Belt holes : By heating chromium under an ethanol atmosphere, nanobelts and nanorods of oxygen‐deficient chromia (Cr 2 O 3− x ) are prepared for the first time (see image). The nanobelts exhibit two types of superlattice structures that arise from different orderings of the oxygen defects. Folding observed in some of the nanobelts is a result of twinning.
