture. The study shows that spark plasma sintering is a very efficient compaction tool for uranium carbide material. Both onset of sintering and final density are strongly correlated to the UC synthesis conditions
Possible experimental test of the causal stochastic interpretation of quantum mechanics: physical reality of de Broglie waves

No full text8th Symposium Honoring Mathematical Physicist Jean-Pierre Vigier
No full textA truly Galilean class volume as it also introduces a new method in theory formation this time completing the tools of epistemology. This book covers a broad spectrum of theoretical and mathematical physics by researchers from over 20 nations from four continents. Like Vigier himself, the Vigier symposia are noted for addressing avant-garde cutting-edge topics in contemporary physics. Among the six proceedings honoring J-P Vigier this is perhaps the most exciting one as several important breakthroughs are introduced for the first time. The most interesting breakthrough in view of the recent NIST experimental violations of QED is a continuation of pioneering work by Vigier on Tight Bound States in Hydrogen. The new experimental protocol described not only promises empirical proof of large-scale extra dimensions in conjunction with avenues for testing string theory but also implies the birth of the field of Unified Field Mechanics ushering in a new age of discovery. Work on quantum computing redefines the qubit in a manner that the uncertainty principle may be routinely violated; other breakthroughs occur in the utility of quaternion algebra in extending our understanding of the nature of the fermionic singularity or point particle. There are several other discoveries of equal magnitude making this volume a must-have acquisition for the library of any serious forward-looking researchers
