Notizen: Magnetic properties of Cd1−yMnyS nanocrystals have been studied. They vary with the particle size and markedly differ from those observed in the bulk phase, in particular their interactions drastically increase compared to those observed in the latter case. A Mn2+–Mn2+ interaction enhancement with decreasing size involves changes in the magnetic phase diagram. For 4 nm nanocrystals, a spin glass phase can be assumed. © 2000 American Institute of Physics.

Notizen: [Auszug] THE cause of the apparent gain in the ascorbic acid content of vegetables brought about by cooking has given rise to much correspondence in these columns. An attempt has been made in this laboratory to explain this phenomenon along the lines of either the ‘combined ascorbic acid’ or ‘oxidase’ ...
