Effect of nitric acid oxidation on the surface of hydrochars to sorb methylene blue: An adsorption mechanism comparison by Duy H Nguyen, Hai Nguyen Tran, Huan-Ping Chao, Chu-Ching Lin

“…Six adsorption mechanisms were elucidated, in which the electrostatic interaction and hydrogen bonding were identified as the primary methylene blue-hydrochar adsorptive interaction; furthermore, because the nitric acid modification process enhanced oxygen- and nitrogen-containing functional groups and unsaturated bonds on the surface of oxidized-hydrochars, the π – π and n – π interaction became minor pathways for methylene blue adsorption onto oxidized-hydrochars. …”

Improvement of Core Performance by Introduction of Moderators in a Blanket Region of Fast Reactors by Toshio Wakabayashi

“…An application of deuteride moderator for fast reactor cores is proposed for power flattening that can mitigate thermal spikes and alleviate the decrease in breeding ratio, which sometimes occurs when hydrogen moderator is applied as a moderator. Zirconium deuteride is employed in a form of pin arrays at the inner most rows of radial blanket fuel assemblies, which works as a reflector in order to flatten the radial power distribution in the outer core region of MONJU. …”
