Anomalous Exothermic And Endothermic Data Observed By Nano-Ni-Composite Samples

To study the anomalous heat effect of Ni-based binary-metal-nano-powder samples by gas-phase hydrogen isotope absorption/ desorption, three kinds of samples CNZ, CNZ-II and NZ were tested for the temperature range 300-573 K. The highest excess heat power, ca. 2W/g-Ni was obtained with CNZ at 573 K. A peculiar H(D)-isotopic effect and sudden endothermic events caused by abrupt H(D)-desorption were observed. The heat phenomenon appears to be happening on surface of nano-particles. (C) 2015 ISCMNS. All rights reserved.
