摘要：

[Figure Presented] Size matters: Both high-pressure and nanoscale syntheses can lead to the same indium oxide polymorph. Recent work by Farvid et al. provide an explanation; metastable high-pressure Hi-In2O3 is sta-bilized by surface forces in nanoscale particles, whereas in larger particles only the stable cubic C-In2O3 polymorph exists; this is evident in the energy diagrams. © 2010 Wlley-VCH Verlag GmbH & Co.
