We model fullerene nanocages filled with hydrogen, of the general formula Hn@Ck, and study the capacity of such endohedral fullerenes to store hydrogen. It is shown using density functional theory that for large numbers of encapsulated hydrogen atoms, some of them become chemisorbed on the inner surface of the cage. A maximum of 58 hydrogen atoms inside a C60 cage is found to still remain a met...

THE POOR QUALITY of reagent chemicals in the United States by 1916 led to the statement by Hillebrand (1) that “the situation is particularly deplorable just now.” In 1919, to overcome the handicap of poor reagent chemicals, representatives of iiidustry, together with representatives of reagent users, undertook jointly under the sponsorship of the American Chemical Society, the task of establis...

should be selected primarily with a view to furnishing enjoyment by growth of knowledge about the history of our subject. The topics of this list may also be suitable subjects for consideration at meetings of mathematical clubs. In fact, it is especially important that the subjects selected for such nmetings should be fertile, since those who take active part in them include to a large extent t...
